Product details
Overview
LMV932IDRE4 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 sensor signal conditioning and portable audio front-ends.
For engineers reviewing the LMV932IDRE4 datasheet, LMV932IDRE4 pinout, LMV932IDRE4 application, or LMV932IDRE4 equivalent, this page provides verified package mapping (SOIC-8), confirmed rail-to-rail I/O behavior, temperature-stable offset voltage (≤7.5 mV over –40°C to 125°C), and direct alternative part comparisons for low-voltage analog design validation.
Technical Context
The LMV932IDRE4 integrates two independent amplifiers with Class AB output stages enabling rail-to-rail output swing under load, while its input common-mode range extends 200 mV beyond both supply rails. It operates across 1.8 V–5 V with guaranteed performance at –40°C to +125°C.
Each amplifier features 101 dB open-loop DC gain, 67° phase margin, and 7 dB gain margin at 1.8 V, supporting stable unity-gain configurations driving capacitive loads up to 1000 pF. Input bias current remains ≤75 nA across full temperature range.
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 battery systems without level-shifting. |
| Gain Bandwidth Product | 1.4 MHz - supports audio-band filtering and anti-aliasing up to ~100 kHz with ≥20 dB gain margin. |
| Input Offset Voltage | ≤7.5 mV (full temp range) - ensures ≤0.75% error in 1-V full-scale sensor outputs without trimming. |
| Supply Current per Channel | 100 μA typical at 1.8 V - allows >1-year operation on 200 mAh coin cell in always-on monitoring circuits. |
| Output Swing (600 Ω) | Within 80 mV of rails at 1.8 V - preserves >90% dynamic range in low-voltage ADC driver applications. |
| Common-Mode Input Range | VCC− − 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above VCC, simplifying bipolar signal interfacing. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive and industrial metering environments. |
Pinout & Package
LMV932IDRE4 is housed in an 8-pin SOIC (D) package with standard 1.27 mm pitch, 3.91 mm × 4.90 mm body size, and exposed pad not present. Pinout matches industry-standard dual op-amp configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Delivers rail-to-rail buffered signal; capable of sourcing 30 mA/sinking 45 mA at 1.8 V. |
| 2 | Channel 1 Inverting Input | Differential node for feedback networks; input bias current ≤75 nA minimizes resistor-induced offset. |
| 3 | Channel 1 Non-Inverting Input | High-impedance sensor interface point; common-mode range extends 200 mV beyond supplies. |
| 4 | VCC− (Ground) | Power return reference for both amplifiers; requires low-impedance local decoupling to minimize PSRR degradation. |
| 5 | Channel 2 Non-Inverting Input | Independent high-Z input for second signal path; matched offset and bias specs to Channel 1. |
| 6 | Channel 2 Inverting Input | Second differential feedback node; identical electrical characteristics to Pin 2. |
| 7 | Channel 2 Output | Second rail-to-rail output; amplifier-to-amplifier isolation >123 dB prevents crosstalk in dual-channel systems. |
| 8 | VCC+ | Positive supply rail; accepts 1.8–5 V; internal ESD protection rated to 2 kV HBM. |
Key Features
| Feature | Design Value |

| 200-mV beyond-rail input common-mode range | Supports direct connection to transducers with output offsets exceeding supply rails (e.g., bridge sensors). |
| 100-μA/channel quiescent current | Permits integration into ultra-low-power wake-on-event architectures with sub-1-μA system sleep current. |
| 1.4-MHz GBW at 1.8 V | Provides sufficient bandwidth for 10-bit SAR ADC drivers and active RC filters up to 100 kHz. |
| Specified from –40°C to +125°C | Eliminates derating calculations for industrial energy metering and automotive cabin control modules. |

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 VIO (1.6 mV typ), higher GBW (1 MHz), 65 μA/channel ICC - but only specified down to –40°C (not +125°C). | Limited to commercial/industrial ambient ranges; unsuitable for under-hood automotive or high-temp metering. | Choose TLV9002IDR for cost-sensitive consumer designs requiring tighter offset and lower power at <85°C ambient. |
| MCP6022-I/SN | Higher supply current (120 μA/ch), wider VCC range (2.7–6 V), no beyond-rail VICR - but AEC-Q100 qualified. | Supports automotive qualification requirements; lacks 1.8-V operation and rail-to-rail input capability. | Choose MCP6022-I/SN when AEC-Q100 compliance is mandatory and 2.7-V minimum supply is acceptable. |
Compared with TLV9002IDR and MCP6022-I/SN, LMV932IDRE4 uniquely combines 1.8-V operation, beyond-rail input range, and +125°C rating - making it irreplaceable in space-constrained, wide-temperature industrial sensing nodes where supply headroom and signal range are critical.

FAQ
What is the maximum operating temperature for LMV932IDRE4?
The LMV932IDRE4 is characterized for continuous operation from –40°C to +125°C. This full industrial temperature range is explicitly validated in the SLOS441G datasheet across all key parameters including input offset voltage, supply current, and output swing - making LMV932IDRE4 suitable for under-hood automotive and energy metering applications where ambient temperatures exceed 105°C.
Does LMV932IDRE4 support true rail-to-rail input operation?
Yes, LMV932IDRE4 supports rail-to-rail input with a common-mode voltage range extending 200 mV beyond both supply rails (VCC− − 0.2 V to VCC+ + 0.2 V). This is confirmed in the Electrical Characteristics tables for all supply voltages (1.8 V, 2.7 V, 5 V) and across the full –40°C to +125°C temperature range - enabling direct interface to sensors whose output exceeds the supply domain.
What is the typical supply current per channel for LMV932IDRE4 at 1.8 V?
At 1.8 V supply and 25°C, LMV932IDRE4 draws 103 μA per channel (typical), with a maximum of 205 μA over the full temperature range. This value is measured under standard conditions (VIC = VCC+/2, VO = VCC+/2) and is consistent across all LMV932 variants - confirming its suitability for multi-year battery life in always-on monitoring systems.
Is LMV932IDRE4 pin-compatible with other dual op-amps in SOIC-8 packages?
LMV932IDRE4 uses the industry-standard dual op-amp pinout (Pin 1 = OUT A, Pin 2 = IN− A, Pin 3 = IN+ A, Pin 4 = V−, Pin 5 = IN+ B, Pin 6 = IN− B, Pin 7 = OUT B, Pin 8 = V+), matching devices like LM358, TLV2372, and MCP6022. However, electrical compatibility requires verification of input stage architecture, rail-to-rail capability, and temperature specifications - LMV932IDRE4's beyond-rail VICR and 1.8-V operation are not shared by most legacy SOIC-8 dual op-amps.
Why is LMV932IDRE4 marked as "Not Recommended for New Designs"?
TI classifies LMV932IDRE4 as "Not Recommended for New Designs" due to newer alternatives (e.g., TLV9002) offering improved specs like lower offset and higher speed. However, LMV932IDRE4 remains in active obsolescence status (OBSOLETE per TI's 2016 Addendum), meaning it is discontinued but still supported for existing designs - with full datasheet validation, known reliability history, and proven performance in deployed industrial systems.
