Description

Fig. 1. Electric fish finder circuit schematic in Autodesk Eagle format. BATT = battery, C = capacitor, CHGRND = chassis ground, GND = ground, JP = connector socket, R = resistor, SPK = speaker, VCC = voltage common collector. Integrated circuits are: INA = instrumentation amplifier INA128PA; NEB = operational amplifier NE5532; LM386 = audio amplifier LM386N-1; TLE = virtual ground TLE2425IP. This schematic matches the printed circuit board layout in Fig. 2.
