Product details
Overview
OP07DRZ-REEL from Analog Devices is a precision operational amplifier optimized for low-offset, low-drift DC signal conditioning in high-accuracy instrumentation. It delivers 150 µV maximum input offset voltage, 1.5 µV/°C max offset drift, and 115 dB minimum PSRR/CMRR across ±4 V to ±18 V supplies - enabling stable thermocouple amplification, RTD bridge excitation, and shunt-based current sensing at industrial temperatures (−40°C to +125°C).
For engineers reviewing the OP07DRZ-REEL datasheet, OP07DRZ-REEL pinout, OP07DRZ-REEL application, or OP07DRZ-REEL equivalent, this page provides verified specifications, SOIC_N package details, nulling terminal configuration, real-world use cases in sensor front-ends, and validated alternatives for precision op-amp selection.
Technical Context
The OP07DRZ-REEL implements a bipolar-input, internally compensated voltage-feedback architecture with iPolar™ process technology, delivering enhanced CMRR (120–140 dB) and PSRR (110–130 dB) versus legacy OP07 variants. Its open-loop gain exceeds 1000 V/mV over full temperature range, supporting high closed-loop accuracy without external compensation.
It features dual nulling terminals (Pins 1 and 8), enabling precise offset trimming in production calibration; its output swing reaches ±13.9 V (RL = 10 kΩ, VS = ±15 V) and maintains linearity up to 15 mA load - critical for driving ADC reference buffers and active filter stages in medical and industrial systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 150 µV max - enables sub-0.01% error in 10 mV–1 V sensor outputs without trimming |
| Offset Drift | 1.5 µV/°C max - ensures <1 µV total drift over 0–70°C ambient, minimizing thermal calibration burden |
| CMRR / PSRR | 120 dB min (CMRR), 115 dB min (PSRR) - rejects common-mode noise and supply ripple in noisy industrial environments |
| Supply Range | ±4 V to ±18 V - supports single-supply-derived rails and wide-range battery or rail-to-rail compatible designs |
| Output Swing | ±13.9 V (VS = ±15 V, RL = 10 kΩ) - delivers >92% of rail-to-rail swing for improved dynamic range in 16-bit+ data acquisition |
| Input Noise | 0.25 µV p-p (0.1–10 Hz) - preserves signal integrity in low-frequency thermocouple and strain gauge measurements |
| Gain Bandwidth | 0.6 MHz - sufficient for anti-aliasing filters and DC-coupled sensor interfaces up to ~10 kHz bandwidth |
Pinout & Package
OP07DRZ-REEL is housed in an 8-lead narrow SOIC (SOIC_N, R-8) package per JEDEC MS-012-AA, with 1.27 mm lead pitch and 5.00 mm × 4.00 mm body dimensions. Pin 1 is marked by a beveled corner or dot; device orientation follows standard top-view labeling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null Input A | Connects to one end of external 20 kΩ trim potentiometer for manual offset nulling |
| 2 | Inverting Input (−IN) | High-impedance node for feedback network connection in inverting configurations |
| 3 | Noninverting Input (+IN) | High-impedance node for reference or sensor signal input in noninverting configurations |
| 4 | Negative Supply (V−) | Accepts −4 V to −18 V; must be decoupled with ≥0.1 µF ceramic capacitor near pin |
| 5 | No Connect (NC) | Internally unconnected; leave floating or tie to ground only if required by PCB layout rules |
| 6 | Output (OUT) | Capable of sourcing/sinking 15 mA; drives 10 kΩ loads with <10 mV droop at ±13.9 V swing |
| 7 | Positive Supply (V+) | Accepts +4 V to +18 V; requires local 0.1 µF ceramic + 10 µF tantalum decoupling |
| 8 | Null Input B | Connects to other end of same 20 kΩ trim potentiometer used on Pin 1 |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP07EPZ | Same core specs but in 8-lead PDIP (N-8); higher θJA (103°C/W vs. 158°C/W); no RoHS compliance | Suitable for prototyping or through-hole legacy boards; not recommended for automated SMT production | Select OP07EPZ only when DIP footprint is mandatory and thermal derating is acceptable. |
| AD8628ARZ | Zero-drift auto-zero architecture; 1 µV max offset, 0.005 µV/°C drift; 2.7–5.5 V single-supply only | Better drift performance but narrower supply range; unsuitable for ±15 V industrial systems | Choose AD8628ARZ only for battery-powered, single-supply, ultra-low-drift applications below 5.5 V. |
Compared with OP07DRZ-REEL, OP07EPZ offers identical electrical performance in through-hole form but lacks RoHS compliance and thermal efficiency, while AD8628ARZ delivers superior drift cancellation at the cost of supply flexibility and higher quiescent current - making OP07DRZ-REEL optimal for robust, wide-supply, RoHS-compliant industrial instrumentation.

FAQ
What is the maximum operating temperature range for OP07DRZ-REEL?
The OP07DRZ-REEL is fully specified from −40°C to +125°C, meeting extended industrial temperature requirements. All key parameters - including offset voltage (350 µV max), offset drift (1.4 µV/°C max), and PSRR (110 dB min) - are guaranteed across this full range, enabling reliable deployment in engine compartments, factory-floor controllers, and outdoor environmental monitoring systems.
Does OP07DRZ-REEL require external offset nulling in all applications?
OP07DRZ-REEL includes dedicated nulling terminals (Pins 1 and 8) for manual trimming, but it does not require external nulling in many applications. With 150 µV max initial offset and 1.5 µV/°C max drift, systems with <100 µV error budgets may operate without trimming - especially when used in closed-loop configurations where feedback inherently suppresses offset. Nulling is recommended only for open-loop DC gain stages demanding sub-50 µV residual error.
Can OP07DRZ-REEL drive capacitive loads directly?
OP07DRZ-REEL is stable with capacitive loads up to 1 nF when configured with unity gain (G = +1), as confirmed by Figure 25–26 in the datasheet showing <12% overshoot. For loads exceeding 1 nF - such as ADC input capacitors or long PCB traces - a series isolation resistor (typically 10–100 Ω) between OP07DRZ-REEL output and the capacitance is required to maintain phase margin above 60° and prevent oscillation.
What is the supply current consumption of OP07DRZ-REEL at ±15 V?
At ±15 V supply and 25°C, OP07DRZ-REEL draws 1.1–1.3 mA typical supply current per amplifier. Over the full −40°C to +125°C range, consumption rises to 1.85 mA max, as documented in Table 2. This low quiescent current enables use in power-constrained industrial nodes without compromising precision - notably lower than older OP07 variants while delivering improved CMRR and output swing.
Is OP07DRZ-REEL RoHS compliant and lead-free?
Yes, OP07DRZ-REEL is RoHS compliant and lead-free, indicated by the "Z" suffix in its ordering code per Analog Devices' Ordering Guide (Page 14). It uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3), allowing standard reflow profiles without special baking. The SOIC_N package (R-8) contains no lead, cadmium, mercury, hexavalent chromium, PBB, or PBDE.
