Master Board for MAX4940 Standalone Waveform Generator Evaluation Kit

The MAX4940/MAX4940A integrated circuits generate high-voltage, high-frequency, unipolar or bipolar pulses from low-voltage logic inputs. These quad/dual pulsers feature independent logic inputs, independent high-voltage pulser outputs with active clamps and independent high-voltage supply inputs. The MAX4940/MAX4940A feature quad, high-voltage pulsers with 8.5O output impedance for the high-voltage outputs and a 21O impedance for the active clamp. The high-voltage outputs can provide 2.0A (typ) output current. All devices use two logic inputs per channel to control the positive and negative pulses. The MAX4940/MAX4940A have a dedicated input to control the active clamp. All devices feature an independent enable input EN. All digital inputs are CMOS compatible. The MAX4940/MAX4940A are available in a 56-pin, 8mm x 8mm, TQFN exposed pad package and are specified over the 0°C to +70°C commercial temperature range. Warning: Exercise caution. The MAX4940/MAX4940A are designed to operate with high voltages.
