Overview

The TLV8801DBVR is an ultra-low-power single operational amplifier designed for cost-sensitive, battery-powered sensing applications. Operating at a typical supply current of 450nA and a low voltage range of 1.7V to 5.5V, it is optimized for high-impedance sensors where power efficiency is the primary design constraint.

Why Choose This Part

The primary advantage is the sub-microamp current consumption (450nA) combined with rail-to-rail output and EMI protection. Its low input bias current of 0.1pA minimizes error when used with high-impedance sources, and its unity-gain stability ensures simple, robust circuit designs.

Applications

PIR Motion Detectors
Serves as the front-end amplifier for Passive Infrared sensors in security systems to maximize battery life.
Gas and CO Detectors
Ideal for amplifying micro-amp signals from electrochemical gas sensors in residential safety devices.
Ionization Smoke Alarms
Utilizes the extremely low 0.1pA input bias current to interface with high-impedance ionization chambers.
Remote Environmental Sensors
Enables long-term monitoring in IoT nodes powered by coin-cell batteries or energy harvesting.
