Analog Devices Inc. OP07CJ8

Overview

OP07CJ8 from Analog Devices is a precision operational amplifier optimized for low-offset, low-drift instrumentation applications. It delivers 150 μV maximum input offset voltage (25°C), 1.8 μV/°C max drift over −40°C to +85°C, and 120 V/mV minimum open-loop gain at ±15 V supply. Used in thermocouple amplifiers, RTD signal conditioning, and shunt current measurement circuits where long-term stability and minimal nulling are critical.

For engineers reviewing the OP07CJ8 datasheet, OP07CJ8 pinout, OP07CJ8 application, or OP07CJ8 equivalent, key selection criteria include guaranteed −40°C to +85°C operation, 2.0 μV/month long-term VOS stability, ±13 V input voltage range, 100 dB min CMRR at ±13 V common-mode, and compatibility with external offset trim via Pins 1 and 8.

Technical Context

The OP07CJ8 employs laser-trimmed thin-film resistors at wafer level to achieve ultralow initial offset and exceptional thermal stability. Its bipolar input stage provides high input impedance (≥120 GΩ common-mode) and low input bias current (±7.0 nA max), enabling accurate DC-coupled measurements with high source impedances.

Internal compensation ensures unity-gain stability without external components, while the wide supply range (±3 V to ±18 V) and robust output swing (±12.6 V into 2 kΩ at full temperature range) support operation in industrial sensor front-ends and precision analog signal chains requiring rail-to-rail compatible performance.

FAQ

What is the maximum operating temperature range for OP07CJ8?

The OP07CJ8 is specified for continuous operation from −40°C to +85°C. This extended temperature grade is validated per Analog Devices' production test flow and documented in the OP07C Electrical Characteristics table on page 4 of Rev. G datasheet. The device maintains all key parameters-including 250 μV max input offset voltage and 100 dB min CMRR-within this full range, making OP07CJ8 suitable for under-hood automotive, outdoor infrastructure, and industrial control applications.

Does OP07CJ8 require external offset nulling in typical applications?

OP07CJ8 does not require external offset nulling in most applications due to its factory laser-trimmed input stage, which guarantees ≤150 μV input offset voltage at 25°C and ≤250 μV across −40°C to +85°C. However, Pins 1 and 8 are provided for optional external trim using a 20 kΩ potentiometer, allowing users to reduce residual offset to <5 μV if required by ultra-high-precision systems such as metrology calibrators or laboratory-grade data acquisition front-ends.

What package type is used for OP07CJ8?

OP07CJ8 uses an 8-lead plastic dual-in-line package (PDIP) conforming to JEDEC MS-001 standard. Its mechanical outline matches the N-8 (P-Suffix) designation in the Analog Devices ordering guide, with 0.300" × 0.400" body dimensions, 0.100" lead pitch, and through-hole mounting. This package provides excellent thermal mass for stable DC performance and is widely supported by legacy PCB assembly processes.

How does OP07CJ8 compare to OP07E-grade devices?

OP07CJ8 is rated for −40°C to +85°C operation, whereas OP07E-grade variants (e.g., OP07EPZ) are limited to 0°C to 70°C. Electrically, OP07CJ8 has higher maximum input offset voltage (250 μV vs. 130 μV), higher offset drift (1.8 μV/°C vs. 1.3 μV/°C), and lower minimum open-loop gain (120 V/mV vs. 180 V/mV). These relaxed limits reflect the broader temperature validation, not inferior design - OP07CJ8 remains the preferred choice for industrial and automotive applications requiring extended thermal coverage.

Can OP07CJ8 drive capacitive loads directly?

OP07CJ8 can drive capacitive loads up to 500 pF while maintaining stable operation and ±10 V output swing, as confirmed in the Applications Information section (page 12) of the Rev. G datasheet. For larger capacitive loads - such as ADC input filters or long cables - a 50 Ω series resistor should be placed between the OP07CJ8 output and the capacitance to isolate the amplifier's output stage and prevent peaking or oscillation. This isolation technique preserves signal integrity without degrading DC accuracy.
