Description

The AD5320BRTZ is a 12-bit buffered voltage out digital-to-analog converter (DAC) that belongs to the Digital To Analog Converters (DACs) product category. This device operates from a single power supply of 2.7 V to 5.5 V and consumes 115 μA at 3 V making it suitable for micro-power operation. With its on-chip precision output amplifier, it becomes possible to achieve rail-to-rail output swing. This electronic component uses a versatile 3-wire serial interface compatible with standard SPI®, QSPI™, MICROWIRE™ and digital signal processing (DSP) interface standards, with operation clock rates up to 30 MHz.
