DESCRIPTION/ORDERING INFORMATION  
The OPA336 micro-power CMOS operational amplifier (MicroAmplifier™ series) is designed for battery-powered  
applications. The device operates on a single supply, with operation as low as 2.1 V. The output is rail to rail and  
swings to within 3 mV of the supplies with a 100-kload. The common-mode range extends to the negative  
supply — ideal for single-supply applications.  
In addition to small size and low quiescent current (23 µA/amplifier), the OPA336 features low offset voltage  
(500 µV typical), low input bias current (1 pA), and high open-loop gain (115 dB).  
The device is packaged in the tiny DBV (SOT23-5) surface-mount package. It operates from –55°C to 125°C. A  
macromodel is available for download (at www.ti.com) for design analysis.

ELECTROSTATIC DISCHARGE SENSITIVITY  
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.  
Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to  
damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION  
The OPA336 operational amplifier is fabricated with a state-of-the-art 0.6-micron CMOS process. The device is  
unity-gain stable and suitable for a wide range of general-purpose applications. Power-supply pins should be  
bypassed with 0.01-µF ceramic capacitors. The OPA336 is protected against reverse battery voltages.  
Operating Voltage  
The OPA336 can operate from a 2.1-V to 5.5-V single supply voltage, with excellent performance. Most behavior  
remains unchanged throughout the full operating voltage range. Parameters that vary significantly with operating  
voltage are shown in the typical characteristics. The OPA336 is fully specified for operation from  
2.3 V to 5.5 V; a single limit applies over the supply range. In addition, many parameters are ensured over the  
specified temperature range, –55°C to 125°C.  
Input Voltage  
The input common-mode range of the OPA336 extends from (V–) – 0.2 V to (V+) – 1 V. For normal operation,  
inputs should be limited to this range. The absolute maximum input voltage is 300 mV 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 operational amplifier. Furthermore, the inputs may go beyond the power  
supplies without phase inversion (see Figure 1), unlike some other operational amplifiers.  
Normally, input bias current is approximately 1 pA. However, input voltages exceeding the power supplies can  
cause excessive current to flow in or out of the input pins. Momentary voltages greater than the power supply  
can be tolerated, as long as the current on the input pins is limited to 10 mA. This is easily accomplished with an  
input resistor (see Figure 2).

APPLICATION INFORMATION (CONTINUED)  
Capacitive Load and Stability  
The OPA336 can drive a wide range of capacitive loads. However, all operational amplifiers, under certain  
conditions, may become unstable. Operational amplifier configuration, gain, and load value are just a few of the  
factors to consider when determining stability.  
When properly configured, the OPA336 drives approximately 10,000 pF. An operational amplifier in unity-gain  
configuration is the most vulnerable to capacitive load. The capacitive load reacts with the operational amplifier  
output resistance along with any additional load resistance to create a pole in the response, which degrades the  
phase margin. In unity gain, the OPA336 performs well with a pure capacitive load, up to about 300 pF.  
Increasing gain enhances the amplifier's ability to drive loads beyond this level.  
One method of improving capacitive load drive in the unity-gain configuration is to insert a 50-to 100-Ω  
resistor inside the feedback loop (see Figure 3). This reduces ringing with large capacitive loads, while  
maintaining direct current (DC) accuracy. For example, with RL = 25 k, OPA336 performs well with capacitive  
loads in excess of 1000 pF (see Figure 4). Without the OPA336 RS, capacitive load drive typically is 350 pF for  
these conditions (see Figure 5).

Figure 5. Stability — Capacitive Load vs Resistive Load  
Alternatively, the resistor may be connected in series with the output outside of the feedback loop. However, if  
there is a resistive load parallel to the capacitive load, it and the series resistor create a voltage divider. This  
introduces a DC error at the output; however, this error may be insignificant. For instance, with  
RL = 100 kand RS = 100 , there is only about a 0.1% error at the output.  
Figure 5 shows the recommended operating regions for the OPA336. Decreasing the load resistance generally  
improves capacitive load drive. Figure 5 also shows how stability differs, depending on where the resistive load  
is connected. With G = 1 and RL = 10 kconnected to VS/2, the OPA336 typically can drive 500 pF. Connecting  
the same load to ground improves capacitive load drive to 1000 pF.

obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are  
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.  
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard  
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where  
mandated by government requirements, testing of all parameters of each product is not necessarily performed.  
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and  
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,  
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information  
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a  
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual  
property of the third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied  
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive  
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional  
restrictions.  
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all  
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not  
responsible or liable for any such statements.  
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably  
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing  
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and  
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products  
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be  
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in  
such safety-critical applications.  
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are  
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military  
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at  
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.  
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are  
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated  
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
