Device Overview
MP7740DN-LF-Z is a MPS 15 W mono Class-D single-ended audio amplifier in a SOICW24-18L package. For substitution or design review, the strongest comparison points are Device Function (15 W mono Class-D single-ended audio amplifier), Output Power (15 W), Thd Plus Noise (0.05 %).
Selection-Critical Data
| Parameter | Confirmed Data | Why It Matters |
|---|---|---|
| Device Function | 15 W mono Class-D single-ended audio amplifier | Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared. |
| Output Power | 15 W (VDD=24 V, load=4 ohm) | Defines available output-power headroom under the stated operating conditions; compare it at the same frequency, modulation/load and bias. |
| Thd Plus Noise | 0.05 % (output=1 W) | Defines combined harmonic distortion and noise and therefore the fidelity/noise performance of the audio signal path. |
| Operating Supply Range | 9.5 to 36 V | Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. |
| Switching Frequency | up to 1 MHz | Defines the converter or clock switching rate and affects timing, passive-component selection, losses and EMI; it is not an RF operating band. |
| Exact Package | SOICW24-18L | Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility. |
Analog Selection Notes
For device function, 15 W mono Class-D single-ended audio amplifier is the approved value. Defines the device function or architecture that a compatible replacement must preserve before secondary ratings are compared.
SOICW24-18L is the stated exact package value. Determines PCB footprint, pinout, mechanical assembly and orderable-variant compatibility.
15 W is the stated output power value. Defines available output-power headroom under the stated operating conditions; compare it at the same frequency, modulation/load and bias. Technical condition: VDD=24 V, load=4 ohm. For thd plus noise, 0.05 % is the approved value. Defines combined harmonic distortion and noise and therefore the fidelity/noise performance of the audio signal path. Technical condition: output=1 W.
9.5 to 36 V is the stated operating supply range value. Defines DC current demand and therefore contributes to power consumption, rail loading and thermal burden. At up to 1 MHz, the switching frequency defines the converter switching rate and affects passive-component selection, losses and EMI.
