LTC2756BCG#PBF

LTC2756 is a 18-bit multiplying serial-input, current-output digital-to-analogue converter. This SoftSpan™ DAC operates from a single 3V to 5V supply and offers six output ranges (upto ±10V) that can be programmed through the 3-wire SPI serial interface or pin-strapped for operation in a single range. Any on-chip register (including DAC output-range settings) 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 output to 0V regardless of output range. It is widely used in application such as instrumentation, medical devices, automatic test equipment, process control and industrial automation etc.
