... the CRD3511, a value of 1.0 µF is used for C even for the highest gain setting. In many cases, a lower value because the speakers used do not have the ability to reproduce low-frequency signals. 4.4 MUTE Pin The MUTE pin must be driven to a logic low or logic high state for proper operation. To enable the amplifier, connect the MUTE pin to a logic low ...

Recommended Power-Down Sequence 1. Set the MUTE pin to the logic high state. This will mute the amplifier outputs and hold them in a high- impedance state. 2. Optionally, the SLEEP pin can now be set to a logic ...

... CS3511 amplifier’s switching pattern will degrade the measurement result. One feature of the CS3511 is that it does not require large multi-pole filters to achieve excellent performance in listening tests, usually a more critical factor than performance measurements. The CRD3511 Evaluation Board uses the filter described in formance in listening tests ...
