Left DAC2 Mix Gain/Attenuation Select. Least significant bit represents –1.5 dB. Referred to 2.0 V p-p DAC2
output level.
00000 = +12.0 dB Gain

= Mix Muted
Right DAC2 Mix Gain/Attenuation Select. Least significant bit represents –1.5 dB. Referred to 2.0 V p-p DAC2
output level.
00000 = +12.0 dB Gain

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
Address 0 is set to “1” (all conversions disabled); or when the DDMEN bit (DAC2 to DAC1 analog mix disabled),
the DA2EN bit (DAC2 powered down), or the ANAEN bit (analog channels powered down) in Control Register Ad-
dress 27 is reset to “0.”
