Texas Instruments LMV824IPWRG4

Overview

LMV824IPWRG4 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 battery-powered sensors and medical instrumentation.

For engineers reviewing the LMV824IPWRG4 datasheet, LMV824IPWRG4 pinout, LMV824IPWRG4 application, or LMV824IPWRG4 equivalent, key selection considerations include its –40°C to 125°C operating range, TSSOP-14 package footprint, rail-to-rail output swing down to 100 mV from rails (at 2 kΩ load), and compatibility with single-supply systems requiring high CMRR (≥70 dB) and low input offset voltage (≤3.5 mV).

Technical Context

The LMV824IPWRG4 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 both supply rails. Its internal architecture eliminates crossover distortion and supports stable unity-gain operation with 64.2° phase margin at 5 V and 600 Ω load.

Each amplifier features matched AC performance: 5.5 MHz GBW, 1.9 V/μs slew rate, 135 dB amplifier-to-amplifier isolation, and 42 nV/√Hz input voltage noise at 1 kHz - making it suitable for multi-channel analog front-ends where channel crosstalk and dynamic range are critical.

FAQ

What is the maximum operating temperature for the LMV824IPWRG4?

The LMV824IPWRG4 is characterized for continuous operation from –40°C to +125°C. This extended temperature grade is confirmed in the device's ordering information table and electrical characteristics sections for LMV8xxI variants, distinguishing it from the standard LMV824 (–40°C to 85°C). All key parameters - including input offset voltage, supply current, and output swing - are guaranteed across this full range.

Does the LMV824IPWRG4 support true single-supply operation with inputs referenced to ground?

Yes, the LMV824IPWRG4 supports true single-supply operation: its input common-mode voltage range extends from 0.3 V below GND to 4.3 V above GND at 5 V supply (VICR = –0.3 V to 4.3 V), and its rail-to-rail output swings within 100 mV of both rails. This allows direct interfacing with ground-referenced sensors (e.g., thermistors, bridge transducers) without level-shifting circuitry.

What is the recommended power supply decoupling for the LMV824IPWRG4?

TI recommends placing a 0.1 μF ceramic capacitor between Pin 4 (VCC+) and Pin 8 (GND/VCC−), located as close as possible to the TSSOP-14 package. For systems with multiple LMV824IPWRG4 units or noisy supplies, add a bulk 4.7 μF tantalum or aluminum electrolytic capacitor at the board-level VCC net. The device's PSRR (≥70 dB) helps suppress supply ripple, but local high-frequency decoupling remains essential for stability.

Can the LMV824IPWRG4 drive a 600 Ω load while maintaining rail-to-rail output swing?

Yes - the LMV824IPWRG4 can source/sink up to 26 mA per amplifier (VO = 0 V or 5 V), enabling full rail-to-rail swing into 600 Ω loads at 5 V supply. At 25°C, output swing is specified as 0.17–0.25 V (low) and 4.75–4.84 V (high) into 600 Ω, meeting rail-to-rail expectations for most precision applications. Performance is validated across the full –40°C to 125°C range.

Is the LMV824IPWRG4 pin-compatible with other quad op-amps in the LMV8xx family?

Yes - the LMV824IPWRG4 shares identical pinout and functionality with all LMV824 variants in TSSOP-14 (PW) and TVSOP-14 (DGV) packages, including LMV824PWR, LMV824DGVR, and LMV824IDGVR. Pin assignments match the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram in the datasheet, ensuring drop-in replacement within the same package type and temperature grade.
