Description
M/A-COM’s AT65-0233 is a GaAs FET 4-bit digital attenuator
with a 2.0 dB minimum step size and a 30 dB total attenuation
range. This device is in a SOIC-16 plastic surface mount package.
The AT65-0233 is ideally suited for use where accuracy, fast
speed, very low power consumption and low costs are required.
Typical applications include dynamic range setting in precision
receiver circuits and other gain/leveling control circuits.
