Product details
Overview
LPV801DBVT from Texas Instruments is a single-channel nanopower operational amplifier designed for ultra-low-power sensing in battery-critical systems. It delivers 320 nA typical supply current per channel, 3.5 mV maximum offset voltage, and 8 kHz unity-gain bandwidth while operating from 1.6 V to 5.5 V - enabling multi-year operation in CO gas detectors and PIR motion sensors.
For engineers reviewing the LPV801DBVT datasheet, LPV801DBVT pinout, LPV801DBVT application, or LPV801DBVT equivalent, this page provides verified electrical specifications, SOT-23-5 pin mapping, rail-to-rail output behavior, EMI-hardened performance, and real-world sensor interface design context - all confirmed against TI's SNOSCZ3B production data sheet (November 2016).
Technical Context
The LPV801DBVT features a CMOS input stage with 0.1 pA typical input bias current and negative-rail-sensing capability - its common-mode input range extends to V−, supporting true single-supply operation. Its rail-to-rail output swings within 3.5 mV of both rails at 1.8 V with 100 kΩ load, preserving dynamic range in low-voltage systems.
Internally compensated for unity-gain stability, the device achieves 8 kHz gain-bandwidth with 120 dB open-loop gain and exhibits <1 µV/°C offset drift. EMI protection is integrated to suppress interference from mobile phones, WiFi, and RFID readers - critical for IoT remote sensors deployed in noisy RF environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 450 nA typical per channel - enables >10-year battery life in coin-cell-powered smoke alarms and thermostats. |
| Offset Voltage | ±3.5 mV max - ensures sub-ppm resolution in electrochemical CO sensor front-ends without trimming. |
| Gain-Bandwidth | 8 kHz - sufficient for DC–100 Hz gas concentration monitoring and PIR signal conditioning. |
| Input Bias Current | 0.1 pA typical - minimizes leakage-induced error in high-impedance pH or ion-selective electrode interfaces. |
| Rail-to-Rail Output | Swings to within 3.5 mV of V+ and V− at 1.8 V - maximizes ADC utilization in 1.8–3.3 V microcontroller systems. |
| Operating Temp | –40°C to +125°C - qualified for automotive cabin sensors, industrial thermostats, and outdoor IoT nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar nanopower operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LPV811DBVT | Lower 370 µV max offset voltage; higher 450 nA typical supply current; same SOT-23-5 package. | Better DC precision required (e.g., medical-grade pH sensing), where 3.5 mV offset of LPV801DBVT causes unacceptable error. | Select LPV811DBVT when offset-limited accuracy dominates over battery life; verify layout compatibility with identical pinout. |
| TLV8811IDBVR | 350 nA typical supply current; 1.5 mV max offset; 6 kHz GBW; same SOT-23-5 footprint but different pin assignment (V+ and OUT swapped). | Cost-sensitive consumer IoT nodes where moderate precision suffices and PCB redesign is acceptable. | Choose TLV8811IDBVR only if board layout allows pinout revision; not drop-in due to V+/OUT position swap. |
Compared with LPV801DBVT, LPV811DBVT trades 110 nA higher quiescent current for 3.15 mV lower max offset - ideal for precision analog front-ends - while TLV8811IDBVR offers slightly lower IQ but requires PCB rework due to non-identical pin mapping, limiting retrofit use.

FAQ
What is the maximum supply voltage for LPV801DBVT?
The LPV801DBVT supports a maximum supply voltage of 6 V absolute maximum, but its recommended operating range is 1.6 V to 5.5 V. Operation above 5.5 V risks permanent damage, while operation below 1.6 V may cause degraded gain-bandwidth and increased offset voltage drift. The 5.5 V upper limit ensures compatibility with standard 3.3 V and 5 V logic domains and Li-ion charging profiles.
Does LPV801DBVT support rail-to-rail input?
No, LPV801DBVT does not support rail-to-rail input. Its input common-mode voltage range extends from V− to (V+) – 0.9 V. While it senses down to the negative rail - enabling true single-supply use - it cannot accept signals within 0.9 V of the positive rail. This limitation is explicitly defined in the "Recommended Operating Conditions" table of the SNOSCZ3B datasheet and must be accounted for in bias network design.
Can LPV801DBVT drive capacitive loads directly?
LPV801DBVT is unity-gain stable but becomes unstable with capacitive loads >50 pF directly connected to its output. For loads exceeding this threshold - such as ADC input capacitance or long PCB traces - a series isolation resistor (RISO = 30–50 kΩ) must be placed between the output and the capacitor. This technique is validated in Section 7.4.4 and Figure 37 of the official datasheet to preserve phase margin and prevent oscillation.
Is LPV801DBVT suitable for electrochemical sensor potentiostats?
Yes, LPV801DBVT is explicitly validated for electrochemical potentiostat circuits, including three-terminal CO gas sensors (TIDA-00854 reference design). Its 0.1 pA input bias current, negative-rail input, rail-to-rail output, and EMI hardening make it ideal for maintaining precise WE–RE potential and converting pA–nA sensor currents with minimal error - as confirmed in Section 8.2 of the SNOSCZ3B datasheet.
What is the thermal resistance (θJA) of LPV801DBVT in SOT-23-5 package?
The junction-to-ambient thermal resistance (θJA) of LPV801DBVT in the DBV (SOT-23-5) package is 177.4 °C/W, as measured on a standard JEDEC 2-layer test board. This value assumes no copper pour or thermal vias; adding 1-in² copper pad with 4 thermal vias reduces effective θJA to ~65 °C/W. The device's 150 °C maximum junction temperature allows continuous operation at ambient up to 85 °C under typical 450 nA loading.
