DESCRIPTION

The MP5120 (single), MP5220 (dual), and

MP5420 (quad) are high-speed, high-voltage

rail-to-rail input-output amplifiers for use as

voltage reference buffers in Thin Film Transistor

Liquid Crystal Displays (TFT-LCDs). The

MP5120 family provides excellent overall

performance and versatility. The 20MHz –3dB

bandwidth and 45V/

µs slew rate make these

amplifier

suitable

for

many

portable

applications.

The MP5120, MP5220, and MP5240 are

designed to operate at supply voltages as low

as 3.2V and up to 18V at 1.6mA of supply

current per amplifier. The input can swing 0.5V

below the negative rail and 0.5V above the

positive rail. The output can swing within

100mV of each rail.

The MP5420 quad channel is available in the

space-saving 14-pin TSSOP package. The

MP5220 dual channel is available in the 8-pin

MSOP package and the MP5120 single

channel is available in 5-pin TSOT package. All

feature a standard operational amplifier pin out.
