4972 puhul rõhutatakse toite jalgadel kondede olemasolu:
LME49720 requires adequate power supply decoupling to ensure a low total harmonic distortion (THD). Place a low equivalent-series-resistance (ESR) ceramic capacitor, typically 0.1 µF, within 2 mm of the V+ and V- pins. This choice of capacitor and placement helps with higher frequency transients, spikes, or digital hash on the line. In addition to the 0.1 µF ceramic capacitor, it is recommended to place a 2.2 µF to 10 µF capacitor on the V+ and V- pins. This larger capacitor acts as a charge reservoir, providing energy faster than the board supply, thus helping to prevent any droop in the supply voltage.

Texas Instruments-il on ametlik nimekiri mikroskeemidest. Kasutan seda ise, kui vanat enam ei toodeta ja vajan uut sarnast:

Ennast huvitaks prantslaste SPARKOS isetehtud mikroskeemid, kuid hind pärsib ostmist
