STMicroelectronics has introduced a high-precision op amp dubbed the TS507 that features an ultralow input offset voltage guaranteed over a wide common-mode voltage range, making it suitable for automotive and industrial applications.

An ST patented trimming technique adjusts the input offset voltage of the TS507 at 100?V maximum. This digital method is done after packaging and has the advantage of reducing the device's overall cost by avoiding the use of external components.

The TS507 also offers a good precision over the full temperature range through a low input offset voltage drift (250?V maximum over the range of 0 to 85C). The TS507 also features key electrical characteristics such as a high open-loop gain (131dB typical at 5V) and a high CMRR (115dB typical at 5V).

Other major benefits of the TS507 include low noise and a very high output current (up to 120mA in a short-circuit configuration). Internal ESD protection is also extended to 5kV, for the human body model, to minimize handling and fabrication risks.

Part numbers TS507ID-TS507IDT (industrial range of -40C to 125C) and TS507CD-TS507CDT (commercial range of 0 to 85C) are available in a SO8 ECOPACK package and cost 60 cents and 50 cents, respectively in quantities of 1,000 pieces. Part numbers TS507ILT and TS507CLT come in the space-saving SOT23-5 ECOPACK package and cost 60 cents and 50 cents, respectively.

The device is currently in production.
