The LTC2752 is a dual 16-bit multiplying serial-input, current-output digital-to-analog converter. It operates from a single 3V to 5V supply and is guaranteed monotonic over temperature. The LTC2752A provides full 16-bit performance (±1LSB INL and DNL, max) over temperature without any adjustments. This SoftSpan™ DAC offers six output ranges (up to ±10V) that can be programmed through the 3-wire SPI serial interface, or pinstrapped 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 outputs to 0V regardless of output range.
Applications
- High Resolution Offset and Gain Adjustment
- Process Control and Industrial Automation
- Automatic Test Equipment
- Data Acquisition Systems
