概述

Description

PAM2320BECADJR is a dual-channel Class-D audio amplifier IC. It takes analog audio inputs and provides two amplified outputs to drive small speakers in battery-powered/compact devices (phones, tablets, portable speakers, embedded electronics).
Key points:
- Single-supply operation (typical 2.5–5.5 V range).
- Two output channels (stereo).
- Built-in protections (e.g., short-circuit/overcurrent, thermal shutdown; some parts support undervoltage lockout and pop-noise minimization on power-up).
- Package: an 8-pin device (suffix JR usually denotes tape-and-reel packaging; exact package type may vary).
- Typically used in compact consumer electronics where space and power are constrained.
For exact electrical specs (output power, efficiency, THD, quiescent current), input/output configurations, and recommended application circuit, refer to the official PAM2320BECADJR datasheet from the manufacturer or distributor.

Features

PAM2320BECADJR features (concise):
- Dual-channel Class-D audio amplifier
- 2× approx. 1 W into 4 Ω at 5 V (typical)
- Wide supply: 2.5 V to 5.5 V
- High efficiency (typical >90%)
- Enable/shutdown control with mute/soft-start to suppress pops
- Protection: thermal shutdown, current limiting, short-circuit protection
- Suitable for 4 Ω–8 Ω speaker loads
- Differential or standard audio inputs with configurable gain
- Small 8‑pin package (RoHS compliant)
Note: exact output power depends on supply, load, and package conditions; consult the datasheet for precise numbers.

Package

It’s an 8-pin VQFN (3×3 mm) package. The “JR” suffix indicates Tape & Reel packaging.

Pinout

Pin count: 8 pins.
Function: Dual-channel, filterless Class-D audio power amplifier (stereo). Features differential inputs and speaker outputs.
Pinout (typical):
- INL, INR = left/right inputs
- LOUT, ROUT = left/right outputs
- VIN = supply voltage
- GND = ground
- SHDN/EN = shutdown/enable
- BYP = bypass/reference pin
Note: exact pin order may vary by package revision (D8/SOP-8); refer to the datasheet for the precise mapping.

Manufacturer

- Manufacturer: Diodes Incorporated (DIODES INC.).
- What kind of company: A global semiconductor company that designs and manufactures diodes, transistors, protection devices, and analog/power-management ICs for automotive, consumer, industrial, and communications markets.

Application

PAM2320BECADJR is a dual-channel, high-efficiency Class-D audio power amplifier. Applications include:
- Portable devices (phones, tablets, MP3 players)
- Bluetooth speakers and USB-powered speaker docks
- TVs, set-top boxes, DVD players
- Soundbars and home entertainment systems
- Embedded consumer electronics and small IoT multimedia devices
- DIY audio projects needing compact, efficient stereo amplification

Equivalent

There is no published one-to-one cross reference for PAM2320BECADJR. It’s a 2‑channel, low‑voltage Class‑D audio amplifier (PAM family). For equivalents, look for 2‑channel Class‑D amps with ~2.5–5.5 V supply and similar output. Possible near substitutes from other vendors include TI TPA2320D2/TPA2312D2, ST STA326, and Maxim MAX98306. Always verify against datasheets or use distributor cross-reference tools.
