AD5760ACPZ

The AD5760 is a true 16-bit, unbuffered voltage output digital-to-analog converter (DAC) that operates from a bipolar supply of up to 33 V. The AD5760 accepts a positive reference input range of 5 V to VDD - 2.5 V and a negative reference input range of VSS + 2.5 V to 0 V. The AD5760 offers a relative accuracy specification of ±0.5 LSB maximum range, and operation is guaranteed monotonic with a ±0.5 LSB differential nonlinearity (DNL) maximum range specification. The device uses a versatile 3-wire serial interface that operates at clock rates of up to 35 MHz and is compatible with standard serial peripheral interface (SPI), QSPI, MICROWIRE, and DSP interface standards. The device incorporates a power-on reset circuit that ensures that the DAC output powers up to 0 V in a known output impedance state and remains in this state until a valid write to the device takes place. The device provides an output clamp feature that places the output in a defined load state.
