WM8940CGEFL/RV

Overview

The WM8940CGEFL/RV is a mono audio CODEC with an integrated speaker driver, designed for portable applications. It features a 24-bit resolution and supports sample rates from 8 to 48 kHz. The device operates on supply voltages of 2.5 V to 3.6 V for analog sections and 1.71 V to 3.6 V for digital supplies. It includes one ADC and one DAC, providing SNR values of 94 dB for the ADC and 98 dB for the DAC. The component utilizes a 2-Wire or 3-Wire serial interface and is housed in a 24-lead QFN package (4x4x0.9 mm).

Feature Summary

Integrates a high-quality mono CODEC with an on-chip BTL speaker driver capable of delivering up to 0.4 W into an 8 Ω load.
Supports differential or single-ended microphone inputs with programmable gain amplifiers and automatic level control functions.
Includes advanced digital filtering capabilities such as a programmable high-pass filter for wind noise reduction and four fully-programmable notch filters.

Applications

Digital still cameras
Camcorders
General purpose mono audio systems

Procurement Notes

Verify the specific ordering suffix RV indicates tape and reel packaging when sourcing this component. Confirm that the moisture sensitivity level corresponds to MSL3 requirements for storage and handling prior to surface mount assembly. Ensure compatibility with the specified operating temperature range of -25 °C to +85 °C for the intended application environment.

Selection Notes

Select this component for designs requiring a compact mono audio solution with integrated power amplification. Consider the low voltage operation capability where digital supplies can be reduced to 1.71 V for power savings. Verify that the available analog inputs and mixing capabilities meet the system's signal routing requirements without needing external preamplifiers.

Part Context
