C INTERFACE DIGITAL-TO-ANALOG CONVERTER
Micropower Operation: 500 µA at 3 V VDD
The DAC6573 is a low-power, quad channel, 10-Bit
Fast Update Rate: 188 kSPS
buffered voltage output DAC. Its on-chip precision
output amplifier allows rail-to-rail output swing. The
Power-On Reset to Zero
DAC6573 utilizes an I
2C compatible two wire serial
2.7-V to 5.5-V Analog Power Supply
interface supporting high-speed interface mode with
10-Bit Monotonic
address support of up to sixteen DAC6573s for a total
I
2C™ Interface up to 3.4 Mbps
of 64 channels on the bus.
Data Transmit Capability
The DAC6573 requires an external reference voltage
Rail-to-Rail Operation Output Buffer Amplifier
to set the output range of the DAC. The DAC6573
incorporates a power-on-reset circuit that ensures
Double-Buffered Input Register
that the DAC output powers up at zero volts and
Address Support for up to Sixteen DAC6573s
remains there until a valid write takes place in the
Synchronous Update for up to 64 Channels
device. The DAC6573 contains a power-down fea-
Voltage Translators for all Digital Inputs
ture, accessed via the internal control register, that
reduces the current consumption of the device to 200
Operation From –40

nA at 5 V.
Small 16 Lead TSSOP Package
The low power consumption of this part in normal
operation makes it ideally suited to portable battery
operated equipment. The power consumption is less

power-down mode.
Closed-Loop Servo Control
The DAC6573 is available in a 16-lead TSSOP
