AD9253BCPZRL7-80

四通道，14位， 80 MSPS / 105 MSPS / 125 MSPS Quad, 14-Bit, 80 MSPS/105 MSPS/125 MSPS

GENERAL DESCRIPTION

The AD9253 is a quad, 14-bit, 80 MSPS/105 MSPS/125 MSPS analog-to-digital converter ADC with an on-chip sample and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 125 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

The ADC requires a single 1.8 V power supply and LVPECL-/CMOS-/LVDS-compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications.
