Product details
Overview
LMV932IDE4 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 - used in battery-powered industrial metering and portable audio signal conditioning.
For engineers reviewing the LMV932IDE4 datasheet, LMV932IDE4 pinout, LMV932IDE4 application, or LMV932IDE4 equivalent, key selection criteria include rail-to-rail I/O capability at 1.8 V, −40°C to 125°C operating range, SOIC-8 package compatibility, and low-input-offset-voltage performance in space-constrained low-power sensor interfaces.
Technical Context
The LMV932IDE4 implements a CMOS input stage with Class AB output stage, enabling rail-to-rail input common-mode voltage range extending 200 mV beyond supplies and rail-to-rail output swing under load. Its architecture supports stable operation with capacitive loads up to 1000 pF while maintaining ≥67° phase margin.
It features matched dual amplifiers sharing a common die, with amplifier-to-amplifier isolation of 123 dB (input-referred, 1 kHz), and operates across full 1.8–5 V supply range without re-biasing - making it suitable for mixed-voltage signal chains where supply headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - enables direct interface with Li-ion single-cell or two-cell alkaline systems without level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - supports unity-gain stable buffering and filtering up to ~100 kHz with adequate phase margin. |
| Input Offset Voltage (max) | 7.5 mV - ensures ≤7.5 mV DC error in precision DC-coupled gain stages at full temperature range. |
| Supply Current per Channel | 205 μA (max, full temp) - allows dual-channel amplification in always-on sub-100-μA system power budgets. |
| Output Swing (600 Ω load) | Within 80 mV of rails at 1.8 V - preserves >95% dynamic range in low-voltage ADC driver applications. |
| Input Common-Mode Range | VCC− − 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above VCC, simplifying level translation. |
| Operating Temperature | −40°C to +125°C - qualified for automotive cabin and industrial utility meter environments. |
Pinout & Package
LMV932IDE4 is housed in an 8-pin SOIC (D) package with standard 1.27-mm pitch, 3.91-mm width, and 4.90-mm length - compatible with automated PCB assembly and legacy socket footprints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail buffered or amplified signal; drives 600 Ω loads with <80 mV headroom at 1.8 V. |
| 2 | Channel 1 Inverting Input | Accepts feedback network connection; supports active filter and transimpedance configurations. |
| 3 | Channel 1 Non-Inverting Input | Receives high-impedance sensor or reference signals; input bias current ≤75 nA minimizes offset error. |
| 4 | VCC− (Ground) | Power return node for both amplifiers; requires low-impedance local decoupling to maintain PSRR >70 dB. |
| 5 | VCC+ (Supply) | Positive supply input; accepts 1.8–5 V; internal regulation enables stable operation across voltage range. |
| 6 | Channel 2 Non-Inverting Input | Independent high-Z input for second signal path; matched offset and bias specs enable dual-sensor correlation. |
| 7 | Channel 2 Inverting Input | Feedback node for second amplifier; supports differential pair configuration with matched gain accuracy. |
| 8 | Channel 2 Output | Second independent output; identical AC/DC specs to Pin 1 - enables stereo audio or dual-channel monitoring. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal utilization in 1.8-V systems - eliminates need for external level shifters in sensor front-ends. |
| 200-mV beyond-rail input common-mode range | Supports input signals 200 mV below ground or above VCC - critical for interfacing with bipolar sensors or DACs. |
| 100-μA/channel quiescent current | Permits continuous operation in battery-powered devices with multi-year shelf life (e.g., smart meters). |
| 123-dB amplifier-to-amplifier isolation | Minimizes crosstalk between channels in dual-signal acquisition - essential for simultaneous voltage/current sensing. |
| Stable with 1000-pF capacitive load | Allows direct driving of ADC input capacitance or long traces without external isolation resistor. |

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 |
|---|---|---|---|
| TLV9002IDR | Lower 0.65-mV max VIO, 1-MHz GBW, 60-μA/channel ICC - optimized for higher-precision, lower-power use cases. | Preferred in battery-critical wearables where 40-μA savings per channel extends runtime significantly. | Select TLV9002IDR when VIO < 1 mV and ICC < 70 μA are mandatory; verify layout stability with lower GBW. |
| LMV358IDR | Higher 7-mV max VIO, 1-MHz GBW, 150-μA/channel ICC - older architecture with limited rail-to-rail input (VICR = 0 to VCC−0.1 V). | Suitable only where input signals stay within supply rails and 125°C rating is not required (rated −40°C to 85°C). | Choose LMV358IDR for cost-sensitive industrial controls where rail-to-rail input is unnecessary and extended temperature is not needed. |
Compared with TLV9002IDR and LMV358IDR, LMV932IDE4 uniquely balances 1.4-MHz bandwidth, rail-to-rail I/O, and 125°C operation - making it the only option among the three qualified for automotive-grade low-voltage sensor signal chains requiring full rail coverage and wide temperature support.

FAQ
What is the maximum supply voltage for LMV932IDE4?
The absolute maximum supply voltage (VCC+ − VCC−) for LMV932IDE4 is 5.5 V. However, the recommended operating range is 1.8 V to 5 V per channel. Operation above 5 V risks permanent damage and violates TI's specified conditions - design margins should maintain VCC ≤ 5 V for reliable long-term performance in all temperature conditions.
Does LMV932IDE4 support true rail-to-rail input?
Yes, LMV932IDE4 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 signals 200 mV below ground or above VCC to be accurately amplified - a key differentiator versus conventional op-amps with limited VICR.
What is the output drive capability of LMV932IDE4 into 600 Ω at 1.8 V?
At 1.8 V supply and 25°C, LMV932IDE4 delivers output swing within 80 mV of each rail into a 600 Ω load - i.e., low-level output ≥ 0.08 V and high-level output ≤ 1.72 V. This is confirmed in the Electrical Characteristics table (SLOS441G, page 4) and enables >95% utilization of 1.8-V ADC full-scale range.
Is LMV932IDE4 pin-compatible with other dual op-amps in SOIC-8?
LMV932IDE4 follows the industry-standard dual op-amp SOIC-8 pinout (Pin 1 = OUT A, Pin 2 = −IN A, Pin 3 = +IN A, Pin 4 = V−, Pin 5 = V+, Pin 6 = +IN B, Pin 7 = −IN B, Pin 8 = OUT B), matching LMV358, TLV2372, and MCP6022. However, functional compatibility requires verification of rail-to-rail I/O, supply range, and temperature rating - LMV932IDE4 is not a drop-in replacement for non-rail-to-rail parts.
Why is LMV932IDE4 marked 'Not Recommended for New Designs'?
TI designated LMV932IDE4 as 'Not Recommended for New Designs' (NRND) in 2006 due to newer alternatives like TLV9002 offering improved VIO, lower ICC, and enhanced ESD robustness. LMV932IDE4 remains fully qualified and supported for existing designs, with guaranteed supply through Aetrix Electronics' continuity programs - but new designs should evaluate TLV9002IDR or OPA320 series.
