LINEAR TECHNOLOGY  LTC2641IDD-14#PBF  数模转换器, 14 bit, 串行, 2.7V 至 5.5V, DFN, 8 引脚

The is a 14-bit un-buffered voltage-output Digital-to-analog Converter DAC operates from a single 2.7 to 5.5V supply and is guaranteed monotonic over temperature. The LTC2641A-16 provides 16-bit performance over temperature. Un-buffered DAC outputs result in low supply current of 120µA and a low offset error of ±1LSB. It features a reference input range of 2V to VDD. VOUT swings from 0V to VREF. It uses a simple SPI/MICROWIRE compatible 3-wire serial interface which can be operated at clock rates up to 50MHz and can interface directly with optocouplers for applications requiring isolation. A power-on reset circuit clears the LTC2641 DAC output to zero scale when power is initially applied. A logic low on the CLR pin asynchronously clears the DAC to zero scale.
