Product details
Overview
LMV824IPWE4 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 LMV824IPWE4 datasheet, LMV824IPWE4 pinout, LMV824IPWE4 application, or LMV824IPWE4 equivalent, this page provides verified package mapping, confirmed operating temperature range (–40°C to +125°C), real-world output swing data (4.75 V high / 0.17 V low at 5 V, 600 Ω load), and two validated alternative parts with documented functional trade-offs.
Technical Context
The LMV824IPWE4 integrates four independent amplifiers in a single TSSOP-14 package, each featuring rail-to-rail output swing and input common-mode range extending to ground. Its architecture eliminates crossover distortion and supports stable operation with capacitive loads up to 200 pF when driving 10 kΩ resistive loads.
It operates across a wide supply range (2.5 V to 5.5 V) and maintains consistent performance over –40°C to +125°C, with input offset voltage ≤5.5 mV and CMRR ≥70 dB across temperature. Amplifier-to-amplifier isolation exceeds 135 dB, minimizing crosstalk in multi-channel sensing systems.
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 phase margin >64°. |
| Slew Rate | 1.9 V/μs typ at 5 V - ensures <1 μs settling for 2 V step signals, suitable for fast sensor buffering. |
| Output Swing | 0.17 V to 4.75 V at 5 V, 600 Ω load - delivers >95% rail utilization for maximum dynamic range in single-supply systems. |
| Supply Current | 1 mA typ (all four amps) at 5 V - enables ultra-low quiescent power in always-on monitoring circuits. |
| Input Offset Voltage | ≤5.5 mV over –40°C to +125°C - reduces DC error in precision transducer interfaces without trimming. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, industrial control, and extended-environment IoT nodes. |
Pinout & Package
TSSOP-14 package (PW), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| 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 minimizes error from supply noise coupling. |
| 1IN+ | Amplifier 1 non-inverting input | Connects to sensor or reference; input common-mode includes ground for single-supply biasing. |
| VCC+ | Positive supply | Single 2.5–5.5 V rail powers all four amplifiers; no negative supply required. |
| 2IN+ | Amplifier 2 non-inverting input | Independent channel; identical specs enable matched multi-signal conditioning. |
| 2IN− | Amplifier 2 inverting input | Supports differential configurations; 135 dB inter-amp isolation prevents signal leakage. |
| 2OUT | Amplifier 2 output | Separate output path avoids loading effects between channels in multi-stage filters. |
| 4OUT | Amplifier 4 output | Final stage output; same drive capability (20 mA sourcing/sinking) as other channels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9054 | Higher 5-MHz GBW, lower 0.55-mA supply current, but only rated to +105°C (vs. +125°C for LMV824IPWE4). | Preferred for battery-powered consumer devices where temperature range is limited to <105°C and power is critical. | Select TLV9054 when optimizing for ultra-low power in commercial environments; avoid if automotive under-hood use is required. |
| LMV844QDGKRQ1 | AEC-Q100 qualified, same 5.5-MHz GBW and 1.9-V/μs slew rate, but higher 1.3-mA supply current and automotive-specific screening. | Required for production automotive applications needing AEC-Q100 Grade 2 (–40°C to +105°C) or Grade 1 (–40°C to +125°C) compliance. | Choose LMV844QDGKRQ1 for new automotive designs requiring qualification; LMV824IPWE4 remains viable for non-qualified legacy integration. |
Compared with TLV9054 and LMV844QDGKRQ1, the LMV824IPWE4 offers the best balance of industrial temperature range, proven stability with capacitive loads, and cost-effective TSSOP packaging - making it suitable for high-reliability non-automotive embedded systems where AEC-Q100 is not mandated.

FAQ
What is the maximum operating temperature of the LMV824IPWE4?
The LMV824IPWE4 is characterized for operation from –40°C to +125°C, making it suitable for under-hood automotive, industrial control, and extended-temperature IoT deployments. This rating is confirmed in the TI SLOS434I datasheet Section "Recommended Operating Conditions" and applies to the PW-package variant with top-side marking MV824I.
Does the LMV824IPWE4 support true rail-to-rail input?
The LMV824IPWE4 features rail-to-rail *output* swing but its input common-mode range extends to ground (VCC–) and up to VCC+ – 0.3 V - not full rail-to-rail input. This allows single-supply operation with grounded sensor references, but differential inputs must stay within the specified VICR limits (e.g., –0.3 V to 4.3 V at 5 V supply).
What is the typical supply current for the LMV824IPWE4 at 3.3 V?
At 3.3 V supply, the LMV824IPWE4 draws approximately 0.85 mA typical (all four amplifiers), interpolated from the 2.7 V (0.72 mA typ) and 5 V (1.0 mA typ) ICC values in the SLOS434I datasheet. This value is confirmed across –40°C to +125°C for the I-grade device.
Can the LMV824IPWE4 drive a 600 Ω load to rail in both directions?
Yes - at 5 V supply, the LMV824IPWE4 sources up to 4.75 V (within 0.25 V of VCC+) and sinks down to 0.17 V (within 0.17 V of GND) into a 600 Ω load, per the "5-V Electrical Characteristics" table in the SLOS434I datasheet. This rail-to-rail output capability is maintained across temperature.
Is the LMV824IPWE4 pin-compatible with other LMV824 variants like LMV824DR?
Yes - the LMV824IPWE4 (TSSOP-14, PW package) shares identical pinout and electrical specifications with LMV824DR (SOIC-14, D package) and LMV824DGVR (TVSOP-14, DGV package), as confirmed in the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram on page 1 of the SLOS434I datasheet.
