Product details
Overview
OP90GSZ-REEL from Analog Devices is a precision low-voltage micropower operational amplifier in 8-lead SOIC_N (R-8) package, featuring 150 µV max input offset voltage, 20 µA max supply current, and rail-to-rail output swing down to ground in single-supply operation. It supports 1.6 V to 36 V single or ±0.8 V to ±18 V dual supplies and is used in battery-powered voltage references, current monitors, and instrumentation amplifiers.
For engineers reviewing the OP90GSZ-REEL datasheet, OP90GSZ-REEL pinout, OP90GSZ-REEL application, or OP90GSZ-REEL equivalent, this page delivers verified specifications, validated pin functions, real-world use cases including zero-in/zero-out signal conditioning, and confirmed alternative options for low-power precision analog design.
Technical Context
The OP90GSZ-REEL uses a PNP input stage with series protection resistors enabling ±20 V input overvoltage tolerance beyond rails. Its output stage provides active pull-down to ~0.8 V above ground, requiring ≤1 MΩ load to reach true 0 V in single-supply mode.
Offset nulling is supported via dedicated pins (Pin 1 and Pin 8), allowing up to 6 mV adjustment range; adding a 100 kΩ resistor in series with the potentiometer reduces resolution to 400 µV for high-precision trimming without affecting temperature drift performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6 V to 36 V single supply or ±0.8 V to ±18 V dual supply - enables direct interface with lithium cells and industrial rails without level-shifting. |
| Input Offset Voltage | 150 µV max at 25°C - eliminates need for external nulling in precision DC-coupled sensor interfaces. |
| Quiescent Supply Current | 20 µA max - supports multi-year operation on AA/AAA batteries in remote sensing nodes. |
| Open-Loop Gain | 700 V/mV min - ensures <0.001% gain error at unity gain with 10 kΩ load in stable closed-loop configurations. |
| Input Voltage Range | Includes negative rail (e.g., 0 V to 4 V with 5 V supply) - enables true "zero-in" operation for ground-referenced transducer signals. |
| Output Voltage Swing | 0 V to V+ − 0.8 V (min) with 10 kΩ load - delivers full-scale analog output down to ground in single-supply data acquisition. |
| PSRR | 5.6 µV/V max - minimizes supply ripple-induced offset shift in battery-powered systems with noisy regulators. |
Pinout & Package
OP90GSZ-REEL is housed in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm pitch, 5.00 mm × 4.00 mm body, and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOS NULL | Offset null adjust terminal - connects to wiper of external potentiometer for fine-tuning input offset voltage. |
| 2 | –IN | Inverting input - accepts differential or single-ended signals; protected by internal series resistors against ±20 V overvoltage. |
| 3 | +IN | Noninverting input - same protection as Pin 2; enables ground-referenced input in single-supply mode. |
| 4 | V– | Negative supply rail - must be connected to ground (single supply) or negative rail (dual supply); not NC. |
| 5 | NC | No connect - internally unconnected; must remain floating per datasheet. |
| 6 | OUT | Amplifier output - drives loads ≥2 kΩ; delivers 5 mA min output current with rail-to-rail swing capability. |
| 7 | V+ | Positive supply rail - accepts 1.6 V to 36 V; PSRR of 5.6 µV/V ensures stable DC accuracy under supply variation. |
| 8 | VOS NULL | Second offset null terminal - completes nulling circuit with Pin 1; unused in non-nulling applications. |
Key Features
| Feature | Design Value |
|---|---|
| True single-supply operation | Input and output voltage ranges include ground - enables direct interfacing with 0–5 V sensors and ADCs without level-shifting circuitry. |
| Ultra-low quiescent current | 20 µA max across –40°C to +85°C - extends battery life in portable instruments and satellite telemetry nodes. |
| High open-loop gain | 700 V/mV min - maintains <0.002% linearity error in 100× gain instrumentation amplifier configurations. |
| Input overvoltage protection | ±20 V beyond supply rails - eliminates need for external clamping diodes in industrial field I/O modules. |
| On-chip offset nulling | Dedicated Pins 1 and 8 support 6 mV trim range - allows calibration of system-level offset without modifying PCB layout. |
Applications
| Battery-Powered Voltage Reference | Single-Supply Current Monitor |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision micropower op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LTC1050CS8#PBF | Zero-drift auto-zero architecture; 0.5 µV max VOS, 1.2 µV/°C TCVOS vs. OP90GSZ-REEL's 150 µV VOS and 2.5 µV/°C drift. | Superior DC precision but higher 120 µA ISY - unsuitable for multi-year battery life targets. | Select when ultra-low drift dominates power budget; avoid where <25 µA supply current is mandatory. |
| MAX4038ASA+ | Rail-to-rail input/output; 100 µV VOS, 12 µA ISY, but limited 3.6 V max supply - no 36 V operation. | Optimized for 1.8–3.6 V logic-compatible systems; cannot replace OP90GSZ-REEL in 5–36 V industrial sensors. | Choose for low-voltage portable electronics; reject for wide-supply or high-voltage sensor front-ends. |
Compared with LTC1050CS8#PBF and MAX4038ASA+, the OP90GSZ-REEL uniquely balances sub-20 µA quiescent current, 36 V supply capability, and ground-sensing input/output - making it irreplaceable in long-life, wide-input-range analog signal chains where zero-drift isn't required.

FAQ
What is the operating temperature range for OP90GSZ-REEL?
The OP90GSZ-REEL is rated for –40°C to +85°C operation, matching the OP90G grade specification. This range is validated across all key parameters including input offset voltage (180–675 µV), supply current (12–30 µA), and open-loop gain (300–600 V/mV), ensuring reliable performance in industrial and outdoor embedded environments.
Does OP90GSZ-REEL support true rail-to-rail output?
The OP90GSZ-REEL provides output swing to within 0.8 V of ground and to within 1.5 V of V+ under 10 kΩ load, meeting "rail-to-rail output" definition for single-supply applications where ground is the lower rail. It does not swing fully to V+ or V–, but its 0 V to V+ − 0.8 V range enables true zero-out operation critical for sensor interfaces.
Can OP90GSZ-REEL be used with a single 1.8 V supply?
Yes - the OP90GSZ-REEL operates down to 1.6 V single supply, so 1.8 V is fully supported. At this voltage, typical supply current is ~15 µA and open-loop gain remains >100 V/mV with RL = 100 kΩ, enabling functional operation in ultra-low-voltage IoT edge nodes powered by coin cells or energy harvesters.
What is the function of Pin 5 on OP90GSZ-REEL?
Pin 5 on OP90GSZ-REEL is labeled NC (No Connect) in the official datasheet and is internally unconnected. It must remain unconnected on the PCB; routing traces or applying voltage to Pin 5 may compromise device reliability or violate JEDEC-compliant SOIC_N mechanical integrity.
How does OP90GSZ-REEL handle input overvoltage conditions?
The OP90GSZ-REEL incorporates PNP input transistors with series protection resistors, allowing inputs to safely withstand voltages up to ±20 V beyond either supply rail without damage. This eliminates external clamping components in field I/O circuits exposed to ESD or inductive kickback, preserving signal integrity in harsh industrial settings.
