DATASHEET
ISL24021
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.

NOTES:
1. Please refer to
TB347
for details on reel specifications.
2. 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.
3. For Moisture Sensitivity Level (MSL), please see device information
page for
ISL24021.

NOTES:
6. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
7. Measured over the -40°C to +85°C ambient operating temperature range.
8. Typical slew rate is an average of the slew rates measured on the rising (20% to 80%) and the falling (80% to 20%) edges of the output signal.
9. Settling time measured from [Full Scale - (0.1%*StepSize)] on the rising edge to when the output is bounded within ±0.1% of full scale.
10. Continuous output current with a typical of ±300mA. Care should be taken to ensure the maximum package power dissipation is not exceeded, refer
to “Power Dissipation” on page 10.
