LND5432HT
Temperature-Insensitive Comparator with Rail-to-Rail
Input/output with Extended Temperature Range
GENERAL DESCRIPTION
The LND5432HT is a high-gain differential amplifier
with rail-to-rail input voltage performance
range, designed in 0.5µm SOI technology.
The LND5432HT uses a 3.3V supply, and provides
rise and fall times of less than 75ns at the output.
The LND5432HT uses a two sided folded cascode
primary differential stage to create a rail-to-rail input
range. The intermediate stage has two variations, a
differential amplifier or a logic controlled dual-pass-
transistor. The final stage shapes the output using
buffers/inverters.
At 27
0
C, over the 0.0V-3.3V common mode input
voltage range the input-offset error is less than 1mV
and 250µV for the differential amplifier and logic
controlled variations respectively. Over the
temperature range of 27
0
C to 200
0
C the input-offset
error is 2.85mV for both variations.
