Description
The AT001D3-24 is an IC FET digital attenuator
consisting of three monolithic attenuators with LSB of
4 dB and a total attenuation of 28 dB with all attenuators
connected. Attenuator bits are switched with -5 and 0 V.
The attenuator is packaged in the plastic 14 lead surface
mount package for low cost commercial cellular radio
applications.
Operating Characteristics at 25°C (0, -5 V)
SOIC-14
1. All measurements made in a 50
system, unless otherwise specified.
2. DC = 300 kHz.
3. Insertion loss changes by 0.003 dB/°C.
4. Attenuation referenced to insertion loss.
5. Video feedthru measured with 1 ns risetime pulse and 500 MHz bandwidth.
