Description

The THS1041 is a CMOS, low power, 10-bit, 40 MSPS analog-to-digital converter (ADC) that operates from a single 3-V supply. It has been designed to give circuit developers flexibility. The analog input to the THS1041 can be either single-ended or differential.

THS1041 has a built-in clamp amplifier whose clamp input level can be driven 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 signals. The THS1041 provides a wide selection of voltage

references to match the user's design requirements. For more design flexibility, the internal reference of THS1041 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 indicates any out-of-range condition in THS1041's input signal. The format of the digital output can be coded in either unsigned binary or 2s complement.

The speed, resolution, and single-supply operation of the THS1041 are suited to applications in set-top-box (STB), video, multimedia, imaging, high-speed acquisition, and communications. The built-in clamp function allows dc restoration of a video signal and is suitable for video applications. 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 allows the THS1041 to be applied in both imaging and communications systems.

The THS1041C is characterized for operation from 0°C to 70°C, while the THS1041I is characterized for operation from 40°C to 85°C.
