Product details
Overview
LM258WYPT from STMicroelectronics is a low-power dual operational amplifier in TSSOP8 package, designed for single-supply operation from 3 V to 30 V, with 1.1 MHz unity-gain bandwidth, 100 dB large-signal voltage gain, and rail-to-rail output swing down to 0 V (VCC− − 1.5 V). It features 2 kV HBM ESD protection, 20 nA input bias current, and 2 mV input offset voltage-enabling transducer signal conditioning and DC gain blocks in automotive-grade industrial sensors and 5 V logic-compatible interface circuits.
For engineers reviewing the LM258WYPT datasheet, LM258WYPT pinout, LM258WYPT application, or LM258WYPT equivalent, key selection criteria include its AEC-Q100 qualified automotive temperature range (−40 °C to +105 °C), TSSOP8 footprint compatibility, input common-mode range extending to ground, and guaranteed performance at 5 V supply without external level-shifting.
Technical Context
The LM258WYPT integrates two independent high-gain op-amps with internal frequency compensation, enabling stable unity-gain operation up to 1.1 MHz. Its input stage uses PNP transistors to achieve input common-mode voltage range down to ground and differential input voltage range equal to the full supply rail.
Output stage supports rail-to-rail sinking (down to 20 mV at 10 kΩ load) and sourcing (up to 60 mA), with thermal shutdown protection and infinite output short-circuit duration under ≤15 V supply. The device maintains 70 dB CMRR and 65 dB SVR across its operating temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - enables direct use with 5 V logic rails and higher-voltage industrial supplies without regulation. |
| Unity-Gain Bandwidth | 1.1 MHz - supports audio-frequency amplification and sensor signal conditioning up to ~100 kHz closed-loop. |
| Large-Signal Voltage Gain | 100 dB - provides ≥10⁵ open-loop gain for precision DC amplification with <0.1% error at 100× closed-loop gain. |
| Input Offset Voltage | 2 mV max - ensures ≤20 mV output error at unity gain, critical for low-level transducer outputs (e.g., thermocouples). |
| Input Bias Current | 20 nA typ - minimizes voltage drop across high-impedance sources (e.g., pH electrodes, photodiodes). |
| Output Swing (Low) | 20 mV min at 10 kΩ - allows true ground-referenced output in single-supply systems without negative rail. |
| ESD Protection | 2 kV HBM - meets automotive board-level robustness requirements per ISO 10605. |

| 5 | Non-inverting Input 2 | Independent input for second amplifier; electrically isolated from Amp1; same bias and offset specs as Pins 2–3. |
| 6 | Inverting Input 2 | Second amplifier's inverting node; supports AC/DC coupling; compatible with resistor networks up to 10 MΩ. |
| 7 | Output 2 | Second amplifier output; fully independent; identical drive capability and voltage swing to Pin 1. |
| 8 | VCC+ | Positive supply rail (3–30 V); powers both amplifiers; requires local 100 nF ceramic decoupling within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 2 (−40 °C to +105 °C), qualified per Q001/Q002 screening - suitable for engine control, body electronics, and ADAS sensor front-ends. |
| Single-supply operation | Input common-mode range includes ground; output swings to 0 V - eliminates need for split supplies in battery-powered or 5 V microcontroller systems. |
| Low power consumption | 0.7 mA total supply current at 5 V - enables always-on sensor interfaces with <3.5 mW quiescent dissipation per amplifier. |
| Input protection | Internal ESD diodes rated to 2 kV HBM - reduces external TVS requirements in harsh EMC environments (e.g., automotive CAN nodes). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2904WDT | Same SO8 package, identical pinout, but rated for −40 °C to +125 °C; 700 kHz GBW; 300 µV typical Vio. | Higher temp grade suits under-hood automotive; lower bandwidth limits audio/high-speed use; tighter offset benefits precision DC. | Select when extended temperature range or lower offset is prioritized over bandwidth. |
| MCP6022-E/SN | SO8, rail-to-rail input/output; 10 MHz GBW; 25 µA supply current; 250 µV Vio; not AEC-Q100 qualified. | Superior speed and input/output swing for active filters or fast-settling circuits; higher current draw; no automotive qualification. | Select for non-automotive designs requiring >1 MHz bandwidth and true rail-to-rail I/O. |
Compared with LM258WYPT, LM2904WDT offers wider temperature coverage and lower offset but reduced bandwidth, while MCP6022-E/SN delivers 9× higher speed and full rail-to-rail operation at the cost of higher supply current and no automotive qualification.

FAQ
Is LM258WYPT pin-compatible with standard LM258 variants?
Yes, LM258WYPT shares identical pinout and electrical behavior with LM258WDT (SO8) and LM258WST (MiniSO8), differing only in package (TSSOP8) and qualification level (AEC-Q100 Grade 2). All share the same 8-pin dual-op-amp topology, supply voltage range (3–30 V), and functional specifications per DocID9159 Rev 14.
What is the maximum capacitive load the LM258WYPT can drive without instability?
LM258WYPT remains stable driving up to 100 pF capacitive load in unity-gain configuration, as verified in Figure 17 (Phase Margin vs. Capacitive Load) of the datasheet. For loads >100 pF, a series isolation resistor (≥100 Ω) between output and capacitance is required to maintain ≥45° phase margin.
Does LM258WYPT support true rail-to-rail input?
No - LM258WYPT features input common-mode voltage range extending to ground (VCC−) but upper limit is VCC+ − 1.5 V. It does not support rail-to-rail input; however, its ability to accept inputs at ground and deliver outputs down to 20 mV makes it functionally compatible with rail-to-rail systems using 5 V or higher supplies.
Can LM258WYPT be used as a comparator?
Yes, though not optimized for speed: LM258WYPT operates as an open-loop comparator with propagation delay ~1.2 µs (typical) at 5 V supply. Input common-mode range must stay within −0.3 V to VCC+ − 1.5 V; output saturates near rails. For high-speed or precision threshold detection, dedicated comparators (e.g., TS882) are recommended.
