Product details
Overview
LPV358IDDURE4 from Texas Instruments is a dual, rail-to-rail output, low-voltage (2.7 V to 5 V), low-power operational amplifier with 15 μA typical supply current per channel at 5 V, 152 kHz gain-bandwidth product, and input common-mode range extending to −0.2 V below VCC− - enabling ground-sensing in single-supply systems. It operates across −40°C to +125°C and is used in battery-powered sensor signal conditioning and portable medical device front-ends.
For engineers reviewing the LPV358IDDURE4 datasheet, LPV358IDDURE4 pinout, LPV358IDDURE4 application, or LPV358IDDURE4 equivalent, key selection criteria include its rail-to-rail output swing (VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ), stable operation with 1000 pF capacitive load, and guaranteed performance over extended temperature range without derating.
Technical Context
The LPV358IDDURE4 implements a CMOS input stage with rail-to-rail output stage, supporting true single-supply operation down to 2.7 V while maintaining low input bias current (≤50 nA) and low input offset voltage (≤11 mV over −40°C to +125°C). Its internal biasing enables full input common-mode range (−0.2 V to VCC+ − 0.8 V) and eliminates crossover distortion.
It achieves 152 kHz unity-gain bandwidth with only 15 μA per amplifier at 5 V, delivering a high speed-power ratio. The device is internally compensated and remains stable driving up to 1000 pF directly, eliminating need for external isolation resistors in capacitive-load applications such as ADC driver or filter stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5 V - supports direct connection to Li-ion battery (3.0–3.7 V) or regulated 3.3 V/5 V rails without level-shifting. |
| Supply Current (per channel) | 15 μA typical at 5 V - enables multi-year battery life in always-on sensor nodes with dual-channel signal path. |
| Gain-Bandwidth Product | 152 kHz - sufficient for DC-coupled instrumentation, low-frequency active filters, and precision transducer amplification. |
| Rail-to-Rail Output Swing | VCC+ − 3.5 mV / VCC− + 90 mV at 100 kΩ - maximizes dynamic range in 3.3 V systems, preserving >99% of available voltage headroom. |
| Input Common-Mode Range | −0.2 V to VCC+ − 0.8 V - allows direct sensing of signals referenced to ground or negative offsets in single-supply configurations. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, industrial control, and high-reliability embedded monitoring. |
| ESD Protection | 2000-V HBM, 200-V MM, 1000-V CDM - reduces risk of field failure during handling and PCB assembly in high-volume manufacturing. |

| 3 | IN+ A | Non-inverting input of Amplifier A - matched to IN− A; enables differential or single-ended sensing with ground reference. |
| 4 | VCC− | Negative supply rail - connects to system ground in single-supply operation; serves as return path for both amplifiers. |
| 5 | IN+ B | Non-inverting input of Amplifier B - independent channel; identical electrical specs to Amplifier A. |
| 6 | IN− B | Inverting input of Amplifier B - fully isolated from Channel A; supports dual-path signal processing without crosstalk. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Higher supply current (180 μA/channel), wider supply range (2.7 V–5.5 V), same pinout but not qualified to 125°C. | Not suitable for extended-temperature automotive or industrial environments; better for cost-sensitive consumer designs where power is less constrained. | Select LMV358IDR only if higher speed (1 MHz GBW) is required and 125°C operation is unnecessary. |
| TLV2372IDR | Lower supply current (1 μA/channel), lower GBW (150 kHz), same −40°C to +125°C rating, but input offset voltage higher (±3 mV typ vs ±7 mV max for LPV358IDDURE4). | Preferred for ultra-low-power wake-up circuits; less suitable for precision DC-coupled amplification due to higher VIO drift. | Choose TLV2372IDR when sub-μA quiescent current dominates design priority and offset drift is mitigated via calibration. |
Compared with LMV358IDR and TLV2372IDR, LPV358IDDURE4 uniquely balances ultra-low power (15 μA), extended temperature qualification (−40°C to +125°C), and rail-to-rail output performance - making it optimal for dual-channel, battery-constrained, high-reliability embedded sensing where both efficiency and robustness are mandatory.

FAQ
What is the maximum operating temperature range for LPV358IDDURE4?
The LPV358IDDURE4 is specified for continuous operation from −40°C to +125°C, verified per JEDEC JESD22-A108. This extended temperature grade makes it suitable for under-hood automotive, industrial motor control, and high-ambient embedded systems where standard commercial-grade op-amps would fail.
Does LPV358IDDURE4 support true single-supply operation with input signals at ground potential?
Yes. LPV358IDDURE4 features an input common-mode voltage range of −0.2 V to VCC+ − 0.8 V, allowing direct connection of ground-referenced sensors (e.g., thermistors, strain gauges) without external level-shifting circuitry - a key enabler for simplified single-supply signal chains.
Can LPV358IDDURE4 drive a 1000 pF capacitive load without oscillation?
Yes. The LPV358IDDURE4 is explicitly characterized and guaranteed stable with up to 1000 pF capacitive load on its output, per datasheet Figure 14 and Section 7.5. This eliminates the need for isolation resistors in ADC driver, active filter, or cable-driving applications - simplifying layout and improving signal integrity.
What is the typical supply current of LPV358IDDURE4 at 3.3 V operation?
At 3.3 V supply and 25°C, LPV358IDDURE4 draws approximately 13.5 μA per channel (27 μA total), based on linear interpolation of the 2.7 V (12 μA/ch) and 5 V (15 μA/ch) ICC curves in Figure 1. This ultra-low current enables multi-year operation in energy-constrained IoT endpoints.
Is LPV358IDDURE4 pin-compatible with other dual op-amps in SOIC-8 or VSSOP-8 packages?
LPV358IDDURE4 uses the standard VSSOP-8 (DDU) pinout defined for dual op-amps (OUT A, IN− A, IN+ A, V−, IN+ B, IN− B, OUT B, V+). It is pin-compatible with LMV358, TLV2372, and MCP6002 in VSSOP-8, but not with SOIC-8 variants due to different footprint and thermal pad configuration.
