View Datasheet (opens in new tab)

CS5308P Overview

The CS5308P is an 8-channel audio ADC providing 32-bit resolution at a rate of up to 768 kHz. The CS5308P’s integrated hybrid gain control feature reduces the external pre-amp control circuitry, offering a reduced BOM and simplified design when compared with alternative solutions. The CS5308P is ideal for applications that require a combination of both high-performance and low power, offering >120 dB dynamic range and THD+N below –110 dB, all within a 25 mW/ch power budget.
