Product details
Overview
OP97FSZ-REEL7 from Analog Devices is a low-power, high-precision operational amplifier designed for DC-critical signal conditioning in battery-powered and thermally constrained systems. It delivers 25 μV max input offset voltage, 0.6 μV/°C max drift, 600 μA max supply current, and 114 dB min CMRR - enabling precision integrators, DAC output stages, and current monitors operating from ±2.25 V to ±20 V supplies.
For engineers reviewing the OP97FSZ-REEL7 datasheet, OP97FSZ-REEL7 pinout, OP97FSZ-REEL7 application, or OP97FSZ-REEL7 equivalent, this page provides verified specifications, SOIC-8 package mapping, thermal performance data across −40°C to +85°C, and validated alternatives for precision op amp replacement in industrial instrumentation and portable test equipment.
Technical Context
The OP97FSZ-REEL7 implements a bipolar input stage with back-to-back diode input protection (no current-limiting resistors), achieving 100 pA max bias current at 25°C and 250 pA max over −55°C to +125°C. Its open-loop gain exceeds 2000 V/mV at 25°C with 0.4 MHz unity-gain bandwidth and 0.1 V/μs min slew rate under load.
It conforms to the OP07 pinout (Pin 1: null adjust low, Pin 8: null adjust high, Pin 5: overcompensation) and supports external offset trimming via a 5 kΩ–100 kΩ potentiometer. The device operates with rail-to-rail input common-mode range extending to within 1 V of either supply and output swing to within 1 V of rails into 10 kΩ.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | 25 μV max at 25°C - eliminates need for external nulling in most precision DC circuits |
| Offset Voltage Drift | 0.6 μV/°C max - ensures stable baseline in temperature-varying environments like industrial sensors |
| Supply Current | 600 μA max - enables multi-year battery life in portable instruments and handheld meters |
| Common-Mode Rejection | 114 dB min - suppresses interference in high-common-mode applications such as motor current sensing |
| Input Bias Current | 100 pA max at 25°C, 250 pA max over full military temp range - preserves accuracy in high-Z source networks (e.g., pH electrodes, photodiode amps) |
| Supply Voltage Range | ±2.25 V to ±20 V - supports operation from single 5 V rails (±2.5 V) up to ±15 V industrial systems |
| Slew Rate | 0.1 V/μs min - sufficient for <1 kHz precision signal paths including strain gauge and RTD interfaces |
Pinout & Package
OP97FSZ-REEL7 is supplied in an 8-lead SOIC_N (R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch, 5.00 mm × 4.00 mm body, and 1.75 mm max height. Thermal resistance θJA = 158°C/W (PCB mounted).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null Adjust Low | Connects to wiper of external trim pot for offset correction; referenced to V− |
| 2 | Inverting Input (−IN) | High-impedance differential input node; protected by back-to-back diodes |
| 3 | Noninverting Input (+IN) | High-impedance differential input node; same protection as Pin 2 |
| 4 | V− | Negative supply terminal; must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | Overcompensation | External capacitor connection to increase phase margin or reduce GBW above gain = 10 |
| 6 | Output (OUT) | Capacitive-load tolerant output; stable with ≥1000 pF without isolation resistor |
| 7 | V+ | Positive supply terminal; decoupling required adjacent to pin |
| 8 | Null Adjust High | Connects to other end of trim pot; referenced to V+ |
Key Features
| Feature | Design Value |
|---|---|
| Low power precision architecture | 600 μA max supply current at ±15 V - 1/6 that of OP07, enabling thermal-constrained PCB layouts |
| Ultra-low input bias current | 100 pA max at 25°C, maintained below 250 pA from −55°C to +125°C - critical for sample-and-hold and log amplifier stability |
| Extended common-mode range | Input common-mode extends to within 1 V of either rail - supports direct interfacing to transducers with wide output swings |
| Robust capacitive load drive | Stable with 1000 pF output capacitance - eliminates need for isolation resistors in DAC buffer and filter applications |
| OP07 pin-compatible upgrade | Identical 8-pin SOIC footprint and nulling configuration - drop-in replacement without layout change for legacy OP07 designs |
Applications
| Strain Gauge Signal Conditioning | DAC Output Amplification |
|---|---|
|

IC Role / Device Role / Timing Role: High-CMRR difference amplifier configured with matched resistor network to reject bus voltage noise. Use Value: 114 dB min CMRR reduces common-mode error contribution to <0.00025% - dominated only by resistor tolerance mismatch. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP07DPZ-REEL7 | Higher supply current (2.5 mA typ), 10 μV max VOS, no overcompensation pin | Superior initial offset but unsuitable for battery-powered systems due to 4× higher quiescent power | Select when absolute lowest VOS is prioritized over power and thermal constraints |
| AD8628ARZ-REEL7 | Zero-drift architecture, 1 μV max VOS, 1.2 mA supply current, rail-to-rail output | Eliminates 1/f noise and drift but requires higher supply current and lacks OP07 pin compatibility | Select when microvolt-level drift cancellation is mandatory and board redesign is acceptable |
Compared with OP07DPZ-REEL7 and AD8628ARZ-REEL7, OP97FSZ-REEL7 uniquely balances ultra-low power (600 μA), OP07 pin compatibility, and sub-μV/°C drift - making it the optimal choice for upgrading legacy precision analog systems without PCB revision while maintaining thermal headroom.

FAQ
Is OP97FSZ-REEL7 pin-compatible with OP07-based designs?
Yes, OP97FSZ-REEL7 uses the identical 8-pin SOIC footprint and nulling configuration (Pins 1 and 8 for trim pot) as the OP07. No PCB layout changes are required for drop-in replacement, and its lower supply current (600 μA vs. 2.5 mA) reduces thermal load in dense analog sections. The overcompensation pin (Pin 5) adds flexibility not present in OP07 but remains unused in standard configurations.
What is the maximum capacitive load OP97FSZ-REEL7 can drive without instability?
OP97FSZ-REEL7 is stable with output capacitances up to 1000 pF without external isolation resistors, as confirmed by transient response testing in Figure 31 of the Rev. G datasheet. For loads exceeding 1000 pF, connect a small series resistor (e.g., 10–50 Ω) between the output and capacitive node to maintain phase margin, especially in unity-gain configurations.
Does OP97FSZ-REEL7 require external offset nulling in typical applications?
No - OP97FSZ-REEL7's 25 μV maximum input offset voltage at 25°C and 0.6 μV/°C drift typically eliminate the need for external nulling. The datasheet states "external offset trimming is not required in the majority of circuits." Null adjustment (via Pins 1/8) is reserved for applications demanding sub-10 μV baseline accuracy or compensating for system-level drift contributors beyond the op amp itself.
How does OP97FSZ-REEL7 perform at elevated temperatures, such as +125°C?
OP97FSZ-REEL7 is rated for −40°C to +85°C operation. While its electrical characteristics are guaranteed only within that range, the datasheet confirms bias current remains ≤750 pA and offset voltage ≤200 μV at +125°C (Table 2, OP97F grade). However, extended operation beyond +85°C voids warranty and may accelerate parameter drift; for true military-range use, consider the OP97GP variant or alternative qualified devices.
Can OP97FSZ-REEL7 be used with single-supply configurations?
Yes - OP97FSZ-REEL7 operates with total supply voltages as low as ±2.25 V (i.e., 4.5 V), enabling use in single-supply systems with appropriate level-shifting. Its input common-mode range extends to within 1 V of either rail, and output swings to within 1 V of rails into 10 kΩ. For true single-supply 0–5 V operation, bias inputs at mid-rail (2.5 V) and verify output headroom against load requirements.
