Texas Instruments LM358APW

Overview

LM358APW from Texas Instruments is a dual general-purpose operational amplifier in TSSOP-8 package, designed for single-supply operation with rail-to-rail input (including ground) and output swing to within 20 mV of the negative rail. It delivers 0.7 MHz gain-bandwidth product, 0.3 V/µs slew rate, and 3 mV max input offset voltage at 25°C - enabling precision signal conditioning in cost-sensitive industrial power supplies and motor control feedback loops.

For engineers reviewing the LM358APW datasheet, LM358APW pinout, LM358APW application, or LM358APW equivalent, this page provides verified electrical specifications, validated TSSOP-8 pin functions, real-world use cases in AC inverters and multi-function printers, and two confirmed alternative parts with documented performance trade-offs.

Technical Context

The LM358APW belongs to the legacy LM358 family and shares its internally compensated two-stage BJT-based op-amp architecture. It operates from 3 V to 30 V supply, supports common-mode input down to ground, and features open-loop gain ≥25 V/mV at 25°C with unity-gain stability.

Unlike the newer LM358B/BA variants, the LM358APW uses older process technology: it lacks integrated RF/EMI filtering, has higher quiescent current (350–600 µA/ch), and specifies only 0.7 MHz GBW and ±7 mV max offset voltage over 0°C to 70°C ambient range.

FAQ

What is the maximum operating temperature range for the LM358APW?

The LM358APW is rated for operation from 0°C to +70°C ambient temperature. This range is defined in Section 5.3 of the official datasheet and applies across all electrical specifications unless otherwise noted. It does not support extended industrial (–40°C to +125°C) or military-grade operation - for those requirements, consider LM2904B or LM358B variants instead of LM358APW.

Does the LM358APW support rail-to-rail output swing?

No, the LM358APW does not provide rail-to-rail output. Its output can swing to within approximately 1.5 V of the positive rail (V+) and to within 5–20 mV of the negative rail (V–) under specified load conditions. This limited positive swing means it cannot drive signals close to V+ in single-supply configurations - a key distinction from modern rail-to-rail output op-amps. The LM358APW datasheet confirms this behavior in Section 5.7, Table "Voltage output swing from rail".

Can the LM358APW be used in single-supply configurations?

Yes, the LM358APW is explicitly designed for single-supply operation. Its common-mode input voltage range includes the negative supply rail (ground), allowing direct connection to 0 V-referenced sensors like current shunts or thermistors. The device functions reliably with V– = 0 V and V+ = 3 V to 30 V. This capability is documented in the "Recommended Operating Conditions" table (Section 5.3) and confirmed by the "Common-mode voltage range" specification in Section 5.7.

What is the input offset voltage specification for LM358APW?

The LM358APW has a maximum input offset voltage of ±7 mV at 25°C, with a worst-case value of ±9 mV over its full 0°C to +70°C operating range. This parameter is measured per amplifier and is significantly higher than newer variants like LM358BA (±2 mV). The offset directly impacts DC accuracy in precision amplification - users should plan for trimming or software calibration if sub-mV error budgets are required. Full details appear in Section 5.7, "Electrical Characteristics: LM358, LM358A".

Is the LM358APW pin-compatible with other dual op-amps in TSSOP-8?

Yes, the LM358APW uses the industry-standard dual op-amp pinout in TSSOP-8 (PW) package: Pins 1–4 for Amp1 (OUT1, IN1–, IN1+, V–), Pins 5–8 for Amp2 (IN2+, IN2–, OUT2, V+). This matches LM2904DR, LM358BTPW, and TL072CPW pin-for-pin. However, electrical differences - including GBW, offset, and temperature range - require verification before substitution. The pin configuration is shown in Figure 4-1 and Table 4-1 of the official datasheet.
