STMicroelectronics Advances Ultra-Low-Power Linear Design with 1.5V Op-Amps

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 –40 to +125 degrees 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 1.5V to 5.5V simplifies low-power design and extends battery life in battery-powered products.

TSV62x and TSV63x offer 420kHz and 880kHz gain-bandwidth-product, respectively. Low input offset voltage (down to 500 micro-volts maximum) and input bias current (1pA) maintain accuracy with small input signals. The TSV62x and TSV63x families also offer shutdown and non-shutdown versions. All devices have rail-to-rail inputs and outputs to maximize dynamic range, and are housed in tiny packages, including the SC70-5 and SOT23-8, with no shutdown pin, and the SC70-6, SOT23-6, MSO10 for the shutdown versions.
