(1) Output power stage includes an internal 18.5-kΩ feedback resistor. This internal resistor, in parallel with an external 249-Ω R_F and 162-Ω R_G, results in a gain of 2.5 V/V after including a nominal gain loss of 0.9935 V/V due to the input buffer and loop-gain effects.

(2) Test levels (all values set by characterization and simulation): (A) 100% tested at T_A≈ T_J≈ 25°C; over temperature limits by characterization and simulation. (B) Not tested in production; limits set by characterization and simulation. (C) Typical value only for information. DC limits tested with no self-heating. Add internal self heating to T_A for T_J.

(3) This slew rate is the average of the rising and falling time estimated from the large-signal bandwidth as: (Vpeak / √ 2) × 2π × f_–3dB.

(4) Output measured at pin 11.

(5) Currents out of pin treated as a positive polarity.

(6) Output measured at pin 11.

(7) Currents out of pin treated as a positive polarity.
