Description
The AK802D4-24 is an IC FET digital attenuator
consisting of four monolithic attenuators with an LSB of
1 dB and a total attenuation of 15 dB with all attenuators
connected.
The device has integral drivers for each bit requiring less
than 4 mA per bit. DC supply voltages of +5 and -5.6 V
are required.
The attenuator is packaged in a 14 lead plastic SOIC.
