Item details

Handmade

A fully built and tested discrete BJT Operational Amplifier as designed Samuel Groner and manufactured in the USA by KAD Products.

This is his SGA-SOA v2 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)
