The OPA206 and OPA2206 (OPAx206) are the next generation of the industry-standard OPAx277 family with the additional feature of input overvoltage protection. These precision, bipolar, e-trim™ op amps with super-beta inputs use TI’s proprietary trimming technology to achieve an input offset voltage of ±8 µV (typ) and an input offset voltage drift of ±0.08 µV/°C (typ). The input overvoltage protection activates when the input signal exceeds the supply range and offers protection up to 40 V beyond either supply. This feature eliminates the need for external circuitry to prevent amplifier damage.

Designed on a bipolar process, the OPAx206 provide a speed-to-power ratio of 3.6 MHz for a mere 220 µA (typ). The devices also achieve a low voltage noise density of only 8 nV/√Hz at 1 kHz. Thanks to super-beta inputs, the OPAx206 have a very low input bias current of 100 pA (typ) and a current noise density of 110 fA/√Hz.

The high performance of the OPAx206 make these devices an excellent choice for systems requiring high precision and low power consumption, such as high-density analog input modules in programmable logic controllers, field and portable instrumentation systems, and source measurement units. The OPA205 and OPA2205 are related devices with the same op amp core without the input protection, but with improved broadband noise (7.2 nV/√Hz).
