AD5343BRUZ

AD5343 is a dual DAC. This operates from a 2.5V to 5.5V supply consuming just 230µA at 3V, and feature a power-down pin, PD that further reduces the current to 80nA. Active-low CS selects the device and data is loaded into the input registers on the rising edge of active-low WR. Input data to the DAC is double-buffered, allowing simultaneous update of multiple DACs in a system using the active-low LDAC pin. An asynchronous active-low CLR input is also provided, which resets the contents of the Input Register and the DAC register to all zeros. This device also incorporate a power-on reset circuit that ensures that the DAC output powers on to 0 V and remains there until valid data is written to the device. Typical applications are portable battery-powered instruments, digital gain and offset adjustment, programmable voltage and current sources, programmable attenuators, industrial process control.
