ADS4229IRGCT is a Texas Instruments dual-channel, 12-bit analog-to-digital converter for high-speed signal acquisition, with sampling rates up to 250 MSPS per channel. It supports selectable DDR LVDS or parallel CMOS digital outputs and is supplied in the 64-pin RGC VQFN package.

Core specifications - Two analog input channels; 12-bit resolution - Sampling rate up to 250 MSPS per channel - Selectable DDR LVDS or parallel CMOS output interface - Nominal 1.8 V analog and digital supplies - 2 V peak-to-peak differential input range - Programmable gain from 0 to 6 dB and DC offset correction - 64-pin VQFN (RGC), 9 x 9 mm - Operating temperature: -40 C to +85 C

Interface and design considerations Use the TI datasheet to select the output interface and verify clocking, input drive, reference configuration, power supplies and PCB layout. The maximum 250 MSPS device rate must not be assumed for every output mode: the parallel CMOS timing specifications cover operation up to 200 MSPS. DDR LVDS is the appropriate documented interface to review for operation at 250 MSPS.

Applications Suitable design contexts include wireless communication receivers, software-defined radio, high-speed data acquisition and power-amplifier linearization. Final suitability depends on the complete analog front end, clock source and digital processing design.

Ordering and documentation The exact ordering code is ADS4229IRGCT. TI lists the T suffix as a 250-piece tape-and-reel packing option; this describes manufacturer packaging, not HONGTE stock or minimum order quantity. The linked TI ADS4229 datasheet (Rev. C) contains the ADS4229 specifications and RGC package information.
