ADC3424IRTQT

The ADC3424IRTQT is a quad-channel 12-bit analog-to-digital converter (ADC) from Texas Instruments, capable of sampling rates up to 125 MSPS. It employs a pipelined architecture and accepts differential analog inputs. The two-wire serial LVDS interface serializes each channel's 12-bit data over two LVDS pairs, reducing the number of interface lines and enabling high system integration density. The device operates from a single 1.8 V supply.

The ADC342x family, which includes the ADC3424, supports sample rates from 25 MSPS to 125 MSPS. Key performance specifications include an SNR of 70.7 dB, SFDR of 94 dB, analog input bandwidth of 540 MHz, and typical total power consumption of 391 mW (98 mW per channel at 125 MSPS). An input clock buffer with divide-by-1, -2, and -4 options and a SYSREF input enable flexible system clock design and multi-chip synchronization.

The device is packaged in a 56-pin VQFN (RTQ) package measuring 8 mm × 8 mm. It is rated for operation from -40°C to +85°C and is pin-to-pin compatible with the 14-bit version of the ADC342x family. These features support demanding high input frequency signals with large dynamic range requirements while maintaining low power consumption.
