I am looking for an alternative replacement for the TLV320AIC32 that has a more powerful headphone amplifier (~2W).
The replacement needs to have an I2S audio input digital interface and also be able to generate the master clock from the bit clock input using an internal PLL, just like the TLV320AIC32 does.
I am using a microprocessor (dsPIC33EP256MU810) to generate the word clock (44.1kHz) and the bit clock (2.822400MHz). The TLV320AIC32 is configured for an audio data word length of 32-bits and receives bluetooth audio (I2S) from a Bluegiga WT32i bluetooth module. The microprocessor configures the TLV320AIC32 via the I2C interface.
I don't actually need all the other features that the TLV320AIC32, such as ADC (microphone) inputs and 3D DSP etc. But I would like to use the software drivers I have written for the microprocessor. These drivers configure the CODEC (currently via I2C, but SPI is an option) and use the I2S interface for the audio input.
The TLV320AIC32 works well in my application, I just need a higher power amplifier. I dont use most the features that the TLV320AIC32 has, so if anything its over the top.
Can anyone recommend a suitable alternative please ?
