n LTC6605-7 Dual Matched 7MHz Filter with Low Noise, Low Distortion Differential Amplifier DESCRIPTION
n n n n n n n Two Matched 7MHz 2nd Order Lowpass Filters with Differential Amplifiers Gain Match: ±0.35dB Max, Passband Phase Match: ±1.2° Max, Passband Single-Ended or Differential Inputs < –90dBc Distortion in Passband 2.1nV/√Hz Op Amp Noise Density Pin-Selectable Gain (0dB/12dB/14dB) Pin-Selectable Power Consumption (0.35mA/ 16.2mA/33.1mA) Rail-to-Rail Output Swing Adjustable Output Common Mode Voltage Control Buffered, Low Impedance Outputs 2.7V to 5.25V Supply Voltage Small 22-Pin 6mm × 3mm × 0.75mm DFN Package The LTC®6605-7 contains two independent, fully differential amplifiers configured as matched 2nd order lowpass filters. The f–3dB of the filters is adjustable in the range of 6.5MHz to 10MHz. The internal op amps are fully differential, feature very low noise and distortion, and are compatible with 16-bit dynamic range systems. The inputs can accept singleended or differential signals.
