ams AS89000 Transimpedance-Amplifier

ams AS89000 Transimpedance-Amplifier

The AS89000-devices are a family of integrated circuits of programmable gain transimpedance amplifiers with 4 channels per IC (more custom specific, on request). The AS89000-devices are mainly used for signal conditioning of sensors with current outputs. They are especially suitable for connection of photodiodes of array and row sensors. The possibility to adjust the transimpedance in 8 stages is a special feature. The adjustment is made by programming three pins and is valid for all channels together. The device packages (naked chip on request) are RoHS conform and optimized for COB- mounting and SMD.

ams AS89020 Converter with digital output

The AS89020 is a 12-bit, 4-channel, current input Analog-to-Digital Converter (ADC). It combines current-to-voltage (TIA) and analog-to-digital (AD) conversion, so that 4 separate current output devices (e.g. photodiodes) can be directly connected to its inputs and digitized. For each of the 4 inputs the AS89020 provides an input amplifier with a track and hold circuit. The outputs of the track and hold stages are serial converted to 12-bit digital words using an analog-to-digital converter (ADC).
