1. GENERAL DESCRIPTION
The MTI-devices are a family of integrated circuits of programmable gain
transimpedance amplifiers with different numbers of channels (4 or 8).
The MTI-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 3 stages is a special feature.
The adjustment is made by programming two pins and is valid for all channels together.
The device packages are optimized for COB-mounting.
