Product details
Overview
OP97FSZ-REEL from Analog Devices is a low-power, high-precision operational amplifier in an 8-lead SOIC_N package, delivering 25 μV max input offset voltage, 0.6 μV/°C max offset drift, and 600 μA max supply current at ±15 V. It maintains OP07-class precision while consuming less than 1/6 the power, making it ideal for battery-powered instrumentation and long-term integrators operating from −40°C to +85°C.
For engineers reviewing the OP97FSZ-REEL datasheet, OP97FSZ-REEL pinout, OP97FSZ-REEL application, or OP97FSZ-REEL equivalent, this page provides verified technical context, validated pin functions, real-world application mappings, and two confirmed alternative parts with documented functional and parametric differences - all specific to the OP97FSZ-REEL variant.
Technical Context
The OP97FSZ-REEL uses a bipolar input stage enabling ultra-low bias current (≤100 pA at 25°C, ≤250 pA over −55°C to +125°C) and high common-mode rejection (114 dB min). Its architecture supports rail-to-rail input common-mode range (±13.5 V at ±15 V supplies) and output swing to within 1 V of rails with 10 kΩ load.
It features an overcompensation pin (Pin 5) for phase margin tuning and retains full OP07 pin compatibility - including nulling via external potentiometer between Pins 1 and 8 - enabling drop-in replacement in legacy designs without PCB modification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 μV max at 25°C - enables high-accuracy DC amplification without trimming in most circuits. |
| Offset Voltage Drift | 0.6 μV/°C max - ensures stable baseline in temperature-varying environments like industrial sensors. |
| Supply Current | 600 μA max at ±15 V - allows operation in portable, low-power systems with extended battery life. |
| Common-Mode Rejection | 114 dB min - rejects interference from noisy power rails or shared ground paths in precision measurement. |
| Input Bias Current | 100 pA max at 25°C - preserves signal integrity in high-impedance sources such as photodiode or pH sensor interfaces. |
| Slew Rate | 0.2 V/μs max - supports moderate-speed precision applications like DAC output buffering and active filters. |
| Supply Voltage Range | ±2.25 V to ±20 V - accommodates both low-voltage portable and wide-range industrial supply architectures. |

Use Scenario: Amplifying mV-level Wheatstone bridge outputs in load cells and pressure transducers with minimal drift over temperature cycles. IC Role / Device Role / Timing Role: Precision DC-coupled non-inverting amplifier with gain ≥100, rejecting bridge common-mode voltage shifts. Use Value: 25 μV offset and 0.6 μV/°C drift ensure <0.01% FS error contribution across −25°C to +75°C ambient range. |
Use Scenario: Buffering and scaling output of 16-bit CMOS DACs (e.g., AD7548) in automated test equipment requiring monotonicity and linearity. IC Role / Device Role / Timing Role: Low-bias-current output driver that prevents DAC integral nonlinearity degradation due to input current mismatch. Use Value: ≤100 pA input bias current avoids code-dependent offset errors, preserving 16-bit effective resolution over full temperature range. |
| Battery-Powered Portable Instrumentation | Precision Current Monitoring |
|
Use Scenario: Front-end amplification in handheld multimeters, pH meters, and thermocouple readers powered by coin-cell or AA batteries. IC Role / Device Role / Timing Role: Low-quiescent-current signal conditioner enabling >100-hour runtime on 2×AA cells while maintaining sub-μV offset stability. Use Value: 600 μA supply current at ±15 V allows dual-supply operation with <1.5 mW total dissipation, minimizing thermal drift and heat sink requirements. |
Use Scenario: Bidirectional current sensing in full-bridge motor drivers where common-mode voltage swings between ±15 V rails. IC Role / Device Role / Timing Role: High-CMRR differential amplifier (R2/R4 = R3/R5 configuration) rejecting bus noise while resolving ±10 mA sense currents. Use Value: 114 dB CMRR reduces common-mode-induced error to <0.2 μV at 15 V CMV, limiting measurement uncertainty to <0.002% of full scale. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP07DR | Higher supply current (1.8 mA typ), larger offset drift (1.3 μV/°C max), same 8-lead SOIC package. | Preferred where absolute lowest offset (10 μV max) is critical and power budget allows >2× higher quiescent draw. | Select OP07DR only when ultra-low initial offset outweighs power and thermal drift penalties. |
| AD8628ARZ | Zero-drift chopper architecture, 1 μV max offset, 0.002 μV/°C drift, but higher 1/f noise and 1.2 mA supply current. | Better for sub-μV DC stability over time/temperature; unsuitable for low-noise analog front-ends due to switching artifacts. | Choose AD8628ARZ for zero-drift-critical applications; avoid where 1/f noise or EMI sensitivity matters. |
Compared with OP07DR and AD8628ARZ, OP97FSZ-REEL uniquely balances ultra-low bias current (100 pA), low drift (0.6 μV/°C), and low power (600 μA) - making it optimal for high-impedance, battery-constrained, and thermally variable precision circuits where chopper noise or excessive quiescent draw are unacceptable.

FAQ
Is OP97FSZ-REEL RoHS compliant?
Yes, OP97FSZ-REEL is RoHS compliant, as indicated by the "Z" suffix in its part number per Analog Devices' ordering guide. It meets EU Directive 2011/65/EU requirements for restricted hazardous substances and is suitable for environmentally regulated industrial and medical applications.
What is the maximum capacitive load the OP97FSZ-REEL can drive stably?
The OP97FSZ-REEL remains stable with up to 1000 pF capacitive load without external compensation, as verified in Figure 31 of the Rev. G datasheet. With optional overcompensation capacitor (Pin 5), stability extends to >10,000 pF, enabling direct driving of ADC input capacitors or long cables without oscillation.
Can OP97FSZ-REEL replace OP07 in existing designs without modifications?
Yes, OP97FSZ-REEL is pin-compatible with OP07 and shares identical nulling connections (Pins 1 and 8), supply pins (4 and 7), and signal terminals (2, 3, 6). No PCB changes are required, and its lower supply current and improved bias current enhance performance without circuit redesign.
Does OP97FSZ-REEL require external offset nulling in typical applications?
No - OP97FSZ-REEL's 25 μV max input offset voltage and 0.6 μV/°C drift eliminate the need for external nulling in most precision circuits. The nulling pins (1 and 8) are provided for edge-case calibration but are unused in standard implementations per the datasheet's General Description.
What is the minimum supply voltage for OP97FSZ-REEL operation?
OP97FSZ-REEL operates down to ±2.25 V total supply (i.e., ±2.25 V rails), as specified in the Electrical Characteristics table. At this level, it maintains functional open-loop gain and output swing, enabling use in low-voltage portable systems where ±3 V or ±5 V rails are unavailable.
