+2.7 V to +5.5 V, I2C INTERFACE, VOLTAGE OUTPUT, 12-BIT DIGITAL-TO-ANALOG  
CONVERTER  
FEATURES  
DESCRIPTION  
Micropower Operation: 140 µA @ 5 V  
Power-On Reset to Zero  
The DAC7571 is a low-power, single channel, 12-bit  
buffered voltage output DAC. Its on-chip precision  
output amplifier allows rail-to-rail output swing to be  
achieved. The DAC7571 utilizes an I2C compatible  
two wire serial interface that operates at clock rates  
up to 3.4 Mbps with address support of up to two  
DAC7571s on the same data bus.  
+2.7-V to +5.5 V-Power Supply  
Specified Monotonic by Design  
Settling Time: 10 µs to ±0.003%FS  
I2C™ Interface up to 3.4 Mbps  
On-Chip Output Buffer Amplifier, Rail-to-Rail  
Operation  
Double-Buffered Input Register  
Address Support for up to Two DAC7571s  
Small 6 Lead SOT Package  
The output voltage range of the DAC is set to VDD  
.
The DAC7571 incorporates a power-on-reset circuit  
that ensures that the DAC output powers up at zero  
volts and remains there until a valid write to the  
device takes place. The DAC7571 contains  
a
power-down feature, accessed via the internal control  
register, that reduces the current consumption of the  
device to 50 nA at 5 V.  
Operation From –40°C to 105°C  
APPLICATIONS  
The low power consumption of this part in normal  
operation makes it ideally suited for portable battery  
operated equipment. The power consumption is less  
than 0.7 mW at VDD = 5 V reducing to 1 µW in  
power-down mode.  
Process Control  
Data Acquistion Systems  
Closed-Loop Servo Control  
PC Peripherals  
Portable Instrumentation  
The DAC7571 is available in a 6-lead SOT 23  
package.
