AD5326BRU

AD5326BRU Description

The AD5326BRU from Analog Devices Inc. is a 12-bit, quad-channel, voltage-output digital-to-analog converter (DAC) designed for precision applications. Housed in a 16-pin TSSOP package, it features an I2C-compatible interface, enabling easy integration into microcontroller-based systems. The device operates with dual power supplies (2.5V to 5.5V for both analog and digital domains), ensuring compatibility with a wide range of systems. With a settling time of 10µs and ±2 LSB INL / ±0.2 LSB DNL accuracy, it delivers reliable performance for high-resolution signal generation. The external reference input allows flexibility in setting the output range, while its string DAC architecture ensures monotonicity and low glitch energy.
