Product details
Overview
LMV358AIDGKT from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V) operation in space-constrained systems. It delivers ±1 mV input offset voltage, 1 MHz unity-gain bandwidth, 70 µA per channel quiescent current, and rail-to-rail output swing - enabling precision signal conditioning in battery-powered smoke detectors, wearable devices, and low-side current sensing circuits.
For engineers reviewing the LMV358AIDGKT datasheet, LMV358AIDGKT pinout, LMV358AIDGKT application, or LMV358AIDGKT equivalent, key selection criteria include capacitive-load drive stability up to 500 pF, resistive open-loop output impedance for robust layout tolerance, –40°C to 125°C extended temperature operation, and verified EMI/RFI filtering for noisy industrial environments.
Technical Context
The LMV358AIDGKT implements a P-channel/N-channel complementary input stage to eliminate phase reversal during overdrive while maintaining rail-to-rail input common-mode range (V– – 0.1 V to V+ – 1 V). Its class-AB output stage achieves 20 mV rail-to-rail swing into 10 kΩ loads across full supply and temperature range.
Designed for single-supply operation, it features integrated RFI/EMI rejection filtering, unity-gain stability without external compensation, and a resistive open-loop output impedance (~1.2 kΩ at 1 MHz) that simplifies stabilization with high capacitive loads - a critical advantage over conventional op amps in sensor interface and ADC driver applications.
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, including battery-powered wearables and IoT edge nodes. |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤10 mV error in 10× gain configurations, critical for accurate low-side current sensing. |
| Unity-Gain Bandwidth | 1 MHz - supports stable amplification of signals up to ~100 kHz in closed-loop configurations with adequate phase margin. |
| Quiescent Current | 70 µA per channel - allows dual-op-amp functionality in ultra-low-power applications such as motion detectors with multi-year battery life. |
| Rail-to-Rail Output Swing | Within 20 mV of rails (RL = 10 kΩ) - maximizes dynamic range when driving SAR ADCs with 3.3 V reference voltages. |
| Capacitive Load Drive | Stable with ≥500 pF - eliminates need for isolation resistors in PCB traces or LCD bias networks, reducing BOM count. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive modules, HVAC controllers, and industrial motor drives. |
Pinout & Package
DGK package: 8-pin VSSOP (3 mm × 4.9 mm), thermally enhanced for compact layouts and improved power dissipation in dual-amplifier configurations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Output, Channel A | Class-AB buffered output capable of sourcing/sinking ±40 mA; swings within 20 mV of V+ or V– under 10 kΩ load. |
| 2 (–IN A) | Inverting Input, Channel A | High-impedance node (10 pA bias current); accepts signals down to V– – 0.1 V without phase reversal. |
| 3 (+IN A) | Noninverting Input, Channel A | Complementary P/N input pair enables rail-to-rail common-mode range and EMI immunity. |
| 4 (V–) | Negative Supply / Ground | Reference for single-supply operation; must be connected directly to system ground or negative rail. |
| 5 (+IN B) | Noninverting Input, Channel B | Independent input for second signal path; no crosstalk (channel separation >100 dB at 10 kHz). |
| 6 (–IN B) | Inverting Input, Channel B | Matches Channel A electrical characteristics; supports dual-sensor interfaces or differential-to-single-ended conversion. |
| 7 (OUT B) | Output, Channel B | Electrically identical to OUT A; enables independent gain stages or active filter sections on same die. |
| 8 (V+) | Positive Supply | Accepts 2.5–5.5 V; internal ESD protection and supply filtering reduce sensitivity to board-level noise. |
Key Features
| Feature | Design Value |
|---|---|
| Resistive Open-Loop Output Impedance | ~1.2 kΩ at 1 MHz - enables stable operation with >1 nF capacitive loads without series isolation resistors. |

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 | SOIC-8 package; higher RθJA (147.4°C/W vs 201.2°C/W for DGK); identical electrical specs. | Better thermal performance required in high-density layouts; SOIC preferred for wave-soldered industrial boards. | Select LMV358IDR for manual assembly or legacy SOIC footprints; LMV358AIDGKT for space-constrained VSSOP designs. |
| TLV9002IDSGR | Lower input offset (±0.75 mV), higher GBW (1.5 MHz), but higher IQ (125 µA/ch); different pinout. | Higher precision and speed needed in active filters or fast-settling data acquisition; not pin-compatible. | Choose TLV9002IDSGR only when offset or bandwidth requirements exceed LMV358AIDGKT capabilities; redesign PCB required. |
Compared with LMV358IDR, LMV358AIDGKT offers superior thermal resistance in compact layouts but requires rework for SOIC-based legacy designs; versus TLV9002IDSGR, it trades bandwidth and offset for 44% lower quiescent current and guaranteed 500 pF capacitive-load stability - making it optimal for always-on battery systems.

FAQ
What is the maximum capacitive load the LMV358AIDGKT can drive without instability?
The LMV358AIDGKT is characterized for stable operation with ≥500 pF capacitive load, thanks to its resistive open-loop output impedance and internal compensation. This eliminates the need for external isolation resistors in typical PCB trace or sensor cable scenarios. For loads exceeding 1 nF, verify phase margin using the manufacturer's SPICE model or bench testing with actual layout parasitics.
Does the LMV358AIDGKT support true rail-to-rail input operation?
The LMV358AIDGKT provides rail-to-rail *output* swing but not full rail-to-rail *input*. Its input common-mode range extends to V– – 0.1 V and V+ – 1 V, enabling single-supply use with signals referenced to ground. For inputs near V+, TI recommends limiting voltage to < V+ – 1 V to maintain specified offset and CMRR performance per the Electrical Characteristics table.
What is the overload recovery time of the LMV358AIDGKT, and why does it matter?
The LMV358AIDGKT has an overload recovery time of approximately 850 ns. This parameter defines how quickly the output returns to linear operation after saturation - critical in fast transient detection circuits like smoke alarm ionization amplifiers or motor fault monitors where delayed recovery could mask short-duration events.
Can the LMV358AIDGKT be used in photodiode transimpedance applications?
Yes - the LMV358AIDGKT is validated for single-supply photodiode amplifiers, leveraging its 10 pA input bias current, 30 nV/√Hz input voltage noise, and rail-to-rail output to maximize dynamic range. Application note SBOS923I includes a complete design example with 3.3 V supply, 0–10 µA input, and 50 kHz bandwidth using external feedback components.
Is the LMV358AIDGKT pin-compatible with older LMV358 variants?
The LMV358AIDGKT is functionally and pin-compatible with the legacy LMV358 family in the same DGK (VSSOP-8) package. However, the "A" suffix denotes improved specifications: tighter input offset (±1 mV vs ±3 mV), lower noise, and enhanced EMI rejection. No PCB changes are required when upgrading from non-A versions in the same footprint.
