Overview
The ADC08D500CIYB from Texas Instruments is a dual, low power, high performance CMOS analog-to-digital converter. It digitizes signals to 8 bits resolution at sampling rates up to 500 MSPS. This device operates from a single 1.9V ±0.1V supply, consuming a typical 1.4 Watts at 500 MSPS. The ADC08D500CIYB features a unique folding and interpolating architecture, a fully differential comparator design, and an innovative internal sample-and-hold amplifier, ensuring a very flat response of all dynamic parameters beyond Nyquist. It achieves a high 7.5 ENOB with a 250 MHz input signal and a 500 MHz sample rate, along with a bit error rate of 10^-18. The device is available in a 128-lead, thermally enhanced exposed pad HLQFP package and operates over the Industrial temperature range of -40°C to +85°C.
