6.3.3 Input Channel Configuration

The TAC5311-Q1 consists of two pairs of analog input pins (INxP and INxM) that can be configured as either differential or single-ended inputs for the recording channel. The device supports mono recording using the single-channel ADC. The input source for the analog pins can be either analog microphones or line, aux inputs from the system board. Table 6-9 describes how to set the input configuration for the record channel.

Table 6-9 Input Source Selection for the Record Channel
P0_R80_D[7:6] : ADC_CH1_INSRC[1:0]INPUT CHANNEL 1 RECORD SOURCE SELECTION
00 (default)Analog differential input for channel 1
01Analog single-ended input for channel 1
10 or 11Reserved (do not use this setting)

The device has an integrated mux to swap the recording channels using the ADC_CH_SWAP (P0_R119_D[1]) register.

The device supports the input DC fault diagnostic feature for microphone recording with the DC-coupled inputs configuration. For AC Coupled input, the ADC channel-2 pins IN2P and IN2M can be used as DIN1P and DIN1M for diagnostics

For the DC-coupled line input configuration, the DC common-mode difference (INxP – INxM) for the analog input pins must be 0V to support the 10VRMS full-scale differential input. The DC differential common-mode voltage is later filtered out by the digital high-pass filter and the digital output full-scale corresponds to the 10VRMS AC signal in this case.

Figure 6-15 and Figure 6-16 show how to connect a DC-coupled microphone for a differential and single-ended input, respectively. The value of the external bias resistor, R1, must be appropriately chosen based upon the microphone impedance. For a differential input, the value of the external bias resistor is recommended to be used for half of the microphone impedance, whereas for a single-ended input, the external bias resistor is recommended to be the same as the microphone impedance.

In AC-coupled mode, the value of the coupling capacitor must be so chosen that the high-pass filter formed by the coupling capacitor and the input impedance do not affect the signal content. At power-up, before proper recording can begin, this coupling capacitor must be charged up to the common-mode voltage. For single-ended input configuration, the INxM pin must be grounded after the AC coupling capacitor in AC-coupled mode.

Figure 6-17 and Figure 6-18 show how to connect an AC-coupled microphone or line source for a differential and single-ended input, respectively. In AC-coupled mode, the device input pins INxP and INxM, must be biased appropriately for the DC common-mode value either using the on-chip MICBIAS output voltage along with external bias resistor, R0, or using an external bias generator circuit. The maximum value for resistor R0 depends upon the signal swing and the Microphone BIAS value programmed. See the TAC5xxx-Q1 AC Coupled External Resistor Calculator to calculate the R0 value for the desired system configuration.

If the application uses digital PDM microphones for the recording, GPIO1, GPIxA and GPO1A pins can be reconfigured in the device to support up to four channels for the digital microphone recording (when the analog channels are not used). The device can also support simultaneous recording on one analog and three digital channels. The device supports up to one analog and up to four digital microphone channels and can support the simultaneous recording on four channels at a given time. These combinations can be enabled using the INTF4_CFG (B0_P0_R19) register. More details on enabling the PDM channels are present in Section 6.3.6.
