OPA205 - Op Amps

General Description

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.

Key Features

  • e-trim™ operational amplifier performance.
  • Low offset voltage: 25 µV (max), 15 µV (max, high grade).
  • Low offset voltage drift: ±0.5 µV/°C (max), ±0.2 µV/°C (max, high grade).
  • Super beta inputs.
  • Input bias current: 500 pA (max).
  • Input current noise: 110 fA/√Hz.
  • Low noise.
  • 0.1 to 10-Hz: 0.2 µVPP.
  • Voltage noise: 7.2 nV/√Hz.
  • AOL, CMRR, and PSRR: > 126 dB (full temperature range).
  • Gain bandwidth produc.
