1. A sensor assembly comprising:
a first die including a pixel array composed of color pixels that detect light in one or more color channels and sparse pixels, wherein the color pixels and the sparse pixels are arranged to form a plurality of macro pixels, and each macro pixel includes a respective subset of the color pixels and a respective subset of the sparse pixels; and
a second die positioned below and coupled to the first die, the second die including an analog-to-digital converter (ADC) array that is communicatively coupled to the sparse pixels such that each subset of the sparse pixels has a single corresponding ADC in the ADC array.
