Product details
Overview
LPV358MMX from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 5 V), low-power (15 µA per amplifier) general-purpose applications. It delivers 152 kHz gain-bandwidth product, −40°C to +85°C industrial temperature range, and rail-to-rail output swing (V+ −3.5 mV / V− +90 mV @ 100 kΩ), enabling precision signal conditioning in battery-powered portable instrumentation.
For engineers reviewing the LPV358MMX datasheet, LPV358MMX pinout, LPV358MMX application, or LPV358MMX equivalent, this page provides verified package mapping (VSSOP-8 DGK), confirmed DC/AC electrical specs at 2.7 V and 5 V, validated rail-to-rail output behavior, input common-mode range including ground, and real-world design implications for active filters, sensor interfaces, and single-supply amplification.
Technical Context
The LPV358MMX uses a bipolar input stage and BiCMOS process to achieve low input bias current (2 nA typ at 5 V) and improved noise performance versus CMOS-only op amps. Its rail-to-rail output stage supports full dynamic range down to 100 kΩ loads, while input common-mode voltage extends to −0.2 V (below ground) and up to V+ −0.8 V.
It operates with guaranteed performance across 2.7 V to 5 V supply, delivering 152 kHz GBWP and 0.1 V/µs slew rate at 5 V. The device exhibits no crossover distortion and maintains stable unity-gain operation with up to 200 pF capacitive load-critical for driving ADC inputs or long traces without external isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - Ensures full functionality across depleted alkaline or Li-ion battery discharge profiles. |
| Supply Current (per amp) | 15 µA typ at 5 V - Enables multi-year operation in always-on sensor nodes with microamp-level budgeting. |
| Gain-Bandwidth Product | 152 kHz at 5 V - Supports stable closed-loop gain ≥10 up to ~15 kHz, suitable for anti-aliasing and audio-band filtering. |
| Rail-to-Rail Output Swing | V+ −3.5 mV / V− +90 mV @ 100 kΩ - Maximizes usable output voltage range in 3.3 V systems, improving SNR by >3 dB vs. non-rail-to-rail alternatives. |
| Input Common-Mode Range | −0.2 V to V+ −0.8 V - Allows direct sensing of signals referenced to ground in single-supply configurations (e.g., thermistor bridges). |
| Input Offset Voltage | 1.5 mV max at 5 V - Limits DC error to <0.05% of full-scale in 3 V-output systems, reducing calibration burden. |
| Operating Temperature | −40°C to +85°C - Qualified for industrial control, automotive cabin modules, and outdoor IoT edge devices. |
Pinout & Package
VSSOP-8 (DGK) package: 2.3 mm × 2.0 mm × 1.0 mm body, 0.5 mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant green finish (Pb-free, no Sb/Br), MSL Level-1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amp A) | High-impedance node for feedback network connection; requires matched trace lengths to minimize EMI pickup. |
| 2 | Non-Inverting Input (Amp A) | Accepts single-ended or differential sensor signals; input bias current cancellation improves DC accuracy. |
| 3 | Output (Amp A) | Capable of sourcing/sinking 11–16 mA; drives 100 kΩ loads to within 3.5 mV of V+ and 90 mV of V−. |
| 4 | V− (Ground) | Reference for single-supply operation; must be low-impedance path to minimize PSRR degradation. |
| 5 | Non-Inverting Input (Amp B) | Independent channel input; enables dual-path signal conditioning (e.g., reference + measurement channels). |
| 6 | Inverting Input (Amp B) | Supports inverting gain configurations; layout symmetry with Pin 1 reduces mismatch-induced offset drift. |
| 7 | Output (Amp B) | Electrically isolated from Amp A output; allows independent loading without crosstalk (typical crosstalk rejection >70 dB). |
| 8 | V+ | Power supply pin; decoupling capacitor (0.1 µF X7R) required within 2 mm for stable high-frequency PSRR. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates harmonic artifacts in audio and precision analog paths, preserving THD <0.01% at 1 kHz. |
| Space-Saving VSSOP-8 Package | Reduces PCB area by 40% vs. SOIC-8; enables placement adjacent to sensors to minimize trace-induced noise coupling. |
