The OPB780Z reflective color sensor assembly features high-resolution conversion of light intensity to frequency, selectable color output frequency, direct communication with a microcontroller, sensor power supply operation (2.7 V to 5.5 V), and a separate LED power input.
The OPB780Z is a reflective color sensor that converts light intensity to a frequency output. It contains a 64‑photodiode array (8 × 8) with separate red, green, blue, and clear groups, and a built‑in white LED for miniature applications. The sensor output is a 50 % duty‑cycle square wave proportional to reflected light intensity, and it can be driven directly by TTL or CMOS logic.
The document lists absolute maximum ratings, recommended operating conditions, electrical and electro‑optical characteristics, and pin descriptions. It also includes typical performance curves, spectral response data, and wiring information such as the 10‑inch flat‑flex cable and its AVX connector.
