Analog Devices OP400 Quad Operational Amplifier Datasheet
The OP400 quad operational amplifier delivers OP77‑type performance in a compact quad package. It features an input offset voltage as low as 150 pV, offset drift of only 1.2 pV/°C, and a supply current of less than 725 pA per amplifier, making it ideal for low‑power, high‑precision applications. The device also offers a high open‑loop gain (minimum 5000 V/mV), low input bias current (3 nA max), and low noise voltage density (11 nV/√Hz at 1 kHz).\n\nThe OP400 is available in several package options, including 14‑lead ceramic DIP, 14‑lead plastic DIP, and 16‑lead SOIC, and is pin‑compatible with LM148, HA4741, RM4156, and LT1014. It operates over a wide temperature range (‑55 °C to +125 °C for the A grade) and can drive capacitive loads up to 10 nF without instability, making it suitable for instrumentation, sensor interfaces, and other precision analog circuits.
