DESCRIPTION
The DAC6573 is a low-power, quad channel, 10-Bit
buffered voltage output DAC. Its on-chip precision
output amplifier allows rail-to-rail output swing. The
DAC6573 utilizes an I
2
C compatible two wire serial
interface supporting high-speed interface mode with
address support of up to sixteen DAC6573s for a total
of 64 channels on the bus.
The DAC6573 requires an external reference voltage
to set the output range of the DAC. The DAC6573
incorporates a power-on-reset circuit that ensures
that the DAC output powers up at zero volts and
remains there until a valid write takes place in the
device. The DAC6573 contains a power-down fea-
ture, accessed via the internal control register, that
reduces the current consumption of the device to 200
nA at 5 V.
The low power consumption of this part in normal
operation makes it ideally suited to portable battery
operated equipment. The power consumption is less
than 3 mW at V
DD
=5 V reducing to 1 碌W in
power-down mode.
The DAC6573 is available in a 16-lead TSSOP
package.
