Projects > SG Acoustics SOA Opamp
The SOA is a simple, yet high-performance, discrete opamp designed by Samuel Groner (SG-Audio). The SGA has been through two revisions, with SOA-2 featuring improved transient response, common-mode rejection ratio, and gain-bandwidth product over the original. Thought it is designed to conform to the same footprint as the API 2520/Jensen 990 DOAs, the SOA is a unique design.
Specifications:
- 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: ±230 mA
- Current draw: 21 mA (no load)
Price: $15 for full kit
