Overview
signal level detection outputs converter input overflow conditions. Both devices feature differential inputs have capability disable high pass filter applications that require digitizing input signal. These additional features, addition wide dynamic range (100 these products, position CS5334 CS5335 unique 20-bit converter offerings.
Peak Signal Level Detection There many audio systems that feature input signal level metering function; examples such systems include digital mixing consoles, multi-track recorders, (Digital Audio Tape) players, reverb units, digital audio editing systems. input signal level metering typically consists display LEDs which indicates whether input signal "clipping" (exceeding full scale input level system) within range desired recording levels from full scale). digital audio systems, this function typically accomplished with (digital signal processor) which reads input signal level from converter, performs peak detection, then sends information display. CS5334 CS5335 have capability perform peak signal level detection, which will reduce MIPS requirements enabling system designer other features DSP.
There Peak Signal Level Metering modes CS5334 CS5335 High Resolution Graph Mode. both modes, there bits Peak Signal Level (PSL) bits which output serial format following audio data bits. bits formatted differently High resolution Graph Mode, peak signal level updated toggling (Peak Update) pin.
High Resolution Mode Peak Signal Level (PSL) bits indicate whether converter input signal within (exceeding converter input level input range. eight bits have resolution 1dB. Typically, micro-controller would "interpret" data from CS5334/5 format usable display.

Overview
Graph Mode this mode, bits only provide metering levels: bits used directly drive display network. Overflow Output CS5334 CS5335 contain OVFL which indicates analog input overrange both left right channels. This goes high when overrange occurs, cleared when Peak Update toggled. This used light overrange audio system front panel. Audio Converter Family Total Audio Solutions Crystal offers complete line audio converters ranging from 18-24 resolution dynamic range.

FAQs
CS5335 Crystal's lowest cost 20-bit converter? CS5334 lowest cost 20-bit converter, CS5335 compatible with CS5334 optimal price/performance solution. When used with CS4329 20-bit DAC, what dynamic range performance loopback mode (analog analog out)? 102-103 dynamic range. What advantage does high pass filter offer over traditional calibration techniques reduce offsets? CS5335 high pass filter remove both offsets input circuitry driving internal offsets generated within ADC. digital high pass filter technique reduce offsets consistently produces zero offset which cannot achieved with traditional calibration techniques. high pass filter defeatable applications where information important. Yes.
