92HD91B1X5NLGIWCX8

Overview

The 92HD91B1X5NLGIWCX8 is an audio codec manufactured by Tempo Semiconductor, a subsidiary of Renesas Electronics Corporation. It integrates four-channel Class D amplifiers and auxiliary inputs within a single package. The device supports high-resolution audio processing with a 24-bit resolution and conversion rates up to 192 kHz. It contains two analog-to-digital converters (ADCs) and two digital-to-analog converters (DACs). Operating voltage ranges from 3.135 V to 5.25 V, with a typical operation at 3.3 V or 5 V. The component functions within a temperature range of -40°C to +85°C and is housed in a QFN-48 surface-mount package.
