AD5791-EP is a 1ppm, 20-bit, ±1 LSB INL, voltage output DAC enhanced product by Analog Devices, suitable for defense and aerospace applications.
The AD5791-EP is a single 20-bit, unbuffered voltage-output DAC designed for high-precision applications. It features a relative accuracy specification of +1 LSB max and operates with a versatile 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and DSP standards at clock rates up to 35 MHz.
The device is available in a compact 20-lead TSSOP package and supports an extended automotive operating temperature range of -55°C to +125°C. Key features include 1 ppm resolution, low noise spectral density, and a power-on reset circuit that ensures the DAC output powers up to 0 V in a known impedance state.
