ADS7800JU/1K

ADS7800JU/1K Description

The ADS7800JU/1K from Texas Instruments is a high-performance, 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for precision data acquisition systems. Packaged in a 24-pin SOIC and supplied in tape & reel (TR), this ADC integrates a single-channel, single-ended input with a 333kSPS sampling rate, making it ideal for high-speed signal processing. The device operates on a 5V digital supply and features an internal reference, simplifying system design while ensuring accuracy. With a 1:1 sample-and-hold (S/H) to ADC ratio, it delivers consistent performance in dynamic applications. The ADS7800JU/1K is ROHS3 compliant and REACH unaffected, meeting stringent environmental standards.
