MP5120, MP5220, MP5420
High Speed, +/-9V, Rail-to-Rail Input-Output
Op Amps
The Future of Analog IC Technology
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.

Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature T
J
(MAX), the junction-to-
ambient thermal resistance
θ
JA
, and the ambient temperature
T
A
. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by P
D
(MAX) = (T
J
(MAX)-T
A
)/θ
JA
. Exceeding the maximum allowable power
dissipation will cause excessive die temperature, and the
regulator will go into thermal shutdown. Internal thermal
shutdown circuitry protects the device from permanent
damage.
3) The device is not guaranteed to function outside of its
operating conditions.
4) Measured on JESD51-7, 4-layer PCB.
