Servoflo's Linecard

Package: SOP16(n), SSOP20

AM400 is an universal amplifier IC for sensing and signal-conditioning applications. It is suitable for differential or single-ended input voltages and generates both a voltage and a current output signal. Its modular design, integrated voltage and current source and protection functions allow a wide range of industrial applications.

Input: >50mVFS and single ended
Output: 0...5/10V, 0/4...20mA, and output for A/D converter
The most versatile IC anywhere!
