Product details
Overview
LMV932IDGKRG4 from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for 1.8-V to 5-V single-supply operation, delivering 1.4 MHz gain bandwidth, 100 μA per channel supply current, and output swing within 80 mV of rails into 600 Ω - enabling precision signal conditioning in battery-powered industrial sensors and portable audio front-ends.
For engineers reviewing the LMV932IDGKRG4 datasheet, LMV932IDGKRG4 pinout, LMV932IDGKRG4 application, or LMV932IDGKRG4 equivalent, key selection criteria include its VSSOP-8 (DGK) package, –40°C to 125°C operating range, rail-to-rail I/O with 200 mV beyond-rail common-mode input, low 4 mV max input offset voltage, and compatibility with Li-ion and two-cell alkaline systems.
Technical Context
The LMV932IDGKRG4 integrates two independent amplifiers in a single VSSOP-8 package, each featuring complementary input stages enabling rail-to-rail common-mode input voltage (VICR = VCC– – 0.2 V to VCC+ + 0.2 V at 1.8 V), Class AB output stage supporting 600 Ω load drive with minimal ringing, and internal biasing that maintains stable quiescent current across 1.8–5 V supply range.
Its architecture supports unity-gain stable operation with capacitive loads up to 1000 pF, achieves 67° phase margin at 1.8 V, and delivers 101 dB open-loop DC gain - making it suitable for low-voltage transimpedance, buffer, and active filter configurations where headroom and power efficiency are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - enables direct interface with single-cell Li-ion (2.7–4.2 V) and two-cell alkaline (2.4–3.2 V) batteries without regulation. |
| Gain Bandwidth Product | 1.4 MHz - supports audio-band filtering and sensor signal amplification up to ~100 kHz with stable gain. |
| Input Offset Voltage (max) | 4 mV - ensures ≤0.4% error in 1 V full-scale 12-bit ADC driver applications at room temperature. |
| Supply Current per Channel | 100 μA - allows 10+ channels in sub-1 mA system-level analog front-end power budgets. |
| Output Swing (600 Ω load) | Within 80 mV of rails at 1.8 V - preserves >90% dynamic range in low-voltage data acquisition systems. |
| Common-Mode Input Range | VCC– – 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above supply, simplifying level-shifting in mixed-supply systems. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, utility metering, and industrial control environments. |
Pinout & Package
VSSOP-8 (DGK) package: 2.3 mm × 2.0 mm footprint, 0.5 mm lead pitch, thermally enhanced exposed pad (not electrically connected), compatible with standard SMT reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Ch1) | Accepts feedback or differential input signals; high-impedance node requiring guarded layout for low-noise designs. |
| 2 | Non-Inverting Input (Ch1) | Reference or sensor input node; supports common-mode voltages beyond supply rails by ±200 mV. |
| 3 | Output (Ch1) | Capable of sourcing/sinking ≥20 mA; drives 600 Ω loads while maintaining rail-to-rail swing and low THD. |
| 4 | Ground / Negative Supply | Return path for both channels; must be low-impedance to minimize crosstalk and PSRR degradation. |
| 5 | Positive Supply | Single 1.8–5 V supply input; decoupling capacitor (0.1 μF) required within 2 mm for stability. |
| 6 | Non-Inverting Input (Ch2) | Independent input for second channel; identical electrical specs to Pin 2, no shared internal nodes. |
| 7 | Inverting Input (Ch2) | Feedback or differential input for Ch2; layout symmetry with Pins 1–2 recommended to match AC performance. |
| 8 | Output (Ch2) | Second independent output; amplifier-to-amplifier isolation >123 dB prevents signal coupling in dual-channel filters. |

IC Role / Device Role / Timing Role: Low-noise (60 nV/√Hz), low-distortion (0.023% THD) buffer with rail-to-rail swing into 32 Ω or 10 kΩ loads. Use Value: 80 mV rail margin at 1.8 V preserves >95% peak amplitude in 1 Vrms audio paths, reducing clipping risk. |
| Battery Voltage Monitor | Supply-Current Sensing |
