MP5121, MP5221, MP5421
High Speed, Rail-to-Rail Input-Output, and
Single-Supply Op Amps
The Future of Analog IC Technology
DESCRIPTION
The MP5121(single), MP5221(dual), and
MP5421(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
MP5121 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 MP5121, MP5221, and MP5421 are
designed to operate at supply voltages as low
as 3.2V and up to 20V at 1.6mA of supply
current per amplifier. The MP5121 family has
true single supply capability. 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 MP5421 quad channel is available in the
space-saving 14-pin TSSOP package. The
MP5221 Dual channel is available in the 8-pin
MSOP package and the MP5121 single
channel is available in 5-pin TSOT package. All
feature a standard operational amplifier pin out.
