TSL2584TSV − Detailed Description

The TSL2584TSV contains two integrating analog-to-digital

converters (ADC) that integrate currents from two photodiodes.

Integration of both channels occurs simultaneously. Upon

completion of the conversion cycle, the conversion result is

transferred to the Channel 0 and Channel 1 data registers. The

transfers are double-buffered to ensure that the integrity of the

data is maintained. After the transfer, the device automatically

begins the next integration cycle.

Communication with the device is accomplished through a

standard, two-wire I²C serial bus. Consequently, the

TSL2584TSV can be easily connected to a microcontroller or

embedded controller. No external circuitry is required for signal

conditioning. Because the output of the device is digital, the

output is effectively immune to noise when compared to an

analog signal.

The TSL2584TSV also supports an interrupt feature that

simplifies and improves system efficiency by eliminating the

need to poll a sensor for a light intensity value. The primary

purpose of the interrupt function is to detect a meaningful

change in light intensity. The concept of a meaningful change

can be defined by the user both in terms of light intensity and

time, or persistence, of that change in intensity. The device has

the ability to define thresholds above and below the current

light level. An interrupt is generated when the value of a

conversion exceeds either of these limits.
