Product details
Overview
LM258AWYPT 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. It features internal frequency compensation, 2 kV HBM ESD protection, and operates across -40 °C to +105 °C - widely used in sensor signal conditioning and industrial interface circuits.
For engineers reviewing the LM258AWYPT datasheet, LM258AWYPT pinout, LM258AWYPT application, or LM258AWYPT equivalent, key selection criteria include input offset voltage (2 mV max), supply current (0.7–1.2 mA), common-mode input range including ground, and automotive-grade qualification per AEC-Q100.
Technical Context
The LM258AWYPT integrates two independent high-gain op-amps with internal frequency compensation enabling stable unity-gain operation. Its input stage uses PNP transistors enabling input common-mode voltage down to ground and differential input range equal to full supply voltage.
Output stage supports rail-to-rail sinking (50 mA sink at 0.2 V) and sourcing (60 mA source at 2 V), with output swing from 0 V to (VCC+ − 1.5 V). Temperature-compensated biasing ensures stable 20 nA input bias current and 2 nA input offset current over operating temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 30 V - enables direct interfacing with 5 V logic and wide industrial rails without level-shifting. |
| Unity-Gain Bandwidth | 1.1 MHz - supports audio-frequency amplification and medium-speed sensor signal processing. |
| Large-Signal Voltage Gain | 100 dB - provides >100,000× open-loop gain for precision DC amplification and filtering. |
| Input Offset Voltage | 2 mV max - ensures ≤2 mV error at output under no-signal conditions, critical for low-level transducer amplification. |
| Supply Current per Amplifier | 0.35–0.6 mA - enables battery-powered or energy-constrained systems with dual-channel analog front-end. |
| Common-Mode Input Range | 0 V to (VCC+ − 1.5 V) - allows ground-referenced inputs and simplifies single-supply design without biasing networks. |
| Output Voltage Swing | 0 V to (VCC+ − 1.5 V) - delivers maximum dynamic range when driving ADCs or downstream logic with minimal headroom loss. |
Pinout & Package
TSSOP8 (Thin Shrink Small Outline Package), 8-pin, surface-mount, 3.0 mm × 4.4 mm body, 0.65 mm pitch, RoHS-compliant, automotive-grade qualified (AEC-Q100).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplifier 1 output node - drives external load or feedback network; capable of 60 mA source / 50 mA sink. |
| 2 | Inverting Input 1 | Negative input of Amp1 - accepts feedback or signal inversion path; input bias current 20 nA. |
| 3 | Non-inverting Input 1 | Positive input of Amp1 - reference point for gain configuration; common-mode range includes ground. |
| 4 | VCC− (GND) | Power return for both amplifiers - must be low-impedance; shared ground improves channel separation (120 dB). |
| 5 | Non-inverting Input 2 | Positive input of Amp2 - electrically isolated from Amp1; enables dual independent signal paths. |
| 6 | Inverting Input 2 | Negative input of Amp2 - supports separate feedback loop; matched input characteristics to Pin 2. |
| 7 | Output 2 | Amplifier 2 output node - identical drive capability to Pin 1; supports independent load or cascaded stages. |
| 8 | VCC+ | Positive supply rail - powers both amplifiers; supply rejection ratio 65–100 dB minimizes noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 2 (−40 °C to +105 °C) - certified for engine control, body electronics, and ADAS sensor interfaces. |
| ESD protection | 2 kV HBM - eliminates need for external transient suppression in board-level ESD-prone environments. |
| Rail-to-ground input | Input common-mode includes 0 V - enables direct connection of thermocouples, current-sense resistors, and other ground-referenced sensors. |
| Low quiescent current | 0.7 mA total (both amps @ 5 V) - extends battery life in portable instrumentation and remote monitoring nodes. |
| Channel separation | 120 dB @ 1–20 kHz - prevents crosstalk between dual channels in multi-sensor signal chains or stereo audio preamps. |

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 |
|---|---|---|---|
| LM2904VQDR | Higher input offset voltage (7 mV max), wider temp range (−40 °C to +125 °C), same TSSOP8 package. | Less suitable for precision DC amplification but better for high-temp under-hood use. | Select when ambient temperature exceeds +105 °C and offset tolerance >7 mV is acceptable. |
| TSV912IYDT | Higher GBW (8 MHz), lower input bias (1 pA), rail-to-rail I/O, but only 2.7–5.5 V supply range. | Optimized for low-voltage portable designs; not compatible with 12 V or 24 V industrial rails. | Select when system uses 3.3 V logic and requires faster settling or ultra-low input current. |
Compared with LM258AWYPT, LM2904VQDR trades precision for extended temperature margin, while TSV912IYDT offers speed and input performance at the cost of supply voltage flexibility - making LM258AWYPT optimal for cost-sensitive, wide-rail, automotive-qualified dual-op-amp applications.

FAQ
What is the maximum operating junction temperature for LM258AWYPT?
The absolute maximum junction temperature is 150 °C, with thermal resistance junction-to-ambient (RthJA) rated at 120 °C/W for the TSSOP8 package. Derating is required above +105 °C ambient; continuous operation at full load should maintain Tj ≤ 135 °C for reliability.
Does LM258AWYPT support rail-to-rail output swing?
LM258AWYPT provides output swing from 0 V to (VCC+ − 1.5 V) - it reaches ground but does not swing fully to VCC+. This enables true ground-referenced outputs in single-supply systems while maintaining adequate headroom for internal circuitry.
Is LM258AWYPT pin-compatible with standard LM258 variants?
Yes - LM258AWYPT shares identical pinout and electrical behavior with LM258WDT (SO8) and LM258WPT (TSSOP8), differing only in automotive qualification level and marking (K410). No PCB redesign is needed when upgrading to automotive-grade version.
Can LM258AWYPT be used as a comparator?
It is not recommended: the LM258AWYPT lacks internal hysteresis and has slow recovery from saturation (typ. 10 µs), causing oscillation and delayed response. Dedicated comparators like TS882IYDT are preferred for threshold detection applications.
