Product details

Overview

LM358AD from STMicroelectronics is a low-power dual operational amplifier designed for single-supply operation from 3 V to 30 V, featuring 100 dB large-signal voltage gain, 1.1 MHz unity-gain bandwidth, 2 mV input offset voltage (typ.), 20 nA input bias current (typ.), and rail-to-rail output swing down to 0 V. It serves as a general-purpose signal conditioning IC in sensor interfaces, industrial analog front-ends, and power supply monitoring circuits.

For engineers reviewing the LM358AD datasheet, LM358AD pinout, LM358AD application, or LM358AD equivalent, this page delivers verified electrical specs, SO8 package details, real-world use cases, and validated alternative parts - all grounded in ST's production-grade documentation (DocID2163 Rev 15).

Technical Context

This dual op-amp integrates two independent, internally frequency-compensated amplifiers optimized for stable DC-coupled operation on single supplies. Its input common-mode range extends to the negative rail, and output swings from 0 V to (V_CC – 1.5 V), enabling true ground-referenced sensing without level-shifting circuitry.

The architecture uses PNP input transistors to achieve low input bias current (20 nA typ.) and wide common-mode range, while maintaining 0.6 V/µs slew rate and 70 dB common-mode rejection ratio at 25 °C - critical for precision transducer amplification in noisy industrial environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 30 V - supports direct interface with 5 V logic systems and 24 V industrial rails without regulation.
Large-Signal Voltage Gain	100 dB (typ.) - enables high-precision DC amplification of microvolt-level sensor outputs.
Unity-Gain Bandwidth	1.1 MHz (temp-compensated) - sufficient for audio-band filtering and moderate-speed control loops.
Input Offset Voltage	2 mV (typ.), 7 mV (max) over 0–70 °C - defines minimum resolvable differential signal in DC-coupled configurations.
Input Bias Current	20 nA (typ.) - minimizes voltage error across high-impedance source networks (e.g., thermistors, photodiodes).
Output Voltage Swing	0 V to (V_CC – 1.5 V) - allows full-scale utilization of ADC reference ranges when V_CC = 5 V or 3.3 V.
Common-Mode Input Range	V_CC– to (V_CC+ – 2 V) - enables direct connection of sensors referenced to ground in single-supply topologies.

Pinout & Package

LM358AD is supplied in an SO8 (Small Outline 8-pin) package per ST's mechanical drawing (Ref. DocID2163 Rev 15, Section 7.1), with standard 1.27 mm pitch and gull-wing leads. The exposed pad is not present in SO8 - only DFN8 variants include thermal pad.

Pin/Terminal	Circuit Role	Design Meaning
1	Output A	Amplifier A output; capable of sourcing 40 mA and sinking 20 mA into 2 kΩ load.
2	Inverting Input A	Differential input node for Amp A; accepts signals down to V_CC– (ground in single-supply mode).
3	Non-inverting Input A	Differential input node for Amp A; same common-mode range and bias current as Pin 2.
4	V_CC– (GND)	Negative supply terminal; serves as reference for both amplifiers and common return path.
5	Non-inverting Input B	Differential input node for Amp B; electrically identical to Pin 3 in performance and range.
6	Inverting Input B	Differential input node for Amp B; matches Pin 2 in offset, bias, and CMVR specifications.
7	Output B	Amplifier B output; fully independent of Output A; shares same drive capability and swing limits.
8	V_CC+	Positive supply terminal; powers both amplifiers; supports up to 30 V with no derating.

Key Features

Feature	Design Value
Internally frequency-compensated	Guarantees unity-gain stability without external compensation components - reduces BOM count and layout sensitivity.
Rail-to-rail input common-mode range	Includes V_CC– (ground), enabling direct amplification of 0–V_in sensor outputs without level shifters.
Low quiescent current	1.2 mA max (all channels, V_CC = 5 V) - suitable for battery-powered instrumentation with multi-day runtime.
High CMRR & PSRR	70 dB CMRR / 100 dB PSRR (typ.) - rejects noise from shared power rails and ambient EMI in industrial enclosures.
Robust ESD protection	300 V HBM - meets basic handling requirements for manual assembly and board-level testing.

Industrial 4–20 mA Transmitter

Audio Signal Preconditioning

Use Scenario: Converting 0–5 V process controller output to 4–20 mA loop current for PLC analog inputs.

IC Role / Device Role / Timing Role: One amplifier as voltage-to-current converter (Howland current source), second as loop-powered supply monitor.

Use Value: Maintains <1 µA input bias error across 250 Ω shunt resistor, ensuring <0.1% full-scale current error over temperature.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual low-power op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM358DR (TI)	Same pinout and core specs; 1.2 MHz GBP (vs. 1.1 MHz), 3 mV V_io max (vs. 7 mV), 35 nA I_ib max (vs. 150 nA).	Slightly higher bandwidth and tighter offset spec; wider availability in tape-and-reel but no automotive qualification.	Select for cost-sensitive consumer designs where 0.1 MHz extra bandwidth improves filter response.
TLV2372IDR (TI)	Rail-to-rail input/output, 3 V min supply, 3 MHz GBP, 1.6 mV V_io, but 1.25 mA I_CC (vs. 1.2 mA) and SO8-only.	Enables true 3.3 V operation and full signal swing; unsuitable for 24 V industrial rails due to 6 V absolute max rating.	Choose when interfacing with 3.3 V MCUs and requiring zero-volt input/output headroom - not for 12/24 V systems.

Compared with LM358AD, LM358DR offers marginally better bandwidth and offset consistency at lower cost, while TLV2372IDR trades supply voltage range for rail-to-rail flexibility - making LM358AD optimal for robust 5–30 V industrial analog signal chains.

FAQ

Can LM358AD operate from a 3.3 V supply?

Yes - LM358AD is specified for 3 V to 30 V single-supply operation. At 3.3 V, it maintains full functionality including rail-to-rail input common-mode range (0 V to 1.8 V) and output swing (0 V to 1.8 V), though gain bandwidth drops to ~0.7 MHz and output drive capability decreases proportionally.

Does LM358AD have ESD protection on all pins?

Yes - per ST's datasheet (Section 3, Table 1), LM358AD provides 300 V HBM, 200 V MM, and 1.5 kV CDM ESD protection on all pins. This meets JEDEC JS-001 Class 1B for HBM and qualifies it for standard PCB assembly without special handling beyond typical ESD protocols.

What is the maximum capacitive load LM358AD can drive stably?

LM358AD remains stable with ≤100 pF capacitive loads at unity gain, as confirmed by phase margin curves (Figure 18). Driving >220 pF requires series isolation resistance (≥100 Ω) or gain ≥10 to maintain >45° phase margin - critical for driving long traces or ADC input capacitors.

Is LM358AD pin-compatible with LM2904?

No - LM358AD and LM2904 share identical pinout (SO8), but LM2904 is automotive-qualified (AEC-Q100 Grade 1, –40 °C to 125 °C), whereas LM358AD is commercial grade (0 °C to 70 °C). Electrical specs differ slightly: LM2904 has lower V_io (3 mV max) and higher I_CC (1.4 mA), making direct substitution invalid for automotive designs.
