LT6350CDD#TRPBF

Overview

The LT6350CDD#TRPBF is a low noise single-ended to differential converter and ADC driver manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a gain-bandwidth product of 33 MHz and a slew rate of 48 V/µs. The device operates on supply voltages ranging from 2.7V to 12V, drawing 4.8mA at 5V. It provides high DC linearity (<±1LSB for 16-bit) and low harmonic distortion (-102dBc HD2/-97dBc HD3 at 100kHz). Packaged in an 8-lead 3mm x 3mm DFN, it supports fast settling times of 240ns.

Feature Summary

• Converts high or low impedance single-ended signals to balanced differential outputs suitable for driving SAR ADCs
• Features very low input-referred voltage noise density of 1.9nV/√Hz and current noise density of 1.1pA/√Hz
• Includes internal feedback resistors eliminating the need for external gain components in standard configurations
• Offers low power shutdown mode consuming only 60µA

Applications

• Driving 16-bit and 18-bit SAR ADCs
• Single-ended to differential conversion
• Differential line drivers

Procurement Notes

Verify the specific temperature grade suffix matches the application requirements. The C-grade variant is specified for operation between 0°C and 70°C. Ensure the tape and reel packaging aligns with automated assembly equipment specifications. Confirm that the lead-free finish meets environmental compliance standards for the target market.

Selection Notes

Select this component when high dynamic range and low noise are critical for signal integrity. The internal resistor network simplifies layout compared to discrete solutions. Consider the 33MHz bandwidth and fast settling time for high-speed data acquisition systems requiring accurate waveform reproduction without external compensation components.
