Product details
Overview
LPV358M/NOPB from Texas Instruments is a dual-channel, micropower, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5 V), battery-powered applications. It delivers 152 kHz gain-bandwidth product, 15 µA total supply current (7.5 µA per channel), rail-to-rail output swing (V+ −3.5 mV / V− +90 mV at 100 kΩ), and operates across −40°C to +85°C. It is used in portable sensor signal conditioning and low-power active filtering.
For engineers reviewing the LPV358M/NOPB datasheet, LPV358M/NOPB pinout, LPV358M/NOPB application, or LPV358M/NOPB equivalent, key selection criteria include micropower consumption under 20 µA, guaranteed rail-to-rail output performance at 2.7 V, input common-mode range extending to ground, and SOIC-8/VSSOP-8 package compatibility for space-constrained industrial and portable designs.
Technical Context
The LPV358M/NOPB employs a bipolar input stage and BiCMOS process for improved noise performance (146 nV/√Hz at 1 kHz) and higher output drive capability (±11 mA sinking/sourcing). Its architecture supports single-supply operation with input common-mode voltage range from −0.2 V to V+ − 0.8 V, enabling direct ground-referenced sensing.
It achieves stable unity-gain operation with up to 200 pF capacitive load without external compensation and exhibits no crossover distortion due to rail-to-rail output stage design. The device maintains 87° phase margin and 19 dB gain margin at 5 V, ensuring robust small-signal stability in precision DC and low-frequency AC applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, micropower, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN | Higher supply current (180 µA), higher GBWP (1 MHz), wider supply range (2.7–5.5 V) | Better suited for higher-speed sensor interfaces (>100 kHz), but reduces battery life by 12× vs LPV358M/NOPB | Select when bandwidth >500 kHz is required and power budget allows >100 µA per channel. |
| TSV632IST | Lower supply current (49 µA total), lower noise (42 nV/√Hz), same rail-to-rail I/O | Superior for low-noise precision instrumentation, but lacks −40°C to +85°C industrial temp grade (only −40°C to +85°C for some variants; verify specific part) | Prefer for noise-critical medical front-ends where temperature range aligns; confirm industrial-grade variant availability. |
Compared with MCP6022-I/SN and TSV632IST, LPV358M/NOPB offers the lowest quiescent current in its class while maintaining guaranteed −40°C to +85°C operation and proven stability with capacitive loads-making it optimal for long-life, space-constrained, industrial-grade portable electronics.

FAQ
What is the maximum capacitive load LPV358M/NOPB can drive without oscillation?
The LPV358M/NOPB is specified to remain stable with up to 200 pF capacitive load in unity-gain configuration without external compensation. This is verified per TI's characterization data in the SNOS413E datasheet Section 7.4.1. Exceeding this value requires isolation resistors or feedback network adjustments. LPV358M/NOPB's internal compensation ensures reliable operation in LCD bias, DAC output buffering, and sensor cable driving applications where moderate capacitance is present.
Does LPV358M/NOPB support true single-supply operation with input signals at 0 V?
Yes. LPV358M/NOPB features an input common-mode voltage range extending to −0.2 V (below ground) and up to V+ − 0.8 V, enabling direct interface with 0 V–referenced sensors like thermistors, RTDs, and bridge transducers in single-supply systems. This eliminates the need for external level-shifting circuitry. The LPV358M/NOPB's bipolar input stage ensures stable biasing and low offset drift across this range, as confirmed in Section 6.7 of the datasheet.
What is the typical supply current of LPV358M/NOPB at 2.7 V and 25°C?
At 2.7 V and 25°C, the typical supply current for LPV358M/NOPB is 12 µA (Section 6.5, IS parameter). This represents the combined current for both amplifiers. The datasheet specifies a maximum of 16 µA under these conditions, making LPV358M/NOPB among the lowest-power dual op amps qualified for industrial temperature range. This ultra-low current directly translates to extended runtime in energy-harvesting and coin-cell–powered applications.
Can LPV358M/NOPB be used in a dual-supply configuration?
Yes. LPV358M/NOPB supports dual-supply operation (e.g., ±1.35 V to ±2.5 V) as explicitly stated in Section 7.4 and Section 8.1 of the datasheet. Its input common-mode and output swing specifications are defined for both single- and dual-supply modes. When operated symmetrically, LPV358M/NOPB maintains rail-to-rail output swing relative to each rail and retains full functionality - ideal for legacy analog test equipment or mixed-signal systems requiring bipolar signal handling.
Is LPV358M/NOPB pin-compatible with other dual op amps in SOIC-8 or VSSOP-8 packages?
LPV358M/NOPB uses the industry-standard dual op amp pinout (pin 1 = OUT A, pin 2 = IN− A, pin 3 = IN+ A, pin 4 = V−, pin 5 = IN+ B, pin 6 = IN− B, pin 7 = OUT B, pin 8 = V+), matching LMV358, TLC272, and MCP6022. However, functional equivalence-including bandwidth, supply current, and input/output voltage ranges-must be verified per application. LPV358M/NOPB is not a drop-in replacement for higher-current or higher-speed parts without circuit revalidation.
