The ADD8502 is an integrated, high accuracy, programmable grayscale generator. Two sets of five output reference voltages are mask programmed to 0.2% resolution. The outputs switch between the two sets of five levels. The reference levels are selected from a 512 tap resistor network using a via mask. ADD8502 includes two serially addressable, 10-bit digital-to-analog converters (DACs) and five fast, low current buffers. The dual DACs set the endpoint voltages applied to the resistor network to adjust for flicker and range.
The ADD8502 is an integrated, high‑accuracy grayscale generator featuring two mask‑programmable sets of five reference levels and dual 10‑bit DACs for flicker offset and range adjustment. It operates from a single 5 V supply and offers ultra‑low power modes down to 1 pA.
The device is supplied in a 24‑lead 4 mm × 4 mm LFCSP package, supports CMOS/TTL logic inputs, and is rated for an industrial temperature range of –40 °C to +85 °C. Detailed specifications, pin configurations, and performance graphs are provided.
