Product Introduction
The AD5346/AD5347/AD5348 are octal 8-, 10-, and 12-bit DACs, operating from a 2.5 V to 5.5 V supply. These devices incorporate an on-chip output buffer that can drive the output to both supply rails, and also allow a choice of buffered or unbuffered reference input.
The AD5346/AD5347/AD5348 have a parallel interface. CS selects the device and data is loaded into the input registers on the rising edge of WR. A readback feature allows the internal DAC registers to be read back through the digital port.
The GAIN pin on these devices allows the output range to be set at 0V to VREF or 0V to 2×VREF.
Input data to the DACs is double-buffered, allowing simultaneous update of multiple DACs in a system using the LDAC pin.
An asynchronous CLR input is also provided, which resets the CLR contents of the input register and the DAC register to all zeros. These devices also incorporate a power-on reset circuit that ensures that the DAC output powers on to 0V and remains there until valid data is written to the device.
All three parts are pin compatible, which allows users to select the amount of resolution appropriate for their application without redesigning their circuit board.
