description

The LTC®2752 is a dual-channel, 16-bit multiplication serial input, current-output digital-to-analog converter. The device operates from a 3V to 5V single-operating supply and guarantees monotonicity over the entire temperature range. Without any adjustments, the LTC2752A provides full 16-bit performance (±1LSB INL and DNL max) over the entire temperature range. The SoftSpanTM DAC offers six output ranges (up to ±10V) that can be set via a three-wire SPI serial interface or pin-lap to operate over one output range. Any on-chip register, 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 offers voltage-controlled offset and gain regulation; Moreover, both the power-on reset circuit and the CLR pin reset the DAC output to 0V, regardless of the output range
