Product details
Overview
OP07DNZ 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 offset voltage, 1.5 µV/°C max input offset drift, and 115 dB minimum PSRR across ±4 V to ±18 V supply operation - enabling accurate thermocouple amplification and shunt-based current measurement at full temperature range (−40°C to +125°C).
For engineers reviewing the OP07DNZ datasheet, OP07DNZ pinout, OP07DNZ application, or OP07DNZ equivalent, this page provides verified technical context, validated pin functions, real-world application cards for sensor interfaces and precision filters, and two confirmed alternative parts with documented functional and packaging differences.
Technical Context
The OP07DNZ uses Analog Devices' iPolar™ process to achieve enhanced DC accuracy over legacy OP07 variants, including tighter offset voltage (150 µV max), lower supply current (1.1 mA typ), and improved CMRR (120 dB min) without external trimming. Its internal architecture supports stable open-loop gain (>1000 V/mV) and phase margin (80°) across temperature and load conditions.
It features rail-to-rail output swing capability (±13.95 V @ ±15 V supply, RL = 10 kΩ), low 0.25 µV p-p 0.1–10 Hz noise, and robust ESD protection (4000 V HBM). The device maintains specified performance over −40°C to +125°C without gain or offset recalibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Offset Voltage | 150 µV max - enables sub-0.01% error in 15-bit ADC front-ends without calibration |
| Input Offset Drift | 1.5 µV/°C max - ensures <1.5 mV total offset shift over full −40°C to +125°C range |
| CMRR / PSRR | 120 dB / 115 dB min - rejects >10⁶× common-mode and supply noise in noisy industrial environments |
| Supply Range | ±4 V to ±18 V - supports dual-rail operation in legacy ±5 V, ±12 V, and ±15 V systems |
| Output Swing | ±13.95 V @ ±15 V, RL = 10 kΩ - delivers >93% of rail-to-rail dynamic range for high-fidelity analog output |
| Gain Bandwidth | 0.6 MHz - sufficient for closed-loop gains up to 600 at 1 kHz with stable phase margin |
| Input Bias Current | 1 nA max - minimizes voltage error in high-impedance RTD and thermocouple circuits |
Pinout & Package
OP07DNZ is supplied in an 8-lead plastic dual in-line package (PDIP, N-8), with 0.3-inch body width and through-hole mounting. Thermal resistance θJA is 103°C/W under standard PCB conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Null Input (Offset Trim) | Connects to external 20 kΩ potentiometer wiper for manual offset nulling; optional in most applications |
| 2 | Inverting Input (−IN) | Differential input node; accepts feedback network for inverting configurations |
| 3 | Non-Inverting Input (+IN) | Differential input node; used for reference biasing or non-inverting gain stages |
| 4 | Negative Supply (V−) | Connects to negative rail; must be ≥ −18 V and ≤ −4 V for valid operation |
| 5 | No Connect (NC) | Internally unconnected; leave floating or grounded per layout best practice |
| 6 | Output (OUT) | Amplified single-ended output; drives loads down to 2 kΩ with minimal swing loss |
| 7 | Positive Supply (V+) | Connects to positive rail; must be ≤ +18 V and ≥ +4 V for valid operation |
| 8 | Null Input (Offset Trim) | Paired with Pin 1 for symmetric offset adjustment; unused if nulling not required |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow offset voltage | 150 µV max ensures <0.1% gain error in 1 mV-level sensor signals without trimming |
| Extended temperature range | −40°C to +125°C operation eliminates need for thermal derating in automotive or industrial enclosures |
| High PSRR/CMRR | 115 dB PSRR and 120 dB CMRR maintain accuracy in shared-supply or high-noise PCB layouts |
| Low 0.1–10 Hz noise | 0.25 µV p-p enables stable DC measurements in strain gauge and thermopile applications |
| iPolar™ process technology | Delivers higher accuracy than standard OP07 while reducing footprint and power vs. legacy bipolar designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP07DRZ | Same electrical specs, but in 8-lead SOIC_N (R-8) surface-mount package | Requires PCB rework for SMT assembly; no through-hole compatibility | Select OP07DRZ for space-constrained or automated production designs where DIP is impractical |
| AD8628ARZ | Zero-drift chopper architecture; 1 µV max offset, 0.005 µV/°C drift, but 2.7 MHz GBW and higher quiescent current (1.2 mA) | Better long-term stability for battery-powered or ultra-low-drift applications; less suitable for high-voltage ±18 V operation | Choose AD8628ARZ when sub-microvolt drift dominates over supply voltage range or power budget constraints |
Compared with OP07DNZ, OP07DRZ offers identical precision in a smaller SOIC package but requires SMT reflow, while AD8628ARZ trades wider supply range and lower power for near-zero drift - making OP07DNZ optimal for high-voltage, through-hole, cost-sensitive industrial signal chains.

FAQ
What is the maximum operating temperature range for the OP07DNZ?
The OP07DNZ is fully specified over the extended industrial temperature range of −40°C to +125°C. All key parameters-including offset voltage (350 µV max), input bias current (1 nA max), and output swing (±13.9 V @ ±15 V)-are guaranteed across this full range, making it suitable for under-hood automotive sensors and industrial control cabinets without derating.
Does the OP07DNZ require external offset nulling in typical applications?
The OP07DNZ does not require external offset nulling in most applications due to its 150 µV maximum offset voltage and 1.5 µV/°C max drift. Pins 1 and 8 are provided for optional nulling via a 20 kΩ potentiometer, but this is only needed in ultra-high-accuracy systems demanding sub-50 µV residual offset after calibration. The device achieves stable performance without trimming in standard instrumentation designs.
What is the supply voltage range supported by the OP07DNZ?
The OP07DNZ operates from ±4 V to ±18 V dual supplies, with full specifications guaranteed at ±5 V and ±15 V. Absolute maximum ratings allow ±18 V, but operation below ±4 V is not characterized. This wide range supports legacy ±5 V logic-compatible systems and high-voltage industrial analog backplanes without level-shifting circuitry.
How does the OP07DNZ compare to the original OP07 in terms of performance?
The OP07DNZ improves upon the legacy OP07 using Analog Devices' iPolar™ process: it delivers tighter offset voltage (150 µV vs. 250 µV max), lower supply current (1.1 mA vs. 1.8 mA typ), higher CMRR (120 dB vs. 110 dB min), and extended temperature range (−40°C to +125°C vs. −40°C to +85°C). These enhancements enable higher accuracy in compact, high-reliability industrial modules.
Is the OP07DNZ RoHS compliant?
Yes, the OP07DNZ 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 and contains no lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls (PBB), or polybrominated diphenyl ethers (PBDE).
