DAC7552IRGTR – TEXAS INSTRUMENTS

The Texas Instruments DAC7552IRGTR is a 16-bit, voltage-output digital-to-analog converter (DAC) housed in a 28-pin TSSOP (Thin Shrink Small Outline Package). It features a serial interface compatible with SPI, supporting both 3-wire and 4-wire modes, facilitating easy integration into microcontroller-based systems. Operating from a single 2.7V to 5.5V supply, it provides a ±1 LSB INL (Integral Non-Linearity) and a ±1 LSB DNL (Differential Non-Linearity) ensuring high accuracy. The output voltage range is fully adjustable, spanning 0V to VREF, where VREF can be externally set. Its low power consumption (<5mW at 5V) makes it suitable for battery-powered applications._x000D_ _x000D_ The DAC7552IRGTR boasts a fast settling time, crucial for high-speed applications requiring rapid voltage changes. Common use cases include precision waveform generation, industrial control systems demanding accurate analog outputs, and high-resolution data acquisition systems. Its inherent low noise and high linearity make it advantageous over lower-resolution alternatives where precise analog signal reproduction is paramount. The device's SPI interface simplifies software control and minimizes external component count, enhancing design efficiency. However, designers should consider its limited output current drive capability (requiring an external op-amp for higher current applications).
