Product details
Overview
LMV358AIDGKR from Texas Instruments is a dual-channel, low-voltage (2.5 V to 5.5 V), rail-to-rail output operational amplifier optimized for space-constrained, battery-powered systems. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 70 µA per channel quiescent current, and operates across –40°C to 125°C - enabling precision signal conditioning in smoke detectors, wearable devices, and low-side current sensing.
For engineers reviewing the LMV358AIDGKR datasheet, LMV358AIDGKR pinout, LMV358AIDGKR application, or LMV358AIDGKR equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world implementation guidance for single-supply photodiode amplifiers and current-sense circuits, and validated alternative options for design continuity.
Technical Context
The LMV358AIDGKR implements a P-channel/N-channel parallel input stage to extend common-mode range to within 100 mV of V– and avoid phase reversal under overdrive - critical for robust single-supply operation. Its resistive open-loop output impedance (1.2 kΩ at 1 MHz) enables stable driving of ≥500 pF capacitive loads without external compensation.
This dual op amp features integrated RFI/EMI filtering, unity-gain stability, and rail-to-rail output swing to within 20 mV of either supply rail (at 10 kΩ load). It supports low-voltage analog front-ends where dynamic range preservation and EMI resilience are essential - such as sensor interfaces in HVAC controls and EPOS terminals.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct integration into 3.3 V and 5 V systems without level-shifting or LDO overhead |
| Input Offset Voltage | ±1 mV (typ) - ensures <100 µV error in 100 mV shunt-based current sensing at room temperature |
| Unity-Gain Bandwidth | 1 MHz - supports closed-loop gain ≥10 up to ~100 kHz with adequate phase margin (>76°) |
| Quiescent Current | 70 µA per channel - allows dual-amplifier operation on microamp-level power budgets (e.g., coin-cell wearables) |
| Output Swing | Within 20 mV of rails (RL = 10 kΩ) - maximizes ADC input dynamic range in 3.3 V or 5 V data acquisition |
| Input Bias Current | ±10 pA (typ) - minimizes voltage error across high-impedance sources like photodiodes or thermistors |
| Operating Temperature | –40°C to 125°C - qualified for industrial and automotive cabin-adjacent applications (e.g., motor control feedback) |
Pinout & Package
Dual operational amplifier in 8-pin SOIC (D) package, 4.9 mm × 6.0 mm body size, surface-mount, leaded, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; rail-to-rail swing supports full-scale ADC interfacing |
| 2 | –IN A | Inverting input, channel A - used in transimpedance, inverting gain, or differential configurations |
| 3 | +IN A | Noninverting input, channel A - accepts reference voltages or high-impedance sensor signals |
| 4 | V– | Negative supply or ground - shared return path for both amplifiers; must be low-impedance for noise immunity |
| 5 | +IN B | Noninverting input, channel B - independent input for second signal path (e.g., dual-sensor monitoring) |
| 6 | –IN B | Inverting input, channel B - enables simultaneous processing of two analog channels without cross-talk |
| 7 | OUT B | Amplifier B output - identical performance to OUT A; supports dual-path signal conditioning |
| 8 | V+ | Positive supply - powers both amplifiers; decoupling capacitor required near pin for stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings to within 20 mV of V+ or V– at 10 kΩ load - preserves >99% of available voltage headroom for ADCs |
| Resistive open-loop output impedance | 1.2 kΩ at 1 MHz - simplifies stabilization with capacitive loads up to 500 pF without added series resistance |
| No phase reversal | Guaranteed under overdrive conditions - prevents latch-up or erroneous output polarity in transient events |
| Integrated RFI/EMI filter | Rejects >100 dB interference at 1 GHz (EMIRR+) - improves reliability in noisy environments like motor drives |
| Low input bias current | 10 pA typical - reduces offset error in high-Z sensor interfaces (e.g., pH electrodes, piezoelectric sensors) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail output op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358IDR | Same silicon, SOIC-8 package but no green/RoHS exemption - Pb-free, halogen-free, and qualified to same specs | Identical performance; preferred for new designs requiring full environmental compliance | Select LMV358IDR when RoHS-6 and REACH compliance are mandatory and legacy exemptions are unavailable |
| TLV2372IDR | Higher 3 MHz GBW, 190 µA/ch IQ, wider 2.7–16 V supply - not drop-in; requires layout review for supply and decoupling | Better for higher-speed filtering or wider supply ranges; unsuitable for <2.7 V or ultra-low-power use | Choose TLV2372IDR only if bandwidth >1 MHz or supply >5.5 V is required - not a direct replacement |
Compared with LMV358AIDGKR, LMV358IDR offers identical functionality with updated environmental compliance, while TLV2372IDR trades quiescent current for speed and voltage range - making it suitable only for designs that explicitly require those trade-offs.

FAQ
What is the maximum capacitive load the LMV358AIDGKR can drive stably?
The LMV358AIDGKR is characterized to drive ≥500 pF capacitive loads stably without external compensation, thanks to its resistive open-loop output impedance. At 1000 pF, phase margin remains >40° in unity-gain configuration. For loads exceeding 500 pF, TI recommends verifying stability with actual board parasitics and layout - the LMV358AIDGKR's architecture simplifies stabilization compared to conventional op amps.
Does the LMV358AIDGKR support true rail-to-rail input?
The LMV358AIDGKR does not provide rail-to-rail input - its common-mode input range extends to within 100 mV of V– and to within 1 V of V+, per the datasheet. This allows full negative-rail referencing in single-supply operation but requires input signals to stay below V+ – 1 V to maintain specified performance. The LMV358AIDGKR achieves rail-to-rail *output*, not input.
Can the LMV358AIDGKR be used in a single-supply photodiode amplifier?
Yes - the LMV358AIDGKR is explicitly validated in TI's datasheet for single-supply photodiode amplification (Figure 7-3), leveraging its low input bias current (10 pA), rail-to-rail output, and internal EMI filtering. With proper biasing (e.g., 100 mV reference), it converts 0–10 µA photocurrents into 0.1–3.2 V outputs at 3.3 V supply - making LMV358AIDGKR ideal for optical sensing in portable medical or IoT devices.
What is the overload recovery time of the LMV358AIDGKR?
The LMV358AIDGKR recovers from output saturation in approximately 850 ns, as measured under G = –10, 600 mVpp input overdrive. This fast recovery minimizes dead time in comparator-like or pulse-amplification roles. The value is consistent across temperature (–40°C to 125°C) and supply (2.5 V to 5.5 V), and is enabled by its class-AB output stage and optimized internal biasing - a key advantage over older micropower op amps.
Is the LMV358AIDGKR pin-compatible with the legacy LMV358 series?
Yes - the LMV358AIDGKR is pin-compatible with LMV358 variants in SOIC-8 (e.g., LMV358IDR, LMV358M), sharing identical pinout, footprint, and thermal pad absence. Electrical improvements include tighter offset (±1 mV vs ±3 mV), lower noise (30 nV/√Hz vs 45 nV/√Hz), and enhanced EMI rejection. No PCB changes are needed when upgrading from LMV358 to LMV358AIDGKR in existing SOIC-8 layouts.