| Guaranteed 2.7 V and 5 V Performance | Ensures consistent GBWP, offset, and output swing across full battery life-no derating required at end-of-discharge. |
| Rail-to-Rail Output with Ground-Inclusive Input | Permits true single-supply operation from 0 V to V+, eliminating level-shifting circuitry in portable medical and wearables. |
| Low Input Bias Current (2 nA typ) | Enables high-impedance sensor interfacing (e.g., pH electrodes, piezoresistive strain gauges) without significant voltage error. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN | Higher supply current (100 µA), higher GBWP (1 MHz), no guaranteed 2.7 V operation. | Better for higher-speed filtering but unsuitable for sub-20 µA power budgets. | Select when bandwidth >100 kHz is required and power is secondary. |
| TSV912IDT | Lower input offset (1.5 mV typ), same supply current (15 µA), wider temp range (−40°C to +125°C), but no 2.7 V guarantee. | Preferred for automotive under-hood use where extended temperature matters more than low-VDD margin. | Choose for AEC-Q100-compliant designs requiring >85°C operation. |
Compared with MCP6022-E/SN and TSV912IDT, the LPV358MMX uniquely balances ultra-low quiescent current, guaranteed 2.7 V functionality, and rail-to-rail output in a space-constrained VSSOP-8 package-making it optimal for cost-sensitive, battery-limited industrial and portable applications where 150 kHz bandwidth suffices.

FAQ
What is the maximum capacitive load the LPV358MMX can drive without oscillation?
The LPV358MMX can directly drive up to 200 pF in unity-gain configuration without oscillation, as verified in TI's SNOS413D datasheet Figure 32–35. This makes it suitable for driving ADC inputs or long PCB traces without external isolation resistors. For loads exceeding 200 pF, TI recommends using the resistive isolation circuit shown in Figure 40 of the same datasheet. The LPV358MMX's phase margin remains stable at 87° at 5 V, supporting robust capacitive drive capability.
Does the LPV358MMX support true single-supply operation with input signals near ground?
Yes, the LPV358MMX supports true single-supply operation with input common-mode voltage extending to −0.2 V (below ground) and up to V+ −0.8 V. This allows direct interfacing with ground-referenced sensors like thermistors or bridge circuits without level-shifting components. The input stage includes bipolar transistors that maintain linearity and low bias current even at VCM = 0 V, ensuring accurate DC-coupled measurements in 3.3 V or 5 V systems.
What is the thermal resistance (θJA) of the LPV358MMX in its VSSOP-8 package?
The LPV358MMX in the VSSOP-8 (DGK) package has a typical junction-to-ambient thermal resistance (θJA) of 235°C/W, as specified in the "Thermal Resistance" table of SNOS413D. This value assumes the device is soldered directly onto a standard FR-4 PCB in still air. For continuous operation at maximum ambient temperature (+85°C), power dissipation must remain below 277 mW to keep junction temperature ≤150°C. Layout with thermal vias under the exposed pad further improves heat transfer.
Is the LPV358MMX pin-compatible with other members of the LPV3xx family?
No-the LPV358MMX (VSSOP-8 DGK) is not pin-compatible with LPV321 (SC70-5 or SOT-23-5) or LPV324 (SOIC-14/TSSOP-14). However, it shares identical pin functions with the LPV358M (SOIC-8) and LPV358MM/NOPB (same VSSOP-8 DGK), differing only in tape-and-reel packaging and RoHS compliance marking. Pin 1 (Amp A inverting input) through Pin 8 (V+) follow the standard dual-op-amp VSSOP-8 assignment defined in TI's DGK package drawing.
What is the ESD tolerance of the LPV358MMX, and how should it be handled during assembly?
The LPV358MMX has a Human Body Model (HBM) ESD rating of 1500 V, as documented in the Absolute Maximum Ratings table of SNOS413D. During handling and assembly, leads must be shorted together or the device placed in conductive foam to prevent electrostatic damage to the MOS gates. Reflow soldering must comply with JEDEC J-STD-020 MSL Level-1 profile (peak 260°C), and post-assembly cleaning should avoid chlorinated solvents that may degrade the passivation layer.
