What are the key features of TSL6804?
- Ultra-low 600 nA quiescent current extends battery life in always-on sensing applications such as smoke detectors and energy harvesters
- Rail-to-rail input and output swings maximize dynamic range on a 5 V single supply, eliminating the need for a negative rail
- Cost-effective design reduces BOM cost while maintaining adequate bandwidth for low-frequency sensor signal conditioning below 10 kHz
What is TSL6804 used for?
The TSL6804 is ideal for battery-operated sensor nodes, smoke detectors, and wearable health monitors where every nanoamp counts and the op amp must operate continuously for months or years without a battery change. Its rail-to-rail output allows direct interfacing with low-voltage ADC inputs on microcontrollers running at 3.3 V or 5 V without signal clipping. The device also fits energy-harvesting circuits and industrial 4–20 mA transmitter loops where a nanopower amplifier must buffer or amplify a small sensor signal with minimal self-heating.

Frequently Asked Questions
How does the TSL6804's 600 nA quiescent current compare with standard op amps in IoT sensor designs?
At 600 nA, the TSL6804 draws 100× to 1000× less quiescent current than a typical general-purpose op amp drawing 0.5 mA to 1 mA, allowing a 100 mAh coin cell to power the amplifier stage for over 190,000 hours—effectively eliminating op amp power as a battery-life concern.
What is the supply voltage range for the TSL6804, and does it support single-supply operation?
The TSL6804 operates from a single supply of 1.8 V to 5.5 V, covering common microcontroller rail voltages of 1.8 V, 3.3 V, and 5 V. Rail-to-rail input and output allow the output to swing within millivolts of both supply rails on a single 3.3 V supply without a negative rail.
In which sensor conditioning circuits does the nanopower TSL6804 outperform a standard 500 µA op amp?
In continuous-monitoring circuits such as gas-leak detectors, passive infrared sensors, and glucose monitors, the TSL6804's 600 nA supply current vs. 500 µA for a conventional op amp reduces the amplifier's share of system power by over 800×, extending a 500 mAh battery life from weeks to years in always-on configurations.
What package does the TSL6804 come in and how does that affect PCB layout in wearable designs?
The TSL6804 is available in a small outline (SOP) package with a 1.27 mm pitch, offering a compact footprint of roughly 3 mm × 5 mm that fits easily on flexible or rigid PCBs used in wrist-worn wearables and coin-cell-powered patch sensors.
