ST’s advanced CMOS manufacturing process delivers 16V op-amps for sensor electronics

STMicroelectronics has unveiled a new generation of ICs using an advanced manufacturing process that assists 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. Moreover, the process allows tiny die sizes permitting ultra-small surface-mount packages. Very low power consumption makes the op-amps suitable for battery or solar-powered equipment.

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, permitting use with a variety of industry-standard supply voltages such as 3V, 5V, 12V or ±5V.

Features of TSX56 series:
1. Input-offset voltage (max): 600 µV
2. Input bias current: 1 pA
3. Quiescent current (typical): 240 µA (at 5V)
4. Gain-Bandwidth Product (typical): 900 kHz
5. Electro-static discharge protection: up to 4 kV
6. Operating temperature range: -40 Deg C to 125 Deg C
7. Package options:
a. SOT23-5 (TSX561 single)
b. DFN8 2 x 2 mm, MiniSO-8 (TSX562 dual)
c. QFN16 3 x 3 mm, TSSOP14 (TSX564 quad)

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

ST to release automotive-qualified versions of these devices in 2013.
