Product details
Overview
OP471GSZ-REEL from Analog Devices is a monolithic quad operational amplifier optimized for high-speed, low-noise signal conditioning in precision analog systems. It delivers 8 V/µs slew rate, 6.5 MHz gain bandwidth, ≤11 nV/√Hz input voltage noise at 1 kHz, ≤0.8 mV input offset voltage (max), and 105 dB common-mode rejection - enabling use in instrumentation amplifiers, active filters, and differential line drivers requiring tight channel matching and wide dynamic range.
For engineers reviewing the OP471GSZ-REEL datasheet, OP471GSZ-REEL pinout, OP471GSZ-REEL application, or OP471GSZ-REEL equivalent, key selection criteria include unity-gain stability, 14-pin SOIC (S-suffix) package compatibility, guaranteed military-grade temperature operation (–40°C to +85°C), and verified pinout alignment with industry-standard quad op amps including TL074 and LM148.
Technical Context
The OP471GSZ-REEL integrates four identical high-performance amplifiers on a single die, featuring matched input stages critical for multi-channel gain blocks and low-phase-error topologies. Its architecture employs high collector-current biasing to minimize voltage noise while accepting higher current noise - a deliberate trade-off validated across 0.1 Hz–10 MHz frequency range.
It achieves unity-gain stability without external compensation and maintains ≥125 dB channel separation at DC, supporting applications where crosstalk between adjacent channels must remain below –120 dB. Input protection diodes enable robustness against overvoltage transients but require ≥100 Ω series input resistance during asymmetric power-up sequences.

Use Scenario: Amplifying low-level bridge sensor outputs (e.g., strain gauges, load cells) with 24-bit ADCs in weigh scales and structural monitoring systems. IC Role / Device Role / Timing Role: Quad configuration used as three-op-amp IA core (two matched amps for gain-setting, one for output buffering) with fourth amp for reference voltage conditioning. Use Value: ≤11 nV/√Hz noise and ≤0.8 mV offset ensure <1 µV RMS input-referred noise floor and <0.01% gain error over –40°C to +85°C. | Use Scenario: Driving balanced 600 Ω professional audio lines over 100 m cables in broadcast mixing consoles and studio interfaces. IC Role / Device Role / Timing Role: Two amplifiers configured as complementary inverting/non-inverting drivers; remaining two used for feedback sensing and common-mode control. Use Value: 8 V/µs slew rate supports 30 VPP differential swing at 20 kHz with <0.01% THD+N; ≥125 dB channel separation prevents stereo crosstalk. |
| Quad Programmable Gain Stage | Low-Phase-Error Signal Conditioning |
Use Scenario: Multi-channel data acquisition systems requiring independent digital gain control per channel via microcontroller-driven DACs. IC Role / Device Role / Timing Role: Each OP471GSZ-REEL amplifier pairs with one DAC8408 segment to form a digitally programmable transimpedance stage with 256-step gain resolution. Use Value: Matched amplifier characteristics ensure ≤0.1% gain error variation across all four channels; unity-gain stability allows direct DAC ladder feedback. | Use Scenario: Precision phase-sensitive detection in lock-in amplifiers and impedance analyzers where signal integrity at 100 kHz–1 MHz is critical. IC Role / Device Role / Timing Role: Two amplifiers cascaded in second-order compensated topology (A1 main path, A2 feedback path) to extend usable bandwidth by >10× vs. single-op-amp designs.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher input noise (18 nV/√Hz), lower slew rate (13 V/ms), no guaranteed military temp range | Cost-sensitive general-purpose amplification only; unsuitable for precision low-noise front-ends | Select when budget constraints outweigh noise/speed requirements and industrial temp range suffices |
| OP470GPZ | Lower noise (5 nV/√Hz), slower slew rate (2 V/ms), higher input offset drift (10 µV/°C) | Better for ultra-low-noise DC-coupled sensors; worse for wideband AC signals above 100 kHz | Select when 0.1 Hz–10 Hz noise dominates system error budget and bandwidth ≤50 kHz is acceptable |
Compared with TL074CDR and OP470GPZ, OP471GSZ-REEL uniquely balances low noise, high speed, and guaranteed –40°C to +85°C operation - making it optimal for aerospace-grade data loggers, medical ECG front-ends, and test equipment requiring both precision and bandwidth.

FAQ
What is the maximum capacitive load the OP471GSZ-REEL can drive without instability?
The OP471GSZ-REEL is unity-gain stable and can drive up to 1000 pF directly. For loads exceeding this, Figure 11 in the datasheet recommends adding a 200 pF capacitor (C1) and 50 Ω resistor (R3) in series between the output and load to maintain ≥45° phase margin. This configuration preserves stability while delivering full ±12 V swing into the capacitive load.
Does the OP471GSZ-REEL support single-supply operation?
The OP471GSZ-REEL is specified for dual-supply operation (±4.5 V to ±18 V) and does not support true single-supply rail-to-rail input/output. Its input common-mode range extends to ±11 V with ±15 V supplies, and output swing reaches ±12 V - meaning it cannot operate with input signals near V– or V+ rails in single-supply mode. Use only with split supplies or level-shifted signal paths.
How does the channel separation specification impact multi-channel filter design?
The OP471GSZ-REEL guarantees ≥125 dB channel separation at DC and ≥150 dB at 10 Hz, meaning crosstalk between adjacent amplifiers remains below –125 dB. In active filter banks, this prevents unintended coupling between parallel bandpass sections - preserving stopband attenuation and group delay consistency across all four channels without additional shielding or layout isolation.
Is the OP471GSZ-REEL pin-compatible with the TL074 in SOIC-14 packages?
No - the OP471GSZ-REEL uses a 16-lead SOIC package (S-suffix) with two NC pins (pins 8 and 9), whereas TL074CDR uses 14-lead SOIC. However, the functional pin mapping for the four amplifiers, supplies, and inputs matches the industry-standard 14-pin quad layout. Pin-for-pin replacement requires PCB redesign to accommodate the extra leads and NC terminations.
What is the warm-up time required to achieve specified offset voltage stability?
The OP471GSZ-REEL requires ≥5 minutes of power-on stabilization before achieving its guaranteed ≤0.8 mV input offset voltage. As shown in TPC 6, warm-up drift contributes up to 13 µV/min initially due to die temperature rise; after 5 minutes, offset settles within ±0.1 mV of final value - critical for precision DC measurements and auto-zero calibration routines.
