Product details
Overview
LMV932MM-TI from Texas Instruments is a dual, rail-to-rail input/output (RRIO) operational amplifier optimized for 1.8V operation. It delivers 1.4MHz gain bandwidth, 100μA per-channel supply current, and output swing within 105mV of rails at 1.8V with 600Ω load-enabling precision signal conditioning in ultra-low-voltage portable systems such as Li-ion battery-powered sensors and audio pre-amplifiers.
For engineers reviewing the LMV932MM-TI datasheet, LMV932MM-TI pinout, LMV932MM-TI application, or LMV932MM-TI equivalent, key selection criteria include guaranteed 1.8V/2.7V/5V operation, −40°C to 125°C temperature range, input common-mode voltage extending 200mV beyond supplies, high DC gain (101dB), and MSOP-8 packaging for space-constrained PCB layouts.
Technical Context
The LMV932MM-TI employs a complementary bipolar input stage with PNP and NPN transistors to achieve rail-to-rail input operation, where the PNP stage handles common-mode voltages near V− and the NPN stage covers near V+. This architecture enables input common-mode range from V− −0.2V to V+ +0.2V at 25°C, but introduces a VOS crossover point ~1V below V+, requiring careful signal placement to avoid distortion.
Its output stage drives 600Ω loads while maintaining rail-to-rail swing-within 105mV of rails at 1.8V-and supports up to 1000pF capacitive loads with minimal ringing. Phase margin is 67° at 1.8V, ensuring stable unity-gain buffer and closed-loop configurations without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - supports single-cell Li-ion (2.7–4.2V), two-cell alkaline (2.4–3.2V), and 3.3V/5V legacy systems without level-shifting. |
| Gain Bandwidth Product | 1.4MHz at 1.8V - enables stable AC-coupled audio preamp and sensor signal amplification up to ~100kHz with moderate gain. |
| Input Offset Voltage (Max) | 7.5mV - limits DC error in low-gain (<100×) instrumentation paths; requires trimming or calibration for sub-mV accuracy. |
| Supply Current per Channel | 205μA max at 25°C - allows dual-channel operation on <500μA total budget, suitable for always-on battery monitoring circuits. |
| Input Common-Mode Range | V− −0.2V to V+ +0.2V at 25°C - permits direct sensing of signals at ground or supply rail, e.g., high-side current sensing with no level shift. |
| Output Swing (600Ω load) | Within 105mV of rails at 1.8V - preserves dynamic range in low-voltage ADC interfaces and analog comparators. |
| CMRR / PSRR | ≥50dB over full common-mode range; ≥70dB PSRR - maintains accuracy in noisy mixed-signal environments with shared power rails. |
Pinout & Package
LMV932MM-TI is housed in an 8-pin MSOP package (NS drawing MUA08A), measuring 3.0mm × 3.0mm × 1.0mm, with exposed thermal pad for enhanced power dissipation in compact layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | Accepts feedback network input; high-impedance node requiring guard ring in high-precision layouts. |
| 2 | Non-Inverting Input (Channel A) | Reference input for Channel A; common-mode range extends beyond rails, enabling ground-referenced sensing. |
| 3 | Output (Channel A) | Rail-to-rail capable output; drives 600Ω directly; limited sourcing/sinking current (~8mA typical at 1.8V). |
| 4 | Ground (V−) | Negative supply terminal; must be low-impedance connection to minimize noise coupling into input stage. |
| 5 | Output (Channel B) | Independent rail-to-rail output for second channel; electrically isolated from Channel A except via shared supply pins. |
| 6 | Non-Inverting Input (Channel B) | Reference input for Channel B; identical electrical behavior to Pin 2, supporting dual independent signal paths. |
| 7 | Inverting Input (Channel B) | Feedback node for Channel B; matches Pin 1 in bias current (15–50nA) and offset characteristics. |
| 8 | Positive Supply (V+) | Power input for both channels; decoupling capacitor (0.1μF ceramic) required within 5mm for stability at 1.8V. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables direct interfacing with 0V–1.8V ADC references and ground-referenced sensors without external level shifters. |
