Product details
Overview
LPV358MM/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), −40°C to +85°C industrial temperature range, and rail-to-rail output swing of V+ −3.5 mV / V− + 90 mV at 100 kΩ load - enabling precision signal conditioning in portable medical sensors and handheld instrumentation.
For engineers reviewing the LPV358MM/NOPB datasheet, LPV358MM/NOPB pinout, LPV358MM/NOPB application, or LPV358MM/NOPB equivalent, key selection criteria include its verified micropower operation under 2.7-V supply, bipolar-input noise performance (146 nV/√Hz at 1 kHz), input common-mode range extending to V− −0.2 V, and SOIC-8/VSSOP-8 package compatibility for space-constrained analog front-ends.
Technical Context
The LPV358MM/NOPB employs a bipolar input stage and BiCMOS process to achieve low input bias current (2–60 nA over temperature) and high output drive capability (11–16 mA sinking, 2–16 mA sourcing). Its rail-to-rail output architecture supports full dynamic range in single-supply configurations down to 2.7 V, while the input common-mode voltage range includes ground - critical for sensor interfacing near 0 V.
It operates stably with capacitive loads up to 200 pF in unity-gain configuration and features no crossover distortion. The device is specified across both 2.7-V and 5-V supplies, with DC parameters including 1.5–10 mV input offset voltage and 50–71 dB CMRR over 0 V to V+ −0.8 V common-mode range.

| 2 | IN− A | Inverting input for channel A - connects to feedback network in inverting amplifier or active filter. |
| 3 | IN+ A | Noninverting input for channel A - interfaces directly with grounded-sense sensor outputs. |
| 4 | V− | Negative supply rail - tied to GND in single-supply systems; enables true 0-V input operation. |
| 5 | IN+ B | Noninverting input for channel B - used for differential sensing or independent signal path. |
| 6 | IN− B | Inverting input for channel B - accepts feedback or reference voltage for second amplifier stage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-power, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN | Higher supply current (250 µA), higher GBW (1 MHz), lower input offset (250 µV typ) | Better for higher-speed sensor interfaces (>100 kHz), but reduces battery life in always-on devices | Select when speed outweighs power; avoid for sub-100-µA system budgets |
| TLV2462IDR | Lower supply current (550 µA), wider supply range (2.7–6 V), rail-to-rail I/O (not just output) | Enables true rail-to-rail input in single-supply designs where VCM must reach V+; higher noise (22 nV/√Hz) | Choose when input voltage range must extend to V+; not suitable for ultra-low-noise sensor front-ends |
Compared with MCP6022-I/SN and TLV2462IDR, LPV358MM/NOPB uniquely balances sub-20-µA quiescent current, 152-kHz bandwidth, and verified rail-to-rail output - making it optimal for cost-sensitive, battery-constrained applications where moderate speed and ultra-low power are co-prioritized.

FAQ
What is the maximum capacitive load LPV358MM/NOPB can drive without oscillation?
The LPV358MM/NOPB is stable driving up to 200 pF in unity-gain configuration, as confirmed in the datasheet's capacitive load tolerance section. This applies to both SOIC-8 and VSSOP-8 packages. For loads exceeding 200 pF, TI recommends adding a series isolation resistor (e.g., 100 Ω–1 kΩ) between the output and capacitor to restore phase margin. The LPV358MM/NOPB's internal compensation is optimized for this behavior, and no external compensation components are required below 200 pF.
Does LPV358MM/NOPB support true single-supply operation with input voltages at ground?
Yes. The LPV358MM/NOPB features an input common-mode voltage range that extends to V− −0.2 V, allowing direct connection to grounded-sense elements like NTC thermistors or current-sense shunts in single-supply systems. Its bipolar input stage ensures stable operation and low input bias current even at 0 V input. This capability is explicitly validated across the −40°C to +85°C temperature range and at both 2.7 V and 5 V supply voltages.
What is the typical input offset voltage for LPV358MM/NOPB at room temperature and 5 V supply?
The typical input offset voltage for LPV358MM/NOPB is 7 mV at TJ = 25°C and V+ = 5 V, with a guaranteed maximum of 10 mV over the full −40°C to +85°C operating range. This value is measured differentially across both channels and reflects the device's micropower optimization - trading some DC precision for ultra-low supply current. For applications requiring tighter offset, TI recommends using external trimming or selecting a higher-precision variant like the LPV821, though at higher current cost.
Can LPV358MM/NOPB be used in a dual-supply configuration?
Yes. The LPV358MM/NOPB is fully specified for dual-supply operation, supporting ±1.35 V to ±2.5 V (i.e., total supply of 2.7 V to 5 V). Its input common-mode range and rail-to-rail output swing remain functional with symmetric or asymmetric dual rails. The device's bipolar input stage ensures consistent performance regardless of supply topology, and all key AC/DC specifications - including GBW, noise, and slew rate - are validated under dual-supply conditions in the official datasheet.
Is LPV358MM/NOPB pin-compatible with other dual op amps in SOIC-8 or VSSOP-8 packages?
No. While LPV358MM/NOPB shares the industry-standard SOIC-8 (D) and VSSOP-8 (DGK) footprints, its pinout is specific to the LPV3xx-N family and differs from common dual op amps like the LM358 or TL072. Specifically, LPV358MM/NOPB uses pins 1/7 for outputs and 2/3/5/6 for inputs - unlike LM358's output/input arrangement. Direct replacement requires PCB layout revision unless using TI's LPV358-specific footprint. Always verify pin mapping before board design.
