(Note 6)
Note 1. Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for
stress ratings. Functional operation of the device at these or any other conditions beyond those indicated in the
operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended
periods may remain possibility to affect device reliability.
Note 2. θJA is measured in the natural convection at TA = 25°C on a high effective thermal conductivity test board (4-Layers,
2S2P) of JEDEC 51-7 thermal measurement standard.
Note 3. Devices are ESD sensitive. Handling precaution is recommended.
Note 4. The device is not guaranteed to function outside its operating conditions.
Note 5. 16.5V is the correct allowable aging voltage; however, full electrical characteristics are specified with a single nominal
supply voltage from 5V to 15V or a split supply with its total range from 5V to 15V.
Note 6. Slew rate is measured on rising and falling edges.

Applications Information
The RT9136 is specified with a single nominal supply
voltage from 5V to 15V or a split supply with its total
range from 5V to 15V. Correct operation is guaranteed for
a supply range of 4.5V to 16.5V.
RT9136 specifications are stable over both the full supply
range and operating temperatures of −40°C to 85°C .
Parameter variations with operating voltage and/or
temperature are shown in the typical performance curves.
The output swing of the RT9136 typically extends to within
80mV of positive/negative supply rails with 5mA load
current source/sink. Decreasing the load current will get
output swing even closer to the supply rails. Figure 1
shows the rail-to-rail input and output waveforms in the
unit gain configuration without load current. The supply
rails are ±5V. Applying an input 10Vp_p sinusoidal
waveform results in a 9.8Vp_p output voltage as shown in
Figure 1.
Short Circuit Condition
An internal short-circuit protection circuit is implemented
to protect the device from output short circuit. The RT9136
limits the short circuit current to ±120mA if the output is
directly shorted to positive/negative supply rails. For
reliability, the continuous output current more than ±35mA
is not recommended.
The RT9136 is mainly designed for LCD gamma and
V-com buffer. OP Amplifier-C has 120mA instantaneous
source/sink peak current. To test the performance of the
RT9136 for LCD driving capability, the test circuit is to
simulate the V-com driver as shown Figure 2. Series
capacitors and resistors connected to the output of the
OP simulate the load of LCD panel. The 300Ω and 3kΩ
feedback resistors are used to improve the settling time.
This circuit is the worst case for a V-com buffer. Figure 3
shows the waveforms of the output peak current capability.

Output Voltage
(5V/Div)
The RT9136 packaged in quad operational amplifiers has
high performance to drive large load for different application.
High slew rates, rail-to-rail input and output capability and
low power consumption are the features to make the
RT9136 ideal for LCD applications. The RT9136 also has
wide bandwidth and phase margin to drive a load of 10kΩ
and 10pF.
