Description
The ADS6142 is a high performance and low power consumption 14-bit A/D converter with a sampling frequency of 65 MSPS. An internal high bandwidth sample and hold and a low jitter clock buffer help to achieve high SNR and high SFDR even at high input frequencies.
The ADS6142 features coarse and fine gain options to improve SFDR performance at lower full-scale analog input ranges.
The digital data outputs are either parallel CMOS or DDR (Double Data Rate) LVDS. Several features exist to ease data capture such as controls for output clock position and output buffer drive strength, LVDS current, and internal termination programmability.
The output interface type, gain, and other functions are programmed using a 3-wire serial interface. Alternatively, some functions are configured using dedicated parallel pins so the device powers up to the desired state.
The ADS6142 includes internal references while eliminating traditional reference pins and associated external decoupling. External reference mode is also supported.
The ADS6142 is specified over the extreme temperature range (40°C to 210°C).
