Wolfson Microelectronics plc WM8181
The WM8181 is a 12-bit resolution, 2MSPS single channel image digitiser which is designed for easy interface to either CIS or CCD linear image sensors. The applied clock frequency (MCLK) equals the bit rate of the data output. The sample rate of the WM8181 can be either 1/12th or 1/16th of the applied master clock frequency.| Part No. | WM8181 |

DESCRIPTION
Data is output in serial mode. The device can be configured for either single-ended or differential input operation. In single ended input mode, a reset clamp voltage can be applied to the analogue signal, under the control of a digital signal at the CLAMP pin. The WM8181 will accept either positive or negative-going video signals at any voltage between AGND and AVDD. The ADC references are internally generated. The range of these references may be derived internally using a bandgap generator or externally using the VREFIN pin. The WM8181 is powered from either 3.3V or 5V single supplies. The device may also be powered from split 5V and 3.3V dual supplies. Typically, the WM8181 consumes 23mA supply current in normal operation. When the device is powered down, the supply current falls to less than 1µA. The WM8181 is available in a 16-pin wide-body SOIC package.FEATURES
