Overview
The LTC6403HUD-1#PBF is a precision, low noise, low distortion fully differential input/output amplifier optimized for single supply operation between 2.7V and 5.25V. It features a 200MHz gain-bandwidth product, 2.8nV/√Hz input-referred voltage noise density, and 10.8mA supply current. The device includes unfiltered outputs (+OUT, –OUT) and filtered outputs (+OUTF, –OUTF) with a built-in 44.2MHz single-pole lowpass filter. It operates over a temperature range of –40°C to 125°C in a 16-pin 3mm × 3mm QFN package.
Feature Summary
- Fully differential input and output architecture
- Built-in clamp for fast overdrive recovery
- Adjustable output common mode voltage
- Rail-to-rail output swing capability
Applications
- Differential input A/D converter driver
- Single-ended to differential conversion and amplification
- Common mode level translation
- Low voltage, low noise signal processing
Procurement Notes
Verify the specific suffix 'HUD' corresponds to the extended industrial temperature range of –40°C to 125°C. Confirm the '#PBF' designation indicates lead-free finish compliance. Ensure the 16-lead QFN package dimensions match the required PCB footprint. Validate that the component meets RoHS standards as specified by Analog Devices.
Selection Notes
Select this part when driving high-resolution ADCs requiring low noise and wide bandwidth. Consider the 200MHz GBW for high-frequency signal conditioning. Evaluate the 10.8mA supply current against power constraints. Use the filtered outputs if inherent anti-aliasing filtering near 44.2MHz is beneficial.
Part Context
This component belongs to the LTC6403-1 family of fully differential amplifiers. It shares core specifications with the LTC6403IUD-1#PBF but offers an extended operating temperature range up to 125°C. The device is designed to replace single-ended amplifiers in differential architectures to improve dynamic range and reject common-mode noise.
Replacement Considerations

FAQ
What is the function of the +OUTF and –OUTF pins?
These pins provide filtered versions of the main outputs, featuring a built-in 44.2MHz differential single-pole lowpass filter.
How is the shutdown mode activated?
The SHDN pin must be pulled at least 2.1V below the positive supply voltage to enter the low-power shutdown state.
