Description
The TSL1018 is composed of 18 + 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 value, up to ±150mA. Amplifiers A and B
feature positive single supply inputs for common
mode voltage, thus can be used for highest
gamma voltages. The amplifiers C to R inclusive,
and the COM amplifier, feature negative single
supply inputs and are dedicated to the lowest
gamma voltages.
The TSL1018 is fully characterized and
guaranteed over a wide industrial temperature
range (-40 to +95°C).
