STMicroelectronics introduces three new families of precision op-amps targeting low-power and portable products, with power-saving features that include high-speed performance at low supply current, operation from a 1.5 V supply, and device-shutdown capability. Offering low power consumption, high bandwidth and good accuracy, the TSV6xx families serve applications such as portable medical equipment, instrumentation, signal-conditioning systems, sensor interfaces, and active filtering. With high EMI rejection, allowing use in electrically noisy environments, high ESD tolerance, and operation over the extended temperature range from 40º to +125º centigrade, the new op-amps can also be used in various types of industrial equipment. The TSV61x, TSV62x and TSV63x families offer a variety of performance choices in single, dual or quad op-amp configurations. Active current as low as 11-microamps for the TSV61x, 29-microamps for the TSV62x family and 60-microamps for the TSV63x family contributes to system power savings, while the supply-voltage range of 1.5 V to 5.5 V simplifies low-power design and extends battery life in battery-powered products.
