LINEAR TECHNOLOGY  LTC2654IGN-L12#PBF  数模转换器, 12 bit, 串行, 2.7V 至 5.5V, SSOP, 16 引脚

The is a quad 12-bit rail-to-rail Digital-to-analog Converter DAC with integrated 10ppm/°C maximum reference. The DAC has built-in high performance, rail-to-rail, outputs buffers and is guaranteed monotonic. The LTC2654-L has a full-scale output of 2.5V with the integrated reference and operates from a single 2.7 to 5.5V supply. The DAC can also operate with an external reference, which sets the full-scale output to 2 times the external reference voltage. This DAC communicates via a SPI/MICROWIRE compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2654 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DAC reset to zero-scale. If PORSEL is tied to VCC, the DAC reset to mid-scale.
