LND5432HT

Temperature-Insensitive Comparator with Rail-to-Rail

Input/output with Extended Temperature Range

GENERAL DESCRIPTION

FEATURES

The LND5432HT is a high-gain differential amplifier

with rail-to-rail input voltage performance

range, designed in 0.5µm SOI technology.

•

Rail-to-Rail input/output performance

range

•

2.85mV Input-Offset Error

(Temperature-Insensitive)

The LND5432HT uses a 3.3V supply, and provides

rise and fall times of less than 75ns at the output.

•

250µV Attainable Input-Offset Error

(27⁰C)

•

Propagation delay of 375 ns

Internally biased for temperature

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.

insensitive operation

•

No phase inversion

(Two versions of design)

At 27⁰C, 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 27⁰C to 200⁰C the input-offset

error is 2.85mV for both variations.

APPLICATIONS

•

Null and Zero-Crossing Detector

Temperature Insensitive High-Gain Op-

Amp.

•

10-Bit(or less) resolution ADC-

Comparator for 27⁰C to 200⁰C

13-Bit(or less) resolution ADC-

Comparator at 27⁰C
