DESCRIPTION
Dual Matched 14MHz Filter
with Low Noise, Low Distortion
Differential Amplier
The LTC6605-14 contains two independent, fully differ-
ential ampliers congured as matched 2nd order 14MHz
lowpass lters. The f–3dB of the lters is adjustable in the
range of 12.4MHz to 20MHz and 25MHz.
The internal op amps are fully differential, feature very
low noise and distortion, and are compatible with 16-bit
dynamic range systems. The inputs can accept single-
ended or differential signals. An input pin is provided
for each amplier to set the common mode level of the
differential outputs.
Internal laser-trimmed resistors and capacitors determine
a precise, very well matched (in gain and phase) 14MHz
2nd order lter response. A single optional external re-
sistor per channel can tailor the frequency response for
each amplier.
Three-state BIAS pins determine each amplier’s power
consumption, allowing a choice between shutdown, me-
dium power or full power.
The LTC6605-14 is available in a compact 6mm × 3mm
22-pin leadless DFN package and operates over a –40°C
to 85°C temperature range.
