Key Features
- Dual op-amp channels in a single 8-pin SOIC saving board space versus two single-channel devices
- 70 dB minimum CMRR (80 dB typical) for effective rejection of common-mode noise in signal conditioning circuits
- Ultra-low 0.3 µA maximum input bias current reducing error in high-source-impedance sensor interfaces
- Wide supply voltage range supporting single-supply and dual-supply designs across industrial voltage rails
- Internally frequency-compensated for unity-gain stability, simplifying closed-loop filter and amplifier design
Applications
The LM258DE4 is used in industrial sensor signal conditioning circuits where a low-bias-current, voltage-feedback amplifier is needed to amplify millivolt-level outputs from bridge sensors, thermocouples, and piezoelectric transducers. Battery-powered data acquisition front-ends benefit from its low quiescent current and wide supply range, allowing operation from a single 5 V or 3.3 V rail. Audio and consumer electronics designers use it in active filter stages and comparator applications where an 8-pin SOIC dual amplifier reduces component count and PCB area.

Frequently Asked Questions
What is the input bias current specification of the LM258DE4, and how does it affect high-impedance sensor circuits?
The LM258DE4 has a maximum input bias current of 0.3 µA at 25°C, producing a worst-case voltage error of only 30 mV across a 100 kΩ source impedance, making it suitable for bridge sensor and photodiode amplifier designs without additional bias compensation resistors.
How does the LM258DE4 achieve 70 dB CMRR, and why is this important for industrial differential signal measurement?
The LM258DE4 achieves a minimum 70 dB common-mode rejection ratio (80 dB typical), meaning a 1 V common-mode signal appearing on both inputs is attenuated to below 0.3 mV at the output, enabling accurate differential measurement in electrically noisy industrial environments with ±50 V common-mode transients.
For a 4–20 mA loop sensor interface, what supply voltage range does the LM258DE4 support?
The LM258DE4 operates from a single supply of 3 V to 32 V or a dual supply of ±1.5 V to ±16 V, covering the 5 V and 12 V rails common in 4–20 mA loop-powered transmitter designs without requiring a separate voltage regulator for the op-amp.
What package does the LM258DE4 use, and how does the DE4 suffix affect procurement?
The LM258DE4 is housed in an 8-pin SOIC (R-PDSO-G8) with a 1.27 mm pitch, a widely available footprint supported by automated assembly. The DE4 suffix denotes a tape-and-reel package of 2500 units, lowering per-unit cost in production volumes above 500 pieces compared to tube-packaged variants.
When would a designer choose the LM258DE4 over a rail-to-rail output op-amp for a 5 V single-supply comparator application?
The LM258DE4 is preferred when load resistors are used to pull the output toward the positive rail because its open-collector-style output stage can sink 20 mA at low saturation voltage, whereas rail-to-rail output op-amps in comparator mode may exhibit slower transition times or higher propagation delay above 1 µs when driving logic levels.
