Product details
Overview
LMV932MM from Texas Instruments is a dual, rail-to-rail input/output (RRIO) operational amplifier optimized for 1.8-V operation, delivering 1.4-MHz gain bandwidth, 100-μA per-channel supply current, and output swing within 30 mV of rails under 2-kΩ load. It serves as a precision signal-conditioning front-end in ultra-low-power portable systems such as battery voltage monitors and wearable sensor interfaces.
For engineers reviewing the LMV932MM datasheet, LMV932MM pinout, LMV932MM application, or LMV932MM equivalent, key selection criteria include its 1.8-V minimum supply capability, −40°C to +125°C operating range, rail-to-rail common-mode input extending 200 mV beyond supplies, and VSSOP-8 packaging suited for space-constrained PCB layouts in mobile and health-monitoring devices.
Technical Context
The LMV932MM implements a CMOS input stage enabling rail-to-rail input common-mode range (VCM = V− − 0.2 V to V+ + 0.2 V at 25°C) and rail-to-rail output swing (e.g., 30 mV from rail with 2-kΩ load at 1.8 V). Its 1.4-MHz GBW and 0.35-V/μs slew rate support stable unity-gain buffering and low-frequency amplification in single-supply configurations.
Designed for low-noise, low-distortion performance, it achieves 60-dB CMRR over extended common-mode range, 75-dB PSRR, and 0.022% THD at 1 kHz with 600-Ω load. Input-referred voltage noise is 60 nV/√Hz at 10 kHz, and amplifier-to-amplifier isolation exceeds 123 dB-critical for dual-channel signal integrity in compact mixed-signal designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V - enables direct interface with single-cell Li-ion (3.0–3.6 V), two-cell alkaline (2.4–3.2 V), and 1.8-V logic domains without level shifting. |
| Gain Bandwidth Product | 1.4 MHz - supports stable closed-loop gain up to ~100× at 10 kHz for sensor signal amplification in portable health monitors. |
| Input Offset Voltage (max) | 5.5 mV at 25°C - ensures ≤550 μV error in 100× gain stages, suitable for millivolt-level biomedical transducer outputs. |
| Supply Current per Channel | 103–205 μA - allows continuous operation for >1 year on a 200-mAh coin cell in always-on wearable applications. |
| Output Swing (2-kΩ load) | Within 30 mV of each rail at 1.8 V - preserves dynamic range in single-supply ADC driver circuits without negative bias. |
| Input Common-Mode Range | V− − 0.2 V to V+ + 0.2 V - permits sensing below ground or above V+, e.g., high-side current sense with bidirectional shunt monitoring. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin modules and industrial edge sensors without derating. |
Pinout & Package
LMV932MM is packaged in an 8-pin VSSOP (DGK) with nominal body size 3.00 mm × 3.00 mm, optimized for thermal performance (RθJA = 184.5°C/W) and PCB area efficiency in handheld devices.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives low-impedance loads (≥600 Ω) with rail-to-rail swing; requires local 100-pF bypass if driving >1000-pF capacitive loads. |
| 2 | −IN A | Inverting input, channel A - forms feedback node in inverting configurations; high-impedance CMOS input minimizes bias current error (15–50 nA). |
| 3 | +IN A | Noninverting input, channel A - accepts signals from V− − 0.2 V to V+ + 0.2 V, enabling ground-referenced or beyond-rail sensor interfacing. |
| 4 | V− | Negative supply - tied to GND in single-supply use; must be decoupled with 0.1-μF ceramic capacitor near pin. |
| 5 | V+ | Positive supply - accepts 1.8–5.5 V; shared by both amplifiers; requires separate 0.1-μF + 1-μF parallel decoupling. |
| 6 | −IN B | Inverting input, channel B - electrically isolated from channel A (123 dB inter-channel isolation) for dual-path signal processing. |
| 7 | OUT B | Amplifier B output - independent output stage; supports simultaneous dual-sensor conditioning without crosstalk. |
| 8 | +IN B | Noninverting input, channel B - identical electrical specs to +IN A; enables matched differential pair or independent analog paths. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 1.8-V supply: input accepts signals down to −0.2 V and up to +2.0 V; output delivers 0.03–0.105 V headroom depending on load. |
