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_REFB and V_REFT allows 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.
