The OPA205, OPA2205, and OPA4205 (OPAx205) are the next generation of the industry-standard OPAx277 family. The OPA206 and OPA2206 are related devices with the same op-amp core, but with the added feature of input overvoltage protection ±40 V above the supplies. These devices are precision, bipolar e-trim ™ op amps with super-beta inputs. TI’s proprietary trimming technology is used to achieve a typical input offset voltage of ±4 µV (±2 µV, high grade), and a typical input offset voltage drift of ±0.08 µV (±0.04 µV, high grade).
Designed on a bipolar process, the OPAx205 provide 3.6‑MHz gain bandwidth for a mere 220 µA of quiescent current. The devices also achieve a low voltage noise density of only 7.2 nV/√ Hz at 1 kHz. The super-beta inputs of the OPAx205 have a very low input bias current of 100 pA (typical) and a current noise density of 110 fA/√ Hz.
The high performance of the OPAx205 makes these devices an excellent choice for systems requiring high precision and low power consumption, such as flow and pressure transmitters, portable data acquisition (DAQ) systems, and high-density source measurement units (SMU).
