Product details
Overview
LP358D from Texas Instruments is a dual ultra-low-power operational amplifier optimized for battery-powered systems, featuring 54 µA typical supply current, 2 mV typical input offset voltage, and rail-to-rail input common-mode range extending to GND - enabling single-supply operation in portable instrumentation and LCD display bias circuits.
For engineers reviewing the LP358D datasheet, LP358D pinout, LP358D application, or LP358D equivalent, key selection criteria include its 3–32 V wide supply range, 70°C operating temperature limit, SOIC-8 package compatibility with LM358/LM2904 footprints, and verified performance in low-current sensor signal conditioning and power supply feedback loops.
Technical Context
The LP358D integrates two independent, unity-gain-stable op-amps with Darlington-source/emitter-follower output stages that maintain quiescent current independence from load current. Its input stage supports common-mode voltages from GND to VCC – 1.5 V, enabling direct interfacing with ground-referenced sensors.
It operates across 3 V to 32 V single or split supplies, delivering 100 kHz gain-bandwidth product and 50 V/ms slew rate while sustaining 7 mA sourcing / 4 mA sinking output drive at 25°C - balancing bandwidth, precision, and ultra-low power consumption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current (Typ) | 54 µA per amplifier - enables multi-year battery life in always-on portable devices |
| Input Offset Voltage (Typ) | 2 mV - ensures <1% error in 12-bit ADC front-end applications at room temperature |
| Input Bias Current (Typ) | 2 nA - permits high-impedance sensor interfaces (e.g., thermistors, pH electrodes) without significant offset drift |
| Common-Mode Input Range | GND to VCC – 1.5 V - allows direct connection of ground-referenced transducers without level-shifting circuitry |
| Output Swing (VOL/VOH) | 0.7 V (low) / 3.6 V (high) at 5 V supply - provides usable dynamic range for 3.3 V logic-compatible signal conditioning |
| Gain-Bandwidth Product | 100 kHz - sufficient for DC–10 kHz sensor amplification and power supply error amplification |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded systems including consumer electronics and industrial HMIs |
Pinout & Package
LP358D is housed in an 8-pin SOIC (D) package with 4.90 mm × 3.91 mm body size, JEDEC-standard footprint, and RoHS-compliant NiPdAu lead finish rated MSL Level-1 (unlimited reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives feedback networks or low-impedance loads up to 7 mA source / 4 mA sink |
| 2 | IN1− | Amplifier 1 inverting input - accepts differential signals or configured as summing node in active filters |
| 3 | IN1+ | Amplifier 1 noninverting input - connects to reference voltage or high-Z sensor outputs with minimal loading |
| 4 | GND | Analog ground reference - must be tied to system ground plane with low-inductance path to minimize noise coupling |
| 5 | IN2+ | Amplifier 2 noninverting input - electrically isolated from Channel 1; supports dual-sensor monitoring |
| 6 | IN2− | Amplifier 2 inverting input - used for inverting gain configurations or comparator hysteresis networks |
| 7 | OUT2 | Amplifier 2 output - independent output stage enables dual-channel signal processing without crosstalk |
| 8 | VCC | Positive supply rail - accepts 3–32 V; requires 0.1 µF ceramic bypass capacitor placed within 2 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low supply current | 54 µA per amplifier - reduces battery drain by >50% versus standard LM358 (250 µA), extending runtime in coin-cell devices |
| Ground-sensing inputs | Input common-mode includes GND - eliminates need for negative supply or level-shifting in single-supply sensor interfaces |
| Wide supply voltage range | 3 V to 32 V operation - supports both low-voltage IoT nodes and industrial 24 V control systems with one BOM item |
| LM358/LM2904 pin compatibility | SOIC-8 footprint match - enables drop-in replacement in legacy designs without PCB revision or layout changes |
| Robust ESD protection | ±2000 V HBM rating - withstands handling in standard assembly environments without special ESD controls |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Higher 250 µA typical supply current; 7 mV max input offset; wider –25°C to 85°C temp range | Better suited for cost-sensitive industrial controls where power efficiency is secondary to temperature range | Select LM358DR when extended temperature operation or higher output drive (20 mA) is required over ultra-low power |
| LP2904DR | Identical electrical specs but rated for –40°C to 85°C; same SOIC-8 package and pinout | Required for automotive cabin modules or outdoor equipment needing extended thermal qualification | Choose LP2904DR when full industrial temperature range is mandatory; LP358D remains optimal for commercial-grade portable devices |
Compared with LM358DR and LP2904DR, the LP358D delivers the lowest power consumption (54 µA) for battery-constrained applications while maintaining pin compatibility - making it the preferred choice for commercial portable electronics where 0°C–70°C operation suffices and milliamp-hour budgeting is critical.

FAQ
What is the maximum supply voltage for LP358D?
The LP358D supports a maximum supply voltage of 32 V, as specified in its Absolute Maximum Ratings table. Operation above this voltage risks permanent device damage. For reliable long-term use, TI recommends staying within the Recommended Operating Conditions range of 3 V to 32 V, with derating advised near thermal limits.
Is LP358D pin-compatible with LM358?
Yes, the LP358D is explicitly designed as a pin-compatible upgrade to the LM358 in SOIC-8 packaging. Both share identical pin numbering, function mapping, and footprint dimensions - allowing direct substitution in existing layouts without PCB modification or redesign effort.
What is the operating temperature range of LP358D?
The LP358D is characterized for operation from 0°C to 70°C ambient temperature, as confirmed in the Recommended Operating Conditions table. This commercial-grade range suits consumer electronics, portable instruments, and indoor industrial HMIs - distinct from the extended –40°C to 85°C range of the LP2904 variant.
Does LP358D support single-supply operation?
Yes, the LP358D fully supports true single-supply operation due to its input common-mode voltage range extending to GND and output swing capable of reaching within ~0.7 V of GND. This eliminates the need for dual supplies in sensor interface and signal conditioning applications.
What is the typical input offset voltage of LP358D?
The LP358D has a typical input offset voltage of 2 mV at 25°C, with a maximum of 4 mV under those conditions and up to 9 mV across the full 0°C to 70°C operating range. This precision enables accurate DC-coupled amplification in measurement systems where offset-induced errors must remain below 0.1%.
