Product details
Overview
LMV824IPW 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, 1 mA typical supply current at 5 V, and rail-to-rail output swing - enabling precision signal conditioning in space-constrained portable electronics such as medical sensors and battery-powered instrumentation.
For engineers reviewing the LMV824IPW datasheet, LMV824IPW pinout, LMV824IPW application, or LMV824IPW equivalent, key selection considerations include its –40°C to 125°C operating range, TSSOP-14 package footprint, quad-channel integration for multi-sensor front-ends, and compatibility with single-supply systems requiring ground-referenced input common-mode range.
Technical Context
The LMV824IPW implements a CMOS-input, rail-to-rail output op-amp architecture with no crossover distortion, supporting single-supply operation down to 2.5 V. Its input stage includes ESD protection and operates with a common-mode voltage range extending to ground (–0.2 V at 5 V), while the output can swing within 17 mV of VCC+ and 100 mV of GND under 2 kΩ load.
It features 135 dB amplifier-to-amplifier isolation and 42 nV/√Hz input voltage noise at 1 kHz, making it suitable for multi-channel analog signal chains where crosstalk and noise coupling must be minimized - such as in data acquisition modules and sensor fusion subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion battery rails or 3.3 V/5 V system supplies without regulation. |
| Gain Bandwidth Product | 5.5 MHz typ at 5 V - enables stable closed-loop operation up to ~500 kHz with unity-gain stability into 22 pF capacitive loads. |
| Slew Rate | 1.9 V/μs typ at 5 V - sufficient for 10-bit ADC driving and moderate-speed sensor signal amplification without distortion. |
| Input Offset Voltage | 1 mV typ, 5.5 mV max over –40°C to 125°C - ensures <1 LSB error in 10-bit systems with 5 V full-scale range. |
| Output Swing | Within 17 mV of VCC+ and 100 mV of GND at 2 kΩ load - preserves dynamic range in single-supply configurations with ground-referenced inputs. |
| Supply Current per Channel | 0.25 mA typ at 5 V - allows four independent amplifiers to operate continuously on <1 mA total, critical for always-on sensor nodes. |
| Common-Mode Input Range | Extends to –0.2 V below GND and up to 4.3 V at 5 V supply - accommodates inputs referenced to ground or biased near supply rails. |
Pinout & Package
TSSOP-14 package (PW), 5.0 mm × 4.4 mm body, 0.65 mm pitch, exposed thermal pad optional - designed for high-density PCB layouts with improved thermal dissipation vs. SOIC-14.
| 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 | Differential input node; accepts signals within –0.2 V to 4.3 V at 5 V supply. |
| 1IN+ | Amplifier 1 non-inverting input | Differential input node; matched bias current and offset performance with 1IN−. |
| VCC+ | Positive supply rail | Primary power connection; supports 2.5–5.5 V; decoupling capacitor required within 1 cm. |
| 2IN+ | Amplifier 2 non-inverting input | Independent input for second channel; electrically isolated from other amplifiers (135 dB rejection). |
| 2IN− | Amplifier 2 inverting input | Paired with 2IN+; identical electrical specs to 1IN−/1IN+. |
| 2OUT | Amplifier 2 output | Independent output; shares same output drive strength and swing limits as 1OUT. |

| 4IN− | Amplifier 4 inverting input | Rightmost input pair; layout symmetry aids matching in differential sensor interfaces. |
| 4IN+ | Amplifier 4 non-inverting input | Complements 4IN−; used for fourth sensor channel or reference buffer. |
| GND/VCC− | Ground / negative supply | Single-ended ground reference; also serves as negative rail in dual-supply mode (±2.5 V max). |
| 3IN+ | Amplifier 3 non-inverting input | Third channel input; positioned between power pins to reduce supply-induced crosstalk. |
| 3IN− | Amplifier 3 inverting input | Matches 3IN+; supports fully differential configuration with external resistor network. |
| 3OUT | Amplifier 3 output | Third output; enables simultaneous processing of three independent analog signals (e.g., tri-axis sensor). |
Key Features
| Feature | Design Value |
|---|---|

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 | SOIC-14 package; rated for –40°C to 85°C only; identical electrical specs and pinout. | Not qualified for under-hood or extended-temperature industrial use; lower thermal resistance than TSSOP but larger footprint. | Select when board space permits and extended temperature is not required; drop-in replacement for prototyping. |
| TLV9064IPWR | Higher GBW (10 MHz), lower input offset (0.3 mV typ), but higher supply current (0.53 mA per channel); same TSSOP-14 package. | Better suited for active filter design and higher-resolution ADC drivers; less optimal for ultra-low-power always-on monitoring. | Choose when bandwidth or DC accuracy outweighs quiescent current constraints - e.g., in high-speed data loggers. |
Compared with LMV824DR, the LMV824IPW offers extended temperature qualification and smaller PCB area; compared with TLV9064IPWR, it trades bandwidth and offset for 60% lower supply current - making LMV824IPW optimal for thermally constrained, battery-sensitive designs requiring robustness over speed.

FAQ
What is the operating temperature range of the LMV824IPW?
The LMV824IPW is characterized for operation from –40°C to +125°C, making it suitable for automotive cabin modules, industrial motor control environments, and outdoor sensor deployments where ambient temperatures exceed standard commercial-grade limits. This extended range is confirmed in TI's SLOS434I datasheet Section "Recommended Operating Conditions" and applies specifically to the 'I' grade (LMV824I) variants including LMV824IPW.
Does the LMV824IPW support true rail-to-rail input operation?
The LMV824IPW does not provide rail-to-rail input common-mode range - its input stage operates from –0.2 V below GND to 4.3 V at 5 V supply (VICR = –0.2 V to 4.3 V). However, it does offer rail-to-rail output swing, reaching within 17 mV of VCC+ and 100 mV of GND under 2 kΩ load. This asymmetry is explicitly documented in the "Electrical Characteristics" tables for LMV824I at 5 V.
What is the maximum capacitive load the LMV824IPW can drive stably?
The LMV824IPW maintains stability with up to 22 pF capacitive load when configured for 40-dB closed-loop DC gain, as verified in the "Gain and Phase Margin vs Frequency" plots (Figures 17–21) of the SLOS434I datasheet. Driving larger loads requires external isolation resistors (e.g., 10–100 Ω in series with the output) to preserve phase margin above 60°.
Is the LMV824IPW pin-compatible with other packages in the LMV824 family?
Yes - the LMV824IPW (TSSOP-14) shares identical pinout and electrical functionality with LMV824D (SOIC-14), LMV824DR (SOIC-14 tape-and-reel), and LMV824DGVR (TVSOP-14). All variants use the same 14-pin assignment shown in the "LMV824 . . . D, DGV, OR PW PACKAGE (TOP VIEW)" diagram on page 1 of the datasheet.
What is the typical supply current consumption of the LMV824IPW at 3.3 V?
While the datasheet specifies ICC = 1 mA typ at 5 V and 0.72 mA typ at 2.7 V for the LMV824 (non-I grade), the LMV824IPW (I grade) shows 1 mA typ at 5 V and 0.72 mA typ at 2.7 V in Table "LMV824 (all four amplifiers)" under "5-V Electrical Characteristics". Interpolating linearly, typical supply current at 3.3 V is approximately 0.85 mA - consistent with measured curves in Figure 3 ("Supply Current vs Supply Voltage") for the LMV824 family.
