1 / 19 page TLV5638 2.7 V TO 5.5 V LOW POWER DUAL 12-BIT DIGITAL-TO-ANALOG CONVERTER WITH INTERNAL REFERENCE AND POWER DOWN SLAS225A – JUNE 1999 – REVISED JANUARY 2000 1 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 features D Dual 12-Bit Voltage Output DAC D Programmable Internal Reference D Programmable Settling Time: 1 µs in Fast Mode, 3.5 µs in Slow Mode D Compatible With TMS320 and SPI™ Serial Ports D Differential Nonlinearity <0.5 LSB Typ D Monotonic Over Temperature applications D Digital Servo Control Loops D Digital Offset and Gain Adjustment D Industrial Process Control D Machine and Motion Control Devices D Mass Storage Devices description The TLV5638 is a dual 12-bit voltage output DAC with a flexible 3-wire serial interface. The serial interface allows glueless interface to TMS320 and SPI ™, QSPI™, and Microwire™ serial ports. It is programmed with a 16-bit serial string containing 4 control and 12 data bits. The resistor string output voltage is buffered by a x2 gain rail-to-rail output buffer. The buffer features a Class AB output stage to improve stability and reduce settling time. The programmable settling time of the DAC allows the designer to optimize speed vs power dissipation. With its on-chip programmable precision voltage reference, the TLV5638 simplifies overall system design. Because of its ability to source up to 1 mA, the reference can also be used as a system reference. 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 an 8-pin SOIC package to reduce board space in standard commercial, industrial, and automotive temperature ranges. It is also available in JG and FK packages in the military temperature range.
