Connect IN1LN pin to left channel input PGA negative
terminal.
0 = IN1LN not connected to input PGA
1 = IN1LN connected to input PGA amplifier negative
terminal.
Connect IN1LP pin to left channel input PGA amplifier
positive terminal.
0 = IN1LP not connected to input PGA
1 = input PGA amplifier positive terminal connected to
IN1LP (constant input impedance)
IN3R Amplifier enable
0 = disabled
1 = enabled
Short circuit internal input resistor for IN3R amplifier.
0 = Internal resistor in circuit.
1 = Internal resistor shorted.
IN3L Amplifier enable
0 = disabled
1 = enabled
Short circuit internal input resistor for IN3L amplifier.
0 = Internal resistor in circuit.
1 = Internal resistor shorted.
Microphone bias enable
0 = OFF (high impedance output)
1 = ON
Microphone bias voltage control:
0 = 0.9 * AVDD
1 = 0.75 * AVDD
Enable MIC detect:
0 = Disabled
1 = Enabled
Threshold for bias current detection
000 = 160μA
001 = 330μA
010 = 500μA
011 = 680μA
100 = 850μA
101 = 1000μA
110 = 1200μA
111 = 1400μA
These threshold currents scale proportionally with
AVDD. The values given are for AVDD=3.3V.