| Ultra-low quiescent current | 103 μA per channel at 1.8 V - reduces system standby power by >50% versus comparable 2.7-V op-amps, extending battery life in IoT endpoints. |
| High DC open-loop gain | 75–101 dB - ensures <0.1% gain error in precision instrumentation amplifiers and 12-bit ADC driver applications. |
| Enhanced ESD robustness | ±2000-V HBM rating - eliminates need for external ESD protection in consumer wearables exposed to frequent human handling. |
| Stable with capacitive loads | Drives up to 1000-pF with minimal ringing - simplifies design of anti-aliasing filters and sensor excitation circuits without isolation resistors. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RRIO op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN | Higher supply current (125 μA/ch), wider GBW (10 MHz), but only specified down to 2.7 V - not 1.8 V compliant. | Unsuitable for true 1.8-V systems; requires ≥2.7 V supply, limiting compatibility with modern ultra-low-power MCUs. | Select when higher speed is critical and supply ≥2.7 V is guaranteed; avoid where 1.8-V brownout tolerance is required. |
| TSV912IDT | Lower input offset (1.5 mV typ), same 1.8-V min, but lower output drive (25 mA short-circuit vs LMV932MM's 30 mA at 2.7 V). | Better DC precision but reduced ability to drive heavy capacitive or resistive loads in noisy industrial settings. | Prefer for high-accuracy sensor calibration; choose LMV932MM when driving 600-Ω loads or >1000-pF filters is required. |
Compared with MCP6022-I/SN and TSV912IDT, the LMV932MM uniquely balances 1.8-V operability, 100-μA quiescent current, and 30-mV rail-to-rail output swing - making it the only option among the three qualified for battery-powered devices operating across full Li-ion voltage range (2.7–4.2 V) while maintaining sub-100-μA system sleep current.

FAQ
What is the minimum supply voltage specification for the LMV932MM?
The LMV932MM is fully specified and functional down to 1.8 V, with all key parameters-including gain bandwidth, input offset voltage, and output swing-guaranteed across the 1.8-V to 5.5-V range. This makes LMV932MM suitable for direct integration with 1.8-V I/O domains and single-cell Li-ion batteries without voltage regulation overhead.
Does the LMV932MM support rail-to-rail input common-mode voltage?
Yes, the LMV932MM supports rail-to-rail input common-mode voltage, extending 200 mV beyond both supply rails (V− − 0.2 V to V+ + 0.2 V at 25°C). This capability allows LMV932MM to accurately condition signals referenced below ground or above V+, such as in high-side current sensing or bipolar sensor interfaces.
What package type is used for the LMV932MM, and what are its thermal characteristics?
The LMV932MM is supplied in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm. Its thermal resistance is RθJA = 184.5°C/W, RθJC(top) = 74.3°C/W, and RθJB = 105.1°C/W-enabling reliable operation in compact, unventilated enclosures typical of wearables and handheld instruments.
Can the LMV932MM drive capacitive loads, and what is the maximum stable value?
The LMV932MM is characterized to drive up to 1000-pF capacitive loads with minimal ringing and no external compensation. This stability allows direct connection to anti-aliasing filters, long PCB traces, or ADC input capacitance without series isolation resistors-simplifying layout and preserving signal fidelity in LMV932MM-based data acquisition circuits.
How does the LMV932MM perform in terms of power supply rejection at 1.8 V?
At 1.8 V, the LMV932MM delivers 75 dB minimum PSRR (typical 100 dB) across DC to low frequencies, effectively suppressing ripple and noise from switching regulators or noisy digital supplies. This PSRR performance remains consistent across temperature (−40°C to +125°C), ensuring robust operation in LMV932MM-based battery-powered systems exposed to varying environmental conditions.
