ADS62P43IRGCR

The ADS62P43IRGCR is a dual channel 14-bit analog-to-digital converter (ADC) from Texas Instruments, part of the ADS62P4X family. It operates at a maximum sampling rate of 80 MSPS and uses a pipelined architecture with differential inputs. The device supports both internal and external references and offers DDR LVDS and parallel CMOS output interfaces.

Key electrical specifications include a supply voltage range of 1.65V to 3.6V, typical analog power consumption of 594 mW, and an operating temperature range of -40°C to 85°C. The ADC achieves a typical SFDR of 93 dBc at 10 MHz input and SINAD of 74.6 dBFS. It features 95 dB crosstalk between channels and includes coarse gain (3.5 dB) and programmable fine gain (0 to 6 dB in 0.05 dB steps) for SNR/SFDR trade-offs.

The ADS62P43IRGCR incorporates a digital processing block with offset correction, fine gain correction, decimation by 2/4/8, and built-in or custom programmable 24-tap low-pass, high-pass, and band-pass filters. It supports sine, LVPECL, LVDS, and LVCMOS clock inputs with a duty cycle stabilizer. The device is designed for simultaneous sampling.

The ADC is housed in a 64-VFQFN exposed pad package (64-VQFN 9x9 mm) for surface mount assembly. The lead finish is NiPdAuAg. It is RoHS3 and REACH compliant (unverified). Typical applications include wireless communications infrastructure, medical imaging, radar systems, and test and measurement instrumentation.
