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, TSX561and 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 (GBP) 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.
Major features of TSX56 series include an input-offset voltage of 600 µV maximum, an input bias current of just 1 pA, and a typical value of the quiescent current of 240 µA (at 5V). Gain-bandwidth product is 900 kHz.
The TSX56 series are in mass production now, priced from $0.50 depending on the configuration/package, in quantities of 1,000 units. Alternative pricing options for higher quantities are available on request.
