Applications
The LT1013CDRE4 is well-suited for precision instrumentation amplifiers, thermocouple signal conditioning, and bridge sensor interfaces that demand low offset and high CMRR in industrial and medical measurement systems. Its dual channel configuration allows designers to implement differential amplification and active filtering in a single 8-pin SOIC package, saving board area. Data acquisition front-ends and battery-powered sensors also benefit from the device's stable DC performance across temperature.

Frequently Asked Questions
How low is the input offset voltage of the LT1013CDRE4, and why does this matter for precision sensor circuits?
The LT1013CDRE4 guarantees a maximum input offset voltage of 400 µV, which translates to less than 0.4 mV of DC error at the amplifier output before gain. For a sensor bridge amplified at gain 100, this limits worst-case zero-point error to just 40 mV, enabling accurate measurements without manual offset trimming.
What common-mode rejection ratio does the LT1013CDRE4 achieve, and how does this benefit industrial noise environments?
The device achieves a minimum CMRR of 97 dB and a typical CMRR of 114 dB. In industrial settings with 50 Hz or 60 Hz mains interference on signal lines, a 97 dB CMRR attenuates common-mode noise by over 70,000:1, preserving small differential signals in the microvolt range.
Can the LT1013CDRE4 operate from a single supply, and what voltage range is supported?
Yes, the LT1013CDRE4 supports dual supply operation up to ±15 V (30 V total) and can also run from a single 30 V rail when biasing is arranged correctly. This flexibility makes it suitable for both legacy ±15 V instrumentation systems and modern single-supply 3.3 V to 5 V battery-powered designs.
For a thermocouple amplifier design, how does the LT1013CDRE4's bias current of 38 nA max affect accuracy?
With a maximum bias current of 38 nA and an input offset current of only 2 nA max, voltage error across a 10 kΩ source impedance stays below 0.38 mV, contributing less than 0.4 µV referred-to-input at unity gain, well within the tolerance budget for most thermocouple measurement systems.
