Overview
The ADC08D1520CIYB/NOPB, produced by Texas Instruments, is a low-power, high-performance CMOS analog-to-digital converter (ADC). This device is part of the ADC08D1500 platform and offers enhanced features compared to its predecessor. It is designed to digitize signals to 8 bits of resolution at sample rates up to 1.7 GSPS. The ADC08D1520 features a unique folding and interpolating architecture, a fully differential comparator design, and an innovative internal sample-and-hold amplifier, ensuring high dynamic performance. It operates on a single 1.9V supply and consumes a typical 1.6 Watts in non-demultiplex mode at 1.0 GSPS, with a power-down mode consuming only 3.5 mW.
