Texas Instruments LM358DR

LM358DR Overview

The LM358DR device is a dual-channel operational amplifier (op amp) from Texas Instruments, housed in an SOIC-8 package. It includes two independent high-gain amplifiers with internal frequency compensation, making it suitable for a wide range of analog signal processing applications.
This device is ideal for both single-supply and dual-supply operations. The wide supply voltage range, low power consumption, and robust EMI performance make LM358DR a popular choice in consumer, industrial, and automotive electronics.
LM358 devices can operate from a split supply voltage as long as the difference between the two supplies is within 3 V to 32 V. Their low quiescent current, high input impedance, and low offset voltage make them an excellent choice for signal conditioning circuits such as voltage followers, sensor amplifiers, and more.

LM358DR Features

✅ Wide Supply Voltage Range: 3V to 36V (single) or ±1.5V to ±18V (dual)
✅ Low Power Consumption: Typical quiescent current is only 300 μA per amplifier
✅ Unity-Gain Bandwidth: 1.2 MHz typical
✅ Low Input Offset Voltage: Max 3 mV (2 mV for BA version)
✅ Common-Mode Input Range Includes Ground
✅ Integrated EMI and RF Filters (B and BA versions)
✅ Internal Frequency Compensation: Stable without external components
✅ MIL-PRF-38535 compliant versions available for military/space-grade reliability

LM358DR FAQ

Q1: Can LM358DR operate with a single power supply?

A: Yes. The LM358 is specifically designed for single-supply systems, supporting voltages as low as 3V and as high as 36V.

Q2: Is LM358DR suitable for low-power applications?

A: Absolutely. With a typical quiescent current of only 300 μA per channel, it is ideal for battery-powered or energy-conscious designs.

Q3: Does it support input signals near ground?

A: Yes. The input common-mode voltage range includes ground, which is useful for low-side current sensing and signal acquisition.

Q4: How does LM358DR compare to LM324?

A: LM324 is a quad op-amp (4 channels), while LM358 contains only two. Electrical characteristics are similar, and they are often interchangeable based on channel requirements.

Q5: Can LM358DR be used as a comparator?

A: Technically yes, but for faster response and rail-to-rail outputs, a dedicated comparator like the LM393 is recommended.

Q6: What is the typical use in signal acquisition?

A: LM358DR is often used as a voltage follower (buffer) to prevent loading of the signal source and to raise input impedance.
