LINEAR TECHNOLOGY  LTC2758BCLX#PBF  数模转换器, 18 bit, 串行, 2.7V 至 5.5V, LQFP, 48 引脚

The is a dual 18-bit multiplying serial-input current-output Digital-to-analog Converter DAC provides full 18-bit performance over temperature without any adjustments. 18-bit monotonicity is guaranteed in all performance grades. This SoftSpan™ DAC operates from a single 3 to 5V supply and offers six output ranges that can be programmed through the 3-wire SPI serial interface or pin-strapped for operation in a single range. Any on-chip register can be read for verification in just one instruction cycle and if you change register content, the altered register will be automatically read back during the next instruction cycle. Voltage-controlled offset and gain adjustments are also provided and the power-on reset circuit and CLR pin both reset the DAC outputs to 0V regardless of output range.
