일반 설명

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.
