LT6600-2.5 - Very Low Noise, Differential Amplifier And 2.5MHz Lowpass Filter
The LT6600-2.5 combines a fully Differential Amplifier with a 4th order 2.5MHz lowpass Filter approximating a Chebyshev frequency response. Most Differential Amplifiers require many precision external components to tailor gain and bandwidth. In contrast, with the LT6600-2.5 two external resistors program differential gain, and the Filters 2.5MHz cutoff frequency and passband ripple are internally set. The LT6600-2.5 also provides the necessary level shifting to set its output common mode voltage to accommodate the reference voltage requirements of A/Ds.
Using a proprietary internal architecture, the LT6600-2.5 integrates an antialiasing Filter and a Differential Amplifier driver without compromising distortion or low noise performance. At unity gain the measured in band signal-to-noise ratio is an impressive 86dB. At higher gains the input referred noise decreases so the part CAN process smaller input differential signals without significantly degrading the output signa 4fc l-to-noise ratio.
The LT6600-2.5 also features low voltage operation. The differential design provides outstanding performance for a 4VP-P signal level while the part operates with a single 3V supply. The LT6600-2.5 is available in SO-8 and DFN-12 packages.
