Overview: Product Folder Order Now Technical Documents Tools & Software Support & munity Reference Design OPA837, OPA2837 SBOS673D – SEPTEMBER 2017 – REVISED DECEMBER 2018 OPAx837 Low-Power, Precision, 105-MHz, Voltage-Feedback.

General Description

The OPA837 and OPA2837 are single- and dualchannel unity-gain stable, voltage-feedback amplifiers that provide among the highest MHz per mW of bandwidth versus power among precision op amps.

Using only 600 µA per channel on a single 5-V supply, these 3.0-mW devices deliver 105-MHz bandwidth at a gain of 1 V/V.

The very low trimmed offset voltage of ±130 µV (maximum) es with a typical (±1σ) drift of ±0.4 µV/°C.

Key Features

  • 1 Bandwidth: 105 MHz (AV = 1 V/V).
  • Very Low (Trimmed) Supply Current: 600 µA.
  • Gain Bandwidth Product: 50 MHz.
  • Slew Rate: 105 V/µs.
  • Negative Rail Input, Rail-to-Rail Output.
  • Single-Supply Operating Range: 2.7 V to 5.4 V.
  • 25°C Input Offset: ±130 µV (Max).
  • Input Offset Voltage Drift (DCK Package): < ±1.6 µV/°C (Maximum).
  • Input Voltage Noise: 4.7 nV/√Hz (> 100 Hz).
  • HD2:.
  • 120 dBc at 2 VPP, 100 kHz.
