Better accuracy at less power consumption and more design
simplicity, this is what STMicroelectronics promises customers of its
new 16V operational amplifiers. The secret behind the improvements is a
new manufacturing process for these semiconductors. The products address
the needs of automotive electronics as well as smart buildings or
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.
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.
