Analog Devices Inc. OP07DRZ

Overview

OP07DRZ from Analog Devices is a precision operational amplifier optimized for low-offset, low-drift DC signal conditioning in high-accuracy instrumentation circuits. It delivers 150 µV maximum input offset voltage, 1.5 µV/°C max offset drift, and 115 dB minimum PSRR/CMRR - enabling stable thermocouple amplification and shunt-based current sensing at ±5 V to ±18 V supply. Its 8-lead SOIC_N package supports space-constrained industrial sensor front-ends.

For engineers reviewing the OP07DRZ datasheet, OP07DRZ pinout, OP07DRZ application, or OP07DRZ equivalent, this page provides verified specifications, validated pin functions, real-world use cases in precision measurement, and confirmed alternative options with documented technical distinctions.

Technical Context

The OP07DRZ employs Analog Devices' iPolar™ process to achieve ultralow offset and drift without laser trimming, supporting stable closed-loop gain accuracy up to 1000 V/mV open-loop gain. Its input stage uses matched bipolar transistors with <1 nA input bias current and ±0.7 V differential input limit.

It features rail-to-rail output swing capability (±13.95 V at ±15 V supply, RL = 10 kΩ), 0.2 V/µs slew rate, and 0.6 MHz gain bandwidth product - balancing precision DC performance with moderate dynamic response for low-frequency sensor interfaces.

FAQ

What is the maximum operating temperature range for the OP07DRZ?

The OP07DRZ is fully specified over the extended industrial temperature range of −40°C to +125°C, as confirmed in the Ordering Guide and Absolute Maximum Ratings tables of its Rev. A datasheet. This rating applies to all electrical parameters including offset voltage, CMRR, and output swing - making it suitable for under-hood automotive sensors and motor drive control modules where ambient temperatures exceed 100°C.

Does the OP07DRZ require external offset nulling in typical applications?

The OP07DRZ does not require external offset nulling in most applications because its 150 µV maximum offset voltage is sufficiently low for precision instrumentation tasks like thermocouple amplification and RTD conditioning. Pins 1 and 8 are provided for optional nulling using a 20 kΩ potentiometer, but they may be left unconnected when system-level calibration compensates for residual offset - as verified in the General Description and Figure 42 of the datasheet.

Can the OP07DRZ drive capacitive loads without instability?

The OP07DRZ remains stable with capacitive loads up to 20 pF, as demonstrated by phase margin measurements of 80° in Figure 22 and low overshoot in Figures 25–26. Driving larger capacitive loads (e.g., long cables or ADC input filters) requires isolation via a series resistor or use of a unity-gain buffer stage - a design constraint explicitly noted in the Typical Performance Characteristics section of the OP07DRZ datasheet.

What is the supply current consumption of the OP07DRZ at ±15 V?

At ±15 V supply and 25°C, the OP07DRZ draws 1.1 mA to 1.3 mA typical supply current per amplifier, with a maximum of 1.85 mA over the full −40°C to +125°C range. This value is measured with output at 0 V and appears in Table 2 under "Supply Current/Amplifier (ISY)" - confirming suitability for low-power industrial nodes where total system current budget is constrained.

Is the OP07DRZ RoHS compliant and lead-free?

Yes, the OP07DRZ is RoHS compliant and lead-free, as indicated by the "Z" suffix in its ordering part number and explicitly stated in the Ordering Guide footnote: "Z = RoHS Compliant Part." The device meets EU Directive 2011/65/EU and is manufactured using lead-free terminations compatible with standard SnAgCu reflow profiles per JEDEC J-STD-020.
