What are the key features of LT1638IMS8#PBF?
- Rail-to-rail input and output swing on a single supply from 2.7V to 36V or dual supply up to ±18V for maximum dynamic range in precision signal conditioning
- Ultra-low 0.05 µA maximum bias current enables accurate signal processing with high-impedance sensors such as photodiodes and pH electrodes
- 88 dB typical CMRR (80 dB minimum) ensures excellent common-mode noise rejection in differential sensing and instrumentation amplifier circuits
- Dual amplifier in compact 8-pin MSOP package saves board space in portable instrumentation and battery-powered measurement devices
What is LT1638IMS8#PBF used for?
The LT1638IMS8#PBF is commonly used in battery-powered instrumentation and sensor signal conditioning where its rail-to-rail output swing maximizes dynamic range on 3.3V or 5V single supplies. Its ultra-low 0.05µA bias current makes it ideal for high-impedance transducer interfaces such as photodiode amplifiers, pH meter front-ends, and strain gauge bridges. The dual op-amp configuration in an 8-pin MSOP package is also popular in precision filter designs, active rectifiers, and low-power audio preamplifiers.

Frequently Asked Questions
What makes LT1638IMS8#PBF suitable for high-impedance sensor interfaces?
LT1638IMS8#PBF has a maximum average bias current of only 0.05 µA, which causes negligible voltage error across high source impedances such as photodiodes, pH electrodes, or thin-film strain gauges. At a 10 MΩ source impedance, the bias current introduces only 0.5 mV of input error, making it one of the lower-bias-current choices in its class for precision sensor interfacing.
What supply voltage range does LT1638IMS8#PBF support and can it operate on a single 3.3V rail?
LT1638IMS8#PBF operates from a single supply of 2.7V to 36V or dual supplies up to ±18V, making it fully compatible with 3.3V, 5V, and 12V systems. Its rail-to-rail input common-mode range and rail-to-rail output swing are maintained across this entire voltage range, enabling maximum signal utilization in low-voltage IoT and portable medical devices.
How does LT1638IMS8#PBF compare to a standard op-amp for single-supply 5V filter designs?
Unlike standard bipolar op-amps that require split supplies and cannot swing within millivolts of the supply rails, LT1638IMS8#PBF provides true rail-to-rail output within a few millivolts of both rails on a single 5V supply. Its 1 MHz gain-bandwidth product supports active filter designs up to several hundred kHz, and its 88 dB CMRR suppresses power supply ripple in sensitive audio and instrumentation filter stages.
What is the CMRR specification of LT1638IMS8#PBF and when does it matter in circuit design?
LT1638IMS8#PBF specifies 88 dB typical CMRR and 80 dB minimum CMRR, representing the amplifier's ability to reject signals common to both inputs such as 50/60 Hz hum or power supply noise. High CMRR is critical in differential temperature sensing, current shunt monitoring, and bridge amplifier circuits where common-mode voltages from long cable runs or noisy ground planes would otherwise degrade measurement accuracy.
