OPA743 OPA2743 OPA4743 OPA 743 OPA 743 OPA 743 OPA 743 ® SBOS201 – MAY 2001 12V, 7MHz, CMOS, Rail-to-Rail I/O OPERATIONAL AMPLIFIERS FEATURES DESCRIPTION ● HIGH SPEED: 7MHz, 10V/µs ● RAIL-TO-RAIL INPUT AND OUTPUT ● WIDE SUPPLY RANGE: Single Supply: 3.5V to 12V Dual Supplies: ±1.75V to ±6V ● LOW QUIESCENT CURRENT: 1.1mA ● FULL-SCALE CMRR: 84dB ● MicroSIZE PACKAGES: SOT23-5, MSOP-8, TSSOP-14 ● LOW INPUT BIAS CURRENT: 1pA The OPA743 series utilizes a state-of-the-art 12V analog CMOS process and offers outstanding AC performance, such as 7MHz GBW, 10V/µs slew rate and 0.0008% THD+N. Optimized for single supply operation up to 12V, the input common-mode range extends beyond the power supply rails and the output swings to within 100mV of the rails. The low quiescent current of 1.1mA makes it well suited for use in battery operated equipment. The OPA743 series’ ability to drive high output currents together with 12V operation makes it particularly useful for use as gamma correction reference buffer in LCD panels. For ease of use the OPA743 op-amp family is fully specified and tested over the supply range of ±1.75V to ±6V. Single, dual and quad versions are available. The single versions (OPA743) are available in the MicroSIZE SOT23-5 and in the standard SO-8 surface-mount, as well as DIP-8 packages. Dual versions (OPA2743) are available versions in the MSOP-8, SO-8, and DIP-8 packages. The quad versions (OPA4743) are available in the TSSOP-14 and SO-14 packages. All are specified for operation from –40°C to +85°C.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. NOTES: (1) Stresses above these ratings may cause permanent damage. Exposure to absolute maximum conditions for extended periods may degrade device reliability. (2) Input terminals are diode-clamped to the power supply rails. Input signals that can swing more than 0.3V beyond the supply rails should be current-limited to 10mA or less. (3) Short-circuit to ground, one amplifier per package. 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.

The OPA743 is unity-gain stable and offers 7MHz bandwidth and 10V/µs slew rate. +V IOVERLOAD 10mA max VOUT OPA743 VIN Rail-to-rail input and output swing helps maintain dynamic range, especially in low supply applications. Figure 1 shows the input and output waveforms for the OPA743 in unitygain configuration. On a ±6V supply with a 100kΩ load connected to VS /2. The output is tested to swing within 100mV to the rail. FIGURE 2. Input Current Protection for Voltages Exceeding the Supply Voltage. Power-supply pins should be bypassed with 1000pF ceramic capacitors in parallel with 1µF tantalum capacitors. INPUT VOLTAGE 8 G = +1, VS ± 6V Input 6 4 2V/div 2 0 –2 –4 R V– Device inputs are protected by ESD diodes that will conduct if the input voltages exceed the power supplies by more than approximately 300mV. Momentary voltages greater than 300mV beyond the power supply can be tolerated if the current is limited to 10mA. This is easily accomplished with an input resistor, in series with the op amp input as shown in Figure 2. Many input signals are inherently current-limited to less than 10mA; therefore, a limiting resistor is not always required. The OPA743 features no phase inversion when the inputs extend beyond supplies if the input current is limited, as seen in Figure 3. –6 Output (Inverted on osciloscope) –8 20µs/div VS = ±6V, VIN = 13Vp-p, G = +1 OPERATING VOLTAGE OPA743 series op amps are fully specified and guaranteed from 3.5V to 12V over a temperature range of –40ºC to +85ºC. 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 OPA743 series extends 100mV beyond the supply rails at room temperature. This is achieved with a complementary input stage—an Nchannel input differential pair in parallel with a P-channel differential pair. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 2.0V to 100mV above the positive supply, while the P-channel pair is on for inputs from 100mV below the negative supply to approximately (V+) – 1.5V. There is a small transition region, typically (V+) – 2.0V to (V+) – 1.5V, in which both pairs are on. This 500mV transition region can vary ±100mV with process variation. Thus, the transition region (both stages on) can range from (V+) – 2.1V to (V+) – 1.4V on the low end, up to (V+) – 1.9V to (V+) – 1.6V on the high end. Most railto-rail op amps on the market use this two input stage approach, and exhibit a transition region where CMRR, offset voltage, and THD may vary compared to operation outside this region.

RAIL-TO-RAIL OUTPUT A class AB output stage with common-source transistors is used to achieve rail-to-rail output. This output stage is capable of driving 1kΩ loads connected to any point between V+ and V–. For light resistive loads (> 100kΩ), the output voltage can swing to 100mV from the supply rail. With 1kΩ resistive loads, the output can swing to within 325mV from the supply rails while maintaining high openloop gain (see the typical performance curve “Output Voltage Swing vs Output Current”). 9 CAPACITIVE LOAD AND STABILITY The OPA743 series op amps can drive up to 1000pF pure capacitive load. Increasing the gain enhances the amplifier’s ability to drive greater capacitive loads (see the typical performance curve “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 inside the feedback loop, as shown in Figure 4. This reduces ringing with large capacitive loads while maintaining DC accuracy. RS 20Ω OPA743 VOUT VIN RL CL FIGURE 4.

REFERENCE BUFFER FOR LCD SOURCE DRIVERS In modern high resolution TFT LCD displays, gamma correction must be performed to correct for nonlinearities in the glass transmission characteristics of the LCD panel. The typical LCD source driver for 64 Bits of Grayscale uses internal DAC to convert the 6-Bit data into analog voltages applied to the LCD. These DAC typically require external voltage references for proper operation. Normally these external reference voltages are generated using a simple resistive ladder, like the one shown in Figure 6. Typical laptop or desktop LCD panels require 6 to 8 of the source driver circuits in parallel to drive all columns of the panel. Although the resistive load of one internal string DAC is only around 10kΩ, 6 to 8 in parallel represent a very substantial load. The power supply used for the LCD source drivers for laptops is typically in the order of 10V. To maximize the dynamic range of the DAC, rail-to-rail output performance is required for the upper and lower buffer. The OPA4743’s ability to operate on 12V supplies, to drive heavy resistive loads (as low as 1kΩ), and to swing to within 325mV of the supply rails, makes it very well suited as a buffer for the reference voltage inputs of LCD source drivers. During conversion, the DAC’s internal switches create current glitches on the output of the reference buffer. The capacitor CL (typically 100nF) functions as a charge reservoir that provides/absorbs most of the glitch energy. The series resistor RS isolates the outputs of the OPA4743 from the heavy capacitive load and helps to improve settling time. +V V– VOUT –2.5V 1/2 OPA2743 Ref Negative Reference 500pF V+ 500pF 1/2 OPA2743 VOUT +2.5V Ref Positive Reference –V FIGURE 5.
