LTC6401-8

2.2GHz Low Noise, Low

Distortion Differential ADC

Driver for DC-140MHz

FEATURES

DESCRIPTION

The LTC^®6401-8 is a high-speed differential ampliﬁer tar-

geted at processing signals from DC to 140MHz. The part

has been speciﬁcally designed to drive 12-, 14- and 16-bit

ADCs with low noise and low distortion, but can also be

used as a general-purpose broadband gain block.

■

2.2GHz –3dB Bandwidth

■

Fixed Gain of 2.5V/V (8dB)

■

–92dBc IMD3 at 70MHz (Equivalent OIP3 = 50dBm)

■

–80.5dBc IMD3 at 140MHz (Equivalent OIP3 = 44dBm)

■

1nV/√Hz Internal Op Amp Noise

■

12.1dB Noise Figure

The LTC6401-8 is easy to use, with minimal support cir-

cuitry 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 8dB (2.5V/V).

■

Differential Inputs and Outputs

■

400Ω Input Impedance

■

2.85V to 3.5V Supply Voltage

■

45mA Supply Current (135mW)

■

1V to 1.6V Output Common Mode, Adjustable

■

DC- or AC-Coupled Operation

Max Differential Output Swing 4.6V

■

The LTC6401-8 saves space and power compared to al-

ternative solutions using IF gain blocks and transformers.

The LTC6401-8 is packaged in a compact 16-lead 3mm ×

3mm QFN package and operates over the –40°C to 85°C

temperature range.
