Description

The OPA2206 is the next generation of the industry-standard OPAx277 family with the additional feature of input overvoltage protection. The device is a precision bipolar, e-trim operational amplifier with super beta inputs. The device uses TI’s proprietary trimming technology to achieve an impressive input offset voltage of ±2 μV (typ) and an input offset voltage drift of ±0.04 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 cumbersome circuitry to prevent the amplifier from damages.

Designed on a bipolar process, the OPA2206 provides a superb speed-to-power ratio of 3.6 MHz for a mere 220 μA. The device also achieves a low voltage noise density of only 8 nV/√Hz at 1 kHz. Thanks to super-beta inputs, the OPA2206 has a very low input bias current of 100 pA (typ) and a current noise density of 110 fA/√Hz.

The high performance of the OPA2206 makes this device 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 OPA2205 is a related product with the same op amp core, without the input protection but with improved broadband noise (7.2 nV/√Hz).
