DESCRIPTION

The THS1230 is a CMOS, low-power, 12-bit, 30 MSPS analog-to-digital converter (ADC) that operates with a

3.3-V supply. The THS1230 gives circuit developers complete flexibility. The analog input to the THS1230 is

differential with a gain of 0.5 for Mode 2 and 1.0 for Mode 1. The THS1230 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 is used to monitor any out-of-range condition in the THS1230's input range.

The speed, resolution, and single-supply operation of the THS1230 are suited for applications in set top box

(STB), video, multimedia, high-speed acquisition, and communications. The speed and resolution ideally suit

charge-couple device (CCD) input systems such as digital copiers, digital cameras, and camcorders. The wide

input voltage range between V_REFBand V_REFTallows the THS1230 to be designed into multiple systems.

The THS1230C is characterized for operation from 0°C to 70°C. The THS1230I is characterized for operation

from –40°C to 85°C.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
