Product details

Overview

LMV934IDRE4 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 metering and portable audio interfaces.

For engineers reviewing the LMV934IDRE4 datasheet, LMV934IDRE4 pinout, LMV934IDRE4 application, or LMV934IDRE4 equivalent, key selection criteria include its –40°C to 125°C operating range, SOIC-14 package compatibility, rail-to-rail common-mode input extending 200 mV beyond supplies, and verified performance at 1.8 V with <4 mV max input offset voltage.

Technical Context

The LMV934IDRE4 integrates four independent amplifiers on a single die using complementary bipolar input stages enabling rail-to-rail input common-mode range (VICR = VCC– – 0.2 V to VCC+ + 0.2 V) and Class AB output stage supporting 600-Ω load drive with minimal ringing. Its architecture maintains 101-dB open-loop DC gain and 67° phase margin at 1.8 V.

It operates across 1.8 V to 5 V supply range with supply-current scalability (103 μA/channel at 1.8 V, 210 μA/channel at 2.7 V), supports unity-gain stable operation with up to 1000-pF capacitive loads, and achieves 0.35 V/μs slew rate at 1.8 V while maintaining THD <0.023% at 1 kHz into 600 Ω.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	1.8 V to 5 V - enables direct interface with Li-ion single-cell or two-cell battery systems without level-shifting.
Gain Bandwidth Product	1.4 MHz - supports stable closed-loop operation up to ~100 kHz with moderate gain (e.g., AV = 10).
Input Offset Voltage (max)	4 mV - ensures ≤40 mV output error in unity-gain buffer configuration at room temperature.
Supply Current per Channel	103 μA at 1.8 V - allows four-channel operation with <420 μA total quiescent draw, critical for ultra-low-power wake-up circuits.
Rail-to-Rail Output Swing	80 mV from rail into 600 Ω - preserves >95% dynamic range in 1.8-V systems, e.g., 0.08–1.72 V output span.
Common-Mode Input Range	VCC– – 0.2 V to VCC+ + 0.2 V - accepts inputs below ground or above VCC, simplifying sensor interfacing in single-supply designs.

7	2OUT	Amplifier B output - independently buffered; capable of sourcing/sinking ≥15 mA at 2.7 V.
8	VCC−	Negative supply rail (typically GND) - reference for all inputs/outputs; must be low-impedance return path.
9	3OUT	Amplifier C output - identical AC/DC specs to Pins 1 and 7; supports multi-stage filtering or parallel gain paths.
10	3IN−	Inverting input of Amp C - shares same input stage topology as Pins 2 and 6; IIO ≤40 nA ensures matched offset behavior.
11	3IN+	Non-inverting input of Amp C - enables independent sensor channel; VICR compliance verified across full temp range.
12	4IN+	Non-inverting input of Amp D - routed separately in layout to minimize crosstalk; noise voltage 60 nV/√Hz at 1 kHz.

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
TLV2464IPW	Higher supply current (550 μA/channel), wider GBW (6.4 MHz), lower VIO (1.6 mV typ), TSSOP-14 only	Better precision and speed but 5.5× higher power draw limits use in sub-1-mA systems	Select when accuracy and bandwidth outweigh battery life constraints; verify thermal dissipation in SOIC footprint replacement.
MCP6004-I/P	Lower supply current (100 μA/channel), narrower GBW (1 MHz), wider supply range (1.8–6 V), PDIP-14 and SOIC-14 options	Compatible pinout and quiescent power, but reduced bandwidth limits audio/anti-aliasing use cases	Preferred for cost-sensitive industrial controls where 1-MHz GBW suffices and DIP prototyping is needed.

Compared with TLV2464IPW and MCP6004-I/P, the LMV934IDRE4 offers optimal balance of rail-to-rail performance, ultra-low power, and SOIC-14 compatibility - making it suitable for space-constrained, battery-operated systems requiring four independent precision amplifiers without sacrificing supply voltage flexibility.

FAQ

What is the maximum operating supply voltage for LMV934IDRE4?

The absolute maximum supply voltage (VCC+ – VCC–) for LMV934IDRE4 is 5.5 V, but the recommended operating range is 1.8 V to 5 V per TI SLOS441G. Operation at 5.5 V exceeds specification limits and may compromise reliability or parametric performance. The LMV934IDRE4 is characterized and guaranteed for full functionality only within the 1.8–5-V window, including parameters like input offset voltage, gain bandwidth, and output swing.

Does LMV934IDRE4 support true rail-to-rail input at 1.8 V?

Yes, LMV934IDRE4 supports rail-to-rail input with common-mode voltage range extending 200 mV beyond both supply rails (VCC– – 0.2 V to VCC+ + 0.2 V) at 1.8 V. This is confirmed in the Electrical Characteristics table for VCC = 1.8 V, where VICR is specified as VCC– – 0.2 V to VCC+ + 0.2 V with CMRR ≥50 dB. This enables direct interfacing with sensors whose outputs swing below ground or above VDD in single-supply systems.

Is LMV934IDRE4 pin-compatible with other quad op-amps in SOIC-14 packages?

LMV934IDRE4 follows the industry-standard SOIC-14 quad op-amp pinout (1OUT, 1IN−, 1IN+, VCC+, 2IN+, 2IN−, 2OUT, VCC−, 3OUT, 3IN−, 3IN+, 4IN+, 4IN−, 4OUT), matching devices like TLV2464 and MCP6004. However, functional equivalence requires verification of supply range, bandwidth, and output drive capability - LMV934IDRE4's 1.4-MHz GBW and 100-μA/channel current differ from those parts, so electrical validation is required before drop-in replacement.

What is the typical output swing of LMV934IDRE4 into a 2-kΩ load at 1.8 V?

At 1.8 V supply and 25°C, LMV934IDRE4 delivers a typical output swing of 0.024 V to 1.775 V into a 2-kΩ load, i.e., within 24 mV of the negative rail and 25 mV of the positive rail. This is documented in the "Electrical Characteristics" table under VCC+ = 1.8 V, where VO (Low level) is 0.024 V (typ) and VO (High level) is 1.775 V (typ) for RL = 2 kΩ and VID = ±100 mV - confirming superior small-load rail-to-rail capability.

Why is LMV934IDRE4 marked 'Not Recommended for New Designs'?

LMV934IDRE4 is designated "Not Recommended for New Designs" by Texas Instruments due to newer alternatives like TLV9004 offering improved specs (lower VIO, higher GBW, smaller packages) and enhanced manufacturing support. However, LMV934IDRE4 remains in active obsolescence-phase production per TI's packaging addendum, with full datasheet validation, guaranteed parametric performance, and Aetrix Electronics supply continuity for legacy industrial and automotive programs requiring SOIC-14 form factor and proven reliability.
