LT6604-10

The LT®6604-10 consists of two matched, fully differential amplifi ers, each with a 4th order, 10MHz lowpass fi lter. The fi xed frequency lowpass fi lter approximates a Chebyshev response. By integrating a fi lter and a differential amplifi er, distortion and noise are made exceptionally low. At unity gain, the measured in band signal-to-noise ratio is an impressive 82dB. At higher gains, the input referred noise decreases, allowing the part to process smaller input differential signals without signifi cantly degrading the signal-to-noise ratio.

Gain and phase are highly matched between the two channels. Gain for each channel is independently programmed using two external resistors. The LT6604-10 enables level shifting by providing an adjustable output common mode voltage, making it ideal for directly interfacing to ADCs. The LT6604-10 is fully specifi ed for 3V operation. The differential design enables outstanding performance at a 2VP-P signal level for a single 3V supply. See the back page of this datasheet for a complete list of related single and dual differential amplifi ers with integrated 2.5MHz to 20MHz lowpass fi lters.
