ec78ec78ic606a.jpge_arrows.jpgSupertex today introduced the MD3880, a four-channel, low-noise amplifier (LNA) with a variable gain amplifier (VGA). The IC features very low current (0.35 pA/sqrtHz) and voltage (0.74 nV/sqrtHz) noises and linear-in-dB continuous variable gain control. The MD3880 has fully differential inputs and outputs that provide a high common-mode noise rejection ratio. The IC also has a programmable gain amplifier (PGA) with four discrete gain settings. The output of the LNA is fed directly into the VGA, eliminating the need for an external coupling capacitor. The part is green and RoHS compliant. Pricing is $12 each for the MD3880B2-G in 1K quantities.
