What are the key features of TSL6802?
- Ultra-low quiescent current: 600 nA per amplifier for multi-year battery life
- Rail-to-rail input and output for maximum dynamic range on sub-5 V rails
- Wide supply voltage range: 1.6 V to 5.5 V single-supply operation
- Cost-effective nanopower design targeting high-volume IoT and wearable applications
- Small package options enabling compact PCB layouts
- Stable unity-gain operation for buffer and follower configurations
What is TSL6802 used for?
The TSL6802 is designed for always-on sensor amplification in IoT nodes, wearables, and energy-harvesting systems where supply current must stay below 1 µA. Its 1.6 V to 5.5 V operating range covers coin-cell and single-cell LiPo applications without an additional LDO. Engineers also use it in smoke detectors, gas sensors, and portable medical devices where the 600 nA draw extends battery service intervals significantly.

Frequently Asked Questions
How does the 600 nA supply current of TSL6802 compare to a standard op amp in an IoT sensor node running on a coin cell?
A standard low-power op amp typically consumes 50 µA to 200 µA per channel, while the TSL6802 draws only 600 nA—roughly 80 to 300 times less. On a 220 mAh CR2032 coin cell, the TSL6802 alone could run continuously for over 40 years at that current, making it the right choice for always-on conditioning of sub-threshold sensor outputs.
What is the minimum supply voltage for TSL6802, and can it run directly from a single alkaline cell?
The TSL6802 operates from a minimum supply voltage of 1.6 V, well below the 1.5 V nominal of a single alkaline AA or AAA cell as it discharges to end-of-life. This means the amplifier remains functional through the entire discharge curve of a 1.5 V cell without a boost converter, reducing BOM cost in battery-operated sensing applications.
Does the rail-to-rail output of TSL6802 allow direct connection to a 1.8 V microcontroller ADC input?
Yes. The rail-to-rail output swings to within a few millivolts of both the positive and negative rails, so when the TSL6802 is powered from the same 1.8 V supply as the MCU, the full 0 V to 1.8 V ADC input range is utilized without a mid-supply level shift. This maximizes the effective number of bits on a 12-bit ADC, reducing quantization error in low-signal applications.
For a smoke detector design, what advantages does TSL6802 offer over a conventional op amp in the photodiode amplifier stage?
Smoke detectors require the amplifier to remain powered for 10-year battery lifetimes. At 600 nA supply current, the TSL6802 adds negligible drain to the 9 V alkaline battery shared with the alarm buzzer and MCU, whereas a conventional op amp consuming 50 µA would exhaust a 1200 mAh battery in under 3 years from the amplifier stage alone.
