Related Devices Part No. Description AD5791 20-bit, 1 ppm accurate DAC AD5541A/AD5542A 16-bit, 1 LSB accurate 5 V DAC GENERAL DESCRIPTION The AD57811 is a single 18-bit, unbuffered voltage output DAC that operates from a bipolar supply of up to 33 V. The AD5781 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 AD5781 offers a relative accuracy specification of ±0.5 LSB maximum, and operation is guaranteed monotonic with a ±0.5 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 1. True 18-Bit Accuracy. 2. Wide Power Supply Range of Up to ±16.5 V. 3. −40°C to +125°C Operating Temperature Range. 4. Low 7.5 nV/√Hz Noise. 5. Low 0.05 ppm/°C Temperature Drift. 1 Protected by U.S. Patent No 7884747, and other patents are pending. |
