Signal amplifier suits multichannel sensors
Mazet
MTI04C signal amplifier
The ability to convert photo currents to the single-digit nA range makes the MTI04C suitable for even the smallest sensor signals.
The MTI04C signal amplifier has four TIA-based amplifier channels integrated on a naked chip.
It makes it possible to amplify signals for multichannel optical sensors, such as arrays or colour sensors, while requiring little space.
Users can set the trans-impedance of the MTI04C to eight different levels.
The amplifier is programmed via three inputs, with the programming effective for all channels at the same time.
It can be programmed while in operation via microcontrollers.
When various photodiodes are to be switched on, the compensation for the trans-impedance amplifiers can be adjusted digitally in 5 and 80pF steps in accordance with the input capacity of the photodiodes.
The lowest current range is 25nA.
The ability to convert photo currents to the single-digit nA range makes the MTI04C suitable for even the smallest sensor signals.
The integrated power-down mode allows the MTI04CS/CQ to switch to a power-saving operating mode.
If the MTI04C is temporarily not required, the zero-signal current consumption can be reduced to 8uA.
These characteristics open up new applications for the signal amplifier, such as in battery-powered measuring and checking devices.
The amplifier's chip size (die) is approximately 1.8 x 2mm.
It is cut as a series component and die and is available on foil.
