Data Sheet
1A Rail-to-Rail Input-Output
Operational Amplifier
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 V_COM 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.

NOTE: These Intersil Pb-free plastic packaged products employ
special Pb-free material sets, molding compounds/die attach
materials, and 100% matte tin plate plus anneal (e3 termination
finish, which is RoHS compliant and compatible with both SnPb and
Pb-free soldering operations). Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020.
