The AD5781BRUZ is a precision 18-bit voltage output digital-to-analog converter (DAC) from Analog Devices. It offers excellent linearity with ±0.5 LSB maximum INL and DNL, and low noise density of 7.5 nV/√Hz. The device features a 1 µs typical settling time and a glitch impulse of 1.4 nV-sec, making it suitable for high-performance applications.
This DAC operates from a wide bipolar supply range up to ±16.5 V (33 V total) and accepts external reference voltages. It includes a 35 MHz Schmitt-triggered SPI-compatible digital interface with 1.8 V compatible logic. The R-2R architecture provides an unbuffered voltage output, requiring careful consideration of load impedance for optimal performance.
The AD5781BRUZ is specified over the industrial temperature range of -40°C to +125°C and is packaged in a 20-lead TSSOP (4.40 mm width) for surface mount assembly. Long-term linearity stability is 0.05 LSB typical, and temperature drift is less than 0.05 ppm/°C, ensuring reliable performance over time.
Typical applications include medical instrumentation, test and measurement equipment, industrial control systems, scientific and aerospace instrumentation, and data acquisition systems. The device is also suitable for digital gain and offset adjustment and power supply control.
The digital supply voltage (IOVCC) is 2.7V to 5.5V, and the analog supply can range up to 33 V (bipolar ±16.5 V).
The AD5781BRUZ is offered in a 20-lead TSSOP package (0.173" width, 4.40 mm).
The operating temperature range is -40°C to +125°C.
The device is listed as RoHS3 Compliant, but this status is unverified and should be confirmed with the manufacturer.
The AD5781BRUZ has 18-bit resolution with ±0.5 LSB maximum INL and DNL.
The typical settling time is 1 µs.
The AD5781BRUZ uses a SPI and DSP compatible digital interface with a maximum clock rate of 35 MHz.
