概要
Description
MAX9724AETC+T is a Maxim Integrated multi-channel audio power amplifier IC used to drive small loudspeakers in portable electronics. It typically integrates multiple amplifier channels (stereo/quad) in a single package, offering high efficiency (Class D/AB variants), low quiescent current, and built-in protection (short-circuit, overcurrent, thermal shutdown). It supports single-ended or differential inputs, includes mute/standby and pop-noise suppression features, and operates from a low-voltage supply (roughly 2.7–5.5 V). The AETC+T suffix indicates packaging and lead-free compliance (Tape-and-Reel shipping). Typical applications include mobile devices, portable speakers, headsets, and IoT devices. For exact specifications (channel count, output power, THD, efficiency), consult the MAX9724AETC+T datasheet and ordering guide.
Equivalent
There is no guaranteed, exact drop‑in equivalent to MAX9724AETC+T. For functional substitutes consider similar stereo/headphone amplifier ICs from TI (TPA6130A2/TPA6131), Cirrus Logic (CS43L22 family), or Analog Devices (ADAU1761 series). Always verify pinout, supply voltages, output power, mute/gain controls and thermal specs before substituting; consult distributor cross‑reference or Analog Devices/Maxim support for exact matches.
Features
Here are the typical features of the MAX9724AETC+T (datasheet should be consulted for exact specs):
- Four-channel, filterless Class-D audio amplifier
- High efficiency; no external output filters required
- Supports 4–8 ohm speaker loads
- Clickless turn-on/turn-off with mute/standby control
- Built-in protection: thermal shutdown, overcurrent/short-circuit protection
- Spread‑spectrum modulation to reduce EMI
- Differential input capability with adjustable gains
- Wide operating supply range and low quiescent current
- Package: 32-pin QFN in AETC+T variant (tape-and-reel)
Note: Exact voltage range, power per channel, and control interfaces vary by revision. Please refer to the official MAX9724AETC+T datasheet for precise specifications and recommended operating conditions.
