The ISL24021 is a high output current, high voltage, rail-to-rail voltage feedback amplifier. The ISL24021 is capable of 1A peak output short circuit current. The amplifier exhibits beyond the rail input capability, rail-to-rail output capability and is unity gain stable. The operating supply voltage range is from 4.5V to 19V maximum and the ISL24021 can be configured for single or dual supply operation. The ISL24021 has the ability to quickly source and sink large peak currents up to 1A and to drive large continuous currents of 300mA. The ISL24021 features fast slewing and settling times. Also, the device provides common mode input capability beyond the supply rails, and rail-to-rail output capability. This enables the amplifier to offer maximum dynamic range at any supply voltage. These features make the ISL24021 an ideal solution as a VCOM driver in TFT-LCD panel applications. Other applications may include battery power and portable devices, and especially where low power consumption is important.
