Overview
The ADA4004-1ARZ-R7 is a precision operational amplifier produced by Analog Devices Inc. This device is part of the ADA4004 series, which includes the ADA4004-1, ADA4004-2, and ADA4004-4. The ADA4004-1 is designed on the high-performance iPolar™ process, which enhances its performance by reducing noise and power consumption, increasing speed and stability, and minimizing footprint size. It is particularly noted for its low voltage noise density of 1.8 nV/√Hz and a low 6 Hz 1/f noise corner frequency, making it suitable for high-precision applications.
