What are the key features of LT1638IMS8#TRPBF?
- Rail-to-rail input and output enabling full-swing signal processing on ±22 V or 44 V single supply
- 80 dB minimum CMRR with 88 dB typical for precise signal rejection in noisy automotive environments
- Dual-amplifier configuration in an 8-pin MSOP package reducing board space while providing two independent signal channels
- AEC-Q100 automotive grade with 1500 µV maximum input offset voltage for temperature-stable precision measurement
What is LT1638IMS8#TRPBF used for?
The LT1638IMS8#TRPBF is designed for automotive signal conditioning, including sensor interface circuits and filter stages in body electronics and powertrain control modules operating from a wide 44 V bus. Its dual rail-to-rail channels also serve industrial data-acquisition front ends and portable instrumentation where low bias current (0.05 µA max) and high CMRR are needed across extended temperature ranges.

Frequently Asked Questions
What supply voltage range does the LT1638IMS8#TRPBF support and how does it handle rail-to-rail signals?
The LT1638IMS8#TRPBF operates on a split supply up to ±22 V or a single supply up to 44 V, and its rail-to-rail input and output allow the signal to swing within millivolts of both supply rails. This enables maximum dynamic range in high-voltage automotive sensor circuits without headroom loss.
How does the LT1638IMS8#TRPBF CMRR performance benefit automotive sensor designs?
With a minimum CMRR of 80 dB and a typical value of 88 dB, the LT1638IMS8#TRPBF effectively rejects common-mode noise from the 12 V or 24 V automotive bus. This is critical for accurate pressure, temperature, and position sensor readings in noisy powertrain control unit environments.
When is the LT1638IMS8#TRPBF a better fit than a single op-amp for a compact filter design?
Because the LT1638IMS8#TRPBF integrates 2 independent amplifiers in an 8-pin MSOP package, it replaces two single op-amp ICs, halving the component count and cutting PCB footprint by roughly 50% compared to a dual-SO-8 solution. This is advantageous in multi-pole active filter implementations with tight board area constraints.
What is the maximum bias current of the LT1638IMS8#TRPBF and why does it matter for high-impedance sensor inputs?
The LT1638IMS8#TRPBF specifies a maximum average bias current of 0.05 µA, which causes less than 50 nV of error across a 1 kΩ source impedance. This low bias current makes it suitable for interfacing with high-impedance sensors such as electrochemical cells or photodiodes in measurement systems requiring sub-millivolt accuracy.
