DESCRIPTION
The DAC8571 is a small low-power, 16-bit voltage
output DAC with an I²C compatible two-wire serial
interface. Its on-chip precision output amplifier allows
rail-to-rail output swing and settles within 10
microseconds. The DAC8571 architecture is 16-bit
monotonic, and factory trimming typically achieves ±4
mV absolute accuracy at all codes. The DAC8571
requires an external reference voltage to set its
output voltage range.
The low power consumption and small size of this
part make it ideally suited to portable battery
operated equipment. The power consumption is typi-
cally 800 µW at V_DD = 5 V reducing to 1 µW in
power-down mode.
The DAC8571 incorporates a 2-wire I²C interface.
Standard, fast, and high-speed modes of I²C oper-
ation are all supported up to 3.4 MHz serial clock
speeds. Multichannel synchronous data update and
power-down operations are supported through the I²C
bus. DAC8571 is also capable of transmitting the
contents of its serial shift register, a key feature for
I²C system verification.
The DAC8571 is available in an 8-lead MSOP pack-
age and is specified over -40°C to 105°C.
