OPA349 OPA2349 OPA 349 OPA 2349 SBOS121A – APRIL 2002 1µA, Rail-to-Rail I/O CMOS OPERATIONAL AMPLIFIERS FEATURES DESCRIPTION ● ● ● ● ● ● ● ● ● ● The OPA349 and the OPA2349 are ultra-low power operational amplifiers that provide 70kHz bandwidth with only 1µA quiescent current. These rail-to-rail input and output amplifiers are specifically designed for battery-powered applications. The input common-mode voltage range extends 200mV beyond the power supply rails and the output swings to within 150mV of the rails, maintaining wide dynamic range. Unlike some micropower op amps, these parts are unity-gain stable and require no external compensation to achieve wide bandwidth. The OPA349 features a low input bias current that allows the use of large source and feedback resistors. LOW SUPPLY CURRENT: 1µA GAIN-BANDWIDTH: 70kHz UNITY GAIN STABLE LOW INPUT BIAS CURRENT: 10pA (max) WIDE SUPPLY RANGE: 1.8V to 5.5V INPUT RANGE 200mV BEYOND RAILS OUTPUT SWINGS TO 150mV OF RAILS OUTPUT DRIVE CURRENT: 8mA OPEN-LOOP GAIN: 90dB MicroPACKAGES: SC70, SOT23-5, SOT23-8 OPA349 can be operated with power supplies from 1.8V to 5.5V with little change in performance, ensuring continuing superior performance even in low battery situations.

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. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. These are stress ratings only, and functional operation of the device at these, or any other conditions beyond those specified, is not implied. (2) Input terminals are diode-clamped to the power supply rails. Input signals that can swing more than 0.5V beyond the supply rails should be current-limited to 10mA or less.

Power supply pins should be bypassed with 0.01µF ceramic capacitors. OPA349 series op amps are fully specified and tested from +1.8V to +5.5V. Parameters that vary significantly with operating voltages or temperature are shown in the Typical Characteristics Curves. The ultra low quiescent current of the OPA349 requires careful applications circuit techniques to achieve low overall current consumption. Figure 1 shows an ac-coupled amplifier +1.8 to 5.5V R3 2M R1 10M CF 3pF R5 10M CF may be required for best stability or to reduce frequency peaking—see text. G = 11 10nF OPA349 R2 10M VOUT R4 2M biased with a voltage divider. Resistor values must be very large to minimize current. The large feedback resistor value reacts with input capacitance and stray capacitance to produce a pole in the feedback network. A feedback capacitor may be required to assure stability and limit overshoot or gain peaking. Check circuit performance carefully to assure that biasing and feedback techniques meet your signal and quiescent current requirements. RAIL-TO-RAIL INPUT The input common-mode voltage range of the OPA349 series extends 200mV 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 200mV above the positive supply, while the P-channel pair is on for inputs from 200mV 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 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. For more information on designing with rail-to-rail input op amps, see Figure 3 “Design Optimization with Rail-to-Rail Input Op Amps.” FIGURE 1. AC-Coupled Amplifier.

OPA349, 2349 SBOS121A www.ti.com 9 DESIGN OPTIMIZATION WITH RAIL-TO-RAIL INPUT OP AMPS wide input swing is required. A design option would be to configure the op amp as a unity-gain inverter as shown below and hold the noninverting input at a set common-mode voltage outside the transition region. This can be accomplished with a voltage divider from the supply. The voltage divider should be designed such that the biasing point for the noninverting input is outside the transition region. In most applications, operation is within the range of only one differential pair. However, some applications can subject the amplifier to a common-mode signal in the transition region. Under this condition, the inherent mismatch between the two differential pairs may lead to degradation of the CMRR and THD. The unity-gain buffer configuration is the most problematic—it will traverse through the transition region if a sufficiently R R VOUT VIN VCM FIGURE 3. Design Optimization. COMMON-MODE REJECTION The CMRR for the OPA349 is specified in two ways so the best match for a given application may be used. First, the CMRR of the device in the common-mode range below the transition region (VCM < (V+) – 1.5V) is given. This specification is the best indicator of the capability of the device when the application requires use of one of the differential input pairs. Second, the CMRR at VS = 5V over the entire common-mode range is specified. OUTPUT DRIVEN TO V– RAIL (DUAL VERSION ONLY) Loads that connect to single-supply ground (or the V- supply pin) can cause the OPA2349 (dual version) to oscillate if the output voltage is driven into the negative rail (Figure 4a). a) Similarly, loads that can cause current to flow out of the output pin when the output voltage is near V– can cause oscillations. The op amp will recover to normal operation a few microseconds after the output is driven positively out of the rail. Some op amp applications can produce this condition even without a load connected to V–. The integrator in Figure 4b shows an example. Assume that the output ramps negatively, and saturates near 0V. Any negative-going step at VIN will produce a positive output current pulse through R1 and C1. This may incite the oscillation. Diode, D1, prevents the input step from pulling output current when the output is saturated at the rail, thus preventing the oscillation.
