LT5554, Broadband Ultra Low Distortion 7-Bit Digitally Controlled VGA
The LT®5554 is a 7-bit digitally controlled programmable gain (PG) amplifier with 16dB gain control range.
It consists of a 50Ω input variable attenuator, followed by a high linearity variable transconductance amplifier.
The coarse 4dB input attenuator step is implemented via 2-bits of digital control
