IDE1140

64 Channel Sample-and-Hold and Multiplexer Output

Product Description

The IDE1140 (previously VA140) is a 64 channel low-noise/low power high dynamic range charge sensitive preamplifier-shaper circuit, with simultaneous sample and hold, multiplexed analogue readout, calibration facilities and internally generated biases. High integration time.
The pre-amplification stage is optimized for a 50pF detector capacitive load. The ASIC can use an active current compensation by introducing a MOS source/sink at the preamplifier’s input.
The IDE1140 is an updated version of the VA64HDR9A ASIC.
