Product details
Overview
LPV811DBVR from Texas Instruments is a single-channel nanopower precision operational amplifier designed for ultra-low-power sensor signal conditioning in battery-critical applications. It delivers 425 nA typical supply current, 370 µV maximum offset voltage, 8 kHz gain-bandwidth, rail-to-rail output swing within 3.5 mV of rails at 1.8 V, and operates from 1.6 V to 5.5 V - enabling multi-year operation in CO gas detectors and IoT remote sensors.
For engineers reviewing the LPV811DBVR datasheet, LPV811DBVR pinout, LPV811DBVR application, or LPV811DBVR equivalent, key selection considerations include its femtoamp-level input bias current (±100 fA), –40°C to 125°C temperature range, EMI-hardened architecture, negative-rail-sensing input stage, and SOT-23-5 package compatibility with space-constrained PCB layouts.
Technical Context
The LPV811DBVR employs a CMOS input stage optimized for high-impedance sources, with common-mode input range extending to the negative rail (V–) and guaranteed CMRR ≥77 dB across –40°C to 125°C. Its internal unity-gain compensation ensures stability without external components while supporting capacitive load isolation via series RISO (30–50 kΩ recommended).
It features a rail-to-rail output stage delivering 3.5 mV headroom from V+ and 2.5 mV from V– at 1.8 V/100 kΩ, and integrates on-die EMI protection to suppress interference from mobile/WiFi/RFID sources - critical for reliable operation in noisy industrial and portable medical environments.

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV8811DBVR | Higher 650 nA supply current; 1.2 mV max offset; same SOT-23-5 package | Less suitable for sub-ppm gas sensing due to higher offset and drift | Preferred where cost sensitivity outweighs precision and battery life requirements |
| OPA316IDBVR | 100 µA supply current; 100 kHz GBW; 500 µV max offset; same footprint | Targeted at higher-speed, lower-precision applications like motor control feedback | Select when bandwidth >10 kHz is required and power budget allows >200× higher current draw |
Compared with TLV8811DBVR and OPA316IDBVR, the LPV811DBVR uniquely balances ultra-low quiescent current (450 nA), precision offset (±370 µV), and rail-to-rail operation in a miniature SOT-23-5 - making it the only viable choice for decade-long, battery-operated, sub-microvolt-signal applications such as electrochemical gas sensing and energy-harvested environmental monitoring.

FAQ
What is the maximum operating temperature for LPV811DBVR?
The LPV811DBVR is rated for continuous operation from –40°C to +125°C, meeting industrial and automotive under-hood requirements. This specification is verified per JEDEC JESD22-A108 and confirmed in the SNOSD33B datasheet Section 6.3, with thermal performance characterized up to 150°C junction temperature under short-circuit conditions.
Does LPV811DBVR support rail-to-rail input?
No, LPV811DBVR does not support rail-to-rail input. Its input common-mode voltage range extends from V– to (V+) – 0.9 V, as specified in Section 6.5 of the SNOSD33B datasheet. However, it does feature negative-rail sensing - meaning the lower bound includes V– - which enables true single-supply operation without level-shifting circuitry.
Can LPV811DBVR drive capacitive loads directly?
LPV811DBVR is unity-gain stable but becomes unstable with capacitive loads >50 pF directly on the output. As detailed in Section 7.4.4 and Figure 45 of the SNOSD33B datasheet, a 30–50 kΩ isolation resistor (RISO) must be placed between the output and capacitive load to maintain phase margin and prevent peaking or oscillation.
What is the typical input offset voltage drift of LPV811DBVR?
The LPV811DBVR has a guaranteed maximum input offset voltage drift of ±1 µV/°C over the full –40°C to +125°C temperature range, as specified in Section 6.5 (Electrical Characteristics) of the SNOSD33B datasheet. This low drift enables stable DC-coupled amplification in thermally varying environments without recalibration.
Is LPV811DBVR pin-compatible with other SOT-23-5 op-amps?
LPV811DBVR uses the industry-standard SOT-23-5 pinout (OUT, V–, +IN, –IN, V+), matching TI's TLV8811DBVR and many generic single op-amps. However, functional compatibility requires verification of supply range, offset, and quiescent current - e.g., substituting LPV811DBVR for a higher-power op-amp may require layout updates to minimize noise coupling.
