The recommended power-up sequence is to apply VDD first, followed by VDDIO, and then the clock signal. This ensures proper initialization of the device.
To configure the TLV320AIC26IRHBG4 for stereo audio, set the STEREO bit in the Audio Interface Control Register (AIC26_REG_0) to 1. This enables stereo mode and allows the device to process left and right audio channels separately.
The maximum input signal level that the TLV320AIC26IRHBG4 can handle is 2.2 Vrms. Exceeding this level may result in signal distortion or clipping.
To optimize the TLV320AIC26IRHBG4 for low power consumption, use the Power Management Register (AIC26_REG_14) to enable power-down modes for unused blocks, reduce the clock frequency, and adjust the bias voltage. Additionally, consider using the device's built-in low-power modes, such as the 'Low Power' mode, which reduces power consumption by up to 50%.
The recommended layout and routing for the TLV320AIC26IRHBG4 involves keeping analog and digital signals separate, using a solid ground plane, and minimizing trace lengths and impedance mismatches. Additionally, ensure that the device's power supply pins are decoupled with capacitors and that the clock signal is routed away from sensitive analog signals.
