AD5644RBRMZ-5REEL7

AD5644R is an on-chip reference. It uses a versatile 3-wire serial interface that operates at clock rates upto 50MHz, and is compatible with standard SPI, QSPI™, MICROWIRE™, and DSP interface standards. The on-chip precision output amplifier enables rail-to-rail output swing. This on chip reference is widely used in application such as process controls, data acquisition systems, portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators etc.
