Op-amps run off 1,5 V

24 June 2009 Analogue, Mixed Signal, LSI

STMicroelectronics has unveiled 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 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°C to +125°C, 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 μA for the TSV61x, 29 μA for the TSV62x family and 60 μA 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.

The TSV62x and TSV63x offer 420 kHz and 880 kHz gain-bandwidth-product, respectively. Low input offset voltage (down to 500 μV maximum) and input bias current (1 pA) 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 maximise 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.
