Summary of the LM358EDR2G by onsemi

The LM358EDR2G from onsemi is a widely utilized dual general-purpose operational amplifier, implemented in an 8-pin SOIC package. As part of the LM358 series, the device is designed for single-supply operation ranging from 3.0 V to 32 V and also supports split supply configurations. The LM358EDR2G integrates two independent operational amplifiers, offering engineers flexibility for various analog signal processing tasks within compact designs.

The LM358EDR2G has a heritage rooted in the robust LM324 quad op-amp architecture, essentially providing half the circuitry in a dual configuration for applications where two channels suffice. The common mode input voltage range includes the negative supply (ground), enabling operation without complex biasing circuitry and easing integration into single-supply systems. The device’s output can swing to the negative rail, further simplifying design.

Main Design Attributes of LM358EDR2G

The LM358EDR2G is built around two internally compensated, two-stage amplifiers. Its input stage leverages a true differential topology, enabling accurate signal processing for both inverting and non-inverting applications. Input buffer transistors maintain high integrity of the input signals, while the differential-to-single-ended converter ensures efficient level shifting.

A notable design advantage is transconductance reduction accomplished through splitting the input device collectors. This lowers the value of the required compensation capacitor (down to 5 pF), reducing silicon area and improving fabrication efficiency. Additionally, internally regulated biasing imparts excellent temperature stability and power supply rejection, both critical for robust operation in real-world engineering environments.

Other architectural features include:

Short-circuit protected outputs, safeguarding the device against accidental load faults

Low input bias currents, reducing errors from source impedance

ESD protection clamps on inputs, enhancing device ruggedness without impacting analog performance

Internal compensation, eliminating the need for external stabilization components

LM358EDR2G Electrical Specifications and Performance

At the core of device selection for analog front-ends is the precise understanding of electrical behavior. The LM358EDR2G supports operation from 3 V up to 32 V supply voltage, allowing seamless deployment in battery-powered, industrial, and automotive systems. Typical applications run with VCC = 5 V, and the device’s quiescent current is approximately one-fifth that of classic amplifiers like the MC1741.

Temperature ranges differ by model:

LM358EDR2G: 0°C to +70°C

Variation in associated series devices permits operation across –40°C up to +125°C (refer to LM2904V/NCV2904)

Input common mode voltage is allowed to swing from –0.3 V relative to the negative rail, up to VCC –1.7 V. For robust circuit protection, input signals can go up to +32 V without device damage even if VCC is lower.

The outputs can be shorted to ground or to the positive rail, but caution is needed with simultaneous multiple output shorts to avoid destructive device heating. The large signal performance exhibits quick response suitable for voltage follower configurations, and the open loop gain provides wide bandwidth for most general-purpose applications.

Its input and output range flexibility simplify single-supply analog processing—essential for modern battery-driven or embedded systems.

Design Guidelines for Integrating LM358EDR2G

Selecting the LM358EDR2G for a project requires awareness of several engineering factors:

Input signal ranges: Ensure that neither input voltage falls below –0.3 V relative to the negative rail, and stays within VCC –1.7 V at the maximum.

Output protection: While short circuit protection exists, avoid simultaneous output shorts for all contained amplifiers.

Power dissipation: Evaluate total consumption during load faults—especially relevant for quadruple or dual configurations in parallel.

Temperature rating: Confirm that the operating temperature range of the chosen sub-series matches the environmental conditions for your design.

Bias currents: Minimize error by considering input bias current contributions for high-impedance source scenarios.

Application circuit topology: Leverage the device’s single and split supply support to optimize power supply requirements and analog performance.
