The LT6604-5 consists of two matched, fully differential amplifiers, each with a 4th order, 5MHz lowpass filter. The fixed frequency lowpass filter approximates a Chebyshev response. By integrating a filter and a differential amplifier, 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 significantly degrading the signal-to-noise ratio.Gain and phase are well matched between the two channels. Gain for each channel is independently programmed using two external resistors. The LT6604-5 enables level shifting by providing an adjustable output common mode voltage, making it ideal for directly interfacing to ADCs. The LT6604-5 is fully specified 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 amplifiers with integrated 2.5MHz to 20MHz lowpass filters.ApplicationsDual Differential ADC Driver and FilterSingle-Ended to Differential ConverterMatched, Dual, Differential Gain or Filter StageCommon Mode Translation of Differential SignalsHigh Speed ADC Antialiasing and DAC Smoothing in Wireless Infrastructure or Networking ApplicationsHigh Speed Test and Measurement EquipmentMedical Imaging
