Typically 0. In addition, the TLC offers a bias-select mode that allows the user to select the best combination of power dissipation and ac performance for a particular application.
These devices use Texas Instruments silicon-gate LinCMOS technology, which provides offset voltage stability far exceeding the stability available with conventional metal-gate processes. Add R suffix to the device type e. 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.
Products conform to specifications per the terms of Texas Instruments standard warranty. Production processing does not necessarily include testing of all parameters. The extremely high input impedance and low bias currents, in conjunction with good common-mode rejection and supply voltage rejection, make these devices a good choice for new state-of-the-art designs as well as for upgrading existing designs.
In general, many features associated with bipolar technology are available in LinCMOS operational amplifiers, without the power penalties of bipolar technology. General applications such as transducer interfacing, analog calculations, amplifier blocks, active filters, and signal buffering are all easily designed with the TLC The devices also exhibit low-voltage single-supply operation, making them ideally suited for remote and inaccessible battery-powered applications.
The common-mode input voltage range includes the negative rail. A wide range of packaging options is available, including small-outline and chip-carrier versions for high-density system applications. The TLC offers a bias-select feature that allows the user to select any one of three bias levels depending on the level of performance desired. The tradeoffs between bias levels involve ac performance and power dissipation see Table 1. Table 1. For medium-bias applications, it is recommended that the bias select pin be connected to the midpoint between the supply rails.
This procedure is simple in split-supply applications, since this point is ground. In single-supply applications, the medium-bias mode necessitates using a voltage divider as indicated in Figure 1. The use of large-value resistors in the voltage divider reduces the current drain of the divider from the supply line. However, large-value resistors used in conjunction with a large-value capacitor require significant time to charge up to the supply midpoint after the supply is switched on.
A voltage other than the midpoint can be used it is within the voltages specified in Figure 1. In the high-bias mode, the TLC series features low offset voltage drift, high input impedance, and low noise. Speed in this mode approaches that of BiFET devices but at only a fraction of the power dissipation.
Unity-gain bandwidth is typically greater than 1 MHz. The TLC in the medium-bias mode features low offset voltage drift, high input impedance, and low noise. Speed in this mode is similar to general-purpose bipolar devices but power dissipation is only a fraction of that consumed by bipolar devices.
