Audio Amplifier Circuit - UC Santa Barbara

Figure 1-5 – LM386 internal circuit and 8-pin DIP pin assignments. This is an old chip that has been a popular choice for low-power audio applications for many years. There are many other audio amp ICs on the market (LM380 and LM383 are similar but higher-power amps from National), but the LM386 is sufficient for our purposes.

Battery Internal Resistance-11 - Energizer

Open circuit voltage = 1.6 Volts 1.6 Volts – 0.1 Volts = 1.5 Volts (expected closed circuit voltage) In general, internal resistance will rise during discharge due to the active materials within the battery being used. However, the rate of change during discharge is not consistent. Battery chemistry, depth of discharge, drain rate and

Sequential Circuit Design - University of Pittsburgh

Elec 326 14 Sequential Circuit Design Select the Flip-Flop Type The four main types of flip-flops are SR, D, T and JK. The choice of flip-flop type can affect the complexity of the combinational logic in the resulting sequential circuit. Of three common types, the most versatile is the JK, since it can be easily converted into the other two.
