Description
The LTC6601-2 is a low power, low distortion, very easy-to-use fully differential 2nd order active broadband 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 27MHz. Gain is pin-strap programmable between –17dB and +17dB.
A three-state BIAS pin is provided to adjust amplifier power consumption. Select between low power (50% power reduction), high performance and standby modes with the BIAS pin.
The LTC6601 family comes in two options which trade off distortion and noise. The LTC6601-2 offers the lowest distortion at high frequencies. The LTC6601-1 is configured for lowest noise. Both are available in pin-compatible packages.
The LTC6601-2 is available in a compact 4mm × 4mm 20-pin leadless QFN package.
