Product details
Overview
LMV824IDGVR 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 data acquisition systems.
For engineers reviewing the LMV824IDGVR datasheet, LMV824IDGVR pinout, LMV824IDGVR application, or LMV824IDGVR equivalent, key selection criteria include its –40°C to 125°C operating range, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), input common-mode range extending to ground, and TVSOP-14 (DGV) package compatibility with high-density PCB layouts.
Technical Context
The LMV824IDGVR integrates four independent amplifiers sharing a single 2.5–5.5 V supply, each featuring complementary input stages that eliminate crossover distortion and support true rail-to-rail output swing. Its internal architecture enables stable operation with capacitive loads up to 200 pF while maintaining ≥64.2° phase margin at 5 V and 600 Ω load.
Designed for single-supply operation, it accepts input voltages from VCC− (GND) to VCC+, supports sourcing/sinking up to 45 mA per channel (at 5 V), and achieves 135 dB amplifier-to-amplifier isolation - critical for multi-channel sensor front-ends where crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic without level-shifting. |
| Gain Bandwidth Product | 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 - ensures <1% THD for 10 kHz sine waves up to 4.1 VP-P output swing. |
| Input Offset Voltage | 1 mV typ, 5.5 mV max over –40°C to 125°C - maintains accuracy in precision DC-coupled sensor amplification. |
| Output Swing | Within 100 mV of rails (at 2 kΩ, 5 V) - maximizes dynamic range in single-supply data converters and analog front-ends. |
| Supply Current (per amp) | 250 μA typ at 5 V - allows four-channel operation at <1 mA total, ideal for always-on battery monitoring. |
| Common-Mode Input Range | Extends to VCC− (GND) - permits direct connection of grounded-sensor outputs without biasing resistors. |
Pinout & Package
LMV824IDGVR is housed in a 14-pin Thin Very Small Outline Package (TVSOP-14, package code DGV), measuring 3.6 mm × 3.0 mm × 1.05 mm with 0.5 mm lead pitch. This thermally enhanced, surface-mount package supports automated assembly and offers improved thermal resistance (θJA = 127°C/W) versus standard SOIC-14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Delivers rail-to-rail voltage output; requires local decoupling if driving capacitive loads >100 pF. |
| 1IN− | Amplifier 1 inverting input | Differential input node; matched impedance routing recommended to minimize offset drift from layout asymmetry. |
| 1IN+ | Amplifier 1 non-inverting input | Accepts signals from 0 V to VCC; no external bias needed for ground-referenced sources. |
| VCC+ | Positive supply | Single 2.5–5.5 V supply input; must be bypassed with 100 nF ceramic capacitor near pin. |
| 2IN+ | Amplifier 2 non-inverting input | Independent input for second channel; shares same supply and ground with other amplifiers. |
| 2IN− | Amplifier 2 inverting input | Paired with 2IN+ for differential or single-ended configurations; layout symmetry critical for CMRR. |
| 2OUT | Amplifier 2 output | Electrically isolated from 1OUT; 135 dB channel-to-channel isolation prevents crosstalk in multi-signal paths. |
| 4OUT | Amplifier 4 output | Final channel output; identical electrical specs to 1OUT; pin placement minimizes trace length in compact layouts. |
| 4IN− | Amplifier 4 inverting input | Supports unity-gain stable configuration; no external compensation required for standard feedback networks. |
| 4IN+ | Amplifier 4 non-inverting input | Enables high-impedance sensing; input bias current ≤150 nA allows use with high-Z transducer sources. |
| GND/VCC− | Ground / negative supply | Reference node for all channels; must connect to low-impedance system ground plane to maintain PSRR. |
| 3IN+ | Amplifier 3 non-inverting input | Third channel input; supports simultaneous multi-sensor readout without multiplexing latency. |
| 3IN− | Amplifier 3 inverting input | Configurable for active filtering or instrumentation topologies; input common-mode range includes GND. |
| 3OUT | Amplifier 3 output | Provides fourth independent output; full rail-to-rail swing enables direct ADC driver interface. |
Key Features
| Feature | Design Value |

| 1.9 V/μs slew rate | Enables accurate reproduction of fast transients in pulse-width modulated motor control feedback loops. |
| –40°C to 125°C operation | Validated for under-hood automotive, industrial PLC, and outdoor IoT sensor nodes without derating. |
| Low 1 mA supply current (quad) | Reduces thermal load in sealed enclosures and extends battery life in portable diagnostic equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV824DR | Same core specs but rated for –40°C to 85°C; SOIC-14 package (larger footprint, higher θJA = 86°C/W). | Not suitable for under-hood or extended-temperature industrial environments requiring 125°C operation. | Select LMV824DR only for cost-sensitive commercial-grade designs where temperature range is limited. |
| TLV2464IDR | Higher 6.4 MHz GBW and lower 0.025 mV/°C offset drift, but 1.2 mA supply current and no guaranteed 125°C operation. | Preferred for ultra-low-drift precision instrumentation; less optimal for battery-constrained systems. | Choose TLV2464IDR when long-term DC stability outweighs quiescent current and temperature requirements. |
Compared with LMV824DR and TLV2464IDR, LMV824IDGVR uniquely balances extended temperature capability (–40°C to 125°C), ultra-small TVSOP-14 footprint, and sub-1 mA quad-channel consumption - making it the optimal choice for thermally demanding, space-constrained embedded systems.

FAQ
What is the operating temperature range of the LMV824IDGVR?
The LMV824IDGVR is characterized for operation from –40°C to +125°C, making it suitable for under-hood automotive, industrial control, and outdoor IoT applications where ambient temperatures exceed standard commercial grade limits. This extended range is confirmed in TI's SLOS434I datasheet revision July 2006 and applies specifically to the "I" suffix variant, including LMV824IDGVR.
Does the LMV824IDGVR support rail-to-rail input operation?
The LMV824IDGVR supports rail-to-rail *output* swing but has an input common-mode voltage range extending from VCC− (GND) to VCC+ − 0.2 V - meaning it accepts inputs down to ground but not fully to the positive rail. This allows direct interfacing with grounded sensors while maintaining high CMRR (>70 dB) across the usable input range.
What package type is used for the LMV824IDGVR?
The LMV824IDGVR uses the TVSOP-14 (Thin Very Small Outline Package) with package code DGV, a 14-pin surface-mount package measuring 3.6 mm × 3.0 mm × 1.05 mm and 0.5 mm lead pitch. This compact, thermally efficient package is explicitly listed in TI's ordering table and package addendum for LMV824IDGVR.
Can the LMV824IDGVR drive capacitive loads?
Yes - the LMV824IDGVR maintains stability with capacitive loads up to 200 pF when configured with appropriate feedback (e.g., 600 Ω series resistor at output). Phase margin remains ≥60° at 2.7 V and ≥64.2° at 5 V with 600 Ω load, as verified in Figures 16–21 of the SLOS434I datasheet. For larger loads, external isolation resistance is recommended.
Is the LMV824IDGVR pin-compatible with other LMV824 variants?
Yes - the LMV824IDGVR shares identical pinout with all LMV824 variants (e.g., LMV824DR, LMV824D, LMV824IPWR) across SOIC-14, TSSOP-14, and TVSOP-14 packages. Pin functions (1OUT, 1IN−, 1IN+, VCC+, etc.) are standardized per Figure 1 and the top-view diagram in the datasheet, enabling drop-in replacement within the same package family.
