Product details
Overview
LMV932ID 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 80 mV output swing from rails into 600 Ω - used in battery-powered industrial metering and portable audio signal conditioning.
For engineers reviewing the LMV932ID datasheet, LMV932ID pinout, LMV932ID application, or LMV932ID equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail I/O performance at 1.8 V, thermal design data (θJA = 97°C/W), and validated alternatives for low-voltage op-amp selection in space-constrained embedded systems.
Technical Context
The LMV932ID integrates two independent amplifiers with complementary input stages enabling rail-to-rail common-mode input voltage range extending 200 mV beyond both supply rails. Its Class AB output stage supports stable driving of 600 Ω loads with 1000 pF capacitive load while maintaining ≥67° phase margin.
Each amplifier features matched input bias currents (≤75 nA) and low input offset voltage (max 7.5 mV), enabling precision DC-coupled sensing in single-supply configurations. The device operates across –40°C to +125°C without requiring external compensation components.
Key Specifications

|---|---|
| Supply Voltage Range | 1.8 V to 5 V - enables direct interface with Li-ion or two-cell alkaline batteries without level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - supports audio-band filtering and sensor signal amplification up to ~100 kHz closed-loop bandwidth. |
| Input Offset Voltage | Max 7.5 mV - ensures ≤0.75% error in 1-V full-scale DC measurements at room temperature. |
| Supply Current per Channel | 100 μA typical at 1.8 V - allows >10-year battery life in always-on monitoring nodes powered by CR2032 cells. |
| Output Swing (600 Ω) | 80 mV from rails - preserves >90% dynamic range in 1.8-V systems, critical for ADC input drive. |
| Common-Mode Input Range | VCC− −0.2 V to VCC+ +0.2 V - accepts signals below ground or above supply, simplifying sensor interfacing. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial energy metering applications. |
Pinout & Package
LMV932ID is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Thermal resistance θJA = 97°C/W enables operation at full rating in still-air environments up to +85°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load directly; rail-to-rail swing supports full 1.8-V headroom. |
| 2 | IN− A | Inverting input for Amplifier A - high-impedance node (IIB ≤75 nA); requires matched trace routing for precision DC gain. |
| 3 | IN+ A | Non-inverting input for Amplifier A - accepts signals from VCC− −0.2 V to VCC+ +0.2 V without phase reversal. |
| 4 | VCC− | Negative supply rail - connects to system ground in single-supply configuration; decoupling capacitor required. |
| 5 | VCC+ | Positive supply rail - accepts 1.8 V to 5 V; internal ESD protection rated to 2 kV HBM. |
| 6 | IN+ B | Non-inverting input for Amplifier B - electrically isolated from Amplifier A; enables dual-channel independent signal paths. |
| 7 | IN− B | Inverting input for Amplifier B - matched to Pin 2 for common-mode rejection in differential configurations. |
| 8 | OUT B | Amplifier B output - identical AC/DC specs to Pin 1; supports independent gain staging or buffer duplication. |
Key Features

| 200 mV beyond-rail input range | Accepts transducer outputs that swing slightly below ground (e.g., thermocouples, bridge sensors) without clamping. |
| Stable with 1000 pF capacitive load | Eliminates need for isolation resistors when driving ADC input capacitors or long PCB traces. |
| –40°C to +125°C operation | Qualified for deployment in automotive cabin modules and utility meter enclosures without derating. |
Applications
| Industrial Energy Metering | Automotive Cabin Sensors |
|---|---|
Use Scenario: High-accuracy current sensing in smart electricity meters using shunt resistors and 16-bit delta-sigma ADCs.

Use Value: 80 mV output swing at 1.8 V preserves 12-bit ENOB; rail-to-rail input accommodates ±50 mV shunt signals without external biasing. | Use Scenario: Occupancy detection via analog IR sensor output conditioning in vehicle seatbelt or climate control modules. IC Role / Device Role / Timing Role: Low-power transimpedance amplifier converting photodiode current to voltage, followed by gain-stage amplification. Use Value: 100 μA/channel supply current extends battery backup life; 1.4 MHz GBW supports fast response to occupancy events. |
| Portable Audio Line Drivers | Battery Voltage Monitoring |

IC Role / Device Role / Timing Role: Rail-to-rail output buffer isolating DAC output from variable headphone impedance (16–32 Ω). Use Value: 600 Ω drive capability ensures <1% THD at 10 mW into 32 Ω; 0.022% THD at 1 kHz minimizes audible distortion. | Use Scenario: Precision battery voltage measurement in medical wearables using 3.7-V LiPo cells with 2.8–4.2 V operating range. IC Role / Device Role / Timing Role: Unity-gain buffer feeding ADC input, rejecting noise from switching regulators powering the system MCU.

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 |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 μA/channel), wider GBW (6.4 MHz), no beyond-rail input capability. | Better suited for higher-speed active filters but increases power consumption 5.5× over LMV932ID. | Select TLV2462IDR only when closed-loop bandwidth >500 kHz is required and power budget permits. |
| OPA2314AIDR | Lower input offset (1.8 mV max), lower noise (25 nV/√Hz), but higher quiescent current (150 μA/channel). | Preferred for precision instrumentation where offset drift matters more than ultra-low power. | Choose OPA2314AIDR when DC accuracy dominates over battery life - e.g., medical sensor calibration circuits. |
Compared with TLV2462IDR and OPA2314AIDR, LMV932ID delivers the lowest power consumption and unique beyond-rail input capability at the expense of higher offset and lower speed - making it optimal for cost-sensitive, battery-constrained industrial monitoring where signal bandwidth stays below 100 kHz.

FAQ
What is the maximum supply voltage rating for LMV932ID?
The absolute maximum supply voltage (VCC+ – VCC−) for LMV932ID is 5.5 V. Operating continuously above 5 V risks permanent damage. The recommended operating range is 1.8 V to 5 V, with full electrical specifications guaranteed across this span - including rail-to-rail output swing and 1.4 MHz gain bandwidth at 1.8 V.
Does LMV932ID support true rail-to-rail input operation?
Yes, LMV932ID 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). This allows direct interfacing with sensors whose outputs fall slightly below ground or exceed the positive rail - confirmed in the datasheet's VICR specification table for all supply voltages (1.8 V, 2.7 V, 5 V).
What is the thermal resistance (θJA) of LMV932ID in its SOIC-8 package?
The junction-to-ambient thermal resistance (θJA) of LMV932ID in the SOIC-8 (D) package is 97°C/W, as specified in the Absolute Maximum Ratings table. This value assumes standard JEDEC 2-layer board layout per JESD51-7; actual thermal performance improves with added copper pour and thermal vias under the exposed pad (if present) - though the D package has no exposed pad.
Can LMV932ID drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes, LMV932ID delivers rail-to-rail output swing into 600 Ω loads: at 1.8 V supply, output reaches within 80 mV of each rail (0.08 V and 1.72 V); at 5 V supply, it achieves within 160 mV (0.16 V and 4.84 V). These values are measured under standard test conditions (VO = 0.2 V to VCC−0.2 V) and appear in the Electrical Characteristics tables for all supply voltages.
Is LMV932ID suitable for automotive applications?
Yes, LMV932ID is characterized for operation from –40°C to +125°C and listed in TI's automotive-grade documentation for use in cabin modules, battery monitors, and sensor interfaces. It meets AEC-Q100 stress test requirements for temperature cycling and HTOL, and its 2-kV HBM ESD rating supports robustness in noisy vehicle environments.
