If you require a reliable and high-performance proximity sensor for your application, the TSL2772EVM Proximity Light Digital Converter can be a good choice. However, it is recommended to carefully evaluate the costs and requirements of the application before making a decision. If the cost is a concern, there are other proximity sensors available in the market that may offer similar performance at a lower cost.

Details:

The interrupt feature simplifies and improves system efficiency by eliminating the need to poll a sensor for a light intensity or proximity value. The digital output of the device is inherently more immune to noise when compared to an analog interface. The number of proximity led pulses can be programmed from 1 to 255 pulses.

When interrupts are enabled and a pre set value is exceeded, the interrupt pin is asserted and remains asserted until cleared by the controlling firmware. Interrupt thresholds and persistence settings are configured independently for both Al's and proximity. The tsl2772 light to digital device provides on chip photo diodes, integrating amplifiers, ADC, accumulators, clocks, buffers, compactors, a state machine, and an i2c interface.

No external current limiting resistor is required. The power can also be reduced by a factor of 8 with the PD bit. Communication to the device is accomplished through a fast up to 400 khz, two wire i2c serial bus for easy connection to a micro controller or embedded controller. Upon completion of the conversion cycle, the conversion result is transferred to the data registers.

Each pulse has a 16 period. This digital output can be read by a microprocessor through which the illuminates ambient light level in lux is derived using an empirical formula to approximate the human eye response. The programmable led current, coupled with the programmable number of pulses, provides a 16,000 1 contiguous dynamic range.

In addition, a programmable interrupt persistence feature allows the user to determine how many consecutive exceeded thresholds are necessary to trigger an interrupt. Two integrating ADC simultaneously convert the amplified photo diode currents into a digital value providing up to 16 bits of resolution. The device provides a separate pin for level interrupts. Each device combines a channel photo diode ch0, which is responsive to both visible and infrared light, and a channel 1 photo diode ch1, which is responsive primarily to infrared light.

Proximity detection requires only a single external Ir led.
