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.

5. The differential nonlinearity (DNL) sometimes referred to as differential error, is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code.
6. Zero-scale error is the deviation from zero voltage output when the digital input code is zero (see text).
