Product details

Overview

LM358ADT from STMicroelectronics is a low-power dual operational amplifier in SO8 package, 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.), 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 LM358ADT datasheet, LM358ADT pinout, LM358ADT application, or LM358ADT equivalent, this page delivers verified technical context, real-world design meaning of key specs, validated pin functions, application-specific use cases, and confirmed alternative parts with documented functional differences.

Technical Context

The LM358ADT integrates two independent, internally frequency-compensated op amps optimized for single-supply operation. Its input stage uses PNP transistors enabling common-mode input voltage range extending to the negative rail (0 V), while the output stage supports 0 V to (V_CC − 1.5 V) swing under load.

It delivers stable performance across 0 °C to 70 °C ambient temperature, with 20 nA max input bias current, 2 nA max input offset current, and 65–100 dB supply voltage rejection ratio - making it suitable for DC-coupled amplification and precision summing where supply ripple immunity matters.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 30 V - enables direct interface with 5 V logic systems and 24 V industrial rails without level-shifting.
Large-Signal Voltage Gain	100 dB (typ.) - provides ≥10 V/mV open-loop gain for high-accuracy closed-loop gain setting at low frequencies.
Unity-Gain Bandwidth	1.1 MHz (typ.) - supports audio-band amplification and moderate-speed sensor signal conditioning up to ~100 kHz.
Input Offset Voltage	2 mV (max) - ensures ≤2 mV DC error in precision DC amplifiers without external trimming.
Input Bias Current	20 nA (max) - allows use with high-impedance sources (e.g., thermistors, photodiodes) without significant voltage drop.
Output Voltage Swing	0 V to (V_CC − 1.5 V) - enables true ground-referenced output in single-supply configurations, critical for ADC driver stages.
Supply Current per Channel	0.7 mA (typ. at 5 V) - supports battery-powered or energy-constrained applications with dual-channel analog signal processing.

Pinout & Package

LM358ADT is housed in an SO8 (Small Outline 8-pin) package with standard 1.27 mm pitch, compliant with ECOPACK® environmental specifications. The package features gull-wing leads, surface-mount compatibility, and thermal resistance of 125 °C/W (junction-to-ambient).

Pin/Terminal	Circuit Role	Design Meaning
1	Output A	Amplifier A output node; capable of sourcing/sinking ≥20 mA and swinging to 0 V in single-supply mode.
2	Inverting Input A	High-impedance input (20 nA bias) for feedback network connection in inverting configurations.
3	Non-inverting Input A	DC-coupled input accepting signals down to ground; common-mode range includes V_CC− (0 V).
4	V_CC− / GND	Ground reference for both amplifiers; must be low-impedance to minimize noise coupling between channels.
5	Non-inverting Input B	Independent input for second amplifier; identical electrical characteristics to Pin 3.
6	Inverting Input B	Second amplifier's inverting node; supports separate feedback paths without crosstalk.
7	Output B	Second amplifier output; electrically isolated from Output A but shares same supply pins.
8	V_CC+	Positive supply rail; supplies both amplifiers; decoupling capacitor required within 1 cm for stability.

Key Features

Feature	Design Value
Internal Frequency Compensation	Enables stable unity-gain operation without external compensation components, reducing BOM count and layout complexity.
Rail-to-Rail Input Common-Mode Range	Accepts inputs from 0 V to (V_CC − 1.5 V), allowing direct interfacing with ground-referenced sensors and DAC outputs.
Low Input Bias Current (20 nA)	Minimizes loading error on high-impedance sources like pH electrodes or piezoelectric transducers.
Single-Supply Operation (3–30 V)	Eliminates need for split supplies in embedded systems, simplifying power architecture and PCB routing.
Channel Separation >120 dB	Prevents signal coupling between amplifiers in dual-channel applications such as differential instrumentation or stereo audio preamps.

Use Value: 0.02% THD at 1 kHz and 55 nV/√Hz input noise preserve dynamic range and low-noise performance.

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
LM358DT	Same SO8 package and pinout; wider input offset voltage (2–7 mV vs. 1–3 mV for LM358A); no A-grade screening.	Lower accuracy requirement; cost-sensitive consumer applications where ±5 mV offset is acceptable.	Select LM358DT when absolute DC precision is not critical and budget constraints dominate.
LM2904DT	Automotive-qualified (−40 °C to 105 °C); identical electrical specs except enhanced ESD rating (2 kV HBM vs. 300 V).	Under-hood automotive sensors, ADAS power management, and industrial equipment requiring extended temperature reliability.	Choose LM2904DT for AEC-Q100 compliance and higher robustness in harsh environments.

Compared with LM358DT, LM358ADT offers tighter input offset voltage tolerance and improved temperature stability; versus LM2904DT, it trades automotive qualification for lower cost and standard industrial temperature grade - guiding selection based on accuracy priority versus environmental ruggedness.

FAQ

Is LM358ADT pin-compatible with LM358DT?

Yes, LM358ADT and LM358DT share identical SO8 pinout, footprint, and electrical connections. Both use Pins 1/7 for outputs, Pins 2/6 for inverting inputs, Pins 3/5 for non-inverting inputs, and Pins 4/8 for ground and V_CC+. No PCB redesign is needed when upgrading from DT to ADT for improved DC accuracy.

What is the maximum capacitive load LM358ADT can drive stably?

LM358ADT maintains phase margin >30° with up to 290 pF capacitive load at V_CC = 15 V and I_OUT = 0 µA, per Figure 18 in the datasheet. For loads >100 pF, add a 10–100 Ω series resistor between output and capacitor to isolate reactive feedback and prevent oscillation in driving ADC input capacitors or long cables.

Does LM358ADT support rail-to-rail output?

LM358ADT supports rail-to-rail *input* common-mode range (down to 0 V), but its output swings from 0 V to (V_CC − 1.5 V) - not full rail-to-rail. At V_CC = 5 V, minimum output is 0 V and maximum is ~3.5 V; at V_CC = 30 V, maximum is ~28.5 V. This 1.5 V headroom limits use in applications requiring true V_CC output saturation.

Can LM358ADT operate from a 3.3 V supply?

Yes, LM358ADT is fully specified down to 3 V supply voltage. At 3.3 V, it delivers usable output swing (0 V to ~1.8 V), 100 dB gain, and 20 nA input bias current. However, slew rate drops to ~0.2 V/µs and GBP reduces to ~0.7 MHz - sufficient for DC and low-frequency (<10 kHz) applications like sensor buffering but not high-speed signal chains.
