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).

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
