Product description
A dual-op-amp amplifier for DC signals provides two independent gain stages for preconditioning analog measurement signals or audio inputs. The circuit uses two operational amplifier ICs in a non-inverting configuration, allowing both channels to operate simultaneously without influencing each other.
The supply voltage must be between +/- 12 V and +/- 15 V; the module does not operate reliably with single-ended voltages. Each channel can be adjusted separately using trimmer potentiometers. The RCA outputs enable direct connection to audio inputs or analog measuring instruments.
Applications include signal preparation for audio mixers, laboratory and measurement amplification of sensor outputs, and DJ and studio setups. It is also suitable for hobby electronics enthusiasts testing amplifier circuits.
The board is supplied without an enclosure or power supply. The operational amplifier ICs are not included and must be added separately; various types, such as the TL072 or similar, can be used as long as they are specified for the intended operating voltages. The polarity of the power supply must be checked before operation.
Safety information
Incorrect power supply polarity will immediately destroy the operational amplifiers. This module is not intended for installation in the household electrical system and is exclusively for building prototypes and for testing and development purposes. A qualified electrician must be consulted when working on or near electrical installations.
