THS1031IDW

Product Summary

The THS1031IDW is a CMOS, low power, 10-bit, 30 MSPS analog-to-digital converter (ADC) that can operate with a supply range from 2.7 V to 3.3 V. The THS1031IDW has been designed to give circuit developers more flexibility. The analog input to the THS1031IDW can be either single-ended or differential. This device has a built-in clamp amplifier whose clamp input level can be selected 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 signal. The THS1031IDW provides a wide selection of voltage reference 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 THS1031IDW’s input range. The format of digital output can be coded in either straight binary or 2s complement.
