Industrial Sensor Amplifier - Overview

Analog Microelectronics offers analog ICs for voltage amplification and signal conditioning. The voltage amplifier product family comprises ICs for differential or single-ended input voltages with adjustable amplification and can be used to realize different single-ended output signals (e.g. 0 ... 5/10 V or 0.5 ... 4.5 V). The amplifier ICs have an internal voltage reference and offer various protection functions (e.g. reverse polarity, short circuit, overvoltage protection). The product ranges AM4x0 and AM4x1 are suitable for the industrial supply voltage range of 6 to 35 V, while the ICs in the AM4x7 range can be used with a supply voltage of 5 V and have ratiometric output voltage.

For example the integrated circuits are used for sensor signal conditioning, factory automation, industrial process control or as an impedance converter.

The ICs are RoHS and Reach compliant and available in different packages or as sawn wafer on blue foil.
