ams AS89020 Converter with digital output

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.

The AS89010 processes via charge-balance method and converts lowest photocurrents at high accuracy. Its full-scale range can be customized to specific applications. Sensitivity of 20 fA/LSB at a dynamic of 1 to 1,000,000. The IC is temperature compensated and features the possibility of external synchronization.
