Leading semiconductors specialist, ST Microelectronics introduces a new generation of sensor electronics developed using advanced process technology to deliver new levels of accuracy, energy efficiency, space savings and rugged performance.

ST’s new generation of ICs uses an advanced manufacturing process that helps save energy, improve accuracy and simplify the design of sensors for applications from automotive electronics to smart buildings and industrial controls.

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. The process also 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 4kV, and can operate from -40ºC to 125ºC allowing use in harsh industrial or automotive environments.

The TSX56 series of ICs consists of TSX561, TSX562 and TSX564, containing one (single), two (dual) and four (quad) op-amps respectively. The new devices join ST’s broad op-amp portfolio, which gives designers many choices of operating voltage, precision characteristics, Gain-Bandwidth Product (GBP) and power consumption.

Key features of TSX56 series of ICs:

  • Operates over a wide supply voltage range from 3V to 16V
  • Enables use with a variety of industry-standard supply voltages such as 3V, 5V, 12V or ±5V
  • Input-offset voltage (max): 600µV
  • Input bias current: 1pA
  • Quiescent current (typical): 240µA (at 5V)
  • Gain-Bandwidth Product (typical): 900 kHz
  • Package options:
    • SOT23-5 (TSX561 single)
    • DFN8 2 x 2mm, MiniSO-8 (TSX562 dual)
    • QFN16 3 x 3mm, TSSOP14 (TSX564 quad)
