DAC5571
www.ti.com SLAS405A – DECEMBER 2003 – REVISED AUGUST 2005 +2.7 V to +5.5 V, I2C INTERFACE, VOLTAGE OUTPUT,
8-BIT DIGITAL-TO-ANALOG CONVERTER
FEATURES DESCRIPTION The DAC5571 is a low-power, single-channel, 8-bit
buffered voltage output DAC. Its on-chip precision
output amplifier allows rail-to-rail output swing to be
achieved. The DAC5571 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
DAC5571s on the same data bus. Micropower Operation: 125 ВµA @ 3 V
Fast Update Rate: 188 KSPS
Power-On Reset to Zero
+2.7-V to +5.5-V Power Supply
Specified Monotonic by Design
I2Cв„ў 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 DAC5571s
Small 6 Lead SOT 23 Package
Operation From –40°C to 105°C The output voltage range of the DAC is 0 V to VDD.
The DAC5571 incorporates a power-on-reset circuit
that ensures that the DAC output powers up at zero …
