Description

The AD9229 is a 50 or 65 MSPS quad 12-bit, analogtodigital converter with serial LVDS outputs. An onchip trackandhold circuit is designed for low cost, low power, small size and ease of use.

The AD9229 is a quad 12-bit monolithic sampling analogtodigital converter with an onchip trackandhold circuit and is designed for low cost, low power, small size and ease of use. The product operates up to a 65 MSPS conversion rate and is optimized for outstanding dynamic performance where a small package size is critical. The ADC requires a single+3.0 V power supply and a TTL/CMOS compatible sample rate clock for full performance operation. No external reference or driver components are required for many applications. A separate output power supply pin supports LVDS compatible serial digital output levels.

The ADC automatically multiplies up the sample rate clock for the appropriate LVDS serial data rate. An MSB trigger is provided to signal a new output byte. Power down is supported and consumes less than 3mW when enabled. Fabricated on an advanced CMOS process, the AD9229 is available in a 48-LFCSP package specified over the industrial temperature range (40°C to +85°C).
