AD5320BRMZ

AD5320 is a single, 12-bit buffered voltage out digital-to-analog converter (DAC). Its on-chip precision output amplifier allows rail-to-rail output swing to be achieved. This device utilizes a versatile 3-wire serial interface that operates at clock rates upto 30MHz and is compatible with standard SPI®, QSPI™, MICROWIRE™ and digital signal processing (DSP) interface standards. The reference for device is derived from the power supply inputs and thus gives the widest dynamic output range. The part incorporates a power-on reset circuit that ensures that the DAC output powers up to zero volts and remains there until a valid write takes place to the device. It is widely used in application such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators etc.
