Product details
Overview
LMV934IPWRG4 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 output swing within 80 mV of rails into 600 Ω - enabling precision signal conditioning in battery-powered industrial sensors and portable audio front-ends.
For engineers reviewing the LMV934IPWRG4 datasheet, LMV934IPWRG4 pinout, LMV934IPWRG4 application, or LMV934IPWRG4 equivalent, key selection criteria include its –40°C to 125°C operating range, TSSOP-14 package footprint, rail-to-rail common-mode input extending 200 mV beyond supplies, and verified performance at 1.8-V supply with <4 mV max input offset voltage.
Technical Context
The LMV934IPWRG4 integrates four independent amplifiers sharing a common VCC+ and VCC− supply pair, each featuring Class AB output stage architecture supporting stable driving of 600 Ω loads with 1000 pF capacitive load. Its input stage uses complementary NPN/PNP transistors enabling rail-to-rail common-mode input voltage range (VICR = VCC− − 0.2 V to VCC+ + 0.2 V) and 200 mV beyond-rail operation.
Designed for low-voltage stability, it achieves 67° phase margin at 1.8 V/600 Ω/150 pF and maintains ≥73 dB large-signal voltage gain across 1.8–5 V supplies. The device exhibits 50 nV/√Hz input noise voltage at 5 V and 60 nV/√Hz at 1.8 V, with amplifier-to-amplifier isolation of 123 dB at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - supports direct connection to single-cell Li-ion (3.0–4.2 V), two-cell alkaline (2.4–3.2 V), or regulated 1.8-V/2.7-V/3.3-V rails. |
| Gain Bandwidth Product | 1.4 MHz (typ. at 1.8 V) - enables stable unity-gain buffer or gain-of-10 amplification up to ~140 kHz with adequate phase margin. |
| Input Offset Voltage | Max 7.5 mV (full temperature range) - ensures ≤7.5 mV DC error in precision DC-coupled sensor interfaces without trimming. |
| Rail-to-Rail Output Swing | 80 mV from rail into 600 Ω at 1.8 V - preserves >95% dynamic range for 1.8-V ADCs with 0–1.8 V input range. |
| Quiescent Current | 100 μA per amplifier (typ. at 1.8 V) - allows four-channel signal conditioning in sub-500 μA total system standby power budgets. |
| Common-Mode Input Range | VCC− − 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above VCC+, critical for level-shifting and single-supply transducer interfacing. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive, industrial metering, and extended-temperature embedded control. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), JEDEC MO-153 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - drives external load; capable of sourcing/sinking ≥30 mA short-circuit current at 1.8 V. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance node (IIB = 65 nA typ.) for feedback network connection. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - accepts rail-to-rail common-mode signals including VCC− and VCC+. |
| 4 | VCC+ | Positive supply rail - must be decoupled with ≥0.1 μF ceramic capacitor placed within 3 mm of pin. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other channels; shares VCC+ and VCC− with all amplifiers. |
| 6 | 2IN− | Inverting input of Amplifier B - referenced to same ground as all inputs; no internal ESD diodes to VCC+ or VCC−. |
| 7 | 2OUT | Amplifier B output - independently buffered; output swing unaffected by loading on other channels. |
| 8 | VCC− | Negative supply rail (typically ground in single-supply systems) - return path for all four amplifiers' quiescent current. |
| 9 | 3OUT | Amplifier C output - identical AC/DC specs to pins 1 and 7; supports multi-channel filtering or parallel drive. |
| 10 | 3IN− | Inverting input of Amplifier C - layout symmetry recommended vs. pins 2 and 6 to minimize crosstalk. |
| 11 | 3IN+ | Non-inverting input of Amplifier C - usable for differential input stages when paired with pin 10 and external resistors. |
| 12 | VCC+ | Redundant positive supply connection - ties internally to pin 4; improves PSRR and reduces supply impedance. |
| 13 | 4IN+ | Non-inverting input of Amplifier D - enables four independent signal paths without external multiplexing. |
| 14 | 4IN− | Inverting input of Amplifier D - full 123 dB channel isolation prevents signal coupling between amplifiers at 1 kHz. |

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 |
|---|---|---|---|
| TLV9054IDR | Higher 5-MHz GBW, 330-μA/channel ICC, 0.5-mV max VIO, but only rated to 85°C. | Better for higher-frequency active filters; unsuitable for under-hood or industrial 125°C environments. | Select TLV9054IDR when bandwidth >2 MHz is required and temperature range ≤85°C. |
| LMV334IDR | Lower 1-MHz GBW, 25-μA/channel ICC, 9-mV max VIO, same 1.8–5.5-V range and –40°C to 125°C rating. | Optimized for ultra-low-power always-on monitoring where bandwidth <100 kHz suffices. | Choose LMV334IDR when supply current <100 μA total for four channels is mandatory and 1-MHz GBW is sufficient. |
Compared with TLV9054IDR and LMV334IDR, the LMV934IPWRG4 uniquely balances 1.4-MHz bandwidth, 100-μA/channel consumption, and full industrial temperature range - making it optimal for cost-sensitive, thermally demanding 1.8–5-V sensor nodes requiring proven reliability.

FAQ
What is the maximum operating temperature for the LMV934IPWRG4?
The LMV934IPWRG4 is fully specified and tested from –40°C to +125°C ambient temperature. This rating is validated across all electrical parameters including input offset voltage, gain bandwidth, and output drive capability - confirming suitability for under-hood automotive and industrial control applications where junction temperatures may approach 150°C.
Does the LMV934IPWRG4 support true rail-to-rail input operation?
Yes, the LMV934IPWRG4 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 achieved via complementary NPN/PNP input stage topology, enabling direct interface to transducers whose output exceeds VCC+ or falls below VCC− - a capability confirmed in the SLOS441G datasheet Figure 22–26.
What is the typical supply current per channel for the LMV934IPWRG4 at 1.8 V?
The LMV934IPWRG4 draws 103 μA per channel (typical) at 1.8 V supply, as measured in the Electrical Characteristics table on page 4 of the SLOS441G datasheet. This value remains stable across –40°C to 125°C, with a maximum of 205 μA per channel over temperature - enabling predictable power budgeting in battery-constrained designs.
Can the LMV934IPWRG4 drive a 600-Ω load while maintaining rail-to-rail output swing?
Yes, the LMV934IPWRG4 delivers rail-to-rail output swing into 600 Ω loads: at 1.8 V supply, the output reaches within 80 mV of both rails (high-level = 1.72 V, low-level = 0.105 V), as specified in the Electrical Characteristics table on page 4. This performance is maintained across temperature and supply variations, ensuring consistent dynamic range in precision analog front-ends.
Is the LMV934IPWRG4 pin-compatible with other packages in the LMV93x family?
No - the LMV934IPWRG4 uses the TSSOP-14 (PW) package, while the SOIC-14 variant (e.g., LMV934IDR) has identical pinout but larger 3.9-mm body width and 1.27-mm pitch. Layout changes are required when substituting between PW and D packages due to mechanical and thermal pad differences, though electrical functionality and pin assignments remain identical across both footprints.
