MAX8798 Overview
Key Specifications
Mount Type: Surface Mount
Operating Voltage: 5.5 V
Max Operating Temp: 85 °C
Min Operating Temp: -40 °C
Description
The MAX8798 includes a high-performance, step-up regulator; a high-speed operational amplifier; a digitally adjustable VCOM calibration device with nonvolatile memory and an I2C interface; and a high-voltage, levelshifting scan driver. The device is optimized for thin-film transistor (TFT) liquid-crystal display (LCD) applications.
Key Features
- soft-start and current limit
- The high-current operational amplifier is designed to drive the LCD backplane (VCOM)
- The amplifier features high output current (±150mA), fast slew rate (45V/µs), wide bandwidth (20MHz), and rail-to-rail inputs and outputs
- An internal 7-bit digital-to-analog converter (DAC) controls the sink current
- The DAC is ratiometric relative to BOOST and is guaranteed to be monotonic over all operating conditions
