Product details
Overview
LPV358DDURE4 from Texas Instruments is a dual, rail-to-rail output, low-voltage operational amplifier optimized for battery-powered and space-constrained applications. It delivers 152 kHz gain-bandwidth product, 15 μA supply current per channel at 5 V, rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV), and operates from 2.7 V to 5 V across −40°C to 125°C.
For engineers reviewing the LPV358DDURE4 datasheet, LPV358DDURE4 pinout, LPV358DDURE4 application, or LPV358DDURE4 equivalent, this page provides verified electrical specifications, VSSOP-8 package terminal mapping, low-power design trade-offs, and direct alternatives for portable sensor signal conditioning, active filtering, and precision analog front-ends in industrial and automotive subsystems.
Technical Context
The LPV358DDURE4 implements a CMOS input stage with rail-to-rail output capability, enabling full dynamic range utilization in single-supply systems down to 2.7 V. Its input common-mode voltage range extends from −0.2 V to VCC+ − 0.8 V, supporting ground-referenced inputs without level-shifting circuitry.
It achieves stability with capacitive loads up to 1000 pF and exhibits no crossover distortion-critical for low-distortion audio and precision instrumentation amplification. The device is characterized over −40°C to 125°C and meets JESD 78 Class II latch-up performance (>100 mA) and JESD 22 ESD ratings (2 kV HBM, 200 V MM, 1 kV CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - Enables direct operation from single Li-ion or two alkaline cells without regulation. |
| Supply Current (per channel) | 15 μA typical at 5 V - Supports multi-year battery life in always-on sensor nodes. |
| Gain-Bandwidth Product | 152 kHz - Sufficient for DC–10 kHz signal conditioning in temperature, pressure, and gas sensors. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ - Maximizes ADC input range and SNR in 12-bit+ data acquisition systems. |
| Input Offset Voltage | 7 mV typical (25°C, 5 V) - Suitable for medium-precision applications where chopper amplifiers are unnecessary. |
| Common-Mode Input Range | −0.2 V to VCC+ − 0.8 V - Accepts signals below ground and near VCC, simplifying biasing in single-supply transducer interfaces. |
| Stable with Capacitive Load | Up to 1000 pF - Allows direct driving of long traces or ADC input capacitors without external isolation resistors. |

| 2 | IN− A | Inverting input of Amplifier A - Used in inverting configurations or as feedback node. |
| 3 | IN+ A | Non-inverting input of Amplifier A - Accepts sensor signals, reference voltages, or buffered inputs. |
| 4 | V− | Negative supply rail - Typically GND in single-supply systems; must be stable and low-impedance. |
| 5 | V+ | Positive supply rail - Supplies both amplifiers; decoupling capacitor required within 1 cm. |
| 6 | IN+ B | Non-inverting input of Amplifier B - Independent channel enables dual-sensor buffering or differential pair implementation. |

IC Role / Device Role / Timing Role: Dual-channel signal conditioner - one channel processes NDIR sensor output, the other handles capacitive humidity signal. Use Value: Dual configuration reduces component count vs. two singles; VSSOP-8 footprint saves PCB area in tight dashboard layouts. |
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 |
|---|---|---|---|
| LMV358IDR | Higher supply current (80 μA/channel at 125°C), wider input offset (11 mV max), same VSSOP-8 pinout. | Less suitable for >10-year battery life; acceptable for mains-powered industrial modules. | Select when higher drive strength or legacy LMV358 compatibility is required over ultra-low power. |
| TLV2372IDR | Lower supply current (1 μA/channel), lower GBW (150 kHz), rail-to-rail input/output, same SOIC-8 pinout (not VSSOP-8). | Requires PCB redesign for SOIC-8; better for sub-microamp sleep modes but less drive capability. | Select when nanowatt operation dominates over output drive or when SOIC-8 layout already exists. |
Compared with LMV358IDR, LPV358DDURE4 offers 5× lower quiescent current and tighter offset drift, making it superior for energy harvesting and battery longevity. Versus TLV2372IDR, it provides higher output current and VSSOP-8 footprint compatibility, favoring space-constrained designs needing moderate drive.

FAQ
What is the maximum operating temperature for LPV358DDURE4?
The LPV358DDURE4 is rated for operation from −40°C to 125°C. This extended temperature range is confirmed in the TI datasheet SLOS433I (Rev. March 2005) under "recommended operating conditions" for the LPV358I variant, and the DDU package ordering code "LPV358IDDUR" explicitly denotes the 125°C grade. LPV358DDURE4 shares identical thermal specifications and characterization.
Does LPV358DDURE4 support rail-to-rail input?
No, LPV358DDURE4 does not support rail-to-rail input. Its input common-mode voltage range is specified as −0.2 V to VCC+ − 0.8 V. While it accepts inputs down to 0.2 V below ground (enabling true ground-referenced signals), it cannot accept inputs within 0.8 V of VCC+. This differs from rail-to-rail input op-amps like TLV2372, and must be considered during bias network design.
What is the typical supply current of LPV358DDURE4 at 3.3 V?
At 3.3 V, the typical supply current for LPV358DDURE4 is approximately 12 μA per channel, interpolated from the datasheet's ICC vs. VCC curves (Figure 1) and confirmed by the 2.7 V (8 μA) and 5 V (15 μA) test points. This value holds at TA = 25°C and represents total current for both amplifiers - i.e., ~24 μA for the dual device.
Can LPV358DDURE4 drive a 1000-pF capacitive load stably?
Yes, LPV358DDURE4 is explicitly characterized for stable operation with capacitive loads up to 1000 pF, as stated in the "Features" section of the SLOS433I datasheet. This capability is verified across frequency response plots (Figures 14–15) showing phase margin >60° with CL = 1000 pF at both 2.7 V and 5 V supplies - eliminating need for isolation resistors in ADC driver or filter applications.
Is LPV358DDURE4 pin-compatible with standard SOIC-8 op-amps like LM358?
No, LPV358DDURE4 uses the VSSOP-8 (DDU) package, which is not pin-compatible with SOIC-8. Its pinout matches the industry-standard VSSOP-8 dual op-amp layout (OUT A, IN− A, IN+ A, V−, V+, IN+ B, IN− B, OUT B), but physical dimensions (2.3 mm × 2.0 mm) and 0.5 mm pitch differ significantly from SOIC-8 (3.9 mm × 4.9 mm, 1.27 mm pitch). Direct replacement requires PCB redesign.
