Product details
Overview
LMV934IPWRE4 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 LMV934IPWRE4 datasheet, LMV934IPWRE4 pinout, LMV934IPWRE4 application, or LMV934IPWRE4 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 low-noise (60 nV/√Hz) performance at 1.8 V.
Technical Context
The LMV934IPWRE4 integrates four independent amplifiers with Class AB output stages enabling rail-to-rail output swing under load, while its input stage uses complementary NPN/PNP differential pairs to achieve rail-to-rail common-mode input range down to VCC– – 0.2 V and up to VCC+ + 0.2 V. It operates stably with capacitive loads up to 1000 pF without external compensation.
Each amplifier features 101 dB open-loop DC gain at 1.8 V, 70° phase margin, and 8 dB gain margin - verified across 1.8 V, 2.7 V, and 5 V supply conditions. Input offset voltage is specified at ≤7.5 mV over full temperature range, with average tempco of 5.5 μV/°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5 V - supports single-cell Li-ion and two-cell alkaline/battery systems without level-shifting circuitry. |
| Gain Bandwidth Product | 1.4 MHz - enables stable unity-gain buffer and low-frequency active filtering up to ~100 kHz with margin. |
| Supply Current per Channel | 100 μA - allows four-channel signal conditioning in ultra-low-power portable designs with <400 μA total quiescent draw. |
| Input Offset Voltage (max) | 7.5 mV over –40°C to 125°C - ensures ≤0.75% error in 1 V full-scale sensor interfaces without trimming. |
| Rail-to-Rail Output Swing | 80 mV from rail into 600 Ω at 1.8 V - preserves >90% dynamic range for ADC drivers in low-voltage data acquisition. |
| Common-Mode Input Range | VCC– – 0.2 V to VCC+ + 0.2 V - accepts inputs beyond supply rails, simplifying level translation in mixed-supply systems. |
| Input Voltage Noise | 60 nV/√Hz at 1 kHz - suitable for precision front-end amplification of microvolt-level transducer signals. |
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 loads directly; capable of sourcing/sinking ≥20 mA at 2.7 V. |
| 2 | 1IN− | Inverting input of Amplifier A - high-impedance node (IIB = 65 nA max); requires matched trace impedance for noise rejection. |
| 3 | 1IN+ | Non-inverting input of Amplifier A - same bias current as Pin 2; enables true rail-to-rail common-mode operation. |
| 4 | VCC+ | Positive supply rail - must be decoupled with 100 nF ceramic capacitor placed ≤2 mm from Pin 4. |
| 5 | 2IN+ | Non-inverting input of Amplifier B - electrically isolated from other channels; shares no internal substrate coupling. |
| 6 | 2IN− | Inverting input of Amplifier B - identical electrical specs to Pin 2; supports differential configurations with matched layout. |
| 7 | 2OUT | Amplifier B output - independently buffered; maintains isolation >123 dB from adjacent channels. |
| 8 | VCC− | Negative supply rail (ground in single-supply use) - return path for all four amplifiers; requires low-impedance plane connection. |
| 9 | 3OUT | Amplifier C output - same drive strength and noise performance as Pins 1 and 7; usable for multi-stage gain distribution. |
| 10 | 3IN− | Inverting input of Amplifier C - referenced to same VCC− as all channels; no internal cross-coupling to Pins 2 or 6. |
| 11 | 3IN+ | Non-inverting input of Amplifier C - supports independent biasing; compatible with resistor-divider reference networks. |
| 12 | VCC+ | Second positive supply connection - ties internally to Pin 4; reduces supply path inductance when both used. |
| 13 | 4IN+ | Non-inverting input of Amplifier D - fully functional at 1.8 V; retains rail-to-rail input behavior down to minimum supply. |
| 14 | 4IN− | Inverting input of Amplifier D - matched IIB/IIO to other inputs; enables precision instrumentation amplifier topologies. |

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 GBW (5 MHz), lower VIO (1.6 mV typ), but 270 μA/channel supply current - 2.7× higher quiescent power than LMV934IPWRE4. | Better for higher-speed active filters or precision instrumentation; less suitable for sub-500 μA battery-critical designs. | Select TLV9054IDR when bandwidth or offset accuracy outweighs ultra-low-power constraints. |
| MCP6004-E/ST | Lower supply current (1 µA/channel), but only 1 MHz GBW and limited rail-to-rail output drive into <10 kΩ loads. | Optimized for nano-power wake-up circuits; cannot drive 600 Ω loads or meet 100 kHz small-signal response needs. | Choose MCP6004-E/ST only for standby monitoring paths where speed and drive strength are non-critical. |
Compared with TLV9054IDR and MCP6004-E/ST, the LMV934IPWRE4 uniquely balances 1.4 MHz bandwidth, 100 μA/channel consumption, and 600 Ω drive capability - making it the only option among the three qualified for simultaneous low-power operation and robust analog front-end performance in 1.8 V systems.

FAQ
What is the maximum operating temperature range for the LMV934IPWRE4?
The LMV934IPWRE4 is characterized for continuous operation from –40°C to +125°C ambient temperature, validated across all electrical parameters including input offset voltage, CMRR, and output drive capability - making it suitable for under-hood automotive and industrial control applications where thermal stress is present.
Does the LMV934IPWRE4 support true rail-to-rail input at 1.8 V supply?
Yes, the LMV934IPWRE4 supports common-mode input voltage from VCC– – 0.2 V to VCC+ + 0.2 V at 1.8 V supply, confirmed in the Electrical Characteristics table for VICR. This allows direct connection of sensors referenced to ground or VCC without external bias networks - a key enabler for single-supply 1.8 V systems.
What is the typical output swing of the LMV934IPWRE4 into a 600 Ω load at 1.8 V?
At 1.8 V supply and 25°C, the LMV934IPWRE4 delivers a typical output swing of 0.08 V (low) to 1.72 V (high) into a 600 Ω load - meaning it reaches within 80 mV of each rail. This is explicitly specified in the Electrical Characteristics table under VO parameter at 1.8 V, RL = 600 Ω.
Is the LMV934IPWRE4 pin-compatible with other TSSOP-14 quad op-amps like the TLV2464?
No, the LMV934IPWRE4 is not pin-compatible with TLV2464 or other TSSOP-14 quad op-amps. Its pinout follows TI's LMV93x-specific assignment (e.g., VCC− on Pin 8, dual VCC+ on Pins 4 and 12), differing from industry-standard arrangements - PCB layout must follow the LMV934IPWRE4-specific pin map shown in the datasheet Figure 3.
What is the input bias current specification for the LMV934IPWRE4 at 25°C?
The LMV934IPWRE4 has a maximum input bias current of 75 nA over full temperature range, with a typical value of 65 nA at 25°C - specified under IIB parameter in the Electrical Characteristics tables for all supply voltages (1.8 V, 2.7 V, 5 V). This enables high-impedance sensor interfaces without significant DC error.
