1 / 18 page  1 (17) DA9116.005 22 November, 2005 MAS9116 Stereo Digital Volume Control • Signal Voltage up to ± ± ± ± 18V • Two Independent Channels • Use of Differential DACs Possible • Serial Control Registers DESCRIPTION MAS9116 is a stereo volume control for audio systems, which require high output voltages (AC3). It has a 16-bit serial interface, which controls two audio channels. Simple serial interface allows microcontroller to control many MAS9116 chips on the same PCB board. “Clicking” between gain changes is eliminated by changing gain only when zero crossing has been detected from the signal. The use of external operational amplifier provides flexibility for the operating voltage, signal swing, noise floor and cost optimization. FEATURES APPLICATION • Zero Detection for Gain Changes • Gain Range +15.5db…-111.5dB • 0.5 dB Step Size • Mute Pin and Register • Power On/Off Transient Suppression • Signal Peak Level Comparator with Adjustable Reference • High End Audio Systems • Multichannel Audio Systems BLOCK DIAGRAM CONTROL R1 R2 R3 R1 R2 R3 ZERO CROSSING LFO RFO AGND AVCC VIN VIN VOUT VOUT ZERO CROSSING XCS XMUTE PEAK DETECTOR DAC 8 PEAK DETECTOR DATA LMO RMO CCLK DVCC DGND LIN RIN RGND LGND MAS9116 |
