Product details
Overview
LMV934ID 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 LMV934ID datasheet, LMV934ID pinout, LMV934ID application, or LMV934ID equivalent, this page provides verified package mapping (SOIC-14), confirmed rail-to-rail I/O behavior, thermal performance at –40°C to 125°C, and validated alternatives for low-voltage analog front-end design.
Technical Context
The LMV934ID employs complementary input stage architecture enabling rail-to-rail common-mode input voltage range extending 200 mV beyond supply rails, with Class AB output stage supporting 600 Ω load drive and 1000 pF capacitive load stability. Its internal bias network maintains consistent quiescent current across 1.8–5 V supply range.
Each of the four independent amplifiers features matched DC specifications - including max 7.5 mV input offset voltage and 5.5 μV/°C drift - and shares identical small-signal response (1.4 MHz GBW, 0.35–0.42 V/μs slew rate) across supply voltages, enabling predictable multi-channel signal processing without channel-to-channel interaction.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - supports direct connection to single Li-ion or two-cell alkaline batteries without regulation. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer or gain-of-10 amplification up to 140 kHz with phase margin ≥67°. |
| Input Offset Voltage (max) | 7.5 mV - ensures ≤75 mV error at gain-of-10, suitable for precision DC-coupled sensor interfaces. |
| Supply Current per Channel | 100 μA - allows four-channel operation at <400 μA total, critical for always-on battery monitoring circuits. |
| Rail-to-Rail Output Swing | 80 mV from rail into 600 Ω - preserves >95% dynamic range in 1.8-V systems, minimizing headroom loss. |
| Input Common-Mode Range | VCC− −0.2 V to VCC+ +0.2 V - accepts signals below ground or above VCC, simplifying level-shifting in mixed-supply systems. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive and industrial energy metering environments. |
Pinout & Package
LMV934ID is packaged in 14-pin SOIC (D package), 8.65 mm × 3.91 mm body, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Thermal resistance θJA = 86°C/W enables operation at full ambient range without forced airflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load directly; rail-to-rail swing supports low-headroom ADC interfacing. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance node; requires matched trace routing to minimize CMRR degradation. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - accepts signals down to VCC− −0.2 V, enabling true single-supply transducer biasing. |
| 4 | VCC+ | Positive supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor to maintain PSRR >70 dB. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other inputs; enables independent channel configuration. |
| 6 | 2IN− | Inverting input of Amplifier B - shares no internal nodes with Amplifier A; supports dual feedback networks. |
| 7 | 2OUT | Amplifier B output - fully independent; can sink/source up to 30 mA short-circuit current at 2.7 V. |
| 8 | VCC− | Negative supply rail (ground reference) - return path for all four amplifiers; requires low-impedance PCB plane. |
| 9 | 3IN+ | Non-inverting input of Amplifier C - identical electrical characteristics to Pins 3 and 5; enables three-channel parallel sensing. |
| 10 | 3IN− | Inverting input of Amplifier C - matches input bias current (65 nA typ) across all channels for balanced differential designs. |
| 11 | 3OUT | Amplifier C output - delivers same AC performance (GBW, slew rate) as Pins 1 and 7; supports cascaded gain stages. |
| 12 | 4IN− | Inverting input of Amplifier D - referenced to same VCC− as all channels; enables 4-channel instrumentation amp topology. |
| 13 | 4IN+ | Non-inverting input of Amplifier D - supports rail-to-rail input common-mode range; usable with 0 V to VCC+ sensor outputs. |
| 14 | 4OUT | Amplifier D output - completes quad functionality; each output capable of driving 2 kΩ load to within 30 mV of rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004DR | Lower 60 μA/channel supply current, 1-MHz GBW, same SOIC-14 package, but only specified down to –40°C (not 125°C). | Preferred for ultra-low-power IoT endpoints where 125°C operation is unnecessary and 1-MHz bandwidth suffices. | Select TLV9004DR when extended temperature range is not required and sub-100 μA operation is prioritized over bandwidth. |
| MCP6004-E/SL | Higher 100 μA/channel current, 1-MHz GBW, same SOIC-14, but input offset voltage max = 4.5 mV (tighter than LMV934ID's 7.5 mV). | Better suited for precision DC-coupled applications like medical sensor front-ends requiring lower VIO at cost of reduced bandwidth. | Choose MCP6004-E/SL when input offset voltage <4.5 mV is mandatory and 1-MHz GBW meets system requirements. |
Compared with TLV9004DR and MCP6004-E/SL, LMV934ID uniquely balances 1.4-MHz bandwidth, 125°C operation, and rail-to-rail I/O in a mature SOIC-14 footprint - making it optimal for automotive and industrial designs requiring proven reliability across extreme temperatures.
