TSC2302
SLAS394 – JULY 2003
Power Consumption
The TSC2302 provides maximum flexibility to the user for control of power consumption. Towards that end, every
section of the TSC2302 audio codec can be independently powered down. The power down status of the
different sections is controlled by Reg 05h in Pg 2. The analog bypass path, headphone amplifier, mono output,
stereo DAC, left channel ADC, right channel ADC, microphone bias, crystal oscillator, and oscillator clock buffer
sections can all be powered down independently. It is recommended that the end-user power down all unused
sections whenever possible in order to minimize power consumption. Below is a table showing power
consumption in different modes of operation.

TSC2302 AUDIO CONTROL REGISTERS
TSC2302 Audio Control Register (Page 2, Address 00H)
The audio control register of the TSC2302 controls the digital audio interface, the microphone preamp gain, the
record multiplexer settings, and the ADC highpass filter pole. This register determines which ADC high pass filter
response is selected, as well as which audio inputs are connected to the stereo ADCs. The gain of the MIC input
(0 to 12 dB) is also selected. This register is also used to tell the data converters the frequency of MCLK, along
with the frequency of LRCLK (ADC and DAC sample rates). The format of the audio data is also selected.
The audio control register is formatted as follows:
