Product details
Overview
LMV934IDE4 from Texas Instruments is a quad 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 amplifier supply current, and output swing within 80 mV of rails into 600 Ω - used in battery-powered industrial metering and automotive sensor signal conditioning.
For engineers reviewing the LMV934IDE4 datasheet, LMV934IDE4 pinout, LMV934IDE4 application, or LMV934IDE4 equivalent, key selection criteria include its rail-to-rail input common-mode range extending 200 mV beyond supplies, low 4 mV max input offset voltage, and SOIC-14 packaging compatible with legacy PCB layouts requiring quad op-amp functionality at ultra-low power.
Technical Context
The LMV934IDE4 integrates four independent amplifiers on a single die with Class AB output stage enabling rail-to-rail output swing under load. Its input stage uses complementary NPN/PNP transistors to achieve rail-to-rail common-mode input voltage range (VICR = VCC− − 0.2 V to VCC+ + 0.2 V) and 200 mV beyond rails CMVR specification.
Each amplifier features 101 dB open-loop DC gain, 1.4 MHz unity-gain bandwidth, and stable operation driving capacitive loads up to 1000 pF into 600 Ω without oscillation - validated across −40°C to +125°C operating temperature range with 1.8-V, 2.7-V, and 5-V supply support.
Key Specifications

|---|---|
| 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 and low-speed sensor signal amplification with stable unity-gain configuration. |
| Input Offset Voltage (max) | 4 mV - ensures ≤4 mV DC error in precision DC-coupled gain stages such as current-sense amplifiers. |
| Supply Current per Channel | 100 μA - allows four-channel operation at <400 μA total quiescent current for always-on portable monitoring nodes. |
| Output Swing (600 Ω load) | Within 80 mV of rails - preserves >95% dynamic range in 1.8-V systems where headroom is critical. |
| Common-Mode Input Range | VCC− − 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above VCC, simplifying single-supply transducer interfacing. |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load directly; rail-to-rail swing supports full-scale ADC input buffering. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance node for feedback network connection in inverting configurations. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - accepts signals from sensors or DACs with rail-to-rail common-mode capability. |
| 4 | VCC+ | Positive supply rail - connects to main system VDD (1.8–5 V); decoupling capacitor required near pin. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other channels; enables independent signal paths. |
| 6 | 2IN− | Inverting input of Amplifier B - referenced to local feedback network; no crosstalk with Amplifier A pins. |
| 7 | 2OUT | Amplifier B output - identical drive strength and swing to Pin 1; supports dual-channel simultaneous operation. |
| 8 | VCC− | Negative supply rail - typically GND in single-supply systems; serves as reference for all four amplifiers. |
| 9 | 3IN+ | Non-inverting input of Amplifier C - matches electrical characteristics of Pins 3 and 5; verified over full temperature range. |
| 10 | 3IN− | Inverting input of Amplifier C - shares same input bias current (65 nA typ) and offset specs as other channels. |
| 11 | 3OUT | Amplifier C output - delivers same 1.4-MHz GBW and 100-μA quiescent current as all channels. |
| 12 | 4IN− | Inverting input of Amplifier D - fully characterized for CMRR ≥50 dB across 0.2 V to VCC+ − 0.2 V input range. |
| 13 | 4IN+ | Non-inverting input of Amplifier D - supports VICR extension to VCC− − 0.2 V, enabling sub-ground signal handling. |
| 14 | 4OUT | Amplifier D output - maintains 80-mV rail margin into 600 Ω at 1.8 V, matching performance of Pins 1, 7, and 11. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV934IDR | Same SOIC-14 package, identical electrical specs, RoHS-compliant lead finish; LMV934IDE4 has legacy green molding compound. | No functional difference; both qualified for −40°C to +125°C operation and share full pinout compatibility. | Select LMV934IDR for new designs requiring active TI support and documented Pb-Free compliance. |
| MCP6004-E/SL | Microchip quad op-amp with 1 MHz GBW, 100 μA IQ, rail-to-rail I/O, but only specified down to −40°C (not +125°C). | Limited to commercial/industrial ambient ranges; unsuitable for under-hood automotive or high-temp energy metering. | Choose MCP6004-E/SL only when extended temperature qualification is unnecessary and cost sensitivity outweighs thermal margin. |
Compared with LMV934IDR and MCP6004-E/SL, LMV934IDE4 offers identical performance in SOIC-14 but is marked obsolete by TI; LMV934IDR provides drop-in replacement with updated eco-plan, while MCP6004-E/SL trades temperature range for broader distributor availability.

FAQ
What is the maximum supply voltage rating for LMV934IDE4?
The absolute maximum supply voltage (VCC+ – VCC−) for LMV934IDE4 is 5.5 V. Operation beyond this risks permanent damage. The recommended operating range is 1.8 V to 5 V, with full electrical specifications guaranteed across that span. At 5 V, LMV934IDE4 delivers 1.5 MHz gain bandwidth and output swing within 160 mV of rails into 600 Ω - consistent with its 1.8-V performance envelope.
Does LMV934IDE4 support true rail-to-rail input common-mode voltage range?
Yes, LMV934IDE4 supports a rail-to-rail input common-mode voltage range extending 200 mV beyond both supply rails (VICR = VCC− − 0.2 V to VCC+ + 0.2 V), verified across −40°C to +125°C. This allows direct interfacing with sensors whose outputs fall slightly below ground or exceed VCC - eliminating need for external bias networks in LMV934IDE4-based designs.
Is LMV934IDE4 pin-compatible with other packages in the LMV93x family?
No - LMV934IDE4 uses the SOIC-14 (D) package, while LMV934IPW uses TSSOP-14 (PW). Though both contain identical amplifier cores and share identical pin functions, their footprints are mechanically incompatible. LMV934IDE4 is not pin-compatible with LMV932 (SOIC-8) or LMV931 (SOT-23-5); each LMV93x variant has unique pin count and layout.
What is the typical input offset voltage drift over temperature for LMV934IDE4?
The average temperature coefficient of input offset voltage for LMV934IDE4 is 5.5 μV/°C, measured across 25°C. This drift rate applies to all LMV932 and LMV934 variants. Over the full −40°C to +125°C range, total VIO shift remains within ±1.0 mV for most units, supporting stable DC-coupled gain accuracy in LMV934IDE4 applications like precision current sensing.
Can LMV934IDE4 drive capacitive loads without instability?
Yes, LMV934IDE4 is characterized to drive up to 1000 pF capacitive loads in parallel with a 600 Ω resistor while maintaining ≥67° phase margin and minimal ringing - confirmed in TI's SLOS441G datasheet Figure 10–13. For loads exceeding 1000 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability in LMV934IDE4 circuits.
