The P-channel pair is on for inputs from 500mV below the negative supply to approximately (V+) – 1.3V. V = +5, G = +1, R = 10kΩ S L There is a small transition region, typically (V+) – 1.5V to (V+) – 1.1V, in which both input pairs are on. This 400mV 5 transition region can vary ±300mV with process variation. VIN Thus, the transition region (both stages on) can range from (V+) – 1.8V to (V+) – 1.4V on the low end, up to (V+) v V/di – 1.2V to (V+) – 0.8V on the high end.

See the typical performance curve “Small-Signal Overshoot vs Capacitive Load.” One method of improving capacitive load drive in the unity gain configuration is to insert a 10Ω to 20Ω resistor in series with the output, as shown in Figure 4. This significantly V+ reduces ringing with large capacitive loads. However, if I OVERLOAD there is a resistive load in parallel with the capacitive load, 10mA max OPAx343 VOUT RS creates a voltage divider. This introduces a dc error at the VIN output and slightly reduces output swing. This error may be 5kΩ insignificant. For instance, with R = 10kΩ and R = 20Ω, L S there is only about a 0.2% error at the output. FIGURE 3. Input Current Protection for Voltages Exceeding DRIVING A/D CONVERTERS the Supply Voltage.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
