Texas Instruments LM358TPX/NOPB

Overview

LM358TPX/NOPB from Texas Instruments is a dual, low-power, internally frequency-compensated operational amplifier designed for single-supply operation from 3 V to 32 V (or ±1.5 V to ±16 V). It delivers 1 MHz unity-gain bandwidth, 100 dB open-loop DC voltage gain, 2 mV input offset voltage, and rail-to-ground output swing-enabling direct sensing of signals referenced to ground in battery-powered sensor interfaces and industrial signal conditioning circuits.

For engineers reviewing the LM358TPX/NOPB datasheet, LM358TPX/NOPB pinout, LM358TPX/NOPB application, or LM358TPX/NOPB equivalent, key selection considerations include its ground-sensing input common-mode range, 500 μA supply current per amplifier, SOIC-8 packaging, single-supply compatibility, and verified performance across 0°C to 70°C ambient temperature.

Technical Context

The LM358TPX/NOPB integrates two independent PNP-input op-amps with class-A/B output stages, enabling both sourcing and sinking of up to 40 mA while maintaining stable operation under capacitive loads ≤50 pF. Its bias network delivers supply-current independence across 3 V–32 V, and its input stage accepts common-mode voltages down to ground-even when powered by a single rail.

Each amplifier features internally compensated unity-gain stability, differential input voltage tolerance exceeding supply rails, and output voltage swing within 20 mV of ground (at V+ = 5 V, RL = 10 kΩ). The device operates without external compensation and supports direct-coupled DC applications without crossover distortion.

FAQ

What is the maximum operating temperature range for LM358TPX/NOPB?

The LM358TPX/NOPB is rated for operation from 0°C to +70°C ambient temperature. This commercial-grade specification aligns with the LM358-N family's intended use in non-military, non-automotive industrial and consumer electronics where extended temperature ranges are not required. Full electrical performance-including input offset voltage, gain, and output swing-is guaranteed across this range per TI's SNOSBT3J datasheet.

Does LM358TPX/NOPB support true rail-to-rail output?

The LM358TPX/NOPB does not provide rail-to-rail output swing on the positive side-it swings up to ~26 V at V+ = 30 V-but it does deliver rail-to-ground output, sinking to within 20 mV of GND at V+ = 5 V with 10 kΩ load. This ground-swing capability is explicitly enabled by its PNP input stage and class-A/B output architecture, making it suitable for single-supply systems where low-side referencing is critical.

Can LM358TPX/NOPB be used with a 3.3-V supply?

Yes, LM358TPX/NOPB operates reliably from 3 V to 32 V single supply, including standard 3.3-V logic rails. At 3.3 V, it maintains 1 MHz unity-gain bandwidth, 500 μA supply current per amplifier, and ground-swing output (within ~50 mV of GND). Its input common-mode range extends from 0 V to V+ −1.5 V, allowing direct interface with 3.3-V sensors and microcontroller ADC references.

What is the input bias current specification for LM358TPX/NOPB?

The LM358TPX/NOPB exhibits a typical input bias current of 45 nA at 25°C (max 250 nA over full temperature range), due to its PNP differential input stage. This current flows *out* of both input terminals and remains essentially constant across supply voltage variations-a key enabler for high-impedance sensor interfaces where bias-induced voltage drop must be minimized.

Is LM358TPX/NOPB pin-compatible with other dual op-amps like NE5532 or TL072?

No, LM358TPX/NOPB is not pin-compatible with NE5532 or TL072. While all three are dual op-amps in 8-pin packages, their pinouts differ: LM358TPX/NOPB follows the industry-standard SOIC-8 op-amp configuration (GND on Pin 4, V+ on Pin 8), whereas NE5532 uses Pin 4 as V− and Pin 8 as V+, and TL072 places V− on Pin 4 and V+ on Pin 8 but has different internal topology and bias requirements. Direct substitution requires PCB redesign.
