For improved performance, functionality, and even lower power consumption Maxim Integrated recommends the MAX98360.The MAX98357A/MAX98357B is an easy-to-use, low-cost,digital pulse-code modulation (PCM) input Class D amplifierthat provides industry-leading Class AB audio performancewith Class D efficiency. The digital audio interfaceautomatically recognizes up to 35 different PCM and TDMclocking schemes which eliminates the need for I2C programming.Operation is further simplified by eliminatingthe need for an external MCLK signal that is typically usedfor PCM communication. Simply supply power, LRCLK,BCLK, and digital audio to generate audio! Furthermore,a novel pinout allows customers to use the cost-effectiveWLP package with no need for expensive vias (referto Application Note 6643: Optimize Cost, Size, andPerformance with MAX98357 WLP for more information).The digital audio interface is highly flexible with theMAX98357A supporting I2S data and the MAX98357Bsupporting left-justified data. Both ICs support 8 channeltime division multiplexed (TDM) data. The digital audiointerface accepts specified sample rates between 8kHzand 96kHz for all supported data formats. The ICs canbe configured to produce a left channel, right channel, or(left/2 + right/2) output from the stereo input data. The ICsoperate using 16/24/32-bit data for I2S and left-justifiedmodes as well as 16-bit or 32-bit data using TDM mode.The ICs eliminate the need for the external MCLK signalthat is typically used for PCM communication. This reducesEMI and possible board coupling issues in addition toreducing the size and pin count of the ICs.The ICs also feature a very high wideband jitter tolerance(12ns typ) on BCLK and LRCLK to provide robust operation.Active emissions-limiting, edge-rate limiting, and overshootcontrol circuitry greatly reduce EMI. A filterlessspread-spectrum modulation scheme eliminates theneed for output filtering found in traditional Class Ddevices and reduces the component count of the solution.The ICs are available in 9-pin WLP (1.345mm x 1.435mmx 0.64mm) and 16-pin TQFN (3mm x 3mm x 0.75mm)packages and are specified over the -40°C to +85°Ctemperature range.ApplicationsCamerasGaming Devices (Audio and Haptics)IoT DevicesNotebook ComputersSingle Li-ion Cell/5V DevicesSmart SpeakersSmartphonesTablets

The MAX34406 is a quad, high-side, unidirectional, current-sense amplifier that offers precision accuracy. It provides analog outputs for each of the four amplifiers that can be routed to an external ADC, and contains four overcurrent comparators with a fixed 1.0V threshold. All four comparators are logically ORed, and the result can be delayed/filtered with an external capacitor before it is fed to a latched common shutdown open-drain output pin.ApplicationsBase StationsIndustrial ControlsNetwork Switches/RoutersServersSmart Grid Network Systems

The MAX34408 and MAX34409 are two- and four-channelcurrent monitors that are configured and monitored with astandard I2C/SMBus serial interface. Each unidirectionalcurrent sensor offers precision high-side operation with alow full-scale sense voltage. The devices automaticallysequence through two or four channels and collect thecurrent-sense samples and average them to reduce theeffect of impulse noise. The raw ADC samples are comparedto user-programmable digital thresholds to indicateovercurrent conditions. Overcurrent conditions trigger ahardware output to provide an immediate indication toshut down any necessary external circuitry.ApplicationsBase StationsIndustrial ControlsNetwork Switches and RoutersServersSmart Grid Network Systems
