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.

4. DESCRIPTION OF FUNCTION
The MTI-devices are programmable gain transimpedance amplifiers with different numbers of channels (MTI04 4 channels; MTI08 8 channels). There is one transimpedance amplifier per channel between a current input INX and a voltage output OUTX. Its transimpedance is selectable in 3 stages. This adjustment can be effected by setting of digital inputs SW1 and SW2 and is valid for all channels simultaneously (headline 3.2). The inputs SW1 and SW2 are pulled down with a resistor for a default feedback resistor of 25k. The second input of all transimpedance amplifiers is used for a common supply by a reference voltage necessarily fed in through the pin VREF. All channels are compensated for an external input capacitance of the photo-sensor of typical 20pF. The power supply for the MTI-devices is typical 5V between VDD and GND.
