description
The TLV5621I is a quadruple 8-bit voltage output
digital-to-analog converter (DAC) with buffered
reference inputs (high impedance). The DAC
produces an output voltage that ranges between
either one or two times the reference voltages and
GND, and the DAC is monotonic. The device is
simple to use since it operates from a single
supply of 2.7 V to 5.5 V. A power-on reset function
is incorporated to provide repeatable start-up
conditions. A global hardware shut-down terminal
and the capability to shut down each individual
DAC with software are provided to minimize
power consumption.
Digital control of the TLV5621I is over a simple 3-wire serial bus that is CMOS compatible and easily interfaced
to all popular microprocessor and microcontroller devices. A TLV5621I 11-bit command word consists of
eight bits of data, two DAC select bits, and a range bit for selection between the times one or times two output
range. The TLV5621I digital inputs feature Schmitt triggers for high noise immunity. The DAC registers are
double buffered which allows a complete set of new values to be written to the device, and then under control
of the HWACT signal, all of the DAC outputs are updated simultaneously.
The 14-terminal small-outline (D) package allows digital control of analog functions in space-critical
applications. The TLV5621I does not require external trimming. The TLV5621I is characterized for operation
