TSM982CUA+ Description

The TSM982CUA+ is a high-performance linear comparator with a voltage reference, designed by Silicon Labs. This IC is part of the TSM98x series and is housed in an 8MSOP package. It features two comparator elements with a typical output current of 40mA. The device operates within a supply voltage range of 2.5V to 11V for single supply and ±1.25V to ±5.5V for dual supply. It is designed for surface mount applications and is suitable for operating temperatures ranging from 0°C to 70°C. The TSM982CUA+ offers a maximum propagation delay of 12µs, ensuring fast response times. It also provides a high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 80dB, minimizing the impact of noise and supply variations on performance. The input offset voltage is a maximum of 10mV at 2.5V, and the input bias current is extremely low at 0.005µA at 2.5V. The quiescent current is also low, at a maximum of 6µA, making it suitable for low-power applications. The device includes a built-in hysteresis of 50mV, which helps in stabilizing the output in noisy environments. The TSM982CUA+ is classified under ECCN EAR99 and HTSUS 8542.39.0001, and it has a moisture sensitivity level (MSL) of 1, indicating unlimited storage conditions.
