description The THS1031 is a CMOS, low power, 10-bit, 30 MSPS analog-to-digital converter (ADC) that can operate with a supply range from 2.7 V to 3.3 V. The THS1031 has been designed to give circuit developers more flexibility. The analog input to the THS1031 can be either single-ended or differential. This device has a built-in clamp amplifier whose clamp input level can be selected from an external dc source or from an internal high-precision 10-bit digital clamp level programmable via an internal CLAMP register. A 3-bit PGA is included to maintain SNR for small signal. The THS1031 provides a wide selection of voltage reference to match the user’s design requirements. For more design flexibility, the internal reference can be bypassed to use an external reference to suit the dc accuracy and temperature drift requirements of the application. The out-of-range output is used to monitor any out-of-range condition in THS1031’s input range. The format of digital output can be coded in either straight binary or 2s complement. The speed, resolution, and single-supply operation of the THS1031 are suited for applications in set-top-box (STB), video, multimedia, imaging, high-speed acquisition, and communications. The built-in clamp function allows dc restoration of video signal and is suitable for video application. The speed and resolution ideally suit charge-couple device (CCD) input systems such as color scanners, digital copiers, digital cameras, and camcorders. A wide input voltage range between REFBS and REFTS allows the THS1031 to be applied in both imaging and communications systems The THS1031I is characterized for operation from –40°C to 85°C.
