Note 1:
All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2:
Guaranteed by design. Not production tested.
Note 3:
PSRR is specified with the amplifier input connected to GND through C
IN
.
Note 4:
See Table 3 for details of the mute levels.
Note 5:
The value of R
B
dictates the minimum beep signal amplitude (see the
Beep Input
section).
