Product details
Overview
LMV824DGVRE4 from Texas Instruments is a quad, rail-to-rail output operational amplifier optimized for low-voltage (2.5 V to 5.5 V), low-power applications. It delivers 5.5 MHz gain bandwidth, 1.9 V/μs slew rate, and 1 mA typical supply current at 5 V - enabling precision signal conditioning in space-constrained portable electronics such as medical sensors and battery-powered instrumentation.
For engineers reviewing the LMV824DGVRE4 datasheet, LMV824DGVRE4 pinout, LMV824DGVRE4 application, or LMV824DGVRE4 equivalent, key selection criteria include its rail-to-rail output swing (4.85 V at 5 V supply, RL = 2 kΩ), –40°C to 85°C operating range, 14-pin TVSOP package, and absence of crossover distortion in audio and sensor front-end designs.
Technical Context
The LMV824DGVRE4 integrates four independent high-fidelity op-amps sharing a common 2.5–5.5 V single-supply rail. Its input stage supports common-mode voltage down to ground, and its output stage drives loads as low as 600 Ω while maintaining rail-to-rail swing - critical for interfacing with ADCs and low-voltage microcontrollers.
It features 135 dB amplifier-to-amplifier isolation and 42 nV/√Hz input voltage noise at 1 kHz, making it suitable for multi-channel sensing where crosstalk and noise coupling must be minimized. Phase margin remains stable (≥64.2°) across load conditions up to 100 kΩ and capacitive loads up to 200 pF.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct operation from Li-ion, 3.3 V, or 5 V rails without regulation |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~55 at 100 kHz with stable phase margin |
| Slew Rate | 1.9 V/μs typ at 5 V - sufficient for 100-kSPS 12-bit SAR ADC driving and audio preamplification |
| Input Offset Voltage | 1 mV typ, 4 mV max (–40°C to 85°C) - ensures ≤1 LSB error in 12-bit systems with 2.5 V reference |
| Output Swing | 0.1 V from rail (low), 0.15 V from rail (high) at 5 V/2 kΩ - maximizes dynamic range into 3.3 V logic or ADC inputs |
| Supply Current | 1 mA typ (all four amps) at 5 V - allows 10+ channels in <10 mA total analog front-end budget |
| Input Bias Current | 40 nA typ at 25°C - permits use with high-impedance pH or photodiode sensors without significant offset drift |
Pinout & Package
LMV824DGVRE4 is housed in a 14-pin Thin Very Small Outline Package (TVSOP), 3.6 mm × 4.9 mm footprint, 0.65 mm pitch, with exposed thermal pad for enhanced power dissipation in compact PCB layouts.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | Same electrical specs; SOIC-14 package (8.65 mm × 3.91 mm) vs. TVSOP-14 (3.6 mm × 4.9 mm) | SOIC variant requires ~2.2× more PCB area; better thermal mass for higher ambient temperatures | Select LMV824DR if board space permits and thermal management prioritizes package robustness over miniaturization |
| TLV2464CDR | Lower 6.4 MHz GBW, 1.6 V/μs slew rate, 0.55 mA supply current; wider –40°C to 125°C temp range | Optimized for ultra-low-power, extended-temp industrial control; less suited for audio or fast-sampling systems | Choose TLV2464CDR when operating above 85°C or when sub-600 μA per amp is mandatory |
Compared with LMV824DR and TLV2464CDR, the LMV824DGVRE4 uniquely balances compact TVSOP packaging, 5.5 MHz bandwidth, and 1.9 V/μs slew rate - making it optimal for battery-powered, space-constrained designs requiring both speed and precision within commercial temperature limits.

FAQ
What is the operating temperature range for LMV824DGVRE4?
The LMV824DGVRE4 is characterized for operation from –40°C to +85°C. This range is validated per TI's SLOS434I datasheet and applies to all electrical specifications including input offset voltage, gain bandwidth, and output swing. It is not rated for the extended –40°C to +125°C range offered by the LMV824I variants.
Does LMV824DGVRE4 support true rail-to-rail input?
No, LMV824DGVRE4 does not support rail-to-rail input. Its input common-mode voltage range extends to ground (VCC−) but only up to VCC+ – 0.2 V at 25°C. The datasheet specifies VICR = –0.2 V to 4.2 V at 5 V supply, meaning the input cannot accept signals at the positive rail - only the output swings rail-to-rail.
What is the maximum capacitive load LMV824DGVRE4 can drive stably?
LMV824DGVRE4 maintains stability with capacitive loads up to 200 pF when driving a 10 kΩ resistive load, as confirmed by Figure 18 in the SLOS434I datasheet. For loads >100 pF, TI recommends adding a 10–100 Ω series resistor between the output and capacitor to preserve phase margin above 60°.
Is LMV824DGVRE4 pin-compatible with other LMV824 variants?
Yes, LMV824DGVRE4 shares identical pinout and functionality with all LMV824 variants (e.g., LMV824DR, LMV824PW, LMV824IDGVR), as confirmed by the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram. All use the same 14-pin arrangement: 1OUT, 1IN−, 1IN+, VCC+, 2IN+, 2IN−, 2OUT, 4OUT, 4IN−, 4IN+, GND/VCC−, 3IN+, 3IN−, 3OUT.
What is the typical input offset voltage drift over temperature for LMV824DGVRE4?
The LMV824DGVRE4 has an average input offset voltage temperature coefficient (αVIO) of 1 μV/°C, as specified in the 2.7-V and 5-V electrical characteristics tables. This low drift ensures offset remains within ±3 μV over a 30°C ambient change - critical for precision DC-coupled measurement circuits using LMV824DGVRE4.
