Product details
Overview
LMV932IDR 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 LMV932IDR datasheet, LMV932IDR pinout, LMV932IDR application, or LMV932IDR equivalent, key selection criteria include its –40°C to 125°C operating range, SOIC-8 package compatibility with legacy layouts, rail-to-rail common-mode input extending 200 mV beyond supplies, and low-voltage performance validated at 1.8 V, 2.7 V, and 5 V.
Technical Context
The LMV932IDR employs complementary input stages enabling rail-to-rail input common-mode voltage (VICR = VCC– – 0.2 V to VCC+ + 0.2 V) and Class AB output stage supporting rail-to-rail output swing with 600 Ω load. Its 1.4 MHz gain bandwidth and 0.35 V/μs slew rate are specified across 1.8–5 V supply range.
Designed for low-power analog signal chains, it achieves 101 dB open-loop DC gain and >75 dB CMRR over full temperature range, with input offset voltage ≤5.5 mV (max) and average tempco ≤5.5 μV/°C - making it suitable for high-accuracy sensor amplification without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - supports direct connection to single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.4–3.2 V), or regulated 1.8/2.7/3.3/5 V rails. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to ~140 kHz with adequate phase margin. |
| Supply Current per Channel | 100 μA - allows dual-channel operation at <200 μA total, critical for always-on sensor nodes and energy-harvesting systems. |
| Input Offset Voltage (max) | 5.5 mV - ensures ≤0.55% error at 1 V output; sufficient for 10-bit ADC interfacing without calibration. |
| Rail-to-Rail Output Swing | 80 mV from rail into 600 Ω - preserves dynamic range in low-voltage systems where headroom is constrained. |
| Input Common-Mode Range | VCC– – 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above VCC, simplifying level-shifting in mixed-supply designs. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, utility metering, and industrial control environments. |
Pinout & Package
LMV932IDR is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch and 3.91 mm × 4.90 mm body dimensions, compatible with automated assembly and IPC-7351B footprint IPC-7351B SOIC-8_D.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives loads up to 600 Ω while maintaining rail-to-rail swing and minimal distortion. |
| 2 | IN− A | Inverting input - high-impedance node (IIB ≤75 nA) for feedback network connection in standard op-amp configurations. |
| 3 | IN+ A | Non-inverting input - accepts signals from VCC– – 0.2 V to VCC+ + 0.2 V, enabling true single-supply sensor interfacing. |
| 4 | VCC− | Negative supply rail - tied to ground in single-supply operation; must be decoupled with 0.1 μF ceramic capacitor. |
| 5 | IN+ B | Non-inverting input of second amplifier - electrically isolated from Channel A; supports dual independent signal paths. |
| 6 | IN− B | Inverting input of second amplifier - shares no internal coupling with Channel A; amplifier-to-amplifier isolation ≥123 dB. |
| 7 | OUT B | Second amplifier output - identical AC/DC specs to OUT A; enables stereo audio preamp or differential pair implementation. |
| 8 | VCC+ | Positive supply rail - accepts 1.8–5 V; quiescent current scales linearly with supply voltage (103 μA @ 1.8 V, 210 μA @ 2.7 V). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of supply voltage in single-supply systems - eliminates need for level-shifting circuitry in 1.8-V sensor interfaces. |
| 1.4-MHz gain bandwidth at 1.8 V | Maintains usable bandwidth down to lowest operating voltage - supports anti-alias filtering and active filtering in ultra-low-power data acquisition. |
| 100-μA per channel supply current | Reduces system-level power budget by >50% vs. comparable 2.7-V op-amps - extends battery life in portable medical monitors and IoT endpoints. |
| 200-mV beyond-rail input common-mode range | Accepts transducer outputs that swing slightly below ground or above VCC - removes requirement for external bias resistors in piezoelectric or thermocouple amplifiers. |
| Specified from –40°C to 125°C | Validated for use in automotive cabin modules, smart grid meters, and industrial PLC I/O without derating or thermal management. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9002IDR | Higher GBW (1 MHz vs. 1.4 MHz), lower VIO (1.6 mV typ), same SOIC-8 package and 1.8–5.5 V supply range. | Superior DC accuracy and faster settling for precision ADC drivers; higher supply current (125 μA/ch) reduces battery life. | Select TLV9002IDR when offset-critical applications demand <2-mV VIO and 1-MHz bandwidth suffices. |
| LMV358IDR | Lower GBW (1 MHz), higher supply current (150 μA/ch), rail-to-rail output only (not input), wider temp range (–40°C to 125°C same). | Cost-optimized alternative for non-critical signal paths where input rail-to-rail capability is unnecessary. | Choose LMV358IDR for cost-sensitive industrial controls where VICR limitation (0 to VCC–0.1 V) is acceptable. |
Compared with TLV9002IDR and LMV358IDR, LMV932IDR offers the best balance of ultra-low supply current (100 μA/ch), rail-to-rail input capability, and 1.4-MHz bandwidth - making it optimal for battery-constrained systems requiring wide input voltage tolerance.

FAQ
What is the maximum supply voltage rating for LMV932IDR?
The absolute maximum supply voltage (VCC+ – VCC–) for LMV932IDR is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 1.8 V to 5 V, with full electrical specifications guaranteed across this span - including 1.4 MHz gain bandwidth and rail-to-rail output swing at 1.8 V, 2.7 V, and 5 V.
Does LMV932IDR support true rail-to-rail input operation?
Yes, LMV932IDR supports true rail-to-rail input: its input common-mode voltage range extends from VCC– – 0.2 V to VCC+ + 0.2 V, verified across –40°C to 125°C. This allows direct interface with sensors whose outputs swing slightly below ground or above VCC - eliminating external bias networks required by conventional op-amps.
What is the typical output drive capability of LMV932IDR into 600 Ω?
At 1.8 V supply, LMV932IDR delivers rail-to-rail output swing within 80 mV of each rail into a 600 Ω load. At 2.7 V, low-level swing improves to 110 mV, and at 5 V it reaches 160 mV - all while maintaining THD <0.023% at 1 kHz. Sourcing/sinking short-circuit current is 30 mA (typ) at 2.7 V.
Is LMV932IDR suitable for automotive applications?
Yes, LMV932IDR is qualified for operation from –40°C to 125°C and specified across this full range for parameters including input offset voltage, CMRR, and gain bandwidth. It appears in TI's automotive-grade documentation for cabin temperature sensing, battery monitoring, and body control modules - meeting AEC-Q100 stress test requirements.
What package type and pin count does LMV932IDR use?
LMV932IDR uses an 8-pin SOIC (D) package with 1.27 mm lead pitch and JEDEC MS-012AC outline. Pinout matches industry-standard dual op-amp configuration: Pins 1/7 = outputs, Pins 2/6 = inverting inputs, Pins 3/5 = non-inverting inputs, Pin 4 = VCC−, Pin 8 = VCC+.
