Sensor Signal Amplifier MTI
PRODUCT INFORMATION
Multi-channel transimpedance amplifier (TIA)
With the MTI series, MAZeT provides a family of multi-channel amplifier ICs (current-to-voltage conversion transimpedance amplifiers) for sensors with current output. These are distinguished, among other things, by a programmable bandwidth and high
amplification.

MTI04 MTI04Bx-BF
The MTI04B series are 4-channel transimpedance amplifiers (TIAs). They are ideal for the connection of small
photodiodes and arrays of up to 20pF input capacitance. The TIAs can be programmed for ampli- fication (for currents from 100nA) and bandwidth (up to 500 KHz) in three stages via the external pads.
