8-bit ADCs

27 April 2011 Analogue, Mixed Signal, LSI

Analog Devices released two new 8-bit, low-noise ADCs (analog-to-digital converters) designed for instrumentation and communications applications. Both devices use a pipeline architecture and consume only 310 mW of power.

The AD9284 is a dual, 250 MSps ADC while the AD9286 offers a single 500 MSps channel. They feature high SNR (signal-to-noise ratio) of 49,3 dBFS and allow for a wide dynamic signal range with SFDR (spurious-free dynamic range) performance of 65 dBc. Both parts operate from a single 1,8 V supply, and the AD9286 features on-chip simultaneous or interleaved clocking.

Applications for these components include battery-powered instruments, handheld scope meters and digital oscilloscopes.
