DAC7811IDGSR – TEXAS INSTRUMENTS

The Texas Instruments DAC7811IDGSR is a 16-bit, voltage-output digital-to-analog converter (DAC) housed in a 16-pin, 4mm x 4mm WSON (wettable flank) package. It operates from a single 2.7V to 5.5V supply voltage, offering a full-scale output voltage range programmable from 0V to VREF. The device features a buffered output with a typical output impedance of 50Ω, enabling direct connection to various loads without significant voltage drops. Its internal reference allows for a simplified design, eliminating the need for external reference components._x000D_

The DAC7811IDGSR boasts a low integral non-linearity (INL) of ±0.5 LSB (least significant bit) and a differential non-linearity (DNL) of ±0.5 LSB, ensuring high accuracy and linearity in output signal generation. Data is transferred via a 16-bit SPI serial interface, offering flexible control and integration into microcontroller-based systems. Common applications include precision waveform generation, industrial process control, and instrumentation where high resolution and accuracy are paramount. Its small form factor and low power consumption make it suitable for space-constrained and battery-powered applications. The device’s inherent precision and ease of use significantly reduce design complexity and improve overall system performance compared to lower-resolution DACs.
