AD8376 is an ultralow distortion IF dual VGA product released by Analog Devices. Its features include dual independent digitally controlled VGAs, bandwidth of 700 MHz (-3 dB), gain range of -4 dB to +20 dB, step size of 1 dB ± 0.2 dB, differential input and output, noise figure of 8.7 dB @ maximum gain, output IP3 of ~50 dBm at 200 MHz, output P1dB of 20 dBm at 200 MHz, dual parallel 5-bit control interface, provides constant SFDR vs. gain, power-down control, single 5 V supply operation, 32-lead, 5 mm x 5 mm LFCSP package.
The AD8376 is a dual‑channel, digitally controlled variable‑gain amplifier with a 700 MHz –3 dB bandwidth, gain range from –4 dB to +20 dB in 1 dB steps, and low noise figure (8.7 dB). It offers high output IP3 (~50 dBm at 200 MHz) and supports a single 5 V supply in a compact 32‑lead LFCSP package.
The datasheet provides detailed specifications, absolute maximum ratings, pin descriptions, typical performance curves, and ordering information. It also includes application notes for differential ADC drivers, IF sampling receivers, and instrumentation.
