The device includes 8-channels of high speed, high bandwidth, two quadrant multiplying, 8-bit accurate digital-to-analog converter. It includes an output drive buffer per channel capable of driving a +1mA (typ) to a load. DNL of better than +0.8 LSB is achieved with a channel-to-channel matching of better than 0.5% (typ). Stability, matching, and precision of the DACs are achieved by using EXAR’s thin film technology. Also, excellent...
