Key Features
- Dual voltage-feedback op-amp operating on ±15 V / 30 V single supply rails
- 94 dB minimum CMRR with 114 dB typical for high-precision differential signal rejection
- Low input bias current max of 50 nA at 25°C enabling high-impedance source buffering
- Internal frequency compensation for unity-gain stability in 8-pin PDIP package
Applications
The LT1013DPE4 is commonly used in precision instrumentation front-ends, strain gauge bridges, and thermocouple signal conditioners where low offset and high CMRR are critical. Its dual op-amp topology allows differential-to-single-ended conversion and active filtering within a single 8-pin package. Industrial data acquisition systems and medical measurement equipment benefit from its stable performance over the full supply voltage range.

Frequently Asked Questions
What is the CMRR specification of LT1013DPE4 and why does it matter for differential signal applications?
The LT1013DPE4 achieves a minimum CMRR of 94 dB and a typical 114 dB, meaning common-mode noise signals are rejected by over 5 million to 1. This level of rejection is essential in 4-20 mA industrial current loops and strain gauge bridges where ground noise easily exceeds the signal of interest.
How does the LT1013DPE4 input bias current specification affect circuit design with high-impedance sources?
With a maximum input bias current of 50 nA at 25°C and 38 nA average, LT1013DPE4 introduces minimal error when used with source impedances up to several megaohms. Designers can use feedback resistors above 100 kΩ without significant gain error, a key advantage for pH sensors and photodiode transimpedance amplifiers.
Can LT1013DPE4 operate from a single 30 V supply instead of split ±15 V rails?
Yes, LT1013DPE4 is rated for a total supply voltage of 30 V, which can be applied as ±15 V dual supply or as a single 30 V rail. This flexibility lets designers power the device from common industrial 24 V or 28 V bus voltages using a simple resistor divider mid-rail reference for the input common-mode range.
How does the 8-pin PDIP package of LT1013DPE4 affect prototype and production board assembly?
The PDIP-8 package with 2.54 mm pin pitch allows direct hand soldering and breadboard prototyping without adapters, reducing development iteration time. For production, it fits standard DIP-8 sockets, enabling easy field replacement in industrial control systems that require in-field servicing of analog conditioning circuits.
