STMicroelectronics Perfects Advanced Process Technology for New Generation of Sensor Electronics

The new ICs are miniature amplifiers (op-amps) used to condition very small sensor signals. Benefiting from the advanced 16V CMOS manufacturing process, developed in-house, ST’s new op-amps deliver better accuracy than existing devices, with greater long-term stability. Moreover, the process enables tiny die sizes permitting ultra-small surface-mount packages. Extremely low power consumption makes the op-amps ideal for battery or solar-powered equipment.



The new op-amps also have enhanced electro-static discharge protection, up to 4 kV, and can operate from -40°C to 125°C allowing use in harsh industrial or automotive environments. ST will release automotive-qualified versions of these devices in 2013.



The TSX561, TSX562 and TSX564,containing one (single), two (dual) and four (quad) op-amps respectively, operate over a wide supply-voltage range from 3V to 16V, allowing use with a variety of industry-standard supply voltages such as 3V, 5V, 12V or ±5V. The new devices join ST’s broad op-amp portfolio, which give designers many choices of operating voltage, precision characteristics, Gain-Bandwidth Product and power consumption. These include the TSV5 series offering similar performance for 5V operation, and the 10V TS94 series that draws just 1.2 µA for use in low-speed applications up to 10 kHz.

-Input-offset voltage (max): 600 µV
