Voltage Reference - U1 - ADR380ARTZ - The voltage reference is used by the ADC and the DAC to convert voltages to binary numbers and vice versa. Temperature Sensors - U6 & U7 - LM94022BIMG - These sensors are used to measure the temperature of the heat-sink attached to the MOSFET. ...
The amplitude and duration of the current pulses delivered through the electrode are usually programmed through a digital to analog converter (DAC). The current output from the DAC is normally amplified to the desired output current amplitude at the current stimulator. The current amplification is ...
