We measure power in units of joules/second, also known as watts. An electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge. Webb31 mars 2024 · For accurate measurements, you need to WAIT after the current changes; 1Tau provides 1 Neper of accuracy (9dB or 1.5bits); 2tau provides 2 Nepers of accuracy because the RC has had twice as long to settle (18dB, 3 bits, or approximately 16% error); 5 TAU or 0.5 seconds achieves 45 dB of accuracy, nearly 0.5% accuracy. sulphur well

"Webb11 nov. 2024 · The input bias current is low enough for your needs, and being limited to +/- 5 V on a TIA trying to measure very small currents is a problem. If this is for a high volume product, fair enough, otherwise, how much pain are you willing to go through to save a few bucks? What you get for the money is +/- 15V rails and a more stable amp. \$\endgroup\$ " - Small current measurement
