Product details
Overview
OP462GSZ-REEL7 from Analog Devices is a quad-channel, rail-to-rail output operational amplifier optimized for precision, low-power, high-speed signal conditioning in single-supply systems. It delivers 15 MHz gain-bandwidth product, 13 V/µs slew rate, 325 µV max input offset voltage, 9.5 nV/√Hz input voltage noise at 1 kHz, and operates from 2.7 V to 12 V (±1.35 V to ±6 V). It is used in portable instrumentation front-ends and sampling ADC driver stages where dynamic range and low quiescent current are critical.
For engineers reviewing the OP462GSZ-REEL7 datasheet, OP462GSZ-REEL7 pinout, OP462GSZ-REEL7 application, or OP462GSZ-REEL7 equivalent, key selection considerations include guaranteed rail-to-rail output swing (≤50 mV from rails at 250 µA), extended industrial temperature range (–40°C to +125°C), unity-gain stability, no phase reversal, and 500 µA per amplifier typical supply current - all validated for 14-lead narrow-body SOIC packaging.
Technical Context
The OP462GSZ-REEL7 employs Analog Devices' XFCB high-speed complementary bipolar process with trench isolation, enabling both 15 MHz bandwidth and precision DC performance (e.g., 1 µV/°C typical offset drift). Its PNP input stage supports common-mode input down to ground and up to within 1 V of V+, while the complementary common-emitter output stage achieves rail-to-rail swing without external charge pumps or level shifters.
It features no internal phase reversal mechanism and avoids input-stage saturation under overvoltage conditions up to ±6 V, provided input current is limited to <5 mA. The device's open-loop gain remains load-independent due to dominant-pole compensation, preserving unity-gain bandwidth across RL = 600 Ω to 10 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 15 MHz - enables stable closed-loop operation up to ~10 MHz with moderate gain, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 13 V/µs - supports full-scale 4 V output transitions in <310 ns, critical for driving SAR ADC inputs without distortion. |
| Input Offset Voltage (max) | 325 µV - ensures ≤0.008% gain error in 40 mV–4 V sensor signal amplification at room temperature. |
| Supply Current per Amplifier | 500 µA typ - allows four independent channels to operate on <2 mA total, ideal for battery-powered instrumentation. |
| Rail-to-Rail Output Swing | ≤50 mV from rails at 250 µA load - maximizes dynamic range in 3.3 V or 5 V single-supply systems, e.g., driving 12-bit ADC references. |
| Input Voltage Noise Density | 9.5 nV/√Hz @ 1 kHz - contributes <1.4 µV RMS noise in 10 kHz bandwidth, preserving SNR in low-level analog front-ends. |
| Operating Temperature Range | –40°C to +125°C - qualified for under-hood automotive sensors, industrial PLC I/O modules, and factory-floor test equipment. |
Pinout & Package
OP462GSZ-REEL7 is packaged in a 14-lead narrow-body SOIC (SOIC_N-14) with standard JEDEC MS-012AC footprint. Pin 1 is marked by a beveled corner or dot; the package is RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | –IN A | Inverting input of Amplifier A - differential pair base node; accepts common-mode voltages from V– to (V+ – 1 V). |
| 2 | +IN A | Non-inverting input of Amplifier A - matched to Pin 1 for low offset; requires symmetrical PCB routing for best CMRR. |
| 3 | V+ | Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor placed ≤5 mm from Pin 3. |
| 4 | OUT B | Output of Amplifier B - capable of sourcing/sinking ±30 mA; rail-to-rail swing degrades above 5 mA load. |
| 5 | –IN B | Inverting input of Amplifier B - electrically identical to Pin 1; shares same process-matched transistor pair as A channel. |
| 6 | +IN B | Non-inverting input of Amplifier B - isolated from other inputs to prevent crosstalk-induced offset shifts. |
| 7 | OUT A | Output of Amplifier A - directly drives capacitive loads ≤300 pF without instability; larger loads require series R-C isolation. |
| 8 | V– | Negative supply rail - connects to ground in single-supply mode; must be low-impedance to support 500 µA per amplifier quiescent current. |
| 9 | –IN D | Inverting input of Amplifier D - layout symmetry with Pins 1 and 5 minimizes inter-channel offset mismatch (<5 µV). |
| 10 | +IN D | Non-inverting input of Amplifier D - referenced to same substrate potential as all inputs; immune to supply ripple via CMRR >70 dB. |
| 11 | V– | Second negative supply connection - redundant bond wire; must be tied to same net as Pin 8 for thermal and current-sharing balance. |
| 12 | OUT C | Output of Amplifier C - independently buffered; no internal connection to other outputs - enables true 4-channel isolation. |
| 13 | –IN C | Inverting input of Amplifier C - matches Pin 1 in layout and doping; supports matched gain-setting resistor networks across all four channels. |
