EVALUATION KIT AVAILABLE MAX98089 Low-Power, Stereo Audio Codec with FlexSound Technology General Description Features S 5.6mW Power Comsumption (DAC to HP at 97dB DR) The MAX98089 is a full-featured audio codec whose high performance and low power consumption make it ideal S 101dB DR Stereo DAC (8kHz < f < 96kHz) S for portable applications. S 93dB DR Stereo ADC (8kHz < f < 96kHz) S Class D speaker amplifiers provide efficient amplification S Stereo Low EMI Class D Amplifiers for two speakers. Low radiated emissions enable com- 1.7W/Channel (8I, V = 5.0V) SPK VDD 2.9W/Channel (4I, V = 5.0V) SPK VDD pletely filterless operation. Integrated bypass switches optionally connect an external amplifier to the transducer S Efficient Class H Headphone Amplifier when the Class D amplifiers are disabled. S Differential Receiver Amplifier/Stereo Line Outputs The IC features a stereo Class H headphone amplifier S 2 Stereo Single-Ended/Mono Differential Line Inputs that utilizes a dual-mode charge pump to maximize effi- ciency while outputting a ground referenced signal that S 3 Differential Microphone Inputs does not require output coupling capacitors. S FlexSound Technology 5-Band Parametric EQ The IC also features a mono differential amplifier that can Automatic Level Control (ALC) also be configured as a stereo line output. Excursion Limiter Two differential analog microphone inputs are available as Speaker Power Limiter well as support for two PDM digital microphones. Integrated Speaker Distortion Limiter Microphone Automatic Gain Control switches allow for an additional microphone input as well and Noise Gate as microphone signals to be routed out to external devices. 2 S Dual I S/PCM/TDM Digital Audio Interfaces Two flexible single-ended or differential line inputs may be connected to an FM radio or other sources. S Asynchronous Digital Mixing Integrated FlexSoundK technology improves loudspeak- S Supports Master Clock Frequencies from 10MHz to 60MHz er performance by optimizing the signal level and fre- quency response while limiting the maximum distortion S RF Immune Analog Inputs and Outputs and power at the output to prevent speaker damage. S Extensive Click-and-Pop Reduction Circuitry Automatic gain control (AGC) and a noise gate optimize S Available in 63-Bump WLP Package (3.80mm x the signal level of microphone input signals to make best 3.30mm, 0.4mm Pitch) and 56-Pin TQFN Package use of the ADC dynamic range.
