IDE1180 AMADEUS

16 CSA (prg. ±50, ±100, ±200, ±400 fC), with sample and hold, output for every amplifier

The IDE1180 is an application specific integrated circuit (ASIC), which has been designed for the front-end readout of multi-channel plates (MCPs). The chip has 16 inputs of charge sensitive pre-amplifiers (CSA) and 16 single ended voltage outputs. Each pre-amplifier output is connected to a shaper with 20-ns to 40-ns adjustable shaping time. Optionally all shaper outputs can be sampled and held simultaneously. The chip can be used with negative and positive charges up to 50, 100, 200, 400 fC depending on the programmed gain. The integral non-linearity is better than 1 %. The equivalent noise charge is 900 e without load, and 1000 e at 5 pF input load. The chip requires a single positive supply voltage of 3.3 V. The chip derives all internal biases from one external bias of 100 µA. However, one can also apply bias currents externally, if needed. The total power is 100 mW maximum, depending on the bias settings. The chip allows one to test and measure its gain by injection of an external calibrated charge. All amplifier inputs are protected by diodes against over-voltage and electro-static discharge (ESD).
