LTC6400-14

2.4GHz Low Noise, Low

Distortion Differential ADC

Driver for 300MHz IF

FEATURES

DESCRIPTION

The LTC^®6400-14 is a high-speed differential ampliﬁer

targeted at processing signals from DC to 300MHz. The

part has been speciﬁcally designed to drive 12-, 14- and

16-bitADCswithlownoiseandlowdistortion,butcanalso

be used as a general-purpose broadband gain block.

2.4GHz –3dB Bandwidth

Fixed Gain of 5V/V (14dB)

–97dBc IMD3 at 70MHz (Equivalent OIP3 = 52.4dBm)

–66dBc IMD3 at 300MHz (Equivalent OIP3 = 36.9dBm)

1.1nV/√Hz Internal Op Amp Noise

2.5nV/√Hz Total Input Noise

The LTC6400-14 is easy to use, with minimal support

circuitry required. The output common mode voltage is

set using an external pin, independent of the inputs, which

eliminates the need for transformers or AC-coupling ca-

pacitors in many applications. The gain is internally ﬁxed

at 14dB (5V/V).
