Description for the OPA2205

The OPA2205 is the next generation, precision, bipolar, e-trim™ operational amplifier featuring super beta inputs, and is an upgradeto the industry-standard OPA2277. Through the combination of a bipolar amplifier core and a digitaltrim, the OPA2205 achieves very low offset (±25 µV, max), offset drift (±0.3 µV/°C, max) and noise(7.2 nV/√Hz, typ).

The high dc and ac performance of the amplifier, along with a 3.6-MHz bandwidth andlow-power consumption (250 µA, max), make the OPA2205 an excellent choice for systems that requirehigh precision and low power consumption, such as high-density data-acquisition systems (DAQ),source measurement units (SMU), and string inverters. The integrated EMI/RFI filter reduces systemerrors by eliminating unwanted RF-injected signals from neighboring circuits and other electronicsystems.

The OPA2205 amplifier is available in a standard-pinout, VSSOP package, and operatesacross the extended industrial ambient temperature range of –40°C to +125°C.
