Product details
Overview
OP07DRZ-REEL7 from Analog Devices is a precision operational amplifier optimized for low-offset, low-drift DC-coupled signal conditioning in industrial and medical instrumentation. It delivers 150 µV maximum input offset voltage, 1.5 µV/°C max offset drift, and 115 dB minimum PSRR across ±4 V to ±18 V supply operation - enabling accurate amplification of thermocouple, RTD, and shunt-based current signals without frequent recalibration.
For engineers reviewing the OP07DRZ-REEL7 datasheet, OP07DRZ-REEL7 pinout, OP07DRZ-REEL7 application, or OP07DRZ-REEL7 equivalent, this page provides verified technical context, package-specific pin definitions, real-world use-value mapping, and validated alternative options for high-stability analog front-end design.
Technical Context
The OP07DRZ-REEL7 implements a bipolar-input, internally compensated op amp architecture with iPolar™ process technology, delivering enhanced CMRR (120–140 dB) and PSRR (110–130 dB) over −40°C to +125°C. Its open-loop gain exceeds 1000 V/mV at full temperature range, supporting stable closed-loop gains >100 without external compensation.
It features rail-to-rail output swing capability (±13.9 V on ±15 V supplies, ±3.95 V on ±5 V), 0.2 V/µs slew rate, and 0.6 MHz gain-bandwidth product - balancing precision DC performance with sufficient dynamic response for low-frequency sensor interfaces and precision filters.
Key Specifications

|---|---|
| Offset Voltage | 150 µV max (ensures ≤0.0015% error in 10 V full-scale measurement) |
| Offset Drift | 1.5 µV/°C max (limits thermal-induced error to <0.15 mV over 100°C ambient shift) |
| CMRR | 120 dB min (rejects ≥10⁶× common-mode interference in bridge sensor circuits) |
| PSRR | 115 dB min (maintains accuracy despite ±100 mV supply ripple) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP07CP | Higher offset (250 µV max), wider temp range (0°C to +70°C only), DIP-8 package | Limited to commercial-grade instrumentation; lacks extended temperature rating and SOIC packaging | Select only for cost-sensitive, non-industrial designs where −40°C to +125°C operation is unnecessary |
| AD8628ARZ | Zero-drift architecture, 1 µV max offset, 0.002 µV/°C drift, but lower GBW (2.5 MHz) and higher supply current (1.2 mA) | Better long-term stability for ultra-high-precision metrology; less suitable for wide-bandwidth sensor excitation | Choose when sub-microvolt offset stability over years is critical, and bandwidth requirements remain <100 kHz |
Compared with OP07DRZ-REEL7, OP07CP trades extended temperature capability and surface-mount compatibility for lower cost, while AD8628ARZ offers superior drift performance at the expense of higher power and reduced drive strength - making OP07DRZ-REEL7 optimal for industrial-grade, wide-temperature, low-power precision amplification.

FAQ
What is the maximum operating temperature range for OP07DRZ-REEL7?
The OP07DRZ-REEL7 is fully specified over −40°C to +125°C, meeting extended industrial temperature requirements. This range is confirmed in the Ordering Guide and Absolute Maximum Ratings tables of the official Rev. A datasheet, and applies to all electrical parameters including offset voltage, CMRR, and output swing.
Does OP07DRZ-REEL7 require external offset nulling in typical applications?
OP07DRZ-REEL7 does not require external offset nulling in most applications due to its 150 µV maximum input offset voltage. Pins 1 and 8 are provided for optional trimming using a 20 kΩ potentiometer, but this is only necessary when sub-50 µV residual error is mandated - such as in high-resolution weigh scale or calibration equipment designs.
Is OP07DRZ-REEL7 unity-gain stable?
Yes, OP07DRZ-REEL7 is unity-gain stable, as confirmed by Figure 22 (Open-Loop Gain and Phase vs. Frequency) showing 80° phase margin at 0 dB crossover under ±15 V supply conditions. Its internal compensation ensures stability without external components across all standard closed-loop configurations including G = +1, +10, and +100.
What is the supply current consumption of OP07DRZ-REEL7 at ±5 V?
At ±5 V supply and 25°C, OP07DRZ-REEL7 draws 1.1–1.25 mA typical supply current per amplifier, rising to 1.45 mA maximum over 0°C to +70°C and 1.75 mA over −40°C to +125°C. These values are explicitly listed in Table 1 under "Supply Current/Amplifier" in the Rev. A datasheet.
Can OP07DRZ-REEL7 drive a 2 kΩ load effectively?
Yes, OP07DRZ-REEL7 can drive a 2 kΩ load with ±3.9 V minimum output swing on ±5 V supplies and ±13.75 V on ±15 V supplies, as specified in Table 1 and Table 2 under "Output Voltage Swing." It delivers 15 mA output current, sufficient for standard instrumentation loads without external buffering.
