AD9625BBP-2.6

Analog To Digital Converters (ADC) Overview

The AD9625BBP-2.6 is a 12-bit, single-channel analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It operates at a maximum sampling rate of 2.6 GSPS using a pipelined architecture with BiCMOS process technology. The device features a differential voltage input range of 1.2 V p-p and an internal voltage reference. Digital data is transmitted via a JESD204B interface supporting up to eight lanes. Power is supplied through separate analog and digital rails, typically requiring 1.3 V and 2.5 V. The component is housed in a 196-pin TEBGA package and is rated for industrial operation between -40°C and +85°C.
