FEATURES

DESCRIPTION
Low Noise, 0.5% Tolerance,
5MHz to 28MHz, Pin Congurable
Filter/ADC Driver
The LTC6601-1 is a very easy-to-use fully differential
2nd order active RC lter and driver. On-chip resistors,
capacitors, and amplier bandwidth are trimmed to provide
consistent and repeatable lter characteristics.
The lter characteristics are pin-strap congurable. 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 amplier
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.
