description

LTC^®The 2752 is a dual, 16-bit multiply serial in, current output digital-to-analog converter. The device operates from a single 3V to 5V supply and is guaranteed monotonicity over temperature. Without any regulation, the LTC2752A provides full 16-bit performance over temperature (±1LSB INL and DNL maximum). This SoftSpan^TMThe DAC 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 in one output range.

Any on-chip registers, including the DAC output range setpoint, can be read in just one instruction cycle for verification; And if you change the contents of a register, the changed register will be automatically read back in the next instruction cycle.

The device also provides voltage-controlled offset and gain adjustment; Moreover, the power-on reset circuit andCLRBoth pins reset the DAC output to 0V, independent of the output range
