LTC6601-1 - Low Noise, 0.5% Tolerance, 5MHz to 28MHz, Pin Configurable Filter/ADC Driver

The LTC6601-1 is a very easy-to-use fully differential 2nd order active RC filter and driver. On-chip resistors, capacitors, and amplifier bandwidth are trimmed to provide consistent and repeatable filter characteristics. The filter characteristics are pin-strap configurable. Cutoff frequencies range from 5MHz to 28MHz. Gain is pin-strap programmable between –17dB and +17dB. A three-state BIAS pin is provided to adjust amplifier power consumption. Select between high performance, low power (50% power reduction), and standby modes with the BIAS pin. The LTC6601-1 is available in a compact 4mm × 4mm 16-pin leadless QFN package.
