Left Auxiliary 2 Mix Mute
0 = Mix Enabled
1 = Mix Muted
Left Auxiliary 2 Mix Gain/Attenuation Select. Least significant bit represents –1.5 dB. Referred to
2.0 V p-p DAC1 output level.
00000 = +12.0 dB Gain
01000 = 0.0 dB
11111 = –34.5 dB Attenuation
Right Auxiliary 2 Mix Mute
0 = Mix Enabled
1 = Mix Muted
Right Auxiliary 2 Mix Gain/Attenuation Select. Least significant bit represents –1.5 dB. Referred to
2.0 V p-p DAC1 output level.
00000 = +12.0 dB Gain
01000 = 0.0 dB
11111 = –34.5 dB Attenuation
Reserved for future expansion. To ensure future compatibility, write “0” to all reserved bits.
Initial default state after reset: 1000 1000 1000 1000 (8888 hex). Cleared to default and cannot be written to when:
the RESET pin is asserted LO; when the PWRDWN pin is asserted LO; when the PDNO bit in Control Register Ad-
dress 0 is set to “1” (all conversions disabled); or when the AAMEN bit (analog input to analog mix disabled), or the
ANAEN bit (analog channels powered down) in Control Register Address 27 is reset to “0.”
