Rail-to-rail input/output and high-speed operation make them ideal for driving sampling analog-to-digital (A/D) converters. They are also well-suited for general purpose and audio applications as well as providing current/voltage conversion at the output of digital-to-analog (D/A) converters. Single, dual, and quad versions have identical specifications for design flexibility. The OPA340 series operate on a single supply as low as 2.7 V with an input common-mode voltage range that extends 500 mV below ground and 500 mV above the positive supply. Output voltage swing is to within 1 mV of the supply rails with a 100-kΩ load. They offer excellent dynamic response (BW = 5.5 MHz, SR = 6 V/µs), yet quiescent current is only 750 µA. Dual and quad designs feature completely independent circuitry for lowest crosstalk and freedom from interaction. The surface mount package options are SOIC-8 or SOT23-5 for the single (OPA340), SOIC-8 for the dual (OPA2340), and SOIC-14 surface mount for the quad (OPA4340). All are specified from –55°C to 125°C. A SPICE macromodel is available for design analysis. 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

SBOS433 – AUGUST 2008 APPLICATION INFORMATION OPA340 series operational amplifiers are fabricated on a state-of-the-art 0.6-micron CMOS process. They are unity-gain stable and suitable for a wide range of general-purpose applications. Rail-to-rail input/output 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 600-Ω loads connected to any point between V+ and ground. Rail-to-rail input and output swing significantly increases dynamic range, especially in low-supply applications. Figure 23 shows the input and output waveforms for the OPA340 in unity-gain configuration. Operation is from a single 5-V supply with a 10-kΩ load connected to VS/2. The input is a 5-VPP sinusoid. Output voltage is approximately 4.98 VPP. Power-supply pins should be bypassed with 0.01-µF ceramic capacitors. VS = +5, G = +1, RL = 10kW 5 2V/div VIN 5 VOUT apply from –55°C to 125°C. Most behavior remains nearly unchanged throughout the full operating voltage range. Parameters that vary significantly with operating voltages or temperature are shown in Typical Characteristics. Rail-to-Rail Input The input common-mode voltage range of the OPA340 series extends 500 mV 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 24). The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.3 V to 500 mV above the positive supply, while the P-channel pair is on for inputs from 500 mV below the negative supply to approximately (V+) – 1.3 V. There is a small transition region, typically (V+) – 1.5 V to (V+) – 1.1 V, in which both pairs are on. This 400-mV transition region can vary ±300 mV with process variation. Thus, the transition region (both stages on) can range from (V+) – 1.8 V to (V+) – 1.4 V on the low end, up to (V+) – 1.2 V to (V+) – 0.8 V on the high end. OPA340 series operational amplifiers are laser-trimmed to reduce the offset voltage difference between the N-channel and P-channel input stages, resulting in improved common-mode rejection and a smooth transition between the N-channel pair and the P-channel pair. However, within the 400-mV transition region PSRR, CMRR, offset voltage, offset drift, and THD may be degraded compared to operation outside this region. 0 Figure 23. Rail-to-Rail Input and Output Operating Voltage OPA340 series operational amplifiers are fully specified from 2.7 V to 5 V. Parameters are ensured over the specified supply range—a unique feature of the OPA340 series. In addition, many specifications Copyright © 2008, Texas Instruments Incorporated 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 200 fA; however, input voltages exceeding the power supplies by more than 500 mV can cause excessive current to flow in or out of the input pins. Momentary voltages greater than 500 mV beyond the power supply can be tolerated if the current on the input pins is limited to 10 mA. This is easily accomplished with an input resistor, as shown in Figure 25. Many input signals are inherently current-limited to less than 10 mA; therefore, a limiting resistor is not required.

SBOS433 – AUGUST 2008 CAPACITIVE LOAD AND STABILITY DRIVING A/D CONVERTERS OPA340 series operational amplifiers can drive a wide range of capacitive loads. However, all operational amplifiers under certain conditions may become unstable. Op amp configuration, gain, and load value are just a few of the factors to consider when determining stability. An operational amplifier in unity gain configuration is most susceptible to the effects of capacitive load. The capacitive load reacts with the operational amplifier’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, OPA340 series operational amplifiers perform well, with a pure capacitive load up to approximately 1000 pF. Increasing gain enhances the amplifier’s ability to drive more capacitance. See the typical performance curve Small-Signal Overshoot vs Capacitive Load. OPA340 series operational amplifiers are optimized for driving medium speed (up to 100 kHz) sampling A/D converters. However, they also offer excellent performance for higher speed converters. The OPA340 series provides an effective means of buffering the A/D converter’s input capacitance and resulting charge injection while providing signal gain. Figure 27 and Figure 28 show the OPA340 driving an ADS7816. The ADS7816 is a 12-bit, micro-power sampling converter in the tiny MSOP-8 package. When used with the miniature package options of the OPA340 series, the combination is ideal for space-limited and low-power applications. For further information consult the ADS7816 data sheet. With the OPA340 in a noninverting configuration, an RC network at the amplifier’s output can be used to filter high-frequency noise in the signal (see Figure 27). In the inverting configuration, filtering may be accomplished with a capacitor across the feedback resistor (see Figure 28). One method of improving capacitive load drive in the unity gain configuration is to insert a 10-Ω to 20-Ω resistor in series with the output, as shown in Figure 26. This significantly reduces ringing with large capacitive loads. However, if there is a resistive load in parallel with the capacitive load, it creates a voltage divider introducing a dc error at the output and slightly reduces output swing. This error may be insignificant. For example, with RL = 10 kΩ and RS = 20 Ω, there is only approximately 0.2% error at the output. V+ RS VOUT OPAx340 VIN 10W to 20W RL CL Figure 26.
