Component qualification in accordance with JEDEC and industry
standards to ensure reliable operation over an extended
temperature range. This includes, but is not limited to, Highly
Accelerated Stress Test (HAST) or biased 85/85, temperature
cycle, autoclave or unbiased HAST, electromigration, bond
intermetallic life, and mold compound life. Such qualification
testing should not be viewed as justifying use of this component
beyond specified performance and environmental limits.

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.