| 1.8V guaranteed operation | Eliminates need for voltage regulators in single-cell Li-ion systems, reducing BOM count and quiescent power loss. |
| Ultra-low supply current (100μA/ch) | Supports dual-channel always-on functions like battery voltage/current monitoring in IoT endpoints with multi-year battery life. |
| High DC open-loop gain (101dB) | Ensures <0.01% gain error in unity-gain buffers and <0.1% error in 10× inverting amplifiers at room temperature. |
| −40°C to 125°C operating range | Validates use in automotive cabin modules, industrial sensor nodes, and outdoor portable equipment without derating. |

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-E/SN (Microchip) | Higher supply current (120μA/ch), lower GBW (1MHz at 2.7V), wider VOS range (max 5mV), SOIC-8 only. | Limited to 2.7V+ operation; less suitable for 1.8V-only systems; better VOS spec for precision DC apps. | Select when tighter input offset (≤5mV) is critical and 1.8V operation is not required. |
| TSV912IDT (STMicroelectronics) | Lower supply current (80μA/ch), higher GBW (8MHz at 5V), but only guaranteed down to 2.7V; no 1.8V characterization. | Not validated for 1.8V use; unsuitable for Li-ion discharge below 2.7V; superior speed for higher-V systems. | Choose for 3.3V/5V designs needing faster response; avoid in true 1.8V battery-powered applications. |
Compared with MCP6022-E/SN and TSV912IDT, LMV932MM-TI uniquely guarantees full performance at 1.8V with rail-to-rail I/O, making it the only option among the three qualified for deep-discharge Li-ion monitoring and ultra-low-power portable electronics where supply voltage drops below 2.0V.

FAQ
What is the minimum supply voltage for guaranteed operation of LMV932MM-TI?
The LMV932MM-TI is fully specified and guaranteed for operation from 1.8V to 5.5V. At 1.8V, it maintains 1.4MHz gain bandwidth, rail-to-rail input/output swing, and 100μA per-channel supply current. Operation below 1.8V is not characterized and may result in degraded CMRR, reduced output drive, or failure to meet input common-mode range specifications.
Does LMV932MM-TI support rail-to-rail input common-mode voltage beyond the supply rails?
Yes. The LMV932MM-TI input common-mode voltage range extends to V− −0.2V and V+ +0.2V at 25°C, enabling direct connection to signals at ground or above V+-critical for high-side current sensing and level translation without external components. This specification degrades slightly at temperature extremes (e.g., V− to V+ at 125°C).
Can LMV932MM-TI drive a 600Ω load while maintaining rail-to-rail output swing at 1.8V?
Yes. At 1.8V supply and 600Ω load, the LMV932MM-TI output swings within 105mV of each rail (i.e., 0.105V to 1.695V). This is explicitly tested and guaranteed in the datasheet. Performance assumes proper PCB layout: short traces, local 0.1μF decoupling, and avoidance of capacitive loads >1000pF without isolation resistance.
What is the maximum junction temperature and thermal resistance for LMV932MM-TI in MSOP-8 package?
The absolute maximum junction temperature for LMV932MM-TI is 150°C. Its thermal resistance θJA in the MSOP-8 package is 235°C/W under standard JEDEC test conditions. To stay within safe operating limits, power dissipation must be limited-for example, at 205μA per channel and 1.8V supply, total quiescent power is ~0.74mW, resulting in negligible self-heating under normal conditions.
Is LMV932MM-TI suitable for driving ADC inputs in 1.8V systems?
Yes. The LMV932MM-TI's rail-to-rail output swing, low output impedance, and 1.4MHz GBW make it well-suited for driving SAR and delta-sigma ADCs in 1.8V systems. Its output settles within 1μs to 0.1% of final value for a 1.8V step, supporting sampling rates up to ~100kSPS when paired with appropriate anti-aliasing filtering and PCB layout.
