Product details

Overview

LM358YDT from STMicroelectronics is an automotive-grade, low-power dual operational amplifier in SO8 package, featuring 100 dB DC gain, 1.1 MHz unity-gain bandwidth, 2 mV input offset voltage, 20 nA input bias current, and rail-to-rail output swing (0 V to V_CC − 1.5 V) - designed for single-supply sensor signal conditioning in engine control units and body electronics.

For engineers reviewing the LM358YDT datasheet, LM358YDT pinout, LM358YDT application, or LM358YDT equivalent, this part supports transducer amplification, DC gain blocks, and comparator functions in 5 V–30 V automotive systems where input common-mode range includes ground and thermal stability across −40 °C to +105 °C is required.

Technical Context

The LM358YDT integrates two independent, internally frequency-compensated op amps optimized for single-supply operation. Its PNP-input stage enables input common-mode voltage down to the negative rail (ground), while its NPN output stage delivers 40 mA source/sink capability with output swing within 1.5 V of V_CC.

It exhibits temperature-compensated parameters: ±2 mV max input offset voltage at 25 °C, 7–30 µV/°C drift, and supply current of 0.7–1.2 mA per amplifier at 5 V - stable across full automotive temperature range (−40 °C to +105 °C) and compliant with AEC-Q100 Grade 2.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	3 V to 30 V - supports direct interface with 5 V logic and 12 V/24 V automotive rails without level-shifting.
Input Offset Voltage	2 mV (max at 25 °C) - ensures ≤20 mV error in 10× gain sensor amplifiers at room temperature.
Unity-Gain Bandwidth	1.1 MHz - sufficient for <100 kHz analog signal paths including throttle position and coolant temperature conditioning.
Large-Signal Voltage Gain	100 dB - provides ≥100,000× open-loop gain for precision DC amplification with <0.1% linearity error.
Output Current Drive	±40 mA - directly drives LEDs, small relays, or ADC reference buffers without external boost stages.
Common-Mode Input Range	Ground to (V_CC − 2 V) - enables direct connection of grounded thermistors or bridge sensors without biasing networks.
Quiescent Current per Channel	0.7–1.2 mA at 5 V - enables low-power always-on monitoring circuits in battery-sensitive modules.

Pinout & Package

LM358YDT is housed in an SO8 (Small Outline 8-pin) package per JEDEC MS-012, with standard 1.27 mm pitch, 5.0 mm × 4.0 mm body, and gull-wing leads. Thermal resistance R_thJA = 125 °C/W enables operation up to +105 °C ambient without forced cooling.

Pin/Terminal	Circuit Role	Design Meaning
1	Output A	Amplifier A output node - capable of sourcing/sinking ±40 mA with 0 V to (V_CC − 1.5 V) swing.
2	Inverting Input A	High-impedance (20 nA bias) differential input - accepts feedback networks for inverting configurations.
3	Non-inverting Input A	High-impedance input tied to sensor or reference - supports DC-coupled transducer interfaces.
4	V_CC− / GND	Negative supply terminal - referenced to system ground in single-supply use; must be low-impedance.
5	Non-inverting Input B	Independent second amplifier input - enables dual-channel functions like differential-to-single-ended conversion.
6	Inverting Input B	Second amplifier inverting node - used for active filtering or summing with channel A.
7	Output B	Amplifier B output - electrically isolated from Output A; shares same supply and thermal path.
8	V_CC+	Positive supply rail - accepts 3–30 V; quiescent current independent of voltage magnitude.

Key Features

Feature	Design Value
Internal frequency compensation	Enables stable unity-gain operation without external components - reduces BOM count and layout sensitivity.
Rail-to-rail input common-mode range	Includes ground reference - eliminates need for input bias resistors when amplifying grounded sensors.
Low input bias current (20 nA)	Minimizes voltage error across high-impedance sources (e.g., pH electrodes or piezoelectric sensors).
Automotive qualification (AEC-Q100)	Validated for Grade 2 (−40 °C to +105 °C) operation - meets reliability requirements for powertrain and chassis modules.
ESD robustness (HBM 300 V)	Withstands handling and assembly stress without protection diodes - simplifies board-level ESD design.

Applications

Engine Coolant Temperature Sensing

Brake Fluid Level Monitoring

Use Scenario: Amplifies low-voltage output of NTC thermistor in engine bay, conditioned for microcontroller ADC input.

