A correctly chosen fuse, which doesn't melt until the current exceeds. This is a cheap price to pay in return for enhanced safety. The switch is irreversible, and the fuse must be thrown away and replaced. Once the wire has melted, the circuit is broken. WebTo make a fuse, place a short piece of wire that melts at a low temperature in the circuit. The integrated PLL on the device removes the requirement for a system clock (commonly known as master clock), allowing a 3-wire I 2S connection and reducing system EMI.Fire to the Fuse (Ft. The integrated line driver surpasses all other charge-pump-based line drivers by supporting loads down to 1 kΩ, allowing the PCM514x to drive up to 10 products in parallel, such as LCD TV, DVDR, and AV receivers. The PCM514x provides 2.1-V RMS ground centered outputs, allowing designers to eliminate DC-blocking capacitors on the output, as well as external muting circuits traditionally associated with single-supply line drivers. Members of the PCM514x family integrate a fully programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators, and other differentiating features to their products. The PCM514x uses the latest generation of TIs advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter. The PCM514x devices are a family of monolithic CMOS-integrated circuits that include a stereo digital-to-analog converter and additional support circuitry in a small TSSOP package. 1.8-V or 3.3-V Fail-Safe LVCMOS Digital Inputs.Automatic Power-Save Mode When LRCK And.PCM Data Formats: I 2S, Left-Justified, Right.Integrated High-Performance Audio PLL with.Intelligent Muting System Soft Up or Down Ramp.Selectable Digital-Filter Latency and Performance.
