description
LTC®The 2756 is an 18-bit multiply serial-in, current-output digital-to-analog converter. Without any regulation, the LTC2756A provides full 18-bit performance over temperature (±1LSB INL and DNL maximum). All performance levels guarantee 18-bit monotonicity. This SoftSpanTMThe DAC operates from a single 3V to 5V supply and offers six output ranges (up to ±10V) that can be set through a 3-wire SPI serial interface, or it can be pin-tied to operate within one output range.
The contents of any on-chip register, including DAC output range settings, can be read to complete verification in just one instruction cycle; Also, if you change the contents of a register, the changed register will be automatically read back in the next instruction cycle.
In addition, the device provides voltage offset and gain adjustment; Moreover, the power-on reset circuit andCLRThe pins reset the DAC output to 0V, independent of the output range.
