About this manual

The ADD8709 is an 18‑channel integrated gamma reference designed for LCD TV and monitor panels. It provides high‑current gamma buffers with low offset voltage, and includes a mask‑programmable voltage regulator that isolates the gamma curve from supply ripple.

The device operates from a single supply of 7.5 V to 16.5 V, delivers up to 150 mA peak output current, and is supplied in a 48‑lead Pb‑free LQFP package. It is specified for temperatures from –40 °C to +105 °C.
