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

The THS1230C is characterized for operation from 0

°C to 70°C. The THS1230I is characterized for operation

from –40

°C to 85°C.
