DESCRIPTION

The TLV5619 is a 12-bit voltage output DAC with a

microprocessor and TMS320 compatible parallel

interface. The 12 data bits are double buffered so that

the output can be updated asynchronously using the LDAC pin. During normal operation, the device dissi-

pates 8 mW at a 5-V supply and 4.3 mW at a 3-V

supply. The power consumption can be lowered to 50

nW by setting the DAC to power-down mode.

The output voltage is buffered by a ´2 gain rail-to-rail

amplifier, which features a Class A output stage to improve stability and reduce settling time.
