AD5302BRMZ-REEL7

AD5302BRMZ-REEL7 is a dual channel, 8bit buffered voltage output DAC. 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 DSP interface standards. The reference for the DAC is derived from two reference pins (one per DAC). The reference inputs can be configured as buffered or unbuffered inputs. The output of DAC can be updated simultaneously using the asynchronous active-low LDAC input. The part incorporates a power-on reset circuit, which ensures that the DAC outputs power-up to 0V and remains there until a valid write takes place to the device. It is used in applications such as portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, and programmable attenuators.
