Product details
Overview
LMV934IPWG4 from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for 1.8-V to 5-V single-supply operation. It delivers 1.4 MHz gain bandwidth, 100 μA per amplifier supply current, and rail-to-rail output swing within 80 mV of either rail (600 Ω load at 1.8 V), enabling precision signal conditioning in battery-powered industrial sensors and portable audio front-ends.
For engineers reviewing the LMV934IPWG4 datasheet, LMV934IPWG4 pinout, LMV934IPWG4 application, or LMV934IPWG4 equivalent, key selection criteria include its –40°C to 125°C operating range, 200 mV beyond-rail input common-mode voltage, low 4 mV max input offset voltage, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The LMV934IPWG4 employs a Class AB output stage with complementary bipolar input transistors, enabling rail-to-rail input operation down to VCC– – 0.2 V and up to VCC+ + 0.2 V. Its internal biasing supports stable operation across 1.8 V to 5 V supply rails while maintaining >75 dB CMRR over 0.2 V to (VCC – 0.2) V common-mode range.
Each of the four amplifiers features independent input stages with 65 nA typical input bias current and 103 μA typical quiescent current per channel at 1.8 V. The device achieves 67° phase margin into 600 Ω with 150 pF capacitive load, ensuring stability in sensor buffering and active filter applications without external compensation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher 6.4 MHz GBW but 230 μA/channel supply current; 1.5 V min supply; no beyond-rail input capability. | Better for higher-bandwidth active filters; unsuitable for sub-1.5 V systems or sensors requiring VCM < GND. | Select TLV2464IDR when bandwidth >2 MHz is required and power budget allows ≥2× LMV934IPWG4 consumption. |
| MCP6004-E/SL | Lower 1 µA/channel supply current but only 1 MHz GBW; rail-to-rail input/output; 1.8–6.0 V supply range. | Ideal for ultra-low-power wake-up circuits; insufficient slew rate (0.6 V/µs) for 100-kHz signal chains. | Choose MCP6004-E/SL for battery-life-critical applications where signal bandwidth <10 kHz and quiescent current dominates design. |
Compared with TLV2464IDR and MCP6004-E/SL, the LMV934IPWG4 uniquely balances 1.4 MHz bandwidth, 100 μA/channel power, and beyond-rail input capability in a TSSOP-14 package - making it optimal for cost-sensitive industrial sensor nodes requiring moderate speed and wide input range.

FAQ
What is the maximum operating temperature for the LMV934IPWG4?
The LMV934IPWG4 is characterized for continuous operation from –40°C to 125°C. This full industrial temperature range is validated per TI's SLOS441G datasheet, with electrical parameters guaranteed across this span - making the LMV934IPWG4 suitable for under-hood automotive applications and industrial motor control feedback circuits where ambient temperatures exceed 105°C.
Does the LMV934IPWG4 support true rail-to-rail input operation?
Yes, the LMV934IPWG4 supports input common-mode voltage from VCC– – 0.2 V to VCC+ + 0.2 V, confirmed in the Electrical Characteristics tables for all supply voltages (1.8 V, 2.7 V, 5 V). This "beyond-the-rails" capability allows direct interfacing with sensors whose outputs swing slightly below ground or above the positive supply - a key differentiator versus standard rail-to-rail input op-amps.
What is the typical supply current per amplifier in the LMV934IPWG4 at 1.8 V?
At 1.8 V supply and 25°C, the LMV934IPWG4 draws 103 μA per amplifier (412 μA total for all four channels), as specified in the Electrical Characteristics table under "Supply current (ICC)" at VCC+ = 1.8 V. This value increases to 116 μA/channel at 5 V, enabling accurate power budgeting for battery-powered designs across the full operating voltage range.
Can the LMV934IPWG4 drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes - at 1.8 V supply, the LMV934IPWG4 output swings to within 80 mV of both rails when driving a 600-Ω load, as documented in the "Output swing (VO)" parameter table. This performance is maintained across the full –40°C to 125°C temperature range, ensuring consistent dynamic range in precision analog front-ends for data acquisition systems.
Is the LMV934IPWG4 pin-compatible with other quad op-amps in TSSOP-14 packages?
The LMV934IPWG4 uses the industry-standard TSSOP-14 pinout for quad op-amps (per TI's SLOS441G Figure 3), matching pin functions with devices like TLV2464 and MCP6004. However, absolute pin compatibility requires verification of supply pin placement (Pins 4/VCC+, 8/VCC−), input/output ordering, and absence of enable/shutdown pins - all confirmed for LMV934IPWG4 in the provided datasheet diagrams.
