DESCRIPTION
The UTC OPA2336 is a CMOS operational amplifier. It is
operated on a 2.1V (Min.) single supply. A100kΩ load is driven by
the rail-to-rail output and the accuracy of the output voltage is
ensured at ± 3mV.
The UTC OPA2336 is characterized by its low quiescent current
(20μA/amplifier), low offset voltage (125μV max), low input bias
current (1pA), and high open-loop gain (115dB).
The UTC OPA2336 features completely independent circuitry
for lowest crosstalk and freedom from interaction.
The UTC OPA2336 is particularly designed for battery-powered
applications and the common-mode range extending to the negative
supply makes it ideal for single-supply applications.
In addition to the applications mentioned above, the UTC
OPA2336 is suitable for portable devices, high-Impedance
applications, photodiode, pre-amps, precision integrators, medical
instruments, and test equipment.

APPLICATION INFORMATION
The UTC OPA2336 is a CMOS operational amplifier, its outstanding features and functions make it suitable for
several applications. The UTC OPA2336 is unity-gain stable and can be protected under the reverse battery
voltages conditions. 0.01μF ceramic capacitors are required to bypass the power supply.
OPERATING VOLTAGE
The UTC OPA2336 is operating on a single supply ranging from 2.1V to +5.5V, most behavior remains
unchanged throughout the full operating voltage range. The UTC OPA2336 is fully specified for operation from
+2.3V to +5.5V; a single limit applies over the supply range. Moreover, this device performs well over a temperature
range of -40°C to +85°C.
INPUT VOLTAGE
The UTC OPA2336 allows input common-mode range varies from (V-)-0.2V to (V+)-1V, normal behaviors should
operate within this range. In addition, the absolute maximum input voltage is 300mV beyond the supplies. Thus,
inputs greater than the input common-mode range but less than maximum input voltage, while not valid, will not
cause any damage to the op-amp.
Normally, input bias current is approximately 1pA. However, the input pin may be applied to an excess inrush
current, which is encountered when input voltages are higher than the power supplies. This device is not damaged
unless the current on the input pins is less than 10mA. This is easily accomplished with an input resistor, as shown
in Figure 1.

CAPACITIVE LOAD AND STABILITY
The UTC OPA2336 under certain conditions may become unstable. For device’s stability, there are many
factors considered besides the amplifier gain, load value and so on.
The UTC OPA2336 can drive a wide range of capacitive loads, it can drive approximately 10,000pF when
properly configured. An op amp in unity-gain configuration is the most vulnerable to capacitive load. The capacitive
load reacts with the op amp’s output resistance, along with any additional load resistance, to create a pole in the
response which degrades the phase margin. In unity gain, 300pF capacitive load is to be optimal for the UTC
OPA2336. Increasing gain enhances the amplifier’s ability to drive loads beyond this level.
In order to improve capability of driving capacitive load in the unity-gain configuration, a 50Ω to 100Ω resistor is
expected to locate inside the feedback loop, as shown in Figure 2. This reduces ringing with large capacitive loads
while maintaining DC accuracy.
