ADS6122IRHBT

ADS6122IRHBT Description

The ADS6122IRHBT from Texas Instruments is a high-performance 12-bit pipelined analog-to-digital converter (ADC) designed for demanding applications requiring high-speed signal acquisition. Operating at a 65 MSPS sampling rate, it delivers precision conversion with differential input support, ensuring robust noise immunity. The device features a 1:1 sample-and-hold (S/H) to ADC ratio, optimizing signal integrity. With dual supply voltages (3V–3.6V analog, 1.65V–3.6V digital), it offers flexibility in mixed-voltage systems. Packaged in a 32-VQFN (5x5mm) tape-and-reel format, it is ideal for space-constrained designs. The internal reference simplifies system design, while its RoHS3 compliance and REACH unaffected status ensure environmental regulatory adherence.
