Product details
Overview
LMV824PWR 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 monitoring front-ends.
For engineers reviewing the LMV824PWR datasheet, LMV824PWR pinout, LMV824PWR application, or LMV824PWR equivalent, this page provides verified technical context, validated pin functionality, real-world use cases with design impact, and two confirmed alternative parts with documented functional trade-offs for industrial and consumer-grade analog signal chains.
Technical Context
The LMV824PWR integrates four independent high-fidelity op-amps on a single die, each featuring rail-to-rail output swing (within 17 mV of VCC+ and 100 mV of GND at 5 V/2 kΩ), no crossover distortion, and input common-mode range extending to ground. Its architecture supports stable unity-gain operation with 64.2° phase margin at 5 V and 600 Ω load.
It operates across –40°C to 85°C (standard grade) or –40°C to 125°C (I-grade variants), with CMRR ≥70 dB and PSRR ≥75 dB over full temperature range. Amplifier-to-amplifier isolation exceeds 135 dB, making it suitable for multi-channel sensor signal conditioning 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 domains 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, 1-Vpp sine wave reproduction with <1% distortion. |
| Input Offset Voltage | 1 mV typ (25°C), 4 mV max (–40°C to 85°C) - ensures ≤10 mV error in 10× gain instrumentation stages. |
| Output Swing (RL = 2 kΩ) | 0.1 V to 4.9 V at 5 V supply - delivers true rail-to-rail dynamic range for ADC driver and reference buffer roles. |
| Supply Current (per amp) | 250 μA typ at 5 V - allows four-channel amplification with only 1 mA total quiescent draw. |
| Input Bias Current | 40 nA typ at 25°C - minimizes voltage error across high-impedance sensor sources (e.g., pH electrodes, thermistors). |
Pinout & Package
TSSOP-14 package (PW) with 0.65 mm pitch, 5.0 mm × 4.4 mm footprint, and exposed thermal pad (not electrically connected). Designed for automated assembly and moderate power dissipation (θJA = 113°C/W).
| 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 capability. |
| 1IN− | Amplifier 1 inverting input | Accepts feedback network or differential signal; common-mode range includes ground. |
| 1IN+ | Amplifier 1 non-inverting input | Accepts sensor signal or reference; matched to 1IN− for low offset drift. |
| VCC+ | Positive supply rail | Single-supply operation only; no negative rail required (GND serves as VCC−). |

| 4IN+ | Amplifier 4 non-inverting input | Enables simultaneous 4-channel signal conditioning without inter-channel coupling penalties. |
| GND/VCC− | Ground / negative supply terminal | Single-supply reference node; must be low-impedance plane to maintain PSRR and noise performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2464IDR | Higher supply current (1.4 mA typ), lower GBW (6.4 MHz), wider input voltage range (to VCC+), but no guaranteed rail-to-rail input. | Better for mixed-signal systems needing input beyond rails; less optimal for ultra-low-power battery designs. | Choose TLV2464IDR when input common-mode range exceeding supply rails is required, and 400 μA extra quiescent current is acceptable. |
| LMV324DR | Lower GBW (1 MHz), slower slew rate (1 V/μs), higher input offset (7 mV max), but lower cost and pin-compatible SOIC-14 footprint. | Targeted at cost-sensitive, non-precision applications like basic comparators or slow control loops. | Choose LMV324DR only for non-critical DC amplification where bandwidth and offset are not design constraints. |
Compared with TLV2464IDR and LMV324DR, the LMV824PWR uniquely balances 5.5 MHz bandwidth, rail-to-rail output, and sub-1 mA supply current in a TSSOP-14 package - making it the only option among the three qualified for precision, low-power, space-constrained analog front-ends.

FAQ
What is the operating temperature range for the LMV824PWR?
The LMV824PWR is rated for operation from –40°C to +85°C. This standard temperature grade is specified in the official Texas Instruments datasheet SLOS434I and applies to all LMV824 variants in PW, D, and DGV packages unless marked with an 'I' suffix (e.g., LMV824IPWR), which extends the range to –40°C to +125°C.
Does the LMV824PWR support true rail-to-rail input?
No, the LMV824PWR features rail-to-rail *output* swing but does not support rail-to-rail *input*. Its input common-mode voltage range extends to ground (VCC−) but only up to VCC+ – 0.2 V at 25°C, as confirmed in the "Common-mode input voltage range" parameter table of the LMV824 datasheet.
Can the LMV824PWR drive a 600 Ω load effectively?
Yes, the LMV824PWR can source and sink up to 20 mA (typical) at 5 V supply, supporting 600 Ω loads with output swing of 0.17 V to 4.84 V. The datasheet specifies output voltage swing under RL = 600 Ω conditions, confirming its suitability for line-driver and DAC-buffer applications.
Is the LMV824PWR pin-compatible with other quad op-amps in TSSOP-14?
The LMV824PWR uses a standard TSSOP-14 pinout defined by Texas Instruments for the LMV824 family. It is not pin-compatible with generic quad op-amps like the LM324 or TL074 due to differing pin assignments (e.g., dedicated VCC+/GND placement and channel ordering). Always verify pin mapping against the LMV824-specific top-view diagram before PCB layout.
What is the typical input offset voltage drift over temperature for the LMV824PWR?
The LMV824PWR has an average input offset voltage temperature coefficient (αVIO) of 1 μV/°C, as specified in the 2.7-V and 5-V electrical characteristics tables. This low drift ensures minimal offset change across its –40°C to +85°C operating range, supporting stable DC-coupled gain stages in precision measurement systems using the LMV824PWR.
