The A-Drive is designed for industrial process control, automatic test equipment, and data acquisition applications that require many channels of analog signal I/Os. The A-Drive is driven by a V104 and supports up to 22 channels of 12-bit ADC inputs and up to eight channels of 12-bit DAC outputs, including 11 ADC inputs and four DAC outputs (optional) from the V104.

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.

The A-Drive provides regulated power (8.5 - 12V input) and RS-232/RS485 drivers.
