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 dissipates 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.
V
DD
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.
