Description
M/A-COM’s AT90-1233 is a GaAs FET 4-Bit digital
attenuator with integral driver. Step size is 2 dB providing
a 30 dB attenuation range. This device is in an FQFP-N
plastic surface mount package. The AT90-1233 is suited
for single supply applications where accuracy, fast speed,
low power consumption and low costs are required.
