 软件简介 |
The MAX512/MAX513 contain three 8-bit, voltage-output
digital-to-analog converters (DAC A, DAC B, and DAC C).
Output buffer amplifiers for DACs A and B provide voltage
outputs while reducing external component count. The
output buffer for DAC A can source or sink 5mA to within
0.5V of VDD or VSS. The buffer for DAC B can source or
sink 0.5mA to within 0.5V of VDD or VSS. DAC C is
unbuffered, providing a third voltage output with increased
accuracy. The MAX512 operates with a single
+5V ±10% supply, and the MAX513 operates with a
+2.7V to +3.6V supply. Both devices can also operate
with split supplies.
The 3-wire serial interface has a maximum operating frequency
of 5MHz and is compatible with SPI™, QSPI™,
and Microwire™. The serial input shift register is 16 bits
long and consists of 8 bits of DAC input data and 8 bits
for DAC selection and shutdown. DAC registers can be
loaded independently or in parallel at the positive edge
of
–C
—
S –
. A latched logic output is also available for auxiliary
control.
Ultra-low power consumption and small packages
(14-pin DIP/SO) make the MAX512/MAX513 ideal for
portable and battery-powered applications. Supply current
is only 1mA, dropping to less than 1μA in shutdown.
Any of the three DACs can be independently shut down.
In shutdown mode, the DAC's R-2R ladder network is
disconnected from the reference input, minimizing system
power consumption.
