4-channel USB DAC

This small bus-powered digital-to-analog converter module designed to drive adaptive optics devices with small number of actuators, such as tip-tilt correctors. Its architecture mostly follows one of DAC40USB module with scaled down number of channels, so programming interface is also very similar. The device provides 4 analog outputs  with resolution of 16bit and settling time of 10us. Analog output range of the can be adjusted between 2.5 and 5.5V  by trimming potentiometer and the jumper. Analog output (IDC 10-pin connector) is typically serves as an input for high-voltage amplifier.
