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.
