AD5780BCPZ

The AD5780 is a single 18-bit, unbuffered voltage output DAC that operates from a bipolar supply of up to 33 V. The AD5780 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 AD5780 offers a relative accuracy specification of ±1.0 LSB maximum, and operation is guaranteed monotonic with a ±1.0 LSB DNL maximum specification. The part uses a versatile 3-wire serial interface that operates at clock rates of up to 35 MHz and is compatible with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to 0 V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides an output clamp feature that places the output in a defined load state. PRODUCT HIGHLIGHTS
