LTC6605-14

Dual Matched 14MHz Filter

with Low Noise, Low Distortion

Differential Ampliﬁer

FEATURES

DESCRIPTION

The LTC^®6605-14 contains two independent, fully differ-

ential ampliﬁers conﬁgured as matched 2nd order 14MHz

Two Matched 14MHz 2nd Order Lowpass Filters

with Differential Ampliﬁers

Gain Match: ±±.2ꢀdꢁ Maꢂ, ꢃassꢄand

ꢃhase Match: ±1.1ꢅ Maꢂ, ꢃassꢄand

Single-Ended or Differential Inputs

lowpass ﬁlters. The f

of the ﬁlters is adjustable in the

–3dB

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 ampliﬁer to set the common mode level of the

differential outputs.

Rail-to-Rail Output Swing

Internallaser-trimmedresistorsandcapacitorsdetermine

a precise, very well matched (in gain and phase) 14MHz

2nd order ﬁlter response. A single optional external re-

sistor per channel can tailor the frequency response for

each ampliﬁer.

Adjustable Output Common Mode Voltage Control

Buffered, Low Impedance Outputs

2.7V to 5.25V Supply Voltage

Small 22-Pin 6mm × 3mm × 0.75mm DFN Package

Three-state BIAS pins determine each ampliﬁer’s power

consumption, allowing a choice between shutdown, me-

dium power or full power.

APPLICATIONS

Broadband Wireless ADC Driver/Filter

Antialiasing Filter

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.
