Product details
Overview
LMV934IPWE4 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 - enabling precision signal conditioning in battery-powered industrial and automotive sensor interfaces.
For engineers reviewing the LMV934IPWE4 datasheet, LMV934IPWE4 pinout, LMV934IPWE4 application, or LMV934IPWE4 equivalent, key selection considerations include its 14-pin TSSOP package, –40°C to 125°C operating range, rail-to-rail input common-mode voltage extending 200 mV beyond supplies, and verified performance at 1.8-V supply for ultra-low-power portable systems.
Technical Context
The LMV934IPWE4 integrates four independent amplifiers with Class AB output stages and input biasing that supports rail-to-rail common-mode input down to VCC− − 0.2 V and up to VCC+ + 0.2 V. Its internal architecture enables stable operation with capacitive loads up to 1000 pF while driving 600 Ω.
It operates across 1.8 V to 5 V supply range with guaranteed specifications at all voltages, including 1.4 MHz gain bandwidth at 1.8 V, 101 dB open-loop DC gain, and CMRR ≥75 dB over full temperature range - making it suitable for high-accuracy DC-coupled sensing where supply headroom is constrained.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 |
|---|---|---|---|
| TLV9054 | Higher 5-MHz GBW, 330 μA/channel supply current, same 1.8–5.5-V range and TSSOP-14 package | Better for active filters or higher-speed buffering; less suitable for sub-100-μA ultra-low-power designs | Select TLV9054 when bandwidth >1 MHz is required and power budget allows ≥3× higher current per channel |
| LMV934IDR | Identical electrical specs but in SOIC-14 package (8.65 mm × 3.91 mm vs. TSSOP's 5.0 mm × 4.4 mm); same obsolete status | Preferred where legacy SOIC footprint compatibility or manual prototyping is prioritized over space savings | Choose LMV934IDR only if existing PCB layout uses SOIC-14 and re-spin is not feasible |
Compared with TLV9054 and LMV934IDR, the LMV934IPWE4 offers the lowest quiescent current (100 μA/channel) in the smallest footprint (TSSOP-14), making it optimal for space-constrained, battery-sensitive applications where 1.4-MHz bandwidth suffices - though both alternatives remain viable for higher-speed or legacy-layout use cases.

FAQ
What is the maximum operating supply voltage for LMV934IPWE4?
The absolute maximum supply voltage (VCC+ – VCC−) for LMV934IPWE4 is 5.5 V, but the recommended operating range is 1.8 V to 5 V. Operation at 5.5 V is not guaranteed for parametric performance and may reduce reliability; TI specifies all electrical characteristics between 1.8 V and 5 V, with tested validation at 1.8 V, 2.7 V, and 5 V. The LMV934IPWE4 must never be operated outside this 1.8–5 V window in production designs.
Does LMV934IPWE4 support true rail-to-rail input common-mode voltage?
Yes, LMV934IPWE4 supports rail-to-rail input with common-mode voltage extending 200 mV beyond both supply rails - i.e., from VCC− − 0.2 V to VCC+ + 0.2 V - verified across –40°C to 125°C. This allows direct interfacing with sensors whose output exceeds the supply (e.g., thermocouples with cold-junction compensation offsets), without external level-shifting circuitry. The LMV934IPWE4 maintains CMRR ≥55 dB across this extended range.
Is LMV934IPWE4 pin-compatible with other packages in the LMV934 family?
No, LMV934IPWE4 in TSSOP-14 is not pin-compatible with LMV934ID (SOIC-14), despite sharing identical pin numbering and function mapping. Mechanical differences - including body size (5.0 × 4.4 mm vs. 8.65 × 3.91 mm), lead pitch (0.65 mm vs. 1.27 mm), and thermal pad presence - prevent direct PCB substitution. Layout redesign is required to migrate from SOIC to TSSOP; however, schematic connectivity remains identical for all 14 pins.
What is the output drive capability of LMV934IPWE4 into resistive loads?
LMV934IPWE4 delivers rail-to-rail output swing into high-impedance loads (>1 MΩ), and maintains ≥95% of full scale into 600 Ω: at 1.8 V supply, output swings from 80 mV above VCC− to 80 mV below VCC+, and at 5 V supply, from 120 mV above VCC− to 160 mV below VCC+. Short-circuit output current is ±45 mA (sourcing/sinking), verified across temperature, enabling direct drive of small relays or LEDs without external transistors.
Why is LMV934IPWE4 marked as "Not Recommended for New Designs"?
LMV934IPWE4 is designated "Not Recommended for New Designs" (NRND) by Texas Instruments due to newer alternatives like TLV9054 offering higher bandwidth and improved noise performance, though LMV934IPWE4 remains in active production for legacy program support. TI continues to manufacture and warrant LMV934IPWE4 for existing customers, with full datasheet compliance and –40°C to 125°C qualification. Aetrix Electronics maintains inventory and supply chain continuity for ongoing production needs.
