What are the key features of LTC6406IMS8E#PBF?
- 800 MHz gain-bandwidth product enabling high-speed differential signal amplification for ADC driving up to hundreds of MHz
- Rail-to-rail input capability with 65 dB typical CMRR allowing full common-mode signal rejection across the supply range
- Low input offset voltage maximum of 3.5 mV suitable for precision differential signal conditioning without external trimming
- Compact MSOP-8 package with voltage-feedback architecture and integrated frequency compensation for stable closed-loop designs
What is LTC6406IMS8E#PBF used for?
The LTC6406IMS8E#PBF differential amplifier is primarily used as an ADC driver to convert single-ended signals to differential outputs required by high-speed pipeline and SAR ADCs operating at sampling rates of 10 MSPS to 200 MSPS. Its 800 MHz bandwidth ensures minimal signal attenuation and phase distortion up to the Nyquist frequency of fast ADC front-ends in software-defined radios, spectrum analyzers, and communications infrastructure equipment. Medical imaging systems and test and measurement instruments also use this device for its combination of low noise, rail-to-rail input swing, and differential output capability.

Frequently Asked Questions
At what signal frequencies is the LTC6406IMS8E#PBF most effective as an ADC driver?
The LTC6406IMS8E#PBF provides 800 MHz of gain-bandwidth product, making it effective as an ADC driver for input signal frequencies from DC up to approximately 200 MHz with a gain of 4 (+12 dB). At unity gain, the -3 dB bandwidth is near 800 MHz, and for typical ADC driver applications at a closed-loop gain of 2, the -3 dB frequency is approximately 400 MHz, covering most pipeline ADCs sampling at 100 MSPS to 500 MSPS.
How does the rail-to-rail input of LTC6406IMS8E#PBF benefit single-supply ADC interface circuits?
The LTC6406IMS8E#PBF's rail-to-rail input allows the common-mode input voltage to range from 0V to VCC on a single 3.3V or 5V supply, eliminating the need for a negative supply rail in signal-conditioning front-ends. This is especially useful when interfacing with single-ended sensors or DAC outputs that swing close to ground, as the amplifier can accept and amplify those signals without saturation, maintaining 65 dB of CMRR rejection throughout the input range.
What noise performance does the LTC6406IMS8E#PBF offer for communication receiver signal chains?
As a low-noise differential amplifier, the LTC6406IMS8E#PBF is designed with a voltage noise density in the range of 1 nV/√Hz to 5 nV/√Hz at high frequencies, keeping the noise figure of the ADC driver stage below 20 dB in a 50 Ω system at 100 MHz. This performance level is acceptable for intermediate-frequency signal chains in LTE and cable modem receivers where the ADC driver noise contribution must remain well below the signal quantization noise floor.
What is the input offset voltage of the LTC6406IMS8E#PBF and when does it matter for a measurement system?
The LTC6406IMS8E#PBF has a maximum input offset voltage of 3.5 mV (3500 µV). In a DC-coupled measurement system with a 3.3V ADC reference and 12-bit resolution (0.8 mV per LSB), a 3.5 mV offset represents approximately 4 LSBs of systematic error. For applications requiring sub-LSB DC accuracy, external offset trimming or a lower-offset amplifier should be considered, while for AC-coupled communication channels the 3.5 mV offset is inconsequential.
