AD1991 General Description
The AD1991 is a 2-channel BTL or 4-channel single-ended class D audio power output stage. The part is configured during reset to be in either 2-channel mode or 4-channel mode.
To protect the IC as well as the connected speakers, the AD1991 provides turn-on and turn-off pop suppression, short-circuit protection, and overtemperature shutdown. To control the IC, a power-down/reset input and a mute pin are available.
The output stage can be operated over a power supply range from 8 V to 20 V.
In 2-channel mode, Transistors A1, B2, C1, and D2 are turned on by a Logic 1 on inputs INA and INC, and Transistors A2,B1, C2, and D1 are turned on by a Logic 0 on inputs INA and INC. In 4-channel mode, Transistors A1, B1, C1, and D1 are turned on by a Logic 1 on the four inputs, and Transistors A2,B2, C2, and D2 are turned on by a Logic 0 on the four inputs (see the Functional Block Diagrams).
