Key Features
- 35 MHz 3dB bandwidth enabling high-speed differential signal conditioning up to ADC Nyquist rates
- 112 dB typical CMRR (85 dB minimum) for superior rejection of common-mode noise on differential signal paths
- Ultra-low 0.1 µA maximum input bias current minimizing error in high-impedance sensor interfaces
- Precision voltage-feedback architecture in compact MSOP-8 package for space-efficient ADC driver designs
Applications
The LTC6363IMS8-2 is used as a precision ADC driver in data acquisition systems, industrial measurement instruments, and medical diagnostic equipment where a differential signal must be accurately conditioned before sampling. Its 112 dB typical CMRR makes it effective at rejecting 50 Hz or 60 Hz power-line interference in analog front ends connected to industrial sensors. Low-power portable test instruments and battery-operated signal analyzers also benefit from its low-power operation while maintaining the 35 MHz bandwidth needed for wideband signal chains.

Frequently Asked Questions
What bandwidth and CMRR does the LTC6363IMS8-2 provide, and how do they benefit ADC driving applications?
The LTC6363IMS8-2 offers a 35 MHz 3dB bandwidth and a 112 dB typical common-mode rejection ratio (CMRR), with a guaranteed minimum of 85 dB. The 35 MHz bandwidth allows it to drive 16-bit or 18-bit SAR ADCs with Nyquist rates above 1 MSPS without gain rolloff in the signal passband. The 112 dB CMRR ensures that common-mode noise on differential signal lines — such as 50 Hz or 60 Hz power-line interference — is attenuated by a factor of over 400,000, preserving LSB-level accuracy in precision measurement systems.
How does the 0.1 µA maximum bias current of the LTC6363IMS8-2 affect high-impedance sensor interface designs?
An input bias current maximum of 0.1 µA limits the voltage error at the differential amplifier input to less than 0.1 µA × source impedance. For a 10 kΩ source impedance, the resulting offset error is no more than 1 mV, which is within the acceptable error budget for most 16-bit measurement systems. This low bias current makes the LTC6363IMS8-2 suitable for driving ADCs from high-impedance bridge sensors, electrochemical electrodes, or precision resistive dividers without buffering stages that would increase power consumption and noise.
For a 16-bit ADC driver design, when is the LTC6363IMS8-2 preferable to a discrete op-amp gain stage?
The LTC6363IMS8-2 integrates matched internal resistors that set a precise gain of 2 V/V (the -2 suffix), eliminating the resistor matching tolerance error that limits CMRR in discrete differential amplifier circuits. External discrete resistors matched to 0.1% still yield only 66 dB CMRR, versus the LTC6363IMS8-2's guaranteed 85 dB minimum. This makes the integrated approach preferred whenever the common-mode rejection budget requires more than 70 dB, such as in 16-bit systems where a single LSB corresponds to less than 50 µV of differential signal.
What operating temperature range and package does the LTC6363IMS8-2 support, and how does this affect procurement for industrial designs?
The LTC6363IMS8-2 is the industrial-temperature-grade variant, supporting operation from -40°C to +85°C, as indicated by the I-grade designation. It is housed in an MSOP-8 package (8-pin Mini Small Outline Package) with a 0.65 mm lead pitch, suitable for standard SMT reflow assembly. The #TRPBF suffix confirms it ships in tape-and-reel format with RoHS-compliant lead-free terminations, making it compatible with modern lead-free manufacturing lines and CE/UKCA-marked end products.
