Product Details

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.


  • Differential Input A/D Converter Driver
  • Antialiasing/Reconstruction Filter
  • Single-Ended to Differential Conversion/Amplification
  • Low Voltage, Low Noise, Differential Signal Processing
