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.ApplicationsDifferential A/D Converter DriverAntialiasing/Reconstruction FilterSingle-Ended to Differential Conversion/AmpliﬁcationLow Voltage, Low Noise, Differential Signal ProcessingCommon Mode Voltage TranslationPortable Instrumentation
