sated bandgap voltage reference, external reference option,
edge-triggered CMOS input latches and a power-down
“sleep”mode. This converter provides excellentdynamic
CMOS process and delivers a low glitch energy output of 2mA performance making it ideal for applications such as signal
to 20mA.

concern. In addition, the LCC package isolates the IC from the
stresses that may occur on the printed circuit board caused by
variations in temperature.
