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 3 V to 5.5 V. The THS1031 has been designed to give circuit developers 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 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 THS1031 provides a wide selection of voltage references 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 indicates any
out-of-range condition in THS1031’s input signal. The format of digital output can be coded in either unsigned
binary or 2s complement.
The speed, resolution, and single-supply operation of the THS1031 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 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 between REFBS and REFTS allows the THS1031 to be applied in both
imaging and communications systems.
The THS1031C is characterized for operation from 0
°C to 70°C, while the THS1031I is characterized for
operation from –40
°C to 85°C.
