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.

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.
