Product details
Overview
OP462GSZ from Analog Devices is a quad-channel, rail-to-rail output operational amplifier optimized for precision, low-power, high-speed signal conditioning in single- or dual-supply systems. It delivers 15 MHz gain bandwidth, 13 V/µs slew rate, and 325 µV max input offset voltage across –40°C to +125°C, enabling accurate buffering of sampling ADC inputs and portable instrumentation front-ends.
For engineers reviewing the OP462GSZ datasheet, OP462GSZ pinout, OP462GSZ application, or OP462GSZ equivalent, this page provides verified electrical specifications, package mapping to 14-lead narrow-body SOIC (S suffix), thermal derating guidance, rail-to-rail output behavior under load, and validated alternative options for precision amplifier selection.
Technical Context
The OP462GSZ employs Analog Devices' XFCB high-speed complementary bipolar process with trench isolation, enabling both 15 MHz unity-gain bandwidth and <1 µV/°C offset drift without sacrificing dc precision. 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 - 4.95 V high and 14 mV low at 250 µA load - with ±30 mA drive capability.
It operates from 2.7 V to 12 V single supply or ±1.35 V to ±6 V dual supply, features no phase reversal up to ±6 V input overvoltage, and maintains stability at unity gain. The device is specified across the extended industrial temperature range (–40°C to +125°C) and exhibits 9.5 nV/√Hz voltage noise density at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 15 MHz - enables stable closed-loop operation up to 10 MHz at moderate gains for anti-aliasing or reconstruction filters. |
| Slew Rate | 13 V/µs - supports full-scale 2 V step settling in ≤475 ns, critical for driving SAR ADC sample-and-hold inputs. |
| Input Offset Voltage (max) | 325 µV - ensures ≤0.008% gain error in 12-bit precision applications without trimming. |
| Rail-to-Rail Output Swing | 4.95 V high / 14 mV low @ 250 µA (5 V supply) - maximizes dynamic range in low-voltage data acquisition systems. |
| Supply Current per Amplifier | 500–700 µA typ (5 V) - allows four amplifiers to operate within 2.8 mA total, suitable for battery-powered instrumentation. |
| Input Voltage Noise Density | 9.5 nV/√Hz @ 1 kHz - preserves SNR in sensor interfaces where source impedance is <10 kΩ. |
| Operating Temperature Range | –40°C to +125°C - qualified for under-hood automotive, industrial control, and harsh-environment embedded systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8604ARUZ | Lower 5.5 MHz GBW, 5 V/µs slew rate; 65 µV max offset; 50 µA/channel supply current. | Better offset and lower power, but insufficient speed for >500 kSPS ADC driving or wideband filtering. | Select when ultra-low power (<200 µA/channel) and sub-100 µV offset outweigh bandwidth needs. |
| TSV914IDT | 16 MHz GBW, 10 V/µs slew rate; 1.3 mV max offset; 80 µA/channel supply current; only rated to +105°C. | Higher bandwidth than OP462GSZ but significantly higher offset and narrower temperature range. | Select for cost-sensitive consumer applications requiring >10 MHz bandwidth but not extended temperature operation. |
Compared with AD8604ARUZ and TSV914IDT, OP462GSZ uniquely balances 15 MHz bandwidth, 325 µV max offset, rail-to-rail swing, and –40°C to +125°C qualification - making it the only option among the three qualified for high-accuracy, high-speed industrial sensing with full temperature coverage.

FAQ
What is the maximum operating supply voltage for OP462GSZ?
The OP462GSZ supports a single-supply range of 2.7 V to 12 V or dual-supply range of ±1.35 V to ±6 V. Absolute maximum supply voltage is ±6 V - exceeding this risks permanent damage. Operation at 12 V single supply is valid and commonly used in industrial sensor interfaces where headroom is needed before rail-to-rail output clipping.
Does OP462GSZ require external compensation for unity-gain stability?
No, OP462GSZ is unity-gain stable and requires no external compensation components. Its internal compensation ensures phase margin ≥59° across all supply voltages and temperatures, supporting reliable operation in voltage-follower, inverting amplifier, and active filter configurations without added capacitors or resistors.
Can OP462GSZ drive capacitive loads, and what is the recommended limit?
OP462GSZ can drive moderate capacitive loads, but performance degrades above ~100 pF: unity-gain bandwidth decreases, overshoot increases, and settling time lengthens. For loads >100 pF, a series resistor (e.g., 10–50 Ω) placed between output and capacitance restores stability - confirmed in Figure 20 of the Rev. H datasheet.
What is the thermal resistance (θJA) of OP462GSZ in its 14-lead SOIC package?
The OP462GSZ in 14-lead narrow-body SOIC (S suffix) has a junction-to-ambient thermal resistance (θJA) of 105°C/W, as specified in Table 5 of the Rev. H datasheet. This value assumes standard JEDEC 2-layer board conditions; actual θJA improves with PCB copper area and thermal vias.
How should unused amplifiers be configured in the OP462GSZ quad package?
Analog Devices recommends configuring unused amplifiers as unity-gain followers: connect the inverting input to the output with a 1 kΩ resistor, and tie the non-inverting input to ground. This minimizes quiescent current variation, prevents oscillation, and avoids input stage saturation - detailed in the "Unused Amplifiers" section (Page 14) of the OP462 datasheet.
