Linear Technology LT6600-2.5

the LT6600-2.5, two external resistors program differential gain, and the ﬁlter’s 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.

DESCRIPTION

The LT®6600-2.5 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 tail or gain and bandwidth. In contrast, with At unity gain the measured in band signalto-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 signal-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. For similar devices with higher cutoff frequency, refer to the LT6600-5, LT6600-10, LT6600-15 and LT6600-20 data sheets. ±0.6dB (Max) Ripple 4th Order Lowpass Filter with 2.5MHz Cutoff Programmable Differenti...
