The ADD8704 is a single-supply quad operational amplifier that has been optimized for today’s low cost TFT LCD notebook and monitor panels. Output channels A and D swing to the rail for use as end-point gamma references. Output channels B and C provide high continuous and peak current drive for use as VCOM or repair amplifiers; they can also be used as midpoint gamma references. All four amplifiers have excellent transient response and have high slew rate and capacitive load drive capability.
The document describes the ADD8704, a single-supply quad operational amplifier designed specifically for low-cost TFT LCD notebook and monitor panels. It features four channels with distinct drive capabilities: Channels A and D are optimized for end-point gamma references, while Channels B and C provide high continuous and peak current drive suitable for Vcom or repair amplifiers.
The device operates over a supply voltage range of 4.5 V to 16.5 V and is specified for an operating temperature range of -40°C to +85°C. It is available in two package types: a 14-lead TSSOP and a 16-lead LFCSP, catering to thin and portable application requirements.
