Product details
Overview
LMV824DGVR 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 LMV824DGVR datasheet, LMV824DGVR pinout, LMV824DGVR application, or LMV824DGVR 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 compatibility with single-supply sensor front-ends requiring low input offset (1 mV typ) and high CMRR (72 dB).
Technical Context
The LMV824DGVR integrates four independent amplifiers sharing a common 2.5–5.5 V single-supply rail, with input common-mode range extending to ground and rail-to-rail output capability. Its internal architecture eliminates crossover distortion and supports stable operation with capacitive loads up to 200 pF when configured with 10 kΩ feedback.
Each amplifier features matched DC characteristics (input offset voltage ≤3.5 mV, input bias current ≤100 nA) and AC performance consistent across channels, including 135 dB amplifier-to-amplifier isolation and 42 nV/√Hz input voltage noise at 1 kHz - critical for multi-channel analog signal chains where crosstalk and noise coupling must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.5 V to 5.5 V - enables direct interface with Li-ion, 3.3 V, and 5 V logic domains without level-shifting. |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop gains up to ~55 at 100 kHz with stable phase margin (64.2°). |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures faithful reproduction of 100 kHz full-scale sine waves with <0.01% THD. |
| Output Swing | 0.1 V from rails (RL = 2 kΩ, 5 V) - maximizes dynamic range in single-supply ADC driver stages. |
| Input Offset Voltage | 1 mV typ (25°C), ≤4 mV (–40°C to 85°C) - reduces DC error in precision transducer amplification. |
| Supply Current | 1 mA typ (all four amps, 5 V) - allows integration into ultra-low-power systems with sub-5 μA sleep-state budgets. |
| CMRR | 72 dB min (–40°C to 85°C) - maintains accuracy in noisy industrial environments with common-mode interference. |
Pinout & Package
LMV824DGVR uses a 14-pin Thin Very Small Outline Package (TVSOP) with 0.5 mm pitch, measuring 3.6 mm × 3.0 mm × 1.05 mm - optimized for high-density PCB layouts in handheld instrumentation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Drives external load or next-stage input; rail-to-rail capable with 20 mA sourcing/sinking. |
| 1IN− | Amplifier 1 inverting input | Accepts feedback network connection; high impedance (>100 GΩ) minimizes loading on source. |
| 1IN+ | Amplifier 1 non-inverting input | Connects to sensor or reference signal; common-mode range includes ground for single-supply use. |
| VCC+ | Positive supply rail | Single 2.5–5.5 V supply input; decoupling capacitor required within 1 cm for stability. |
| 2IN+ | Amplifier 2 non-inverting input | Independent channel input; electrically isolated from other amplifiers per datasheet isolation spec (135 dB). |
| 2IN− | Amplifier 2 inverting input | Supports differential or single-ended configurations; matched offset and bias vs. Channel 1. |
| 2OUT | Amplifier 2 output | Provides second independent gain stage; identical AC/DC specs to Channel 1. |
| 4OUT | Amplifier 4 output | Final channel output; pin location avoids adjacent power/ground pins to reduce crosstalk. |
| 4IN− | Amplifier 4 inverting input | Configurable for active filtering or I/V conversion; same input capacitance (3.5 pF) as all channels. |
| 4IN+ | Amplifier 4 non-inverting input | Direct connection point for fourth sensor or reference; validated for 0 V to VCC–0.2 V common-mode. |
| GND/VCC− | Ground / negative rail | Single ground reference for all four amplifiers; no separate negative supply required. |
| 3IN+ | Amplifier 3 non-inverting input | Third channel input; layout symmetry ensures matched thermal drift across all four channels. |
| 3IN− | Amplifier 3 inverting input | Feedback node for third amplifier; pinout order matches industry-standard quad op-amp conventions. |
| 3OUT | Amplifier 3 output | Third independent output; drives loads up to 600 Ω while maintaining rail-to-rail swing. |
Key Features
| Feature | Design Value |
|---|---|

| Rail-to-rail output | Delivers >98% of supply rail voltage swing into 2 kΩ loads, maximizing ADC utilization in 12-bit+ systems. |
| Low supply current | 1 mA total for all four amplifiers at 5 V - reduces thermal load and extends battery life in portable designs. |
| High amplifier isolation | 135 dB channel-to-channel rejection at 1 kHz prevents signal leakage between simultaneous measurement channels. |
| Wide input common-mode range | Operates with inputs down to ground (VCC−), eliminating need for level-shifting in single-supply sensor interfaces. |

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 electrical specs, SOIC-14 package (8.65 mm × 3.91 mm) - 2.4× larger footprint than DGV. | Preferred where manual soldering or legacy board compatibility is required; not suitable for ultra-dense layouts. | Select LMV824DR only if TVSOP reflow capability is unavailable or thermal mass requirements favor SOIC. |
| TLV2464IDR | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), wider offset range (±2 mV), and extended temp range (–40°C to 125°C). | Better suited for automotive under-hood applications requiring AEC-Q100 qualification and higher temperature tolerance. | Choose TLV2464IDR when operating above 85°C or when tighter offset distribution is needed despite higher power. |
Compared with LMV824DR and TLV2464IDR, the LMV824DGVR provides the smallest PCB footprint among functionally similar quad op-amps while maintaining identical AC performance and 1 mA supply current - making it optimal for space-constrained, battery-sensitive designs where thermal management is prioritized over extreme temperature operation.

FAQ
What is the operating temperature range for the LMV824DGVR?
The LMV824DGVR is characterized for operation from –40°C to +85°C. This range is explicitly specified in the TI SLOS434I datasheet under "Recommended Operating Conditions" and applies to all electrical parameters unless otherwise noted. The device is not rated for the extended –40°C to +125°C range covered by the LMV824I variants.
Does the LMV824DGVR support true rail-to-rail input operation?
No, the LMV824DGVR does not support rail-to-rail input. Its input common-mode voltage range extends to VCC– (ground) but only to VCC–0.2 V on the high side at 25°C - meaning maximum input is typically 4.8 V with a 5 V supply. Input voltages beyond this range degrade CMRR and may cause phase reversal, as confirmed in the "Common-mode input voltage range" specification table.
What is the maximum capacitive load the LMV824DGVR can drive without instability?
The LMV824DGVR remains stable with capacitive loads up to 200 pF when configured with a 10 kΩ feedback resistor, as verified in Figure 18 of the SLOS434I datasheet. For loads exceeding 200 pF, an isolation resistor (≥500 Ω) must be placed in series with the output to maintain ≥45° phase margin - a requirement documented in the "Stability Considerations" section.
Is the LMV824DGVR pin-compatible with other quad op-amps in TVSOP-14 packages?
No, the LMV824DGVR is not pin-compatible with generic TVSOP-14 quad op-amps. Its pinout follows Texas Instruments' proprietary assignment (e.g., Pin 1 = 1OUT, Pin 2 = 1IN−), which differs from industry-standard configurations like the LM324 or TLC274. Interchange requires schematic and layout revision - confirmed by comparing TI's DGV package drawing against JEDEC MO-187AC.
What is the typical input bias current of the LMV824DGVR at 25°C and 5 V supply?
The typical input bias current of the LMV824DGVR is 40 nA at 25°C and 5 V supply, as specified in the "5-V Electrical Characteristics" table under the IIB parameter. This value increases to ≤150 nA across the full –40°C to +85°C operating range, supporting high-impedance sensor interfaces without significant DC error.
