ST Microelectronics unveils 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 16 V 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. 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 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 3 V to 16 V, allowing use with a variety of industry-standard supply voltages such as 3 V, 5 V, 12 V or ±5 V. The new devices join ST’s broad op-amp portfolio, which give designers many choices of operating voltage, precision characteristics, Gain-Bandwidth Product (GBP) and power consumption. These include the TSV5 series offering similar performance for 5 V operation, and the 10V TS94 series that draws 1.2 µA for use in low-speed applications up to 10 kHz.

Package options include: SOT23-5 (TSX561 single); DFN8 2 x 2mm, MiniSO-8 (TSX562 dual) and QFN16 3 x 3mm, TSSOP14 (TSX564 quad)

Availability and Pricing

The TSX56 series are in mass production now, priced from $0.50 depending on the configuration/package, in quantities of 1,000 units.
