LTC6401-26

1.6GHz Low Noise,

Low Distortion Differential

ADC Driver for DC-140MHz

FEATURES

DESCRIPTION

The LTC^®6401-26 is a high-speed differential ampliﬁer

targeted at processing signals from DC to 140MHz. The

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

16-bitADCswithlownoiseandlowdistortion,butcanalso

be used as a general-purpose broadband gain block.

■

1.6GHz –3dB Bandwidth

■

Fixed Gain of 20V/V (26dB)

■

–85dBc IMD3 at 70MHz (Equivalent OIP3 = 46.5dBm)

■

–72dBc IMD3 at 140MHz (Equivalent OIP3 = 40dBm)

■

1nV/√Hz Internal Op Amp Noise

■

1.5nV/√Hz Total Input Referred Noise

The LTC6401-26 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 of transformers or AC-coupling ca-

pacitors in many applications. The gain is internally ﬁxed

at 26dB (20V/V).

■

Differential Inputs and Outputs

■

50Ω Input Impedance

■

2.85V to 3.5V Supply Voltage

■

45mA Supply Current (135mW)

■

1V to 1.6V Output Common Mode, Adjustable

■

The LTC6401-26 saves space and power compared to

alternative solutions using IF gain blocks and transform-

ers. The LTC6401-26 is packaged in a compact 16-lead

3mm × 3mm QFN package and operates over the –40°C

to 85°C temperature range.
