Overview
The ADA4004-1ARZ is a precision single operational amplifier (op-amp) produced by Analog Devices Inc. It is part of the ADA4004 series, known for its low noise and high precision characteristics. This amplifier is designed using the high-performance iPolar™ process, which enhances its noise performance, power consumption, speed, and stability while minimizing its footprint size.
The ADA4004-1ARZ is particularly notable for its very low voltage noise of 1.8 nV/√Hz and a low 1/f noise corner frequency of 6 Hz. It operates over a wide supply voltage range of ±5 V to ±15 V and is fully specified over a temperature range of -40°C to +125°C.
