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.

The ISL24021 is available in a 8 Ld 3mmx3mm TDFN package

featuring a standard operational amplifier pinout with a lead

pitch of 0.65mm. The device utilizes a thermally enhanced

package and has a built-in thermal protection circuit. It is

specified for operation over an ambient temperature range of

-40°C to +85°C.
