01 12-bit digital output

Transcription

1 12-bit digital output The is a digital color sensor sensitive to red (λ=615 nm), green (λ=540 nm) and blue (λ=465 nm) regions of the spectrum. Detected signals are serially output as 12-bit digital data. uilt-in three 12-bit registers allow simultaneous measurement of three colors. Sensitivity level is adjustable in two steps to cover a wide photometric range. Features 12-bit digital output Simultaneous measurement of three colors 2-step sensitivity switching (sensitivity ratio of 1 : 9) voltage (3.3 V) operation CMOS monolithic photo IC No external components required Applications Display color adjustment Various applications involving color detection Feature bit digital output Feature 02 Simultaneous measurement of three colors Light signals detected by the photodiode are amplified and converted into 12-bit digital signals. An amplifier is also formed for each of the photodiode elements arrayed in the mosaic pattern, allowing simultaneous accurate measurement of the components of The photodiode consists of 9 9 elements arrayed in a mosaic pattern. Each element has an on-chip filter that it sensitive to one color of light, either red (λp=615 nm), green (λp=540 nm) or blue (λp=465 nm). incident light. lock diagram Spectral response Vdd I/F I/F egister egister Serial converter ange Dout CK elative sensitivity lue reen (Typ.

2 Feature 03 2-step sensitivity switching To enable measurement over a wide range of illuminance, the photodiode sensitivity can be selected from two setting modes (high sensitivity mode and low sensitivity mode). The photodiode photosensitive area used to detect light differs depending on which sensitivity mode is selected (high sensitivity mode: 9 9 elements, low sensitivity mode: 3 3 elements in center).

(4) After the desired integration time (tg) has passed, set the ate terminal from to to end the light intensity integration. (5) Measurement data is output from the Dout terminal by inputting 36 CK pulses to the CK terminal. Note 1: A total of 36 CK pulses are required to read out 3-color measurement data. ed data is output by the first 12 pulses, green data by the next 12 pulses, and blue data by the last 12 pulses. Measurement data is output from the LS side. Note 2: Measurement data changes at the CK pulse rising edge. Note 3: Do not switch the ange terminal during integration time (tg). KPICC0115E 4
