Overview
The AD6600AST, produced by Analog Devices Inc., is a high-performance, dual-channel, gain-ranging analog-to-digital converter (ADC) with integrated Received Signal Strength Indicator (RSSI) functionality. This mixed-signal receiver chip is designed for high-speed data acquisition in complex signal processing applications. It features two input channels, each equipped with 1 GHz input amplifiers and 30 dB of automatic gain-ranging circuitry. The device samples signals at analog input frequencies up to 250 MHz and includes a 450 MHz track-and-hold stage followed by an 11-bit, 20 MSPS ADC. The AD6600AST also provides digital RSSI outputs, an A/B channel indicator, and a 2× clock output, making it highly versatile for various communication and signal processing tasks.
