2.5 V to 5.5 V, 400 μA, Quad Voltage Output,  
8-/10-/12-Bit DACs in 16-Lead TSSOP  
AD5307/AD5317/AD5327  
GENERAꢀ DESCRIPTION  
FEATURES  
AD5307: 4 buffered 8-bit DACs in 16-lead TSSOP  
A version: 1 ꢀSB INꢀ; B version: 0.625 ꢀSB INꢀ  
AD5317: 4 buffered 10-bit DACs in 16-lead TSSOP  
A version: 4 ꢀSB INꢀ; B version: 2.5 ꢀSB INꢀ  
AD5327: 4 buffered 12-bit DACs in 16-lead TSSOP  
A version: 16 ꢀSB INꢀ; B version: 10 ꢀSB INꢀ  
ꢀow power operation: 400 μA @ 3 V, 500 μA @ 5 V  
2.5 V to 5.5 V power supply  
The AD5307/AD5317/AD53271 are quad 8-,10-,12-bit buffered  
voltage-output DACs in 16-lead TSSOP that operate from single  
2.5 V to 5.5 V supplies and consume 400 μA at 3 V. Their on-  
chip output amplifiers allow the outputs to swing rail-to-rail with  
a slew rate of 0.7 V/μs. The AD5307/AD5317/AD5327 utilize  
versatile 3-wire serial interfaces that operate at clock rates up to  
30 MHz; these parts are compatible with standard SPI, QSPI,  
MICROWIRE, and DSP interface standards.  
Guaranteed monotonic by design over all codes  
ꢀDAC  
Power down to 90 nA @ 3 V, 300 nA @ 5 V (  
Double-buffered input logic  
pin)  
The references for the four DACs are derived from two reference  
pins (one per DAC pair). These reference inputs can be configured  
as buffered or unbuffered inputs. Each part incorporates a power-  
on reset circuit, ensuring that the DAC outputs power up to 0 V  
and remain there until a valid write to the device takes place.  
Buffered/unbuffered reference input options  
Output range: 0 V to VREF or 0 V to 2 VREF  
Power-on reset to 0 V  
ꢀDAC  
Simultaneous update of outputs (  
CꢀR  
pin)  
CLR  
Asynchronous clear facility (  
pin)  
There is also an asynchronous active low  
DACs to 0 V. The outputs of all DACs can be updated simul-  
LDAC  
pin that clears all  
ꢀow power, SPI®-, QSPI™-, MICROWIRE™-, and DSP-  
compatible 3-wire serial interface  
SDO daisy-chaining option  
On-chip rail-to-rail output buffer amplifiers  
Temperature range of −40°C to +105°C  
taneously using the asynchronous  
input. Each part  
contains a power-down feature that reduces the current  
consumption of the device to 300 nA @ 5 V (90 nA @ 3 V). The  
parts can also be used in daisy-chaining applications using the  
SDO pin.  
APPꢀICATIONS  
Portable battery-powered instruments  
Digital gain and offset adjustment  
Programmable voltage and current sources  
Programmable attenuators  
All three parts are offered in the same pinout, allowing users to  
select the amount of resolution appropriate for their application  
without redesigning their circuit board.
