Request InfoAMS-TAOS USA Inc.Texas Advanced Optoelectronic Solutions (Taos) has introduced the TSL238T, a light-to-frequency converter that combines a silicon photodiode and a current-to-frequency converter on a single monolithic CMOS integrated circuit. Output is a square wave (50% duty cycle) with frequency directly proportional to irradiance on the photodiode. The digital output allows direct interface to a microcontroller or other logic circuitry. Temperature-compensated for the 320- to 700-nm range, the device responds from 320 to 1050 nm and operates from –25 to 70 °C. It is supplied in a compact surface-mount...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra February 2024 IssueAnalog Front End SensorThe AS7058 from ams OSRAM is an analog front end (AFE) that uses photoplethysmography (PPG) signals to improve the reliability and accuracy of wearable devices.
