OPA4992-Q1, New Op Amp Launched by Texas Instruments
As an innovative manufacturer, Texas Instruments design, manufacture, test, and sell analog and embedded semiconductors globally, aiming to helping customers overcome barriers and solve problems. It designed and developed a new low-offset-voltage low-noise op amp, now it is sellable on TI web.
An operational amplifier is an integrated circuit that can amplify weak electric signals. An operational amplifier has two input pins and one output pin. Its basic role is to amplify and output the voltage difference between the two input pins.
The OPAx992-Q1 family (OPA992-Q1, OPA2992-Q1, and OPA4992-Q1) is a family of high voltage (40 V) general-purpose operational amplifiers. It is available in standard packages (such as SOIC, TSSOP, VSSOP, SOT-23 and SC70), and is specified from –40°C to 125°C. Widely applied in Automotive head unit, Automotive external amplifier, Emergency call (eCall), Telematics control unit (TCU), Traction inverter, HEV/EV on-board and wireless charger (OBC), HEV/EV DC/DC converter, High-side, and low-side current sensing.

The OPAx992-Q1 uses a special input architecture to eliminate the requirement for input protection diodes but still provides robust input protection under transient conditions.provides a true high-impedance differential input capability for high-voltage applications using a patented input protection architecture that does not introduce additional signal distortion or delayed settling time, making the device an excellent op amp for multichannel, high-switched, input applications.

The OPAx992-Q1 uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI from sources such as wireless communications and densely-populated boards with a mix of analog signal chain and digital components.
The internal power dissipation of any amplifier causes the internal (junction) temperature to rise. This phenomenon is called self heating. The absolute maximum junction temperature of the OPAx992-Q1 is 150°C. Exceeding this temperature causes damage to the device. The OPAx992-Q1 has a thermal protection feature that reduces damage from self heating. The protection works by monitoring the temperature of the device and turning off the op amp output drive for temperatures above 170°C.
The OPAx992-Q1 features an output stage capable of driving moderate capacitive loads, and by leveraging an isolation resistor, the device can easily be configured to drive larger capacitive loads. Increasing the gain enhances the ability of the amplifier to drive greater capacitive loads

The OPAx992-Q1 family offers excellent DC precision and AC performance. These devices operate up to 40-V supply rails and offer true rail-to-rail input/output, low offset voltage and offset voltage drift, as well as 10.6-MHz bandwidth and high output drive. These features make the OPAx992-Q1 a robust, high-performance operational amplifier for high-voltage automotive applications.
