The TSV6xx families of precision operational amplifiers from STMicroelectronics are designed for low-power and portable products with power-saving features like 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, according to the company, they serve portable medical equipment, instrumentation, signal-conditioning systems, sensor interfaces, and active filtering.
With high electromagnetic-interference (EMI) rejection allowing use in electrically noisy environments, high electrostatic-discharge (ESD) tolerance, and operation over the extended temperature range of –40°C to 125°C, the TSV6xx op amps also can be used in various types of industrial equipment. Performance choices include single, dual, or quad op-amp configurations. Active current as low as 11 µA for the TSV61x, 29 µA for the TSV62x, and 60 µA for the TSV63x contributes to system power savings, while the 1.5- to 5.5-V supply-voltage range simplifies low-power design and extends battery life.
The TSV62x and TSV63x offer 420- 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 also offer shutdown and non-shutdown versions. All devices have rail-to-rail inputs and outputs to maximize dynamic range and come in tiny packages, including the SC70-5 and SOT23-8 with no shutdown pin and the SC70-6, SOT23-6, and MSO10 for the shutdown versions.
The TSV62x and TSV63x are in full production, with pricing from $0.22 (single), $0.30 (dual), and $0.47 (quad) in quantities of 1000. The TSV61x will be released in the third quarter.
