Product details
Overview
LMV824IPWG4 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 LMV824IPWG4 datasheet, LMV824IPWG4 pinout, LMV824IPWG4 application, or LMV824IPWG4 equivalent, key selection considerations include its –40°C to 125°C operating range, rail-to-rail output swing (4.85 V high / 0.1 V low at 5 V, RL = 2 kΩ), input offset voltage ≤5.5 mV over temperature, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The LMV824IPWG4 integrates four independent amplifiers sharing a common 2.5–5.5 V single-supply rail, with input common-mode range extending to ground and output swing within 100 mV of each rail under 2 kΩ load. Its internal architecture eliminates crossover distortion and supports stable unity-gain operation with ≥64.2° phase margin at 5 V and 600 Ω load.
Designed for cost-sensitive industrial and consumer systems, it maintains consistent AC performance across voltage (2.7 V/5 V) and temperature (–40°C to 125°C), with amplifier-to-amplifier isolation of 135 dB and PSRR >70 dB up to 100 kHz - critical for mixed-signal sensor front-ends and multi-channel data acquisition.
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 bandwidths up to ~500 kHz in gain-of-10 configurations for sensor signal amplification. |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures faithful reproduction of 100-kHz, 1-Vpp signals without slew-induced distortion. |
| Input Offset Voltage | ≤5.5 mV max over –40°C to 125°C - minimizes DC error in precision transducer interfaces and low-level analog front-ends. |
| Rail-to-Rail Output | Swings to within 100 mV of VCC+ and GND at 2 kΩ load - maximizes dynamic range in single-supply systems with limited headroom. |
| Quiescent Current | 1.3 mA max over temperature - allows four-channel amplification in battery-operated devices with <5 μA/channel standby overhead. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive modules, industrial PLC I/O, and extended-range environmental monitoring. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected), JEDEC MO-153 compliant - compatible with standard reflow profiles and automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier 1 output | Drives external load; rail-to-rail swing supports full-scale ADC input buffering. |
| 1IN− | Amplifier 1 inverting input | Accepts feedback network; high CMRR (>70 dB) rejects supply noise in single-ended configurations. |
| 1IN+ | Amplifier 1 non-inverting input | Connects to sensor or reference; input bias current <150 nA minimizes leakage errors in high-Z sources. |
| VCC+ | Positive supply rail | Single 2.5–5.5 V supply powers all four amplifiers; no separate VCC− required in single-supply mode. |
| 2IN+ | Amplifier 2 non-inverting input | Independent channel input; identical specs to Channel 1 enable matched multi-channel signal paths. |
| 2IN− | Amplifier 2 inverting input | Supports differential-to-single-ended conversion with matched gain-setting resistors. |
| 2OUT | Amplifier 2 output | Provides second buffered output; 135 dB inter-channel isolation prevents crosstalk in multi-sensor systems. |
| 4OUT | Amplifier 4 output | Final channel output; same drive capability (±20 mA) as other channels for active filtering or level-shifting. |
| 4IN− | Amplifier 4 inverting input | Enables unity-gain inverter configuration; stable with capacitive loads up to 22 pF per datasheet. |
| 4IN+ | Amplifier 4 non-inverting input | Accepts reference or signal source; common-mode range includes ground for true single-supply operation. |
| GND/VCC− | Ground / negative supply | Reference node for all amplifiers; ties to PCB ground plane to minimize noise coupling in mixed-signal layouts. |
| 3IN+ | Amplifier 3 non-inverting input | Third channel input; supports simultaneous processing of multiple sensor outputs without external multiplexing. |
| 3IN− | Amplifier 3 inverting input | Configurable for gain or filtering; low input offset ensures matched DC response across all four channels. |
| 3OUT | Amplifier 3 output | Third independent output; rail-to-rail swing preserves signal integrity when driving SAR ADC reference buffers. |
Key Features
| Feature | Design Value |
|---|---|
| No Crossover Distortion | Eliminates switching artifacts in audio and sensor signal paths, ensuring clean zero-crossing behavior in unity-gain followers. |
| Rail-to-Rail Output Swing | Delivers >98% of full supply range at 2 kΩ load - maximizes SNR in 12-bit+ ADC interfaces without external level-shifting. |
| Low Supply Current | 1 mA typ at 5 V for all four amplifiers - enables always-on sensor monitoring in energy-harvesting and IoT edge nodes. |
| High CMRR & PSRR | ≥70 dB over 100 kHz - rejects ripple from shared DC-DC converters and EMI in compact industrial control modules. |
| Wide Input Common-Mode Range | Extends to GND and within 0.3 V of VCC+ - supports direct connection to thermocouples, bridge sensors, and current-sense resistors. |

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 but rated for –40°C to 85°C; SOIC-14 package (larger footprint, no thermal pad). | Preferred for commercial-grade consumer electronics where extended temperature is not required. | Select LMV824DR if board space permits larger SOIC and ambient temperature stays below 85°C. |
| TLV2464IPW | Higher supply current (1.8 mA typ), lower GBW (6.4 MHz), wider VCC range (2.7–6 V); also TSSOP-14. | Better DC precision (0.6 mV VIO) but higher power - suited for precision instrumentation over speed-critical apps. | Choose TLV2464IPW when ultra-low offset dominates over power budget; verify layout compatibility with same PW footprint. |
Compared with LMV824DR and TLV2464IPW, the LMV824IPWG4 uniquely balances extended temperature operation (–40°C to 125°C), low quiescent current (1.3 mA max), and TSSOP-14 thermal performance - making it optimal for automotive and industrial edge nodes where reliability and density are co-constrained.

FAQ
What is the maximum operating temperature range for the LMV824IPWG4?
The LMV824IPWG4 is specified for continuous operation from –40°C to 125°C, making it suitable for under-hood automotive modules, industrial control cabinets, and outdoor environmental monitoring equipment where ambient temperatures exceed standard commercial limits. This rating is confirmed in the "Recommended Operating Conditions" table of the official TI SLOS434I datasheet.
Does the LMV824IPWG4 support true single-supply operation with inputs referenced to ground?
Yes, the LMV824IPWG4 features an input common-mode voltage range that includes ground (VICR extends to –0.3 V at 2.7 V supply), enabling direct connection of sensors like thermistors and bridge circuits without level-shifting circuitry. Its rail-to-rail output further ensures full dynamic range utilization in single-supply systems.
What is the typical supply current consumption of the LMV824IPWG4 at 3.3 V?
At 3.3 V supply and 25°C, the LMV824IPWG4 draws approximately 0.85 mA typical supply current (ICC) for all four amplifiers combined - extrapolated from the 5 V (1.0 mA typ) and 2.7 V (0.72 mA typ) data points in the TI SLOS434I datasheet. This value remains ≤1.3 mA across the full –40°C to 125°C range.
Can the LMV824IPWG4 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes, the LMV824IPWG4 delivers rail-to-rail output swing into 600 Ω loads: at 5 V supply, it achieves ≥4.75 V high-level and ≤0.3 V low-level output (per 5-V Electrical Characteristics table). However, output voltage compliance degrades slightly compared to 2 kΩ loading - design margins should account for this in precision applications.
Is the LMV824IPWG4 pin-compatible with other TSSOP-14 quad op-amps like the TLV2464IPW?
Yes, the LMV824IPWG4 uses the standard TSSOP-14 pinout defined in TI's PW package drawing, matching TLV2464IPW, OPA4340UA, and other industry-standard quad op-amps in the same footprint. Pin functions (e.g., 1OUT, 1IN−, VCC+, GND) align exactly - enabling drop-in replacement where electrical specs permit.
