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.
