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 can be either single-ended, single-ended with offset, or differential. 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 VREFB and VREFT 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.

Frequently Asked Questions
What package options are available for the THS1230?
It is available in 28-pin TSSOP (PW) and SOIC (DW) packages.
How do I enable or disable the output of the THS1230?
Set the OE (Output Enable) pin low to enable the outputs, and set it high to disable them.
What is the operating supply voltage for the THS1230?
It operates from a 3.3-V supply.
Can I use an external reference voltage with the THS1230?
Yes, set the EXTREF pin high to bypass the internal reference and use an external one.
