This news release introduces TAOS's TSL257 optical converter, which provides high sensitivity, low noise and positive offset without sacrificing speed. The converter is integrated in a small, single monolithic IC and is well suited for smoke, mark and color detection applications as well as in proximity sensors and ambient light systems for contrast control.
TAOS, Inc. released a new light‑to‑voltage optical converter, the TSL257, which integrates a photodiode, operational amplifier and feedback components on a single monolithic IC. The device is designed for low‑light environments such as smoke, mark, color detection, proximity sensors and ambient‑light contrast control.
The TSL257 provides 320 MΩ transimpedance gain, a 160 µs rise time, and is factory‑trimmed for a small positive offset. It ships in a 3‑lead clear plastic sidelooker package with an integral lens and is priced at $0.77 per 1,000 pieces.
