Me310-diff amp
About the Me310-diff amp PCB
Me310-diff amp is an open source PCB design by eshazen, published on GitHub. It is a 2-layer board measuring 63.5 × 63.5 mm, with 20 components from 9 distinct parts.
Other key parts include the LM741. By type, the board carries 8 test points, 6 resistors, 4 capacitors and 2 ICs.
From the project
Various small projects for EPIC and ENG classes
This is a clone of an existing design with a differential amplifier based on the classic 741 op-amp. It has +/- signal inputs, a single-ended output, and power supply connections.
Power supplies can be up to +/-15V per the specs of the 741.
With both + and - inputs connected, the differential voltage gain is 100.0. If the "Sig+" input is unused, it must be grounded, else the gain drops to 10.
