Product details
Overview
LMV824DRG4 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 LMV824DRG4 datasheet, LMV824DRG4 pinout, LMV824DRG4 application, or LMV824DRG4 equivalent, key selection criteria include its rail-to-rail output swing (4.85 V at 5 V supply, RL = 2 kΩ), input common-mode range extending to ground, –40°C to 85°C operating temperature, and SOIC-14 package compatibility with legacy PCB layouts.
Technical Context
The LMV824DRG4 implements a CMOS input stage with rail-to-rail output using complementary bipolar output transistors, eliminating crossover distortion. Its architecture supports single-supply operation down to 2.5 V while maintaining >70 dB CMRR and PSRR across 1 kHz–100 kHz.
Each of the four amplifiers operates independently with >135 dB amplifier-to-amplifier isolation at 1 kHz. The device exhibits stable unity-gain performance with 64.2° phase margin into 600 Ω loads and 22 pF capacitive loads, per TI SLOS434I Rev. July 2006.
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 - sufficient for 100-kHz full-scale sine waves up to ~3 Vpp without distortion. |
| Input Offset Voltage | 1 mV typ (25°C), ≤4 mV over –40°C to 85°C - ensures <0.1% error in 12-bit sensor front-end designs. |
| Output Swing | 0.1 V from rail (low) / 0.15 V from rail (high) at 5 V, RL = 2 kΩ - maximizes dynamic range in single-supply ADC driver stages. |
| Supply Current (All Channels) | 1 mA typ at 5 V - allows four-channel buffering in sub-10-mA system power budgets. |
| Common-Mode Input Range | –0.2 V to 4.3 V at 5 V supply - includes ground, enabling direct connection to unipolar sensor outputs. |
Pinout & Package
LMV824DRG4 is housed in a 14-pin SOIC (D package) with standard 1.27 mm pitch, 8.65 mm × 3.91 mm footprint, and exposed pad not present. Pinout matches TI's industry-standard quad op-amp configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Drives external load; rail-to-rail swing supports full 0–5 V signal range. |
| 2 | Channel 1 Inverting Input | Accepts feedback or differential input; high impedance (>10¹² Ω) minimizes loading on source. |
| 3 | Channel 1 Non-Inverting Input | High-impedance sensor interface point; common-mode range includes ground. |
| 4 | Ground / Negative Supply | Reference node for all channels; must be low-impedance return path for output currents. |
| 5 | Channel 2 Non-Inverting Input | Independent input for second channel; electrically isolated from other inputs. |
| 6 | Channel 2 Inverting Input | Feedback node for channel 2; no crosstalk coupling to channels 1, 3, or 4. |
| 7 | Channel 2 Output | Independent output stage; capable of sourcing/sinking ±20 mA at 5 V. |
| 8 | Positive Supply (VCC+) | Power input for all four amplifiers; bypass capacitor required at pin for stability. |
| 9 | Channel 3 Output | Third independent output; identical AC/DC specs to pins 1 and 7. |
| 10 | Channel 3 Inverting Input | Matches pin 2 functionality; no shared internal nodes with other channels. |
| 11 | Channel 3 Non-Inverting Input | Matches pin 3 functionality; supports DC-coupled sensor interfaces. |
| 12 | Channel 4 Non-Inverting Input | Fourth channel input; fully specified across –40°C to 85°C temperature range. |
| 13 | Channel 4 Inverting Input | Feedback node for final channel; maintains >135 dB isolation from adjacent channels. |
| 14 | Channel 4 Output | Final output; rail-to-rail swing enables direct drive of SAR ADC reference buffers. |

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 | Identical electrical specs and pinout; G4 suffix denotes RoHS-compliant lead finish (Pb-free NiPdAu), while DR lacks this designation. | No functional difference; both rated for –40°C to 85°C and packaged in SOIC-14. | Select LMV824DRG4 when RoHS compliance and Pb-free assembly are mandatory; otherwise LMV824DR is functionally interchangeable. |
| TLV2464CDR | Higher supply current (1.4 mA vs. 1 mA), lower GBW (6.4 MHz vs. 5.5 MHz), wider input voltage range (rail-to-rail input), and same SOIC-14 package. | Better suited for rail-to-rail input applications (e.g., photodiode transimpedance amps), but consumes 40% more power. | Choose TLV2464CDR only if rail-to-rail input is required; LMV824DRG4 remains optimal for output swing–critical, low-power designs. |
Compared with LMV824DR and TLV2464CDR, the LMV824DRG4 provides the lowest quiescent power among SOIC-14 quad op-amps with guaranteed rail-to-rail output and <4 mV offset over temperature - making it ideal for battery-sensitive, precision-signal applications where input rail-to-rail capability is not required.

FAQ
What is the operating temperature range for LMV824DRG4?
The LMV824DRG4 is characterized for operation from –40°C to +85°C ambient temperature. This range is confirmed in the "Recommended Operating Conditions" table of the TI SLOS434I datasheet (Rev. July 2006), and applies to all electrical specifications unless otherwise noted. It is not rated for the extended –40°C to +125°C range offered by the LMV824I variants.
Does LMV824DRG4 support true rail-to-rail input?
No, LMV824DRG4 features rail-to-rail *output* but not rail-to-rail *input*. Its common-mode input voltage range extends from –0.2 V to (VCC+ – 0.3 V) - which includes ground but does not reach the positive rail. For rail-to-rail input capability, consider alternatives like TLV2464CDR, but note that LMV824DRG4 prioritizes output swing and low supply current over input range.
What is the maximum capacitive load LMV824DRG4 can drive stably?
LMV824DRG4 maintains stability with up to 22 pF capacitive load when configured for unity gain and driving a 600 Ω resistive load, as verified in Figure 17 of the SLOS434I datasheet. Driving larger capacitive loads (e.g., >100 pF) requires external isolation resistance or gain adjustment to preserve ≥60° phase margin and prevent peaking or oscillation.
Is LMV824DRG4 pin-compatible with other quad op-amps in SOIC-14 packages?
Yes, LMV824DRG4 uses the industry-standard SOIC-14 pinout for quad op-amps (e.g., matching LM2902, TLV2464, and MCP6004). Pin 1 is Channel 1 Output, Pin 4 is GND, Pin 8 is VCC+, and Pin 14 is Channel 4 Output - enabling drop-in replacement in existing layouts designed for compatible quad op-amps with identical gain-bandwidth and output drive requirements.
What does the 'G4' suffix signify in LMV824DRG4?
The 'G4' suffix in LMV824DRG4 indicates TI's RoHS-compliant, lead-free finish: matte tin over nickel-palladium-gold (NiPdAu) on the leads. This replaces traditional SnPb plating and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL 3) requirements. The underlying silicon, electrical specs, and packaging dimensions remain identical to the non-G4 LMV824DR variant.
