AD603 - Variable Gain Amplifier

Analog Devices

Datasheet Details

Data Sheet Low Noise, 90 MHz Variable Gain Amplifier AD603.

Linear-in-dB gain control Pin-programmable gain ranges.
11 dB to +31 dB with 90 MHz bandwidth 9 dB to 51 dB with 9 MHz bandwidth Any intermediate range, for example.
1 dB to +41 dB with 30 MHz bandwidth Bandwidth independent of variable gain 1.3 nV/√Hz input noise spectral density ±0.5 dB typical gain accuracy The decibel gain is linear in dB, accurately calibrated, and stable over temperature and supply. The gain is controlled at a high impedance (50 MΩ), low bias (200 nA) diff.
