The LTC2756BCG#PBF is a 18-bit multiplying serial-input current-output Digital-to-analog Converter (DAC) provides full 18-bit performance - INL and DNL of ±1LSB maximum - over temperature without any adjustments. The 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 output to 0V regardless of output range.
- Glitch impulse 0.4nV-s at 3V, 2nV-s at 5V
- Reference current constant for all codes
- Voltage-controlled offset and gain trims
- Serial interface with read-back of all registers
- Clear and power-on-reset to 0V regardless of output range
