Overview
The LTC6400CUD-20#PBF is a high-speed differential amplifier designed for processing signals from DC to 300MHz. It features a fixed gain of 10V/V (20dB) and a 1.8GHz –3dB bandwidth. The device operates on a supply voltage between 2.85V and 3.5V with a typical current of 90mA. Key electrical parameters include a total input noise of 2.1nV/√Hz, a noise figure of 6.2dB, and an equivalent output IP3 of 51dBm at 70MHz. It utilizes a 16-lead 3mm × 3mm QFN package.
Feature Summary
- Fixed internal gain of 10V/V (20dB) with 200Ω differential input impedance
- Adjustable output common mode voltage via external VOCM pin
- Integrated low-pass filter outputs for enhanced signal integrity
- Capable of single-ended to differential conversion without baluns
Applications
- Differential ADC Driver
- IF Sampling Receivers
- SAW Filter Interfacing
Procurement Notes
Verify the specific suffix 'C' indicates the commercial temperature range (0°C to 70°C). Confirm the '#PBF' designation corresponds to lead-free packaging and RoHS compliance. Ensure the part number matches the exact gain version required for the design specifications.
Selection Notes
Select this component when driving 12-bit to 16-bit ADCs directly. It eliminates the need for external transformers or AC-coupling capacitors in many configurations. Consider the LTC6401 family if lower power consumption is prioritized over linearity at higher frequencies.
Part Context
This device belongs to the LTC6400 series of fully differential amplifiers. It is specifically engineered to interface with high-speed analog-to-digital converters. The series offers various gain options and includes a lower-power variant known as the LTC6401.

FAQ
How is the output common mode voltage controlled?
The output common mode voltage is set by the VOCM pin, which allows adjustment within a range of 1V to 1.6V.
Can the LTC6400-20 operate with AC coupling?
Yes, the device supports both DC-coupled and AC-coupled operation at the inputs and outputs.
