SRC4194IPAGT

Audio Special Purpose Overview

The SRC4194IPAGT is a Texas Instruments asynchronous audio sample rate converter housed in a 32-pin TQFP package. It supports conversion ratios ranging from 1:16 to 16:1, accommodating input sample rates between 8 kHz and 192 kHz. The device features a dynamic range of 144 dB and total harmonic distortion plus noise (THD+N) of -130 dB. Designed for high-fidelity digital audio applications, it utilizes I2S and TDM interfaces for data transmission. The component operates on a single 3.3 V supply voltage and functions within an industrial temperature range of -40°C to +85°C.

Audio Special Purpose Feature Summary

• High-performance audio metrics including 144 dB dynamic range and -130 dB THD+N
• Supports input sample rates from 8 kHz to 192 kHz
• Integrated I2S and TDM serial interfaces

Audio Special Purpose Applications

• Professional audio mixing consoles
• Digital signal processing systems
• High-end home theater receivers

Audio Special Purpose Part Context

The SRC4194 belongs to the SRC419x family of asynchronous sample rate converters. This series is engineered for multi-channel audio environments requiring precise clock domain crossing. The IPAG suffix denotes the 32-lead Thin Quad Flatpack (TQFP) surface-mount package variant, distinguishing it from other pin-count options within the same functional family.

Audio Special Purpose Replacement Considerations

The SRC4193 serves as a compatible alternative within the same product family. Designers should verify that the required conversion ratio range fits the SRC4193's specifications, which support ratios from 1:16 to 16:1, similar to the SRC4194.
