2.5 V to 5.5 V, 500 A, Parallel Interface
Quad Voltage-Output 8-/10-/12-Bit DACs
AD5334/AD5335/AD5336/AD5344*
GENERAL DESCRIPTION
The AD5334/AD5335/AD5336/AD5344 are quad 8-, 10-, and
12-bit DACs. They operate from a 2.5 V to 5.5 V supply con-
suming just 500 µA at 3 V, and feature a power-down mode that
further reduces the current to 80 nA. These devices incorporate
an on-chip output buffer that can drive the output to both sup-
ply rails.
The AD5334/AD5335/AD5336/AD5344 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 on the AD5334 and AD5336 allows the output
range to be set at 0 V to V
Input data to the DACs is double-buffered, allowing simultaneous
update of multiple DACs in a system using the LDAC pin.
On the AD5334, AD5335 and AD5336 an asynchronous CLR
input is also provided. This 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 AD5334/AD5335/AD5336/AD5344 are available in Thin
Shrink Small Outline Packages (TSSOP).
