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 +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%. Stability, matching, and precision of the DACs is achieved by using EXAR’s thin film technology. Also, excellent channel-to-channel isolation is achieved with EXAR’s BiCMOS process which cannot be achi...
