Overview

Product Details

  The CBM08AD1500 is a dual, low power, high performance CMOS analog-to-digital converter that digitizes signals to 8 Bits resolution at sample rates up to 1.7 GSPS. Consuming a typical 1.8 Watts at 1.5 GSPS from a single 1.9 Volt supply, this device is ensured to have no missing codes over the full operating temperature range. The unique folding and interpolating architecture, the fully differential comparator design, the innovative design of the internal sample-and-hold amplifier and the self-calibration scheme enable a very flat response of all dynamic parameters beyond Nyquist, producing a high 7.25 ENOB with a 748 MHz input signal and a 1.5 GHz sample rate while providing a 10-18 C.E.R. Output formatting is binary and the LVDS digital outputs are compatible with IEEE 1596.3-1996, with the exception of an adjustable common mode voltage between 0.8V and 1.2V.
