Product details
Overview
LMV821IDBVRE4 from Texas Instruments is a single-channel, 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 0.3 mA typical supply current at 5 V - enabling precision signal conditioning in space-constrained portable electronics such as sensor front-ends and battery-powered instrumentation.
For engineers reviewing the LMV821IDBVRE4 datasheet, LMV821IDBVRE4 pinout, LMV821IDBVRE4 application, or LMV821IDBVRE4 equivalent, key selection criteria include its –40°C to 125°C operating range, SOT-23-5 package footprint, rail-to-rail output swing (4.75 V high / 0.17 V low at 5 V, RL = 600 Ω), input offset voltage ≤3.5 mV, and absence of crossover distortion.
Technical Context
The LMV821IDBVRE4 employs a CMOS input stage with rail-to-rail output stage, supporting true single-supply operation down to 2.5 V while maintaining stable phase margin (64.2°) and gain margin (8.7 dB) under 5 V, 600 Ω load conditions. Its input common-mode range extends from VCC– (GND) to within 0.3 V of VCC+, and it achieves 72 dB CMRR and 75 dB PSRR at 5 V.
This device belongs to the LMV8xxI temperature-grade family, characterized across –40°C to 125°C, and is electrically compatible with the LMV3xx series but offers higher bandwidth and faster slew rate - making it suitable for higher-speed analog signal paths where thermal robustness and low quiescent power are critical.
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 rails without level shifting. |
| Gain Bandwidth | 5.5 MHz typ at 5 V - supports closed-loop amplification up to ~500 kHz with unity-gain stability into 22 pF capacitive loads. |
| Slew Rate | 1.9 V/μs typ at 5 V - allows clean reproduction of 300-kHz full-scale sine waves without slew-induced distortion. |
| Output Swing | Rail-to-rail: 0.17 V above GND / 4.75 V below VCC+ at 5 V, RL = 600 Ω - maximizes dynamic range in single-supply data acquisition. |
| Input Offset Voltage | ≤3.5 mV max (25°C), ≤5.5 mV max (–40°C to 125°C) - ensures <0.1% error in 12-bit ADC driver applications at mid-scale. |
| Supply Current | 0.3 mA typ at 5 V - permits integration into always-on sensor nodes with sub-μA sleep-state budgets. |
| Operating Temp | –40°C to 125°C - qualified for under-hood automotive, industrial motor control, and harsh-environment IoT edge nodes. |
Pinout & Package
SOT-23-5 package (DBV) with 1.6 mm × 2.9 mm footprint and 0.95 mm height - compatible with standard pick-and-place equipment and reflow profiles per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Amplifier output | Delivers rail-to-rail voltage swing; drives 600 Ω loads with <0.25 V headroom at 5 V supply. |
| 2 (IN−) | Inverting input | High-impedance CMOS node; supports input common-mode range from GND to VCC+ − 0.3 V. |
| 3 (GND/VCC−) | Ground / negative supply | Single-supply reference point; must be low-impedance to minimize noise coupling and PSRR degradation. |
| 4 (IN+) | Non-inverting input | Matches IN− in bias current (≤30 nA) and offset; enables precision differential sensing with matched external resistors. |
| 5 (VCC+) | Positive supply | Accepts 2.5–5.5 V; internal regulation ensures consistent performance across supply variation and load transients. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV821DBVR | Same electrical specs but rated for –40°C to 85°C; SOT-23-5 package identical. | Limited to commercial/industrial ambient environments; not qualified for under-hood or extended-temperature industrial use. | Select when cost sensitivity outweighs extended temperature requirement and thermal derating is acceptable. |
| TLV9001IDBVR | Lower 0.17 mA supply current, 1 MHz GBW, rail-to-rail I/O, but only 0.5 mV max VIO at 25°C. | Better suited for ultra-low-power, lower-bandwidth sensor buffering where precision offset is critical and speed is secondary. | Choose when <0.5 mV offset and sub-200 μA supply current are mandatory, and 1 MHz bandwidth suffices. |
Compared with LMV821DBVR, LMV821IDBVRE4 provides guaranteed 125°C operation essential for automotive and industrial deployments; versus TLV9001IDBVR, it trades 0.13 mA higher supply current for +4.5 MHz bandwidth and higher output drive strength - prioritizing speed and thermal resilience over minimal quiescent power.

FAQ
What is the maximum operating temperature for LMV821IDBVRE4?
The LMV821IDBVRE4 is characterized for continuous operation from –40°C to +125°C. This extended temperature grade makes it suitable for under-hood automotive applications, industrial motor drives, and outdoor environmental monitoring systems where ambient temperatures exceed standard industrial limits. The device maintains specified gain bandwidth, slew rate, and input offset voltage across this full range.
Does LMV821IDBVRE4 support true rail-to-rail output swing?
Yes, LMV821IDBVRE4 provides rail-to-rail output swing: at VCC+ = 5 V and RL = 600 Ω, it delivers a minimum high-level output of 4.75 V and a maximum low-level output of 0.17 V. This capability maximizes dynamic range in single-supply systems, enabling direct interface with 12-bit ADCs without level-shifting circuitry or supply headroom penalties.
What is the supply current consumption of LMV821IDBVRE4 at 3.3 V?
At VCC+ = 3.3 V and TA = 25°C, LMV821IDBVRE4 draws 0.25 mA typical supply current (ICC), based on interpolation of 2.7 V and 5 V test data from the official datasheet. This value remains within ±15% across –40°C to 125°C, supporting predictable power budgeting in battery-powered and thermally variable designs.
Is LMV821IDBVRE4 pin-compatible with other LMV8xx variants?
LMV821IDBVRE4 uses the SOT-23-5 (DBV) package and shares identical pinout with LMV821DBVR, LMV821IDBVT, and LMV821DCKR/T - all featuring OUT, IN−, GND, IN+, and VCC+ on pins 1–5 respectively. However, it is not pin-compatible with dual (LMV822) or quad (LMV824) variants, which use 8-pin and 14-pin packages with different pin assignments.
Why is LMV821IDBVRE4 marked "Not Recommended for New Designs"?
TI designated LMV821IDBVRE4 as "Not Recommended for New Designs" due to obsolescence planning - newer alternatives like TLV9001 or OPA320 offer improved offset, noise, or power efficiency. However, LMV821IDBVRE4 remains fully supported for existing production, with guaranteed supply continuity, full datasheet compliance, and no functional or reliability degradation in deployed systems.
