Product details
Overview
LPV358D from Texas Instruments is a dual, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power (15 μA per amplifier at 5 V) operational amplifier optimized for space-constrained, battery-powered systems. It delivers 152 kHz gain-bandwidth product, ±0.2 V to VCC+ − 0.8 V input common-mode range, and rail-to-rail output swing within 3.5 mV of VCC+ and 90 mV of VCC− at 100-kΩ load - enabling precision signal conditioning in portable sensor interfaces and low-power active filters.
For engineers reviewing the LPV358D datasheet, LPV358D pinout, LPV358D application, or LPV358D equivalent, this page provides verified technical context, SOIC-8 package layout, real-world design meaning of key specs (e.g., 15 μA supply current, 152 kHz GBW, −40°C to 85°C operation), and two validated alternative op-amps with documented functional trade-offs for low-voltage analog front-ends.
Technical Context
The LPV358D implements a CMOS input stage with rail-to-rail output capability using complementary push-pull output transistors, enabling full dynamic range utilization in single-supply 2.7-V systems. Its input common-mode range extends 0.2 V below ground and 0.8 V below VCC+, supporting direct sensing of near-ground signals without level-shifting.
It achieves stable operation with capacitive loads up to 1000 pF and maintains ≥71° phase margin at 22-pF load - critical for driving ADC input buffers or long PCB traces. The device exhibits no crossover distortion and is characterized across −40°C to 85°C, meeting industrial temperature requirements without derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - enables direct operation from single-cell Li-ion (3.0–3.7 V) or 3.3-V logic rails without regulation. |
| Supply Current (per amp) | 15 μA typical at 5 V - supports >1-year battery life in always-on sensor nodes drawing <30 μA total. |
| Gain-Bandwidth Product | 152 kHz - sufficient for anti-aliasing filters at ≤10-kHz sampling rates and DC-coupled instrumentation amplifiers. |
| Input Offset Voltage | 7 mV typical (25°C, 5 V) - sets baseline accuracy for mV-level signal amplification without trimming. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100-kΩ - preserves >99% of full-scale range for 12-bit ADC interfacing. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows direct connection of grounded sensors (e.g., thermistors, bridge outputs) without bias resistors. |
| Operating Temperature | −40°C to +85°C - qualified for industrial control, automotive cabin modules, and outdoor IoT endpoints. |
Pinout & Package
LPV358D is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, 3.9-mm width, and JEDEC MS-012AC footprint - compatible with automated SMT assembly and legacy board layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives high-impedance loads (≥100 kΩ) with rail-to-rail swing; avoid >1000-pF capacitive loading without isolation resistor. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance CMOS node; keep trace short and guard against noise coupling in precision circuits. |
| 3 | IN+ A | Non-inverting input of Amplifier A - same impedance as IN− A; use matched trace lengths when used in differential configurations. |
| 4 | VCC− | Negative supply rail (typically GND) - connect directly to low-impedance ground plane; decouple with 100-nF ceramic capacitor near pin. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically identical to IN+ A; independent channel enables dual-path signal conditioning. |
| 6 | IN− B | Inverting input of Amplifier B - isolated from Amplifier A inputs; crosstalk rejection >100 dB at 1 kHz ensures channel independence. |
| 7 | OUT B | Amplifier B output - fully independent output stage; can drive separate loads or be cascaded with Amplifier A. |
| 8 | VCC+ | Positive supply rail (2.7–5 V) - power source for both amplifiers; shared supply requires careful decoupling to prevent inter-channel coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers usable output voltage within 3.5 mV of VCC+ and 90 mV of VCC−, maximizing dynamic range in single-supply systems. |
| Low quiescent current | 15 μA per amplifier at 5 V enables multi-year operation on coin-cell batteries in wireless sensor nodes. |
| No crossover distortion | CMOS output stage eliminates dead-zone nonlinearity, preserving signal fidelity in audio and sensor signal paths. |
| Stable with 1000-pF load | Eliminates need for external isolation resistors when driving ADC input capacitors or long cables. |
| ESD robustness | 2000-V HBM rating protects against handling damage during manual assembly and field service. |

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 |
|---|---|---|---|
| LMV358DR | Higher supply current (180 μA vs. 15 μA), wider GBW (1 MHz), but same SOIC-8 package and pinout. | Better for higher-speed signal chains (>100 kHz), less suitable for ultra-low-power designs. | Select LMV358DR only when speed outweighs battery life; LPV358D remains optimal for sub-200-kHz, sub-30-μA systems. |
| MCP6022-I/SN | Lower input offset (250 μV vs. 7 mV), higher GBW (10 MHz), but 170 μA supply current and different pinout (non-pin-compatible). | Preferred for precision DC-coupled amplification where offset dominates error budget. | Choose MCP6022-I/SN for <1-mV offset requirements; redesign PCB for pinout mismatch - LPV358D offers best balance of power, cost, and performance in general-purpose low-voltage use. |
Compared with LMV358DR and MCP6022-I/SN, the LPV358D uniquely delivers 15 μA supply current with verified rail-to-rail output and −40°C to 85°C operation in SOIC-8 - making it the lowest-power drop-in option for existing LPV358 footprints where speed is secondary to energy efficiency.

FAQ
What is the maximum operating temperature range for the LPV358D?
The LPV358D is specified for operation from −40°C to +85°C. This industrial-grade temperature range is confirmed in the official Texas Instruments datasheet (SLOS433I, Section "Recommended Operating Conditions") and applies to all SOIC-8 packaged variants including LPV358D. It does not support the extended −40°C to 125°C range offered by the LPV358ID variant.
Does the LPV358D support true rail-to-rail input operation?
No, the LPV358D features rail-to-rail *output* but not rail-to-rail *input*. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V, meaning it accepts signals 0.2 V below ground and up to 0.8 V below the positive rail. This allows ground-referenced sensor inputs but excludes direct VCC+ or negative-voltage signals without external level shifting.
Can the LPV358D drive a 1000-pF capacitive load without instability?
Yes - the LPV358D is explicitly characterized for stable operation with capacitive loads up to 1000 pF, as stated in the "Features" section of the TI datasheet. This eliminates the need for series isolation resistors when driving ADC input capacitors, sample-and-hold circuits, or long PCB traces, simplifying layout and reducing component count.
What is the typical supply current of the LPV358D at 3.3 V?
While the datasheet specifies 15 μA per amplifier at 5 V, the supply current scales approximately linearly with supply voltage. At 3.3 V, typical supply current is ~10 μA per amplifier (≈15 μA × 3.3/5), resulting in ~20 μA total for both channels - verified by Figure 1 ("Supply Current vs Supply Voltage") in the LPV358 datasheet, which shows ICC ≈ 10 μA at 3.3 V for the dual configuration.
Is the LPV358D pin-compatible with the LMV358 series?
Yes - the LPV358D shares identical SOIC-8 pinout and pin functions with the LMV358DR and LMV358D. Both devices use the same 1–8 pin mapping (OUT A, IN− A, IN+ A, VCC−, IN+ B, IN− B, OUT B, VCC+), enabling direct replacement in existing designs where lower supply current and rail-to-rail output are beneficial - provided system-level validation confirms stability under the new operating point.
