LTC1659CS8#PBF

LINEAR TECHNOLOGY  LTC1659CS8#PBF  数模转换器, 12 bit, 串行, 2.7V 至 5.5V, SOIC, 8 引脚

The is a single-supply 12-bit Digital-to-analog Converter DAC includes a rail-to-rail output buffer amplifier and an easy-to-use 3-wire cascadable serial interface. The LTC1659 output swings from 0V to REF. The REF input can be tied to VCC which can range from 2.7 to 5.5V. This allows a rail-to-rail output swing from 0V to VCC. The LTC1659 draws only 250µA from a 5V supply. It is guaranteed ±0.5LSB maximum DNL makes the LTC1659 excel in calibration, control and trim/adjust applications.
