Analog Interface
3.2.1
Line Inputs
The TLV320AIC23B has line inputs for the left and the right audio channels (RLINEIN and LLINEIN). Both line inputs
have independently programmable volume controls and mutes. Active and passive filters for the two channels
prevent high frequencies from folding back into the audio band.
The line-input gain is logarithmically adjustable from 12 dB to –34.5 dB in 1.5-dB steps. The ADC full-scale range
is 1.0 VRMS at AVDD = 3.3 V. The full-scale range tracks linearly with analog supply voltage AVDD. To avoid distortions,
it is important not to exceed the full-scale range.
The gain is independently programmable on both left and right line-inputs. To reduce the number of software write
cycles required. Both channels can be locked to the same value by setting the RLS and LRS bits (see Section 3.1.3).
The line inputs are biased internally to VMID. When the line inputs are muted or the device is set to standby mode,
the line inputs are kept biased to VMID using special antithump circuitry. This reduces audible clicks that otherwise
might be heard when reactivating the inputs.
For interfacing to a CD system, the line input should be scaled to 1 VRMS to avoid clipping, using the circuit shown
in Figure 3-3.

Figure 33. Analog Line Input Circuit
R1 and R2 divide the input signal by two, reducing the 2 VRMS from the CD player to the nominal 1 VRMS of the AIC23B
inputs. C1 filters high-frequency noise, and C2 removes any dc component from the signal.
