DAC8775IRWFT

DAC8775IRWFT Description

The DAC8775IRWFT from Texas Instruments is a high-precision, 16-bit digital-to-analog converter (DAC) designed for demanding industrial and automation applications. This 4-channel DAC integrates both analog current (4–20mA, 0–20mA, 0–24mA) and voltage (0–5V, 0–10V, ±5V, ±10V) outputs, offering exceptional flexibility in control systems. Housed in a compact 72-pin QFN package, it supports SPI interface for seamless communication with microcontrollers or FPGAs. With an INL/DNL of ±12 LSB and ±1 LSB (max), it ensures high linearity and accuracy. The device operates with dual power supplies (12V–36V analog, 2.7V–5.5V digital), making it suitable for harsh industrial environments.

DAC8775IRWFT Features

• 16-bit resolution with ±12 LSB INL for precision signal generation.
