MP1720DH-216-LF-Z - 2.7W Mono Class D Audio Amplifier | MPS
부품 번호: MP1720DH-216-LF-Z ✓ 활성MP1720DH-216-LF-Z 개요
A Class D audio amplifier is a switching power amplifier that uses pulse-width-modulated output stages rather than continuously biased linear output transistors. The MP1720 integrates 250 mΩ power MOSFETs for VIN = 3.3 V, startup and shutdown pop elimination, short-circuit protection, thermal-overload protection, and EMI-reduction circuitry. Its integrated filtering approach can eliminate the need for an output LC filter in suitable designs, helping reduce board area and simplify compact speaker-drive layouts.
The MP1720 family provides five fixed gain options and supports both internally selected and externally synchronized switching frequencies. The -216-LF-Z ordering code identifies the 10-MSOP-EP package, while the -Z suffix identifies the specific variant provided by the verified distributor listing. The exposed-pad package helps remove heat from the Class D output circuitry, although layout and thermal design still determine reliable performance.
Typical uses include portable speakers, compact consumer audio products, voice-enabled devices, sound bars, USB or battery-powered audio accessories, and small industrial or monitoring systems. The 2.7 W output capability is appropriate for low-impedance speakers in space-constrained products where efficiency, EMI control, and short solution size are more important than a high-power audio output stage.
Designers should follow the manufacturer recommended input, output, and feedback connections, place the exposed thermal pad on a copper pour, and validate EMI behavior in the final enclosure and cable configuration. The MP1720DH-216-LF-Z is also identified as RoHS compliant by the verified component listing, while detailed lead-free, REACH, AEC-Q100, and halogen-free status require confirmation from current manufacturer documentation.

일반적인 애플리케이션
MP1720DH-216-LF-Z 적합 용도: 6 애플리케이션s: Compact Portable Speaker, USB-Powered Audio Accessory, Voice Assistant Speaker, Industrial Audible Alarm, Consumer Audio Module, Battery-Powered Monitoring Device.
Compact Portable Speaker
The MP1720DH-216-LF-Z suits a compact battery-powered speaker because it delivers 2.7 W into a 4 Ω load with approximately 90% typical efficiency. Its mono Class D output reduces heat relative to a comparable linear amplifier, helping preserve battery capacity during sustained playback. The 10-MSOP-EP footprint also saves board area. The amplifier should be placed near the speaker connector with a compact output network and an exposed-pad copper area sized for the intended dissipation. Because the verified data does not specify a complete thermal resistance or maximum junction temperature, the final design must use the manufacturer thermal information and validate acoustic output, battery runtime, and enclosure temperature.
추천
USB-Powered Audio Accessory
For a USB-powered speaker or personal-audio accessory, the MP1720DH-216-LF-Z can provide 2.7 W of mono Class D output into 4 Ω while maintaining approximately 90% efficiency at the family level. This helps reduce conversion loss between the USB supply and acoustic output. Its 1 MHz or 1.3 MHz selectable carrier gives the board designer flexibility for conducted and radiated EMI optimization. Place input filtering and the amplifier return path carefully, then test the complete USB cable and enclosure because the manufacturer states that an output LC filter can be eliminated in supported EMI configurations rather than for every board arrangement.
추천
Voice Assistant Speaker
The MP1720DH-216-LF-Z is appropriate for the compact speaker section of a voice assistant because 2.7 W into 4 Ω is sufficient for close-range voice playback in a small enclosure. The full-bridge Class D structure improves efficiency, while startup and shutdown pop elimination helps suppress audible transients during voice-command activation. The five fixed gain options permit some flexibility between the audio source level and speaker sensitivity. However, the verified information does not provide the complete input-voltage range, noise spectrum, or distortion figures, so a production design should confirm those values from the official datasheet and measure microphone coupling, wake-word playback, and thermal behavior in the assembled housing.
추천
Industrial Audible Alarm
A small industrial audible alarm can use the MP1720DH-216-LF-Z to generate a 2.7 W mono Class D drive into a 4 Ω horn or speaker. The approximately 90% typical efficiency helps limit internal heating, and the integrated short-circuit and thermal-overload protections support robust operation in compact equipment. The device is not presented as a safety-rated alarm IC, so critical signaling requirements must be handled elsewhere. Design the PCB with a continuous return path, adequate copper around the exposed pad, and an output network tested against the actual speaker cable. The assembly should also be checked for startup transients and EMI because industrial environments can magnify radiation and coupling issues.
추천
Consumer Audio Module
The MP1720DH-216-LF-Z can serve as the power stage in a small consumer audio module requiring mono Class D output up to 2.7 W into 4 Ω. Its 10-MSOP-EP package supports compact module layouts, while the selectable carrier frequency provides a way to coordinate switching behavior with other circuit blocks. Five gain choices allow the module to accommodate different source sensitivities. System integrators should verify input coupling, feedback or gain configuration, and the recommended output filter using the official documentation. They should also compare measured distortion and efficiency against the audible bandwidth requirements, since those detailed parameters are not available in the supplied distributor excerpts.
추천
Battery-Powered Monitoring Device
For a battery-powered monitoring device that must announce events through a small speaker, the MP1720DH-216-LF-Z provides 2.7 W mono Class D output with approximately 90% family efficiency. That combination can extend useful acoustic reach without requiring a large heat sink in a moderate-duty-cycle design. The exposed-pad MSOP package requires careful copper placement and thermal verification. Because the verified snippets do not provide quiescent current, shutdown behavior, or maximum supply voltage, engineers should check the official datasheet before estimating battery life or configuring the supply rail. Prototype testing should include repeated alert playback, audio transients, low-battery operation, and EMI measurement with the final cable and enclosure.

설계 노트
Place the MP1720DH-216-LF-Z close to the speaker connector and use a continuous, low-impedance ground path for the bridge output. Keep the input and gain-setting network away from the switching outputs and exposed-pad area. The exposed pad must be connected to the appropriate ground copper according to the manufacturer layout, rather than left as an isolated thermal island.
Estimate dissipation from the actual supply voltage, output waveform, speaker impedance, and amplifier efficiency rather than using output power alone. Because the verified excerpts do not provide thermal resistance or maximum junction temperature, use the official datasheet for those limits and validate with the final copper area, enclosure, ambient temperature, and continuous-playback duty cycle.
The MP1720 can select a 1 MHz or 1.3 MHz switching frequency and can synchronize to an external clock. Use that flexibility to coordinate the carrier with other converters on the board, but still test radiated and conducted emissions with the actual speaker cable and enclosure. The claim that an output LC filter can be eliminated applies to supported EMI configurations and should not be generalized to every layout.
Do not substitute the MP1720DH-216-LF or MP1720DH-6-LF-P solely because both appear in the family or cross-reference search. Verify the exact gain option, electrical limits, pin names, exposed-pad connection, and ordering code against the official datasheet. Also confirm the supply range, speaker impedance, gain setting, and thermal conditions before approving a replacement.
