A fully built and tested discrete BJT Operational Amplifier as designed Samuel Groner. This is his SGA-SOA-2 on an improved double sided PCB.  It features a 2520 style footprint.

The typical specifications for RL = 600 Ω and Vsupply = ±18 V:

  • Input offset voltage: < 20 mV
  • Input bias current: −1.1 μA
  • Input voltage noise: 1.5 nV/√Hz at 1 kHz
  • Current noise density: 0.6 pA/√Hz at 1 kHz
  • Open loop voltage gain: 80 dB
  • Gain-bandwidth product: 40 MHz at 10 kHz
  • Unity-gain bandwidth: 15 MHz
  • Slew rate: ±14 V/μs
  • Output swing: ±17 V
  • Class A output drive: 600 Ω for full voltage swing
  • Maximum output current: ±230 mA
  • Supply current: 21 mA (no load)
