(1)

All voltages are measured with respect to the GND pins (5, 10), unless otherwise specified.

(2)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which specify performance limits. This assumes that the device is within the Operating

Ratings. Specifications are not ensure for parameters where no limit is given, however, the typical value is a good indication of device

performance.

(3)

Typicals are measured at 25°C and represent the parametric norm.

(4)

Limits are ensure that all parts are tested in production to meet the stated values.

(6)

AC Electrical Test; Refer to Test Circuit #2 (AC Electrical Test Circuit).

(7)

For a 4

Ω load, and with ±20V supplies, the LM1876 can deliver typically 22W of continuous average output power with less than 0.1%

(THD + N). With supplies above ±20V, the LM1876 cannot deliver more than 22W into a 4

Ω due to current limiting of the output

transistors. Thus, increasing the power supply above ±20V will only increase the internal power dissipation, not the possible output

power. Increased power dissipation will require a larger heat sink as explained in Application Information.

DC Electrical Test; Refer to Test Circuit #1 (DC Electrical Test Circuit).
