The WM8768GEDS/RV is a low power multi-bit, differential adc and dac converter from Wolfson Microelectronics. It is an integrated circuit (IC) designed for audio, telecommunication and other data processing applications. The device is available in standard 8-lead plastic, SOIC and TSSOP packages for a variety of system designs.

The WM8768GEDS/RV is a low power multi-bit differential ADC/DAC converter, ideal for applications where data accuracy, power budget and speed are a priority. It provides excellent linearity and dynamic range and is suitable for ADC/DAC applications ranging from direct digital synthesis and sample rate conversion, to test, measurement and digital audio.

The WM8768GEDS/RV is configured to work in a multi-bit format and is intended for applications where higher resolution is required, such as audio applications where the data needs to be accurately converted from an analog signal to a digital signal for encoding. It is capable of an SNR of up to 89dB, DNR of up to 82dB and a THD+N ratio of up to 87dB. The device also offers low power operation with a power dissipation as low as 230mW.

The WM8768GEDS/RV is designed with a differential input and single-ended output and features a sampled output and dual-channel support. Its 8-pin package gives the user flexible and convenient system integration, and the analog input is differential comprising inputs of +IN, -IN / CLK, CLKLF.

The main features of the WM8768GEDS/RV include:

• Multi-bit, differential ADCs and DACs
• Low power operation
• Excellent linearity and dynamic range
• SNR of up to 89 dB
• DNR of up to 82 dB
• THD+N ratio of up to 87dB
• Sampled output and dual-channel support
• 8-pin package for flexible system integration
• On-chip programmable gains

The main application of the WM8768GEDS/RV include digital audio, broadcast and cabletv systems, HSDPA/GSM/EDGE applications, multi-carrier demodulation and ISDB-T satellite systems. The device can be used in products such as MP3 players, multimedia handsets and portable audio/video recorders or players, as well as consumer audio/video and communications applications.

The working principle of the WM8768GEDS/RV is relatively simple. Its operation is based on the application of a differential signal across its input pins, which is then converted into a digital signal for use by the data processing system. The input signal is amplified by an on-chip programmable gain amplifier and then converted into a digital signal using a multi-bit delta-sigma modulator. The output of the modulator is then filtered to a single-ended output.

The WM8768GEDS/RV is a low power, high performance differential ADC/DAC converter, suitable for applications where data accuracy and power is a priority. Its multi-bit format and differential input/single-ended output make it ideal for applications such as audio applications where the data needs to be accurately converted from an analog signal to a digital signal for encoding. The device also offers low power operation and is available in standard 8-lead plastic, SOIC and TSSOP packages for a variety of system designs.
