This document is the datasheet of UDA1342TS audio codec, which mainly introduces the product's features, applications, general description, quick reference data, ordering information, block diagram, pin definition, functional description, etc.
The Philips UDA1342TS is a single-chip 4-channel analog-to-digital converter (ADC) and 2-channel digital-to-analog converter (DAC) employing bitstream conversion techniques. Designed for low-power portable applications, it supports sample frequencies from 16 to 110 kHz and offers high pin compatibility with the UDA1341TS.
The device features advanced audio configuration including separate power control for ADC and DAC, programmable gain amplifiers (PGA), and integrated digital filters. It provides multiple format data interface support (I2S-bus, MSB-justified, LSB-justified) and includes digital sound processing capabilities such as tone control, de-emphasis, and mute functions controllable via L3-bus or I2C-bus interfaces.
