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

from –40°C to 85°C.
