They are optimized for low-voltage, single-supply operation. Rail-to-rail input and output and high-speed operation make them ideal for driving sampling Analog-to-Digital (A/D) converters. The power-saving shutdown feature makes the OPA341 ideal for portable low-power applications. The OPA341 series is also well suited for general-purpose and audio applications as well as providing I/V conversion at the output of Digital-to-Analog (D/A) converters. Single and dual versions have identical specifications for design flexibility. The OPA341 series operate on a single supply as low as 2.5V, and input common-mode voltage range extends 300mV beyond the supply rails. Output voltage swings to within 1mV of the supply rails with a 100kΩ load. The OPA341 series offers excellent dynamic response (BW = 5.5MHz, SR = 6V/µs) with a quiescent current of only 750µA. The dual design features completely independent circuitry for lowest crosstalk and freedom from interaction. The single (OPA341) packages are the tiny SOT23-6 surface mount and SO-8 surface mount. The dual (OPA2341) comes in the miniature MSOP-10 surface mount. All are specified from –55°C to +125°C and operate from –55°C to +150°C. The OPA343 provides similar performance without shutdown capability.

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.

They are unity-gain stable and suitable for a wide range of general-purpose applications. Rail-to-rail I/O make them ideal for driving sampling A/D converters. In addition, excellent ac performance makes them well suited for audio applications. The class AB output stage is capable of driving 600Ω loads connected to any point between V+ and ground. Rail-to-rail input and output swing significantly increases dynamic range, especially in lowsupply applications. Figure 1 shows the input and output waveforms for the OPA341 in unity-gain configuration. Operation is from a single +5V supply with a 10kΩ load connected to VS /2. The input is a 5Vp-p sinusoid. Output voltage is approximately 4.98Vp-p. Power-supply pins should be bypassed with 0.01µF ceramic capacitors. VS = 5, G = +1, RL = 10kΩ OPERATING VOLTAGE OPA341 series op amps are fully specified from +2.7V to +5.5V. However, supply voltage may range from +2.5V to +5.5V. Parameters are tested over the specified supply range—a unique feature of the OPA341 series. In addition, many specifications apply from –55°C to +125°C. Most behavior remains virtually unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltages or temperature are shown in the Typical Characteristics. RAIL-TO-RAIL INPUT The input common-mode voltage range of the OPA341 series extends 300mV beyond the supply rails. This is achieved with a complementary input stage—an N-channel input differential pair in parallel with a P-channel differential pair, as shown in Figure 2. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.3V to 300mV above the positive supply. The P-channel pair is on for inputs from 300mV below the negative supply to approximately (V+) – 1.3V. There is a small transition region, typically (V+) – 1.5V to (V+) – 1.1V, in which both input pairs are on. This 400mV transition region can vary ±300mV with process variation. Thus, the transition region (both stages on) can range from (V+) – 1.8V to (V+) – 1.4V on the low end, up to (V+) – 1.2V to (V+) – 0.8V on the high end. Within the 400mV transition region PSRR, CMRR, offset voltage, offset drift, and THD may be degraded compared to operation outside this region. VIN 2V/div VOUT 20µs/div FIGURE 1.

OPA341, 2341 SBOS202A 9 A double-folded cascode adds the signal from the two input pairs and presents a differential signal to the class AB output stage. Normally, input bias current is approximately 600fA, however, input voltages exceeding the power supplies by more than 300mV can cause excessive current to flow in or out of the input pins. Momentary voltages greater than 300mV beyond the power supply can be tolerated if the current on the input pins is limited to 10mA. This is easily accomplished with an input resistor, as shown in Figure 3. Many input signals are inherently current-limited to less than 10mA, therefore, a limiting resistor is not required. capacitive load reacts with the op amp’s output resistance, along with any additional load resistance, to create a pole in the small-signal response which degrades the phase margin. In unity gain, OPA341 series op amps perform well, with a pure capacitive load up to approximately 1000pF. Increasing gain enhances the amplifier’s ability to drive more capacitance. See the typical characteristic “Small-Signal Overshoot vs Capacitive Load.” One method of improving capacitive load drive in the unitygain configuration is to insert a 10Ω to 20Ω resistor in series with the output, as shown in Figure 4. This significantly reduces ringing with large capacitive loads. However, if there is a resistive load in parallel with the capacitive load, RS creates a voltage divider. This introduces a DC error at the output and slightly reduces output swing. This error may be insignificant. For instance, with RL = 10kΩ and RS = 20Ω, there is only about a 0.2% error at the output. DRIVING A/D CONVERTERS OPA341 series op amps are optimized for driving medium speed (up to 100kHz) sampling A/D converters. However, they also offer excellent performance for higher-speed converters. The OPA341 series provides an effective means of buffering the A/D converter’s input capacitance and resulting charge injection while providing signal gain. For applications requiring high accuracy, the OPA340 series is recommended. The OPA341 implements a power-saving shutdown feature particularly useful for low-power sampling applications. Figure 5 shows the OPA341 driving the ADS7816, a 12-bit micro-power sampling converter available in the tiny MSOP-8 package. With the OPA341 in non-inverting configuration, an RC network at the amplifier’s output is used as an anti-aliasing filter. By tying the enable of the OPA341 to the shutdown of the ADS7816, additional power-savings can be used for sampling applications. To effectively drive the ADS7816, timing delay was introduced between the two devices, see Figure 5. Alternative applications may need additional timing adjustments. Figure 6 shows the OPA341 configured as a speech bandpass filter. Figure 7 shows the OPA341 configured as a transimpedance amplifier. V+ IOVERLOAD 10mA max VIN OPAx341 VOUT FIGURE 3. Input Current Protection for Voltages Exceeding the Supply Voltage. RAIL-TO-RAIL OUTPUT A class AB output stage with common-source transistors is used to achieve rail-to-rail output. For light resistive loads (> 50kΩ), the output voltage is typically a few millivolts from the supply rails. With moderate resistive loads (2kΩ to 50kΩ), the output can swing to within a few tens of millivolts from the supply rails and maintain high open-loop gain. See the typical characteristic “Output Voltage Swing vs Output Current.” CAPACITIVE LOAD AND STABILITY OPA341 series op amps can drive a wide range of capacitive loads. However, all op amps under certain conditions may become unstable. Op amp configurations, gain, and load value are just a few of the factors to consider when determining stability. An op amp in unity-gain configuration is the most susceptible to the effects of capacitive load. The V+ RS OPAx341 VIN 10Ω to 20Ω RL CL VOUT VENABLE FIGURE 4.
