ADS4245IRGC25

Analog To Digital Converters (ADC) Overview

The ADS4245IRGC25 is a dual-channel, 14-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at sampling rates up to 160 MSPS and functions on a single 1.8V supply. The device features an ultralow-power architecture with total power consumption of 332mW at maximum speed. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 71.4 dBFS at 170MHz input frequency and a Spurious-Free Dynamic Range (SFDR) of 88dBc. It supports both parallel CMOS and Double Data Rate (DDR) LVDS digital output interfaces within a compact QFN-64 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as production data indicates this specific part number may be discontinued or subject to availability constraints. Confirm the package designator RGC corresponds to the QFN-64 PowerPAD variant. Ensure compliance with RoHS standards and check for moisture sensitivity level requirements during storage and handling.

Analog To Digital Converters (ADC) Selection Notes

Select the ADS4245IRGC25 for multi-carrier, wide-bandwidth applications requiring high linearity and low power. Compare against the ADS4246 if higher sampling speeds are needed, or the ADS4242 for lower power at reduced speeds. Ensure the system supports the required 1.8V analog and digital supplies and accommodates the differential input common-mode voltage of 0.95V.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS42xx family, which serves as a low-speed variant of the ultralow-power ADC series. It is pin-compatible with the previous generation ADS62P49 family, facilitating migration, though supply voltages and pin functions differ. The ADS4245 specifically targets the 125MSPS to 160MSPS range within the 14-bit segment of this portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS4246 and ADS4242 are direct family members with identical pinouts but different sampling rate specifications. Migration from the ADS62P49 family requires attention to changes in AVDD voltage (3.3V to 1.8V) and floating pins 38, 39, 58, and 59.
