GENERAL DESCRIPTION
The AD5346/AD5347/AD53481 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 0 V to VREF or 0 V to 2 × VREF.
Input data to the DACs is double-buffered, allowing simultane-
ous update of multiple DACs in a system using the LDAC pin.
An asynchronous CLR input is also provided, which resets the
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 0 V 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.
