CS48L10-CNZR

CS48L10-CNZR is Cirrus Logic’s CS48L10 audio IC—a compact, high-efficiency mono Class‑D power amplifier for embedded devices. It combines a digital audio input interface (I2S/left-justified) with a built‑in Class‑D speaker driver, power management, and basic audio processing. Typical features include adjustable gain, mute/standby control, short‑circuit and thermal protection, pop-noise suppression, and diagnostic/status outputs. The CNZR suffix identifies a specific RoHS‑compliant package variant (form factor/manufacturing code). Applications include mobile devices, wearables, Bluetooth speakers, headsets, and other IoT gadgets that need efficient, space‑saving audio amplification. Design involves programming the IC via its register interface and following the datasheet for power rails, input formats, and layout. In short: CS48L10-CNZR is an embedded, single‑package Class‑D audio amplifier with optional processing for compact consumer audio.
