General Info

There are ten channels of signal conditioning circuits for the ADC inputs on the A-Drive board, including six instrumentation operational amplifiers that provide high input impedance and high gain to low-voltage output sensors such as EKG electrodes, thermocouples, or strain gauges.

The 11 ADC inputs on the V104 are buffered by resistors. A temperature sensor is located next to the screw terminals. A 3 ppm/C, 2.5V reference supports the 12-bit ADCs and DACs. The eight channels of 12-bit DAC can output either voltage or current.

The DAC features power-on reset, 3 us output setting time and 5 V/us slew rate. You may customize analog input and output ranges by setting different gain resistors. The seven solenoid drivers can sink 350 mA at 50V.


Includes 11 ch. 12-bit ADC, analog signal conditioning, temperature sensor, reference power supplies, 7 solenoid drivers, RS-232 drivers. Does not include add-on options or controller.
