资 源 简 介
The AD5791 is a single 20-bit, unbuffered voltage-output DAC that operates from a bipolar supply of up to 33V. The AD5791 accepts a posiTIve reference input in the range 4V to VDD – 2.5V and a negaTIve reference input in the range VSS + 2.5 V to 0V. The AD5791 offers a relaTIve accuracy specificaTIon of ±1 LSB max, and operation is guaranteed monotonic with a ±1 LSB DNL max specification.
The part uses a versatile 3-wire serial interface that operates at clock rates up to 50 MHz and that is compatible with standard SPI®, QSPI™, MICROWIRE™, and DSP interface standards. The part incorporates a power-on reset circuit that ensures the DAC output powers up to 0V and in a known output impedance state and remains in this state until a valid write to the device takes place. The part provides a disable feature that places the output in a defined load stateApplications
