12MHz Rail-to-Rail Input-Output Op Amps
The EL5120, EL5220, and EL5420 are low power, high
voltage, rail-to-rail input-output amplifiers. The EL5120
contains a single amplifier, the EL5220 contains two
amplifiers, and the EL5420 contains four amplifiers.
Operating on supplies ranging from 5V to 15V, while
consuming only 500µA per amplifier, the EL5120, EL5220,
and EL5420 have a bandwidth of 12MHz (-3dB). They also
provide common mode input ability beyond the supply rails,
as well as rail-to-rail output capability. This enables these
amplifiers to offer maximum dynamic range at any supply
voltage.
Features
The EL5120, EL5220, and EL5420 also feature fast slewing
and settling times, as well as a high output drive capability of
30mA (sink and source). These features make these
amplifiers ideal for use as voltage reference buffers in Thin
Film Transistor Liquid Crystal Displays (TFT-LCD). Other
applications include battery power, portable devices, and
anywhere low power consumption is important.
• Ultra-Small Package
The EL5420 is available in the space-saving 14 Ld TSSOP
package, the industry-standard 14 Ld SOIC package, as well
as the 16 Ld QFN package. The EL5220 is available in the
8 Ld MSOP package and the 8Ld DFN package. The
EL5120 is available in the 5 Ld TSOT package. All feature a
standard operational amplifier pin out. These amplifiers are
specified for operation with an ambient and junction
temperature range of -40°C to +125°C.
• Electronics Games
• 12MHz -3dB Bandwidth
• Supply Voltage = 4.5V to 16.5V
• Low Supply Current (per Amplifier) = 500µA
• High Slew Rate = 10V/µs
• Unity-Gain Stable
• Beyond the Rails Input Capability
• Rail-to-Rail Output Swing
• Pb-Free Available (RoHS Compliant)
Applications
• TFT-LCD Drive Circuits
• Electronics Notebooks
• Touch-Screen Displays
• Personal Communication Devices
• Personal Digital Assistants (PDA)
• Portable Instrumentation
• Sampling ADC Amplifiers
• Wireless LANs
• Office Automation
• Active Filters
• ADC/DAC Buffer

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 EL5120, EL5220, EL5420. For more information on MSL please
see tech brief TB363.
4. Not recommended for new designs. Refer to EL5x20T for possible substitutions.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
NOTES:
5. JA is measured with the component mounted on a high effective thermal conductivity test board in free air. See Tech Brief TB379 for details.
6. JA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach” features. See
Tech Brief TB379.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are
