AD9226ARS

AD9226ARS Description

The AD9226ARS from Analog Devices Inc. is a high-performance 12-bit, 65MSPS pipelined analog-to-digital converter (ADC) designed for demanding signal-processing applications. Housed in a 28-pin SSOP package, this single-channel ADC supports both differential and single-ended inputs, offering flexibility in system design. With a 5V analog supply and a 2.85V to 5.25V digital supply, it ensures robust operation across varying power conditions. The device features a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring accurate signal capture. Although marked as obsolete, its performance characteristics make it a viable choice for legacy or specialized systems requiring high-speed, medium-resolution conversion.

AD9226ARS Features

• 12-bit resolution at 65MSPS sampling rate, ideal for precision applications.
