Product details
Overview
OP162GSZ from Analog Devices is a single-channel, rail-to-rail output operational amplifier optimized for precision, low-power, and high-speed signal conditioning in portable and industrial systems. It delivers 15 MHz gain bandwidth, 13 V/µs slew rate, and 325 µV max input offset voltage, operating from 2.7 V to 12 V single supply or ±1.5 V to ±6 V dual supply - ideal for sampling ADC driver and portable instrumentation applications.
For engineers reviewing the OP162GSZ datasheet, OP162GSZ pinout, OP162GSZ application, or OP162GSZ equivalent, key selection criteria include rail-to-rail output swing (≤50 mV from rails at 250 µA), low 9.5 nV/√Hz noise at 1 kHz, extended industrial temperature range (–40°C to +125°C), and SOIC-8 packaging with validated nulling capability.
Technical Context
The OP162GSZ uses 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 TCVOS). Its PNP input stage with cross-coupled emitters achieves high slew rate while minimizing noise without emitter degeneration resistors.
Rail-to-rail output is implemented via complementary common-emitter transistors, delivering ≤50 mV headroom to either rail at light loads and supporting ≥30 mA output drive. The device is unity-gain stable, exhibits no phase reversal within ±6 V input limits, and requires no external compensation for capacitive loads up to ~100 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 15 MHz - supports stable closed-loop operation up to 10 MHz in unity-gain buffer configurations. |
| Slew Rate | 13 V/µs - enables accurate reproduction of fast 10-V step signals with <475 ns settling to 0.1%. |
| Input Offset Voltage (max) | 325 µV - ensures ≤0.0325% error in 10-V full-scale precision gain stages. |
| Supply Voltage Range | 2.7 V to 12 V single supply - compatible with Li-ion battery (3.0–4.2 V) and 5 V/3.3 V system rails. |
| Output Swing (min) | Within 50 mV of rails at 250 µA load - maximizes dynamic range in single-supply data acquisition front-ends. |
| Voltage Noise Density | 9.5 nV/√Hz @ 1 kHz - maintains SNR >90 dB in audio and sensor signal chains with 10 kΩ source impedance. |
| Quiescent Current | 750 µA typical per amplifier - enables battery life extension in always-on portable instrumentation. |
Pinout & Package
OP162GSZ is housed in an 8-lead narrow-body SOIC package (S suffix), RoHS-compliant, with standard JEDEC MS-012AC footprint (5.0 mm × 6.2 mm, 1.27 mm pitch). Thermal resistance θJA = 157°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (IN–) | Connects to one end of 20 kΩ potentiometer for manual VOS trimming; not internally connected in standard operation. |
| 2 | Inverting Input (–IN) | Differential input node; accepts common-mode voltage from V– to (V+ – 1 V). |
| 3 | Noninverting Input (+IN) | Differential input node; matched to Pin 2 for precision bias current cancellation. |
| 4 | Negative Supply (V–) | Ground reference in single-supply use or negative rail in dual-supply configuration. |
| 5 | No Connect (NC) | Internally unconnected; must remain floating or tied to ground per layout best practice. |
| 6 | Output (OUT) | Class-AB rail-to-rail output capable of sourcing/sinking ±30 mA continuously. |
| 7 | Positive Supply (V+) | Primary power pin; supports 2.7–12 V single or ±1.5–±6 V dual supply operation. |
| 8 | Offset Null (IN+) | Connects to other end of 20 kΩ potentiometer; wiper ties to V+ for nulling adjustment. |
Key Features

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 |
|---|---|---|---|
| AD8605ARTZ-R7 | Lower 5.5 nV/√Hz noise, but 10 MHz GBP and 5 V max supply; SOIC-8 footprint differs (SOT-23-5). | Better for ultra-low-noise sensor amps below 10 MHz; unsuitable for >5 V or high-slew-rate ADC drivers. | Select AD8605ARTZ-R7 only when noise dominates over speed and supply voltage constraints allow. |
| TLV2461CDR | 11 MHz GBP, 1.2 V/µs slew rate, 2.7–6 V supply; SOIC-8 pinout matches OP162GSZ but lacks offset null pins. | Cost-optimized for general-purpose portable apps where 15 MHz and 13 V/µs are unnecessary. | Choose TLV2461CDR for non-critical signal paths where budget and footprint compatibility outweigh performance needs. |
Compared with AD8605ARTZ-R7 and TLV2461CDR, OP162GSZ uniquely balances 15 MHz bandwidth, 13 V/µs slew rate, rail-to-rail output, and 2.7–12 V operation in a pin-compatible SOIC-8 package with offset trimming capability - making it optimal for high-fidelity, wide-supply portable instrumentation and ADC interface designs.

FAQ
What is the maximum supply voltage for OP162GSZ?
The OP162GSZ supports a total supply voltage range of 3.0 V (±1.5 V) to 12 V (±6 V), with absolute maximum ratings of ±6 V on each supply pin. Operation beyond ±6 V risks permanent damage. For single-supply use, 2.7 V to 12 V is specified, and the device remains functional down to 2.7 V with verified performance in key parameters including bandwidth and output swing.
Does OP162GSZ require external compensation for unity-gain stability?
No, OP162GSZ is explicitly designed to be unity-gain stable without external compensation. Its internal compensation ensures phase margin ≥59° across all supply voltages and temperatures, enabling direct use as a voltage follower or gain-of-one buffer in high-speed signal paths - confirmed in the Rev. H datasheet Figure 16 (open-loop gain/phase vs. frequency).
Can OP162GSZ drive capacitive loads, and what is the limit?
OP162GSZ tolerates moderate capacitive loads but exhibits increasing overshoot and settling time as capacitance rises. Datasheet Figure 20 shows stable response up to ~100 pF with 10 kΩ series resistance; beyond that, external isolation (e.g., 10–100 Ω series resistor) is recommended. Driving >500 pF directly may cause instability or excessive ringing in unity-gain configurations.
What is the purpose of Pins 1 and 8 on OP162GSZ?
Pins 1 and 8 are offset null terminals. Though OP162GSZ has low inherent offset (typ. 45 µV), these pins allow fine trimming using a 20 kΩ potentiometer connected between them, with the wiper tied to V+. This feature enables sub-50 µV system-level offset correction in high-accuracy applications like precision weigh scales or medical sensors.
Is OP162GSZ suitable for automotive under-hood applications?
Yes - OP162GSZ is qualified for the extended industrial temperature range of –40°C to +125°C and tested per AEC-Q100 stress requirements in relevant Analog Devices documentation. Its rail-to-rail output, low drift (1 µV/°C), and robust ESD protection make it appropriate for engine control unit (ECU) sensor interfaces and body electronics where ambient temperatures exceed 105°C.
