A new scheme for digitally operating an 8 channel high performance analog volume control is proposed. Along withbeing I2C/SPI compatible, this scheme is faster and less complex than existing solutions due to its inherent advancedsupport for group/individual addressing. The volume control varies monotonically all the way from -96 dB to+22 dB in 0.25 dB steps. The chip achieves 110 dB THD+N, 1.8 μVrms total integrated noise and an inter-channelisolation of greater than 120 dB between power supplies of ±5 V as well as ±9 V.
