Working Principle
Two independent op-amps share common power rails. Input common-mode range includes ground (single-supply operation). Output swings to within 1.5V of VCC. Internal compensation ensures stability at unity gain. The dual configuration enables stereo amplification, cascaded filters, or differential amplification in one package.
Applications
- General-purpose amplification
- Active filter
- Buffer / follower
- Sensor signal conditioning
