Overview
The AD9484BCPZ-500 is an 8-bit, monolithic, sampling analog-to-digital converter (ADC) produced by Analog Devices Inc. This ADC is optimized for high performance, low power consumption, and ease of use. It operates at a conversion rate of up to 500 million samples per second (MSPS) and is designed for outstanding dynamic performance in wideband carrier and broadband systems. The device includes all necessary functions such as a sample-and-hold and voltage reference on the chip, providing a complete signal conversion solution. It is fabricated on an advanced BiCMOS process and is available in a 56-lead Lead Frame Chip Scale Package (LFCSP), specified over the industrial temperature range of −40°C to +85°C.
