Selected Device: TSL230BRP-LF Features
The TSL230R-LF, TSL230AR-LF, and TSL230BR-LF programmable light-to-frequency converters combine a configurable silicon photodiode and a current-to-frequency converter on single monolithic CMOS integrated circuits. The output can be either a pulse train or a square wave (50% duty cycle) with frequency directly proportional to light intensity. The sensitivity of the devices is selectable in three ranges, providing two decades of adjustment. The full-scale output frequency can be scaled by one of four preset values. All inputs and the output are TTL compatible, allowing direct two-way communication with a microcontroller for programming and output interface. An output enable (OE) is provided that places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line.
- High-Resolution Conversion of Light Intensity to Frequency With No External Components
- Programmable Sensitivity and Full-Scale Output Frequency
- Communicates Directly With a Microcontroller
- Absolute Output Frequency Tolerance of +/- 5%
- Nonlinearity Error (Typically 0.2% at 100kHz)
- Stable 150 ppm/deg C Temperature Coefficient and RoHS Compliant
- RoHS Compliant

 Application Note TSL230R-Based Pulse OximeterArteries and veins carry blood throughout the body. They expand and contract with each heartbeat. During the systolic phase, the heart contracts, pushing blood into arteries, capillaries, and veins. Blood flows back to the heart from the veins during ... more info ... - Development Tool LTF EVM User Guide