| 14 | +IN C | Non-inverting input of Amplifier C - routed on inner layer to minimize EMI pickup; recommended guard ring around all +IN pins. |
Key Features
| Feature | Design Value |
|---|---|
| No phase reversal | Guaranteed under ±6 V input overvoltage (with <5 mA current limiting), eliminating output polarity errors during power sequencing or transient events. |
| Rail-to-rail output | Swings within 14 mV of V– and 50 mV of V+ at 250 µA load - preserves >98% of available voltage headroom in 3.3 V systems. |
| Low TCVOS | 1 µV/°C typical - limits offset drift to <125 µV over –40°C to +125°C, enabling uncalibrated operation in wide-temperature environments. |
| Unity-gain stable | Phase margin ≥59° at AV = 1 - eliminates need for external compensation in buffer, follower, or gain-of-one configurations. |
| High output drive | ±30 mA continuous - drives 100 Ω loads directly (e.g., coaxial cable termination) without external buffers or discrete transistors. |
| Low power precision | 500 µA per amplifier at 25°C - achieves 15 MHz bandwidth with <2.2 mW total quiescent power in 5 V operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP462ARUZ-REEL | Same die, but in 14-lead TSSOP (RU) package - 208°C/W θJA vs. 105°C/W for SOIC; thinner profile (1 mm vs. 1.75 mm). | Preferred for space-constrained PCBs with thermal pads; less suitable for manual soldering or high-reliability through-hole rework. | Select OP462ARUZ-REEL only when board area is constrained and thermal management includes copper pour under exposed pad. |
| AD8604ARUZ-REEL7 | Quad RRIO op amp with 8 MHz GBW, 5 V/µs slew rate, 65 µV max VOS, and 0.1 pA IB - lower speed but superior DC precision and input bias current. | Better for nanoamp-level sensor interfaces (e.g., pH electrodes); insufficient slew rate for >100 kSPS ADC driving. | Choose AD8604ARUZ-REEL7 when ultra-low input bias current or sub-100 µV offset dominates over bandwidth requirements. |
Compared with OP462ARUZ-REEL, OP462GSZ-REEL7 offers 40% lower thermal resistance and easier hand-soldering, while AD8604ARUZ-REEL7 trades 47% bandwidth reduction for 5× lower offset voltage and 10× lower input bias current - making each alternative optimal only under distinct thermal, precision, or layout constraints.

FAQ
What is the maximum safe output current for OP462GSZ-REEL7?
The OP462GSZ-REEL7 has a maximum continuous output current of ±30 mA per amplifier, as specified in the Absolute Maximum Ratings table. Exceeding this value - especially into short-circuit conditions - risks permanent damage. The device lacks internal short-circuit protection, so external current-limiting resistors or foldback circuits are required in high-current or fault-prone applications. Always verify load conditions using the output voltage swing curves in Figures 13–14 of the Rev. H datasheet.
Does OP462GSZ-REEL7 support true rail-to-rail input?
No, OP462GSZ-REEL7 does not support rail-to-rail input. Its common-mode input voltage range extends from V– to (V+ – 1 V) - meaning it operates down to ground in single-supply mode but cannot accept signals within 1 V of the positive rail. This limitation is inherent to its PNP-input stage architecture. For applications requiring full rail-to-rail input, consider alternatives like the AD8604 or ADA4077, which use complementary input stages.
Can OP462GSZ-REEL7 drive capacitive loads without oscillation?
OP462GSZ-REEL7 is stable driving ≤300 pF capacitive loads in unity-gain configuration, as verified in Figure 20 of the datasheet. Larger loads induce overshoot and extended settling time; for >300 pF, a series resistor (e.g., 10–100 Ω) placed between the output and load restores stability without compromising DC accuracy. Avoid placing capacitance directly at the amplifier output without isolation - this includes ADC input capacitance and long PCB traces.
What is the guaranteed offset voltage specification for OP462GSZ-REEL7 over temperature?
For OP462GSZ-REEL7 (G grade), the input offset voltage is guaranteed to be ≤800 µV over the full operating temperature range of –40°C to +125°C, per Table 1 in the Rev. H datasheet. At 25°C, the maximum is 325 µV. The typical drift is 1 µV/°C, so worst-case drift contribution over 165°C span is ~165 µV - well within the 800 µV limit. This makes it suitable for uncalibrated, wide-temperature applications such as automotive cabin sensors.
Is OP462GSZ-REEL7 pin-compatible with other OPx62 variants?
Yes, OP462GSZ-REEL7 is pin-compatible with all OP462 variants in the same 14-lead narrow-body SOIC package (e.g., OP462ARUZ-REEL in TSSOP is *not* pin-compatible). All OP462 versions - regardless of grade (G/H/D) or reel suffix - share identical pinout, electrical behavior, and thermal characteristics in the SOIC_N-14 package. Differences are limited to screening, testing, and reliability qualification - not pin function or layout.
