The device includes 4-channels of high speed, wide bandwidth, two quadrant multiplying, 8-bit accurate digital-toanalog converter. It includes an output drive buffer per channel capable of driving a +1mA (typ) load. DNL of better than +0.5 LSB is achieved with a channel-to-channel matching of typically 0.5%. Stability, matching, and precision of the DACs are achieved by using MPS’...
