OPA838 - Voltage-Feedback Op Amp

General Description

The OPA838 decompensated voltage feedback operational amplifier provides a high 300-MHz gain bandwidth product with 1.8-nV/√Hz input noise voltage, requiring only a trimmed 0.95-mA supply current.

Key Features

  • 1 Gain Bandwidth Product: 300 MHz.
  • Very-Low (Trimmed) Supply Current: 950 µA.
  • Bandwidth: 90 MHz (AV = 6 V/V).
  • High Full-Power Bandwidth: 45 MHz, 4 VPP.
  • Negative Rail Input, Rail-to-Rail Output.
  • Single-Supply Operating Range: 2.7 V to 5.4 V.
  • 25°C Input Offset: ±125 µV (Maximum).
  • Input Offset Voltage Drift: < ±1.6 µV/°C (Maximum).
  • Input Voltage Noise: 1.8 nV/√Hz (> 200 Hz).
  • Input Current Noise: 1 pA/√Hz (> 20.
