LTC1446L

The LTC1446 and LTC1446L are the first dual, single supply, rail-to-rail voltage output 12-bit DACs. Both parts include an internal reference and two DACs with rail-to-rail output buffer amplifiers, packaged into a space-saving 8-pin SO or PDIP package. The LTC1446’s patented architecture is inherently monotonic and has excellent 12-bit DNL, guaranteed to be less than 0.5LSB. These parts have an easy-to-use SPI compatible interface that allows daisy-chaining. ...
