description
The TLV5633 is a 12-bit voltage output digital-to-analog converter (DAC) with an 8-bit microcontroller
compatible parallel interface. The 8 LSBs, the 4 MSBs, and 5 control bits are written using three different
addresses. Developed for a wide range of supply voltages, the TL V5633 can be operated from 2.7 V to 5.5 V.
The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer . The buffer features a Class A
(slow mode: AB) output stage to improve stability and reduce settling time. The programmable settling time of
the DAC allows the designer to optimize speed versus power dissipation. With its on-chip programmable
precision voltage reference, the TL V5633 simplifies overall system design. Because of its ability to source up
to 1 mA, the internal reference can also be used as a system reference. The settling time and the reference
voltage can be chosen by a control register.
Implemented with a CMOS process, the device is designed for single supply operation from 2.7 V to 5.5 V. It
is available in 20-pin SOIC and TSSOP packages in standard commercial and industrial temperature ranges.
