high performance needs great design. Coverpage: AS89000 Datasheet Please be patient while we transfer this adapted former MAZeT document to the latest ams design. www.ams.com DATASHEET AS89000 Multi-channel programmable gain transimpedance amplifier QSOP16 Order No.: 305100002 Status: preliminary INTRODUCTION 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. 1 BLOCK DIAGRAM Figure 1: Block diagram C R IIN<1> OPAMP 1 VOUT<1> VREF C R PD IIN<X> OPAMP X VOUT<X> AS89000 Production data information is current as of publication date.
