The TSL1020 is composed of 20 + 1 channel buffers which are used to buffer the reference voltage for gamma correction in thin film transistor (TFT) liquid crystal displays (LCD). One COM amplifier is able to deliver high output current, up to 150mA. Amplifiers A and B feature positive single supply inputs for common mode voltage, thus can be used for the highest gamma voltages. The amplifiers C to T inclusive, and the COM amplifier, feature negative single supply inputs and are dedicated to the lowest gamma voltages.
