12MHz Rail-to-Rail Input-Output Operational Amplifier
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.
Features
• 12MHz (-3dB) Bandwidth
• 4.5V to 19V Maximum Supply Voltage Range
• 12V/µs Slew Rate
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.
• 550µA Supply Current (per Amplifier)
• ±65mA Continuous Output Current
• ±200mA Output Short Circuit Current
• Unity-gain Stable
• Beyond the Rails Input Capability
• Rail-to-rail Output Swing
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 solution for use in TFT-LCD panels as a
