AD7399BRU

AD7399BRU Description

The AD7399BRU is a 10-bit voltage output digital-to-analog converter (DAC) designed by Analog Devices Inc., a leading manufacturer in the electronics industry. This IC is housed in a 16-lead TSSOP package and is intended for surface-mount applications. The AD7399BRU features four D/A converters, each capable of providing precise analog output voltages based on digital input data. It operates with a digital supply voltage range of 2.7V to 5.5V and an analog supply voltage range of 2.7V to 5.5V or ±5V, making it versatile for various power supply configurations.

The AD7399BRU communicates with the host system via an SPI data interface, ensuring fast and reliable data transfer. It achieves a maximum INL (Integral Non-Linearity) and DNL (Differential Non-Linearity) of ±1 LSB, which translates to high accuracy and linearity in its analog output. The settling time of 6µs (typical) ensures rapid response to input changes, making it suitable for dynamic applications. The device requires an external reference for its operation, providing flexibility in reference voltage selection.
