2.5 V to 5.5 V, 500 ␮A, Parallel Interface  
Quad Voltage-Output 8-/10-/12-Bit DACs  
a
AD5334/AD5335/AD5336/AD5344*  
FEATURES  
GENERAL DESCRIPTION  
AD5334: Quad 8-Bit DAC in 24-Lead TSSOP  
AD5335: Quad 10-Bit DAC in 24-Lead TSSOP  
AD5336: Quad 10-Bit DAC in 28-Lead TSSOP  
AD5344: Quad 12-Bit DAC in 28-Lead TSSOP  
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  
Low Power Operation: 500 ␮A @ 3 V, 600 ␮A @ 5 V  
Power-Down to 80 nA @ 3 V, 200 nA @ 5 V via PD Pin  
2.5 V to 5.5 V Power Supply  
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.  
Double-Buffered Input Logic  
Guaranteed Monotonic by Design Over All Codes  
Output Range: 0–VREF or 0–2 VREF  
Power-On Reset to Zero Volts  
The GAIN pin on the AD5334 and AD5336 allows the output  
Simultaneous Update of DAC Outputs via LDAC Pin  
Asynchronous CLR Facility  
Low Power Parallel Data Interface  
On-Chip Rail-to-Rail Output Buffer Amplifiers  
Temperature Range: –40؇C to +105؇C  
range to be set at 0 V to VREF or 0 V to 2 × VREF  
.
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.  
APPLICATIONS  
Portable Battery-Powered Instruments  
Digital Gain and Offset Adjustment  
Programmable Voltage and Current Sources  
Programmable Attenuators  
The AD5334/AD5335/AD5336/AD5344 are available in Thin  
Shrink Small Outline Packages (TSSOP).
