Product details
Overview
PLPV801DBVT from Texas Instruments is a single-channel nanopower operational amplifier designed for ultra-low-power sensing in battery-operated gas detectors, PIR motion sensors, and IoT remote nodes. It delivers 320 nA typical supply current per channel, 3.5 mV maximum offset voltage, 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 over –40°C to 125°C.
For engineers reviewing the PLPV801DBVT datasheet, PLPV801DBVT pinout, PLPV801DBVT application, or PLPV801DBVT equivalent, this page provides verified technical context, real-world design meaning for key specs, validated pin functions, application-specific implementation insights, and two confirmed alternative parts with documented functional and application differences.
Technical Context
The PLPV801DBVT employs a CMOS input stage with ≤100 fA typical input bias current and supports negative-rail sensing - its common-mode input range extends to V–, enabling true single-supply operation in low-voltage sensor front-ends. Its unity-gain stable architecture achieves 8 kHz gain-bandwidth product while maintaining 120 dB open-loop gain and ≥77 dB CMRR at 5 V supply.
EMI protection is integrated to suppress interference from mobile phones, WiFi, and RFID readers. The device features no output reversals under common-mode transients and maintains rail-to-rail output capability across temperature and supply voltage (1.6–5.5 V), critical for preserving dynamic range in energy-constrained systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 450 nA typical per channel - enables >10-year battery life in CO detectors with coin-cell power. |
| Offset Voltage | 3.5 mV max - ensures sub-ppm resolution in electrochemical gas sensors without trimming. |
| Input Bias Current | ≤100 fA typical - eliminates leakage-induced errors in high-impedance pH or ion-selective electrode interfaces. |
| Gain-Bandwidth | 8 kHz - sufficient for DC–10 Hz sensor signal conditioning (e.g., smoke alarm ionization current) while minimizing power. |
| Rail-to-Rail Output | Swings to within 3.5 mV of V+ and V– at 1.8 V/100 kΩ - maximizes ADC utilization in 1.8 V microcontroller systems. |
| Common-Mode Range | Extends to V– - allows direct connection to grounded sensor electrodes without level-shifting circuitry. |
| Temperature Range | –40°C to 125°C - qualified for thermostats, automotive cabin air quality monitors, and industrial environmental sensors. |
Pinout & Package
PLPV801DBVT is packaged in a 5-pin SOT-23 (DBV) with body size 2.90 mm × 1.60 mm, optimized for space-constrained PCB layouts in portable medical and wireless sensor nodes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Output | Amplified differential signal; drives high-impedance loads (≥10 MΩ) directly into ADC inputs or filter networks. |
| 2 - V– | Negative Power Supply | Ground reference for single-supply operation; common return for sensor bias and signal chain. |
| 3 - +IN | Non-Inverting Input | High-impedance node for reference voltage or sensor electrode connection; accepts signals down to V–. |
| 4 - –IN | Inverting Input | Feedback node in transimpedance or difference amplifier configurations; matched to +IN for low offset. |
| 5 - V+ | Positive Power Supply | 1.6–5.5 V input; powers internal CMOS core and rail-to-rail output stage with minimal quiescent draw. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV811DBVT | 370 µV max offset voltage (vs. 3.5 mV); 450 nA typical IQ; same SOT-23-5 package. | Better DC accuracy for precision thermistor or RTD interfaces; higher cost and lower availability than LPV801DBVT. | Select LPV811DBVT when offset drift <0.5 µV/°C is required and budget permits premium grade. |
| TLV8811IDBVR | 150 nA typical IQ (lower); 4.5 mV max offset; 6 kHz GBW; same SOT-23-5 footprint. | Ultra-low IQ suits energy-harvesting nodes; reduced bandwidth limits use in fast transient gas sensors. | Choose TLV8811IDBVR only for sub-100 nA average system current targets where 8 kHz bandwidth is unnecessary. |
Compared with LPV801DBVT, LPV811DBVT offers 10× lower offset for precision analog front-ends but trades higher cost and identical IQ, while TLV8811IDBVR reduces IQ by ~33% at the expense of bandwidth and offset - making PLPV801DBVT the optimal balance of nanopower, accuracy, and responsiveness for mainstream battery-powered sensors.

FAQ
What is the maximum operating temperature for PLPV801DBVT?
The PLPV801DBVT is specified for continuous operation from –40°C to +125°C ambient temperature. This extended range supports deployment in automotive cabin air quality modules, industrial thermostat housings, and outdoor environmental sensor enclosures where thermal extremes occur. The device maintains 3.5 mV max offset and 8 kHz bandwidth across this full range, as validated in TI's SNOSCZ3B datasheet Section 6.3.
Does PLPV801DBVT support rail-to-rail input operation?
PLPV801DBVT supports rail-to-rail *output*, but its input common-mode range extends only to V– and up to (V+) – 0.9 V - not full rail-to-rail input. This negative-rail sensing capability enables direct connection to grounded sensor electrodes, but inputs must stay ≥0.9 V below V+ to maintain specified offset and CMRR. For true rail-to-rail input, consider TI's OPA316 or similar alternatives.
Can PLPV801DBVT drive capacitive loads directly?
No - PLPV801DBVT is unity-gain stable but sensitive to capacitive loading. Driving >50 pF directly risks peaking or oscillation due to phase lag. TI recommends inserting a 30–50 kΩ isolation resistor (RISO) between the output and capacitive load (e.g., ADC input capacitance or long traces). This preserves stability while limiting output swing reduction, as detailed in Section 7.4.4 of the PLPV801DBVT datasheet.
What is the typical input bias current of PLPV801DBVT?
The PLPV801DBVT exhibits ≤100 fA typical input bias current at 25°C and 1.8 V supply, with values remaining below 1 pA across –40°C to 125°C. This ultra-low leakage is critical for interfacing with high-impedance sources like electrochemical gas sensors, pH electrodes, or pyroelectric elements where even picoampere errors corrupt signal integrity.
Is PLPV801DBVT pin-compatible with other SOT-23 op-amps?
PLPV801DBVT uses the industry-standard 5-pin SOT-23 (DBV) pinout: Pin 1 = OUT, Pin 2 = V–, Pin 3 = +IN, Pin 4 = –IN, Pin 5 = V+. It is pin-compatible with TI's LPV811DBVT and generic single-op-amp SOT-23 footprints, but not with dual-amplifier or different-function SOT-23 variants (e.g., comparators or voltage references) that share the same package outline but differ in pin assignment.
