The OPA4206APWR is a low noise four-channel operational amplifier with input overvoltage protection.

Product: OPA4206APWR

Type: Operational amplifier

Package: TSSOP-14

Instructions:

The Texas Instruments OPAx206 precision operational amplifier is the next generation of the industry-standard OPAx277 family with input overvoltage protection (OVP) add-on. The device is a precision bipolar e-trim operational amplifier with a super beta input. The device uses TI 'proprietary fine-tuning technology to achieve an impressive ±2µV (typical) input offset voltage and ±0.04µV/°C (typical) input offset voltage drift. Input overvoltage protection activates when the input signal is outside the power supply range, providing protection up to 40V on either power supply. This feature eliminates the need for cumbersome external circuitry and prevents damage to the amplifier.
