CS35L00-CNZR

Audio Amplifiers Overview

The CS35L00-CNZR is a mono Class-D audio amplifier from Cirrus Logic, housed in a thermally enhanced 10-pin DFN package. It delivers up to 2.8 W into a 4 Ω load at 10% THD+N and 1.7 W into an 8 Ω load. The device operates on a supply voltage range of 2.5 V to 5.5 V with a maximum ambient temperature of +70°C. Key electrical parameters include a signal-to-noise ratio of 98 dB (A-weighted) and total harmonic distortion plus noise of 0.02% at 1 W output.

Audio Amplifiers FAQ

How is the amplifier gain configured?

The gain is pin-selectable via the GAIN_SEL input. Pulling the pin low sets the gain to +12 dB, while pulling it high sets the gain to +6 dB.

What protection features are included?

The CS35L00 includes integrated protection for output short-circuits and thermal overload, both featuring automatic recovery functionality.