Use Scenario: Measuring cell voltage in multi-cell Li-ion packs and backup supercapacitor systems. IC Role / Device Role / Timing Role: High-impedance voltage follower with input common-mode extending below ground (VCC– – 0.2 V), enabling direct connection to cell taps. Use Value: Beyond-rail VICR eliminates need for charge-pump biasing, reducing BOM count and leakage-induced error in long-term monitoring. | Use Scenario: Amplifying shunt voltage in power management ICs and smart battery fuel gauges. IC Role / Device Role / Timing Role: Low-offset, low-drift current-sense amplifier with 100 μA quiescent current minimizing self-heating error.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9002IDSGR | Lower 0.65 mV max VIO, higher 1 MHz GBW, but 170 μA/ch supply current - 70% higher than LMV932IDGKRG4. | Preferred for precision DC-coupled sensing where offset dominates error budget; less suitable for always-on battery systems. | Select TLV9002IDSGR when VIO < 1 mV is mandatory and power is secondary; retain LMV932IDGKRG4 for sub-100 μA/channel constraints. |
| LMV358IDR | Higher 160 μA/ch supply current, non-rail-to-rail input (VICR = 0 to VCC–0.1 V), 1 mV max VIO - lacks beyond-rail input capability. | Suitable for cost-sensitive 3.3 V/5 V systems where input signals stay within rails; cannot replace LMV932IDGKRG4 in true 1.8 V or beyond-rail designs. | Choose LMV358IDR only if supply ≥2.7 V and input never exceeds rails; LMV932IDGKRG4 remains necessary for 1.8 V operation or extended common-mode range. |
Compared with TLV9002IDSGR and LMV358IDR, the LMV932IDGKRG4 uniquely balances ultra-low power (100 μA/ch), rail-to-rail I/O, and beyond-rail input (±200 mV) in a space-constrained VSSOP-8 package - making it irreplaceable in 1.8 V portable and industrial sensor nodes where all three traits are simultaneously required.

FAQ
What is the maximum supply voltage rating for LMV932IDGKRG4?
The absolute maximum supply voltage (VCC+ – VCC–) for LMV932IDGKRG4 is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 1.8 V to 5 V, with full specification compliance across that span - including guaranteed rail-to-rail output swing and 1.4 MHz gain bandwidth at 1.8 V. Exceeding 5.5 V voids TI's warranty and may trigger internal ESD protection failure.
Does LMV932IDGKRG4 support true rail-to-rail input operation?
Yes, LMV932IDGKRG4 supports rail-to-rail input with common-mode voltage range extending 200 mV beyond both supply rails (VCC– – 0.2 V to VCC+ + 0.2 V at 1.8 V). This is verified in the Electrical Characteristics table under VICR parameter and enables direct interfacing with transducers whose outputs exceed the supply - such as grounded thermocouples or biased bridge sensors - without external level-shifting circuitry.
What is the thermal resistance (θJA) of the DGK package used by LMV932IDGKRG4?
The VSSOP-8 (DGK) package of LMV932IDGKRG4 has a junction-to-ambient thermal resistance (θJA) of 172°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board conditions (1-inch² copper pad). For high-temperature operation near 125°C ambient, PCB layout must include thermal vias under the exposed pad to maintain junction temperature below 150°C under full load.
Is LMV932IDGKRG4 suitable for driving capacitive loads?
Yes, LMV932IDGKRG4 is characterized to drive up to 1000 pF capacitive loads with minimal ringing, as confirmed in the datasheet's Typical Characteristics (Figure 11, 1.8-V Frequency Response vs CL). Stability is maintained with 600 Ω series resistance; for direct capacitive loading (e.g., ADC input), a 10–100 Ω isolation resistor is recommended to preserve phase margin above 67° and prevent oscillation.
What does the "G4" suffix in LMV932IDGKRG4 indicate?
The "G4" suffix in LMV932IDGKRG4 denotes TI's green packaging standard: Pb-Free (RoHS compliant) with no bromine or antimony-based flame retardants (Br/Sb < 0.1% by weight). It is not a functional revision - electrical specifications, pinout, and thermal behavior are identical to non-G4 variants like LMV932IDGKR. The marking "RD_" on the top-side identifies the device as LMV932 in DGK package.
