GENERAL DESCRIPTION
The AD5330/AD5331/AD5340/AD53411 are single 8-/10-/12-
bit DACs. They operate from a 2.5 V to 5.5 V supply consuming
just 115 μA at 3 V and feature a power-down mode that further
reduces the current to 80 nA. The devices incorporate an on-chip
output buffer that can drive the output to both supply rails, but
the AD5330, AD5340, and AD5341 allow a choice of buffered
or unbuffered reference input.
The AD5330/AD5331/AD5340/AD5341 have a parallel
interface. CS selects the device and data is loaded into the
input registers on the rising edge of WR.
The GAIN pin 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.
The AD5330/AD5331/AD5340/AD5341 are available in thin
shrink small outline packages (TSSOP).
