6.5 Electrical Characteristics (continued)

V_DD= 3.3 V, C_PD⁽¹⁾= 1 pF, EN = 0 V, IDC_EN = 3.3 V, R_L= 100 Ω(Output is AC-coupled for AC performance parameters;

for DC performance parameters load is referenced to 1V), and T_A= 25℃(unless otherwise noted)

EN and IDC_EN pins input bias current

(1) Input capacitance of photodiode.

(2) Average of rising and falling slew rate.

(3) Pulse width extension measured at 50% of pulse height of square wave.

(4) Gain measured at the amplifier output pin when driving a 100-Ω resistive load. At higher resistor loads the gain increases.

(5) Photodiode anode biased to a negative voltage

(6) Photodiode cathode biased to a positive voltage

(7) Device cannot withstand continuous short-circuit.

(8) Enabling the ambient light cancellation loop adds noise to the system.
