Product details
Overview
LMV932IDG4 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 under 600-Ω load - used in battery-powered industrial metering and automotive sensor signal conditioning.
For engineers reviewing the LMV932IDG4 datasheet, LMV932IDG4 pinout, LMV932IDG4 application, or LMV932IDG4 equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail I/O behavior, thermal performance at –40°C to 125°C, and two validated alternative parts with documented functional trade-offs.
Technical Context
The LMV932IDG4 integrates two independent amplifiers in a single SOIC-8 package, each featuring Class AB output stage and input common-mode range extending 200 mV beyond supply rails. Its internal biasing enables stable operation down to 1.8 V while maintaining ≥73 dB large-signal voltage gain into 600 Ω.
Designed for low-voltage portable systems, it supports direct interfacing with ADCs and microcontroller analog inputs without level-shifting. The device exhibits 60 nV/√Hz input voltage noise at 1 kHz and maintains ≥67° phase margin with 150 pF capacitive load at 1.8 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - supports single-cell Li-ion and two-cell alkaline/battery systems without regulation. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer and low-frequency filtering up to ~100 kHz. |
| Input Offset Voltage (max) | 7.5 mV - ensures ≤±15 mV error in 2.5 V full-scale 12-bit ADC front-end at room temperature. |
| Rail-to-Rail Output Swing | 80 mV from rail into 600 Ω - preserves dynamic range in low-voltage data acquisition with minimal headroom loss. |
| Supply Current per Channel | 100 μA - allows continuous monitoring in always-on battery nodes with <1 mAh/year quiescent drain. |
| Common-Mode Input Range | VCC− − 0.2 V to VCC+ + 0.2 V - accepts signals below ground or above supply, simplifying sensor interface design. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial energy metering environments. |
Pinout & Package
LMV932IDG4 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 up to 85°C ambient without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 600 Ω with rail-to-rail swing and 30 mV settling error. |
| 2 | IN− A | Inverting input of Amplifier A - high-impedance node (IIB = 65 nA max) for precision feedback networks. |
| 3 | IN+ A | Non-inverting input of Amplifier A - accepts common-mode voltages beyond rails for sensor offset handling. |
| 4 | VCC− | Negative supply rail - connects to system ground in single-supply configurations; must be decoupled with 0.1 μF ceramic. |
| 5 | IN+ B | Non-inverting input of Amplifier B - electrically isolated from Amplifier A; supports dual-channel signal conditioning. |
| 6 | IN− B | Inverting input of Amplifier B - matched bias current enables common-mode rejection in differential configurations. |
| 7 | OUT B | Amplifier B output - identical AC/DC specs to Pin 1; supports independent gain stages or parallel drive. |
| 8 | VCC+ | Positive supply rail - operates from 1.8 V to 5 V; requires local 0.1 μF + 2.2 μF decoupling for stability. |
Key Features

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/ch), wider GBW (6.4 MHz), lower VIO (2 mV max) | Better for higher-speed sensor interfaces but increases battery load 5.5× | Select when speed >1 MHz and precision <2 mV required; avoid in ultra-low-power designs. |
| LPV521MG/NOPB | Lower supply current (320 nA/ch), lower GBW (155 kHz), rail-to-rail I/O | Optimized for nanowatt sensing, not suitable for audio or fast response | Select for multi-year battery life in wake-on-event systems; insufficient bandwidth for metering sampling rates >1 kSPS. |
Compared with TLV2462IDR and LPV521MG/NOPB, LMV932IDG4 uniquely balances 1.4 MHz bandwidth, 100 μA power, and rail-to-rail operation - making it optimal for cost-sensitive industrial metering where moderate speed and ultra-low quiescent current are both required.

FAQ
What is the maximum supply voltage for LMV932IDG4?
The absolute maximum supply voltage (VCC+ – VCC−) for LMV932IDG4 is 5.5 V. However, the recommended operating range is 1.8 V to 5 V per the datasheet's Recommended Operating Conditions table. Operation above 5 V risks permanent damage and violates TI's specified reliability testing boundaries; sustained use at 5.5 V is not supported for long-term deployment.
Does LMV932IDG4 support true rail-to-rail input with signals below ground?
Yes, LMV932IDG4 supports a common-mode input voltage range from VCC− − 0.2 V to VCC+ + 0.2 V. When VCC− is connected to ground, this allows inputs as low as –0.2 V - enabling direct interface with transducers that produce slightly negative outputs, such as cold-junction-compensated thermocouples, without external level-shifting circuitry.
What is the typical output swing of LMV932IDG4 into a 600-Ω load at 1.8 V supply?
At 1.8 V supply and 25°C, LMV932IDG4 delivers a typical output swing of 0.08 V to 1.72 V into a 600-Ω load - i.e., within 80 mV of both rails. This is confirmed in the Electrical Characteristics table under "Output swing" with test condition RL = 600 Ω, VID = ±100 mV, and VO measured from rail.
Is LMV932IDG4 pin-compatible with other dual op-amps in SOIC-8 packages?
No, LMV932IDG4 is not guaranteed pin-compatible with generic SOIC-8 dual op-amps. Its pinout (OUT A, IN− A, IN+ A, VCC−, IN+ B, IN− B, OUT B, VCC+) follows TI's LMV93x family layout and differs from industry-standard configurations like the NE5532 or TL072. PCB redesign is required when substituting non-LMV93x devices.
What is the thermal resistance θJA of LMV932IDG4 in its SOIC-8 package?
The junction-to-ambient thermal resistance (θJA) for LMV932IDG4 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 conditions (1 inch² copper pad, 2 oz Cu); actual thermal performance may improve with enhanced PCB copper area or thermal vias.
