DATA SHEET D 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) • 250µV Attainable Input-Offset Error (270C) • Propagation delay of 375 ns • Internally biased for temperature insensitive operation • No phase inversion • (Two versions of design) 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-passtransistor. The final stage shapes the output using buffers/inverters. 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.
