Description

M/A-COM's AT90-0283 is a GaAs FET 5-bit digital

attenuator with integral TTL driver. Step size is 0.5

dB providing a 15.5 dB total attenuation range. This

device is in an FQFP-N plastic surface mount

package. The AT90- 0283 is ideally suited for use

where accuracy, fast speed, very low power

consumption and low costs are required.
