Test levels: (A) 100% tested at +25°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization

and simulation. (C) Typical value only for information.

(2)

Not directly measureable; calculated using noise gain of 101 as described in the Applications section, Audio Performance.

(3)

Input Offset Voltage Drift, Input Bias Current Drift, and Input Offset Current Drift are average values calculated by taking data at –40°C

and +85°C, computing the difference, and dividing by 125.
