Key Features
- Dual rail-to-rail input and output (R-R I/O) op-amp enabling full supply range signal swing from ±15V or 30V single supply
- 2.2 µA maximum bias current at 25°C and 3000 µV maximum input offset voltage for precision measurement applications
- 81 dB minimum common-mode rejection ratio (CMRR) ensuring accurate differential signal amplification
- 8-pin SOIC package with voltage-feedback architecture compatible with standard op-amp circuit topologies
Applications
The LT1632IS8 is well-suited for precision signal conditioning in data acquisition systems, strain gauge amplifiers, and industrial sensor interfaces where full rail-to-rail output swing is required from ±15V supplies. Its high CMRR of 81 dB minimum makes it effective in bridge amplifier circuits and instrumentation front-ends operating in electrically noisy industrial environments. The dual-channel package allows differential to single-ended conversion with two stages in one 8-pin SOIC, reducing board space in multi-channel precision measurement designs.

Frequently Asked Questions
For a strain gauge bridge amplifier operating on ±15V supplies, how does LT1632IS8 handle near-rail input voltages?
The LT1632IS8 features rail-to-rail input operation, allowing common-mode input voltages to extend from the negative supply to the positive supply rail. On ±15V supplies this means inputs can swing from -15V to +15V, ensuring the op-amp accurately amplifies differential bridge signals even when common-mode voltages approach the supply rails, which is critical in bridge amplifier applications.
What is the maximum input offset voltage and bias current of LT1632IS8, and how do these affect DC accuracy?
The LT1632IS8 specifies a maximum input offset voltage of 3000 µV (3 mV) and a maximum input bias current of 2.2 µA at 25°C. For high-impedance signal sources, the bias current through source resistance creates a voltage error; at 2.2 µA through a 10 kohm source, this adds 22 mV of offset, so low-impedance sources or offset trimming should be considered for sub-millivolt accuracy requirements.
Can LT1632IS8 operate from a single-ended 12V supply in an embedded sensor interface design?
The LT1632IS8 is rated for supplies from ±15V down to lower supply voltages, but its specified operating range is ±15V/30V total supply. For a 12V single supply, the total voltage is within the absolute maximum of 30V, and the rail-to-rail I/O ensures output can swing close to both ground and 12V, enabling single-supply sensor signal conditioning without a bipolar supply rail.
When would an engineer choose LT1632IS8 over a single op-amp in a data acquisition front-end?
The LT1632IS8 integrates 2 op-amp channels in a single 8-pin SOIC package, enabling differential to single-ended conversion, filtering, and gain stages in half the board footprint of two separate single op-amp packages. With 81 dB minimum CMRR and rail-to-rail I/O on ±15V supplies, it is particularly efficient in multi-channel ADC input conditioning designs where board density and matched channel performance are both important.
