BD34705KS2 ROHM

Datasheet Sound Processors for AV Receiver Systems 7.1ch Sound Processor with Built-in Micro-step Volume BD34705KS2 General description Key Specifications The BD34705KS2 is an 8ch independent volume system. Total harmonic distortion: 0.0004%(Typ.) The system is designed to allow 7.1ch surround system Maximum output voltage: 4.2Vrms(Typ.) application. It is improvement that sound quality more Output noise voltage: 1.2Vrms(Typ.) than the conventional products. Micro-step volume can Residual output noise voltage: 1.0Vrms(Typ.) reduce the switching pop noise during volume attenuation, Cross-talk between channels: -105dB(Typ.) so a high quality audio system could be achieved. Cross-talk between selectors: -105dB(Typ.) 8ch triple input selectors for zone 3 and multi channel input enable the connection with a number of sources. Package W(Typ.) x D(Typ.) x H(Max.) SQFP-T64 14.00mm x 14.00mm x 1.50mm Features 8ch input selectors (It is extendable to up to 14 by other functions and exclusion) Micro-step volume can reduce the switching pop noise during volume attenuation. Zone 3 is supported. Built-in 2ch Volume for ZONE output 2-wire serial bus control, corresponding to 3.3/5V. Applications SQFP-T64 Suitable for the AV receiver, home theater system, etc. Typical Application Circuit Figure 1.
