Product details
Overview
LMV932MAX-TI from Texas Instruments is a dual, rail-to-rail input/output (RRIO) operational amplifier optimized for 1.8V operation, delivering 1.4MHz gain-bandwidth product, 100μA per-channel supply current, and output swing within 105mV of the rail under 600Ω load at 1.8V. It serves as a precision signal-conditioning front-end in low-voltage portable systems such as battery monitors and audio pre-amplifiers.
For engineers reviewing the LMV932MAX-TI datasheet, LMV932MAX-TI pinout, LMV932MAX-TI application, or LMV932MAX-TI equivalent, key selection criteria include guaranteed 1.8V/2.7V/5V operation, −40°C to 125°C temperature range, ultra-low power consumption, rail-to-rail common-mode input extending 200mV beyond supplies, and compatibility with space-constrained PCB layouts using SOIC-8 packaging.
Technical Context
The LMV932MAX-TI employs a complementary bipolar PNP/NPN input stage enabling rail-to-rail input common-mode voltage range (VCM = V− − 0.2V to V+ + 0.2V at 25°C), with a known VOS crossover point ~1V below V+. Its unity-gain-stable output stage drives 600Ω loads with minimal ringing and supports up to 1000pF capacitive loads.
It achieves 101dB open-loop DC gain, 77–101dB large-signal voltage gain (depending on load and supply), and 0.35V/μs slew rate at 1.8V - balancing speed, precision, and ultra-low quiescent current for single-cell Li-ion and two-cell alkaline applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8V to 5.5V - enables direct use with single-cell Li-ion (2.7–4.2V) or two-cell alkaline (2.4–3.2V) without regulation. |
| Gain-Bandwidth Product | 1.4MHz at 1.8V - supports stable closed-loop amplification up to ~100kHz with moderate gain (e.g., G = 10). |
| Input Offset Voltage (Max) | 7.5mV (dual version, −40°C to 125°C) - sets worst-case DC error floor in precision sensor interfaces. |
| Supply Current per Channel | 205μA max at 1.8V - allows >10-year battery life in always-on monitoring circuits drawing <500nA average with duty cycling. |
| Output Swing (600Ω load) | Within 105mV of rails at 1.8V - preserves dynamic range in low-voltage ADC drivers and comparator reference buffers. |
| Input Common-Mode Range | V− − 0.2V to V+ + 0.2V (25°C) - enables high-side current sensing and ground-referenced signal acquisition without level-shifting. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin, industrial control, and extended-environment portable equipment. |
Pinout & Package
LMV932MAX-TI is packaged in an 8-pin SOIC (Small Outline Integrated Circuit) with standard industry footprint (M08A), 1.27mm pitch, and 4.9mm × 3.9mm body size - compatible with automated SMT assembly and legacy board layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node accepting differential feedback; bias current ≤50nA enables high-Z sensor interfacing. |
| 2 | Non-Inverting Input (Channel A) | Accepts rail-to-rail common-mode signals; VCM extends 200mV beyond supplies for enhanced flexibility. |
| 3 | Output (Channel A) | Rail-to-rail capable; delivers ≥3.3mA sourcing/sinking into 600Ω at 1.8V while maintaining linearity. |
| 4 | V− (Ground/Ref) | Power return for single-supply operation; must be low-impedance to minimize PSRR degradation. |
| 5 | Non-Inverting Input (Channel B) | Independent input for second channel; identical specs to Pin 2 - supports dual-path signal conditioning. |
| 6 | Inverting Input (Channel B) | Matches Pin 1 electrical behavior; enables matched dual configurations like instrumentation amp front-ends. |
| 7 | Output (Channel B) | Electrically isolated from Channel A; 123dB amp-to-amp isolation prevents crosstalk in multi-channel filters. |
| 8 | V+ | Positive supply rail; accepts 1.8–5.5V; PSRR ≥70dB ensures immunity to supply ripple in noisy environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual RRIO operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-E/SN (Microchip) | Higher supply current (120μA/ch typ), wider GBW (10MHz), but only specified down to 2.7V - not guaranteed at 1.8V. | Preferred for higher-speed filtering or active anti-aliasing; unsuitable for sub-2.7V battery cutoff scenarios. | Select when speed >1MHz and supply ≥2.7V; avoid where 1.8V brownout operation is required. |
| TSV912IDT (STMicroelectronics) | Lower input offset (1.5mV max), lower noise (24nV/√Hz), but higher quiescent current (160μA/ch typ) and narrower temp range (−40°C to 125°C same). | Better for precision DC-coupled sensor bridges; less optimal for ultra-low-power long-life battery systems. | Choose for improved DC accuracy and noise where power budget allows ≥60% higher current draw. |
Compared with MCP6022-E/SN and TSV912IDT, LMV932MAX-TI uniquely guarantees full parametric performance at 1.8V while maintaining the lowest supply current among comparably specified dual RRIO op-amps - making it the only viable option for true single-cell Li-ion or two-cell alkaline systems requiring both rail-to-rail operation and microamp-level quiescent power.

FAQ
What is the minimum supply voltage guaranteed for full specification compliance of the LMV932MAX-TI?
The LMV932MAX-TI is fully specified and guaranteed to meet all electrical parameters at 1.8V supply voltage, including input common-mode range, output swing, gain-bandwidth product, and supply current. This 1.8V guarantee - confirmed across −40°C to +125°C - makes LMV932MAX-TI uniquely suitable for direct connection to single-cell Li-ion batteries and two-cell alkaline systems without voltage regulation.
Does the LMV932MAX-TI support rail-to-rail input common-mode voltage, and how far beyond the rails does it extend?
Yes, the LMV932MAX-TI supports rail-to-rail input common-mode voltage, with VCM extending 200mV beyond both supply rails (V− − 0.2V to V+ + 0.2V) at 25°C. This feature enables high-side current sensing and ground-referenced signal acquisition in single-supply configurations - a capability explicitly validated in the LMV932MAX-TI datasheet for applications like battery chargers and supply monitors.
What is the maximum output current capability of the LMV932MAX-TI at 1.8V supply?
At 1.8V supply, the LMV932MAX-TI delivers a minimum sourcing current of 3.3mA and sinking current of 5mA into short-circuit conditions (VO = 0V or VO = 1.8V). Under 600Ω load, it sustains rail-to-rail output swing with ≤105mV headroom - confirming usable linear output current ≥2.5mA per channel at 1.8V, sufficient for driving ADC inputs, analog switches, and small LEDs without external buffers.
Is the LMV932MAX-TI pin-compatible with other dual op-amps in SOIC-8 package?
No, LMV932MAX-TI uses the industry-standard SOIC-8 pinout for dual op-amps (pins 1–3/5–7 as Ch A/B inputs/outputs, pins 4/V− and 8/V+), matching generic dual op-amp conventions. However, functional compatibility depends on electrical specs - e.g., while pinout matches TLV2372 or MCP6022, LMV932MAX-TI's 1.8V guarantee and 100μA/ch current are unique. Always verify supply range, gain-bandwidth, and offset before substitution.
What is the typical input voltage noise density of the LMV932MAX-TI at 10kHz?
The LMV932MAX-TI exhibits a typical input-referred voltage noise density of 60nV/√Hz at 10kHz (1.8V supply, VCM = 0.5V), as measured and documented in the official datasheet. This value remains consistent across 2.7V and 5V supplies (57nV/√Hz and 50nV/√Hz respectively), supporting low-noise audio and sensor signal chains where broadband noise impacts SNR.
