Notes:
(1) Reset until clock pulse 18 (on declining flank).
Minimum integration time = (133-18) * CLK period + 10µs (this is the time the S&H cap needs to follow).
At 1MHz clock speed, the minimum integration time becomes 0.125ms.
(2) At 125°C, the integration time should be limited to 2ms.
(3) The SI pulse must go low before the rising edge of the next clock pulse.

Exposure to absolute-maximum -rated conditions for extended periods may affect device reliability.
6 Cosine Correction
When using a single LED light source, which is placed above the middle of the die, the light intensity that
falls onto the outer pixels is lower than the light intensity that falls onto the middle pixels (due to the
distance die-LED, the shape of the LED light emission and the sensitivity of pixels vs. angle of incident
light). To compensate for these effects, each pixel in the array has a slightly different gain correction with
respect to the centre of the array. For a light source to photodiode array distance of 15mm the relative
pixels sensitivities are shown in the table below.
