ADS61JB23IRHAR

Analog To Digital Converters (ADC) Overview

The ADS61JB23IRHAR is a dual-channel, high-speed analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 250 MSPS and supports an input bandwidth up to 1.2 GHz. The device features a differential input architecture and utilizes a serial LVDS interface for data output. It requires a single +3.3V power supply and includes internal reference and clock buffers. Key performance metrics include a typical noise figure of 4.8 dB and an SFDR of 72 dBc at 100 MHz input frequency. The component is housed in a 48-pin VQFN package suitable for compact designs.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RHAR' against the official datasheet to confirm package type, tape-and-reel quantity, and temperature grade. Ensure compatibility with required I/O voltages and clocking schemes before integration. Check for moisture sensitivity level requirements during storage and handling.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and high input bandwidth are critical. Compare against single-channel alternatives if channel count can be reduced. Evaluate power consumption constraints relative to the 3.3V supply requirement. Consider board space limitations imposed by the VQFN-48 package footprint.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS61JBxx family of high-performance ADCs designed for demanding RF applications. It shares architectural similarities with other members in the series but differs in sampling rates and specific interface configurations. The family targets applications requiring low latency and high dynamic range in a small form factor.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades within the ADS61JBxx family. Verify electrical parameter equivalence for any cross-family replacements. Confirm that alternative parts support the same serial LVDS interface timing specifications.
