12MHz Rail-to-Rail Input-Output Operational Amplifier
EL5220T
Features
• 12MHz (-3dB) Bandwidth
The EL5220T is a high voltage rail-to-rail input-output
amplifier with low power consumption. The EL5220T
contains two amplifiers. Each amplifier exhibits beyond
the rail input capability, rail-to-rail output capability and
is unity gain stable.
• 4.5V to 19V Maximum Supply Voltage Range
• 12V/μs Slew Rate
• 550μA Supply Current (per Amplifier)
• ±65mA Continuous Output Current
• ±200mA Output Short Circuit Current
• Unity-gain Stable
The maximum operating voltage range is from 4.5V to
19V. It can be configured for single or dual supply
operation, and typically consumes only 550μA per
amplifier. The EL5220T has an output short circuit
capability of ±200mA and a continuous output current
capability of ±65mA.
• Beyond the Rails Input Capability
• Rail-to-rail Output Swing
• Built-in Thermal Protection
The EL5220T features a slew rate of 12V/μs. Also, the
device provides common mode input capability beyond
the supply rails, rail-to-rail output capability, and a
bandwidth of 12MHz (-3dB). This enables the amplifiers
to offer maximum dynamic range at any supply voltage.
These features make the EL5220T an ideal amplifier

The EL5220T is available in an 8 Ld MSOP package, and a
thermally enhanced 8 Ld DFN package. Both feature a
standard operational amplifier pinout. The devices
operate over an ambient temperature range of -40°C to
+85°C.
