Texas Instruments TAS2770 Smart PA
|
|
|
|
The TAS2770 is a mono, digital input Class-D audio amplifier optimized for
|
|
efficiently driving high peak power into small loudspeakers.
|
|
Integrated speaker voltage and current sense provides for
|
|
real time monitoring of loudspeaker behavior.
|
|
|
|
Required properties:
|
|
|
|
- compatible: - Should contain "ti,tas2770".
|
|
- reg: - The i2c address. Should contain <0x4c>, <0x4d>,<0x4e>, or <0x4f>.
|
|
- #address-cells - Should be <1>.
|
|
- #size-cells - Should be <0>.
|
|
- ti,asi-format: - Sets TDM RX capture edge. 0->Rising; 1->Falling.
|
|
- ti,imon-slot-no:- TDM TX current sense time slot.
|
|
- ti,vmon-slot-no:- TDM TX voltage sense time slot.
|
|
|
|
Optional properties:
|
|
|
|
- interrupt-parent: the phandle to the interrupt controller which provides
|
|
the interrupt.
|
|
- interrupts: interrupt specification for data-ready.
|
|
|
|
Examples:
|
|
|
|
tas2770@4c {
|
|
compatible = "ti,tas2770";
|
|
reg = <0x4c>;
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
interrupt-parent = <&msm_gpio>;
|
|
interrupts = <97 0>;
|
|
ti,asi-format = <0>;
|
|
ti,imon-slot-no = <0>;
|
|
ti,vmon-slot-no = <2>;
|
|
};
