AD5334BRUZ

AD5334 is a quad channel, 8-bit DAC. They operate from a 2.5V to 5.5V supply consuming just 500µA at 3V, and feature a power-down mode that further reduces the current to 80nA. This device incorporate an on-chip output buffer that can drive the output to both supply rails. The device has a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR. Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin. It is widely used in application portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators, industrial process control etc.