IC Role / Device Role / Timing Role: Dual op amp configured as precision non-inverting amplifier (Channel A) and comparator with hysteresis (Channel B).

Use Value: 2 mV offset ensures ≤0.2 °C measurement error at 100× gain; rail-to-rail input allows direct thermistor grounding.

Use Scenario: Detects capacitance change in fluid-level probe and generates digital alert signal for dashboard display.

IC Role / Device Role / Timing Role: Channel A acts as transimpedance amplifier for AC-excited probe; Channel B serves as window comparator.

Use Value: 1.1 MHz bandwidth supports 10–100 kHz excitation frequencies; 40 mA output drives indicator LED directly.

Body Control Module Window Lift Interface

Seat Position Feedback Conditioning

Use Scenario: Interfaces potentiometer-based window position sensor to MCU, rejecting noise from adjacent motor drivers.

IC Role / Device Role / Timing Role: Channel A performs low-pass filtering and gain; Channel B buffers reference voltage for ratiometric scaling.

Use Value: 100 dB CMRR rejects PWM noise from window motor; 0.7 mA/channel quiescent current minimizes battery drain.

Use Scenario: Conditions analog output of Hall-effect seat position sensor for safety-critical occupancy detection.

IC Role / Device Role / Timing Role: Dual amplifier implements differential amplification and offset correction in single-supply configuration.

Use Value: Input bias current <20 nA prevents loading of high-Z Hall sensor; AEC-Q100 qualification ensures functional safety compliance.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual operational amplifier applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
LM2904YDT	Identical pinout and electrical specs; enhanced ESD rating (HBM 2 kV vs. 300 V) and tighter offset voltage (1 mV max).	Preferred for new designs requiring higher robustness in manufacturing or harsher EMC environments.	Select LM2904YDT if system-level ESD testing exceeds IEC 61000-4-2 Level 3; otherwise LM358YDT remains cost-optimized for legacy-compliant modules.
TSV912IYDT	Higher GBW (8 MHz), lower noise (14 nV/√Hz), but reduced output drive (30 mA) and narrower supply range (2.7–5.5 V).	Suitable only for low-voltage, high-speed signal chains (e.g., camera focus control), not 12 V/24 V automotive subsystems.	Choose TSV912IYDT only when bandwidth >1 MHz and noise <20 nV/√Hz are mandatory; LM358YDT remains appropriate for general-purpose 5–30 V analog front-ends.

Compared with LM2904YDT, LM358YDT trades ESD margin and offset precision for broader supply compatibility (up to 30 V) and proven field reliability in mature platforms; versus TSV912IYDT, it sacrifices speed and noise performance to maintain compatibility with legacy 12 V/24 V power domains and industrial temperature stability.

FAQ

Is LM358YDT pin-compatible with standard LM358 variants?

Yes - LM358YDT uses the industry-standard SO8 footprint and identical pinout to LM358DT and LM358ADT. All share Pin 1 (Output A), Pin 2 (Inverting Input A), Pin 3 (Non-inverting Input A), Pin 4 (GND), Pin 5 (Non-inverting Input B), Pin 6 (Inverting Input B), Pin 7 (Output B), and Pin 8 (V_CC+). No PCB redesign is needed for drop-in replacement in non-automotive designs.

What is the maximum capacitive load LM358YDT can drive without oscillation?

LM358YDT remains stable with ≤100 pF capacitive load at unity gain, as verified by phase margin >40° in Figure 18 of the datasheet. For loads >100 pF (e.g., long cables or ADC input caps), a series resistor (≥100 Ω) between output and load is required to isolate capacitance and preserve stability.

Does LM358YDT support true rail-to-rail output?

No - LM358YDT output swings from 0 V to (V_CC − 1.5 V) under load, not to the positive rail. At V_CC = 5 V, minimum high-level output is 3.5 V; at V_CC = 12 V, it is ≥10.5 V. This limitation arises from its NPN output stage and must be accounted for in ADC reference selection or comparator thresholds.

Can LM358YDT be used as a comparator?

Yes - though not optimized for speed, LM358YDT functions reliably as a slow comparator (response time ~1.5 µs) when one input stays within the common-mode range. Its open-collector compatible output stage and internal clamping prevent latch-up, making it suitable for overtemperature alerts or fluid-level threshold detection where sub-µs response is unnecessary.
