Get low-noise, low-ripple, high-PSRR power with the TPS717xx
Texas InstrumentsWhile highly efficient switching power supplies are commonly used for long battery life in portable end equipment such as mobile phones and PDAs, the internal circuitry of some of these devices is sensitive to noise and therefore does not operate properly when powered from a switching power supply with output ripple. Audio circuitry, PLLs, RF transceivers, and DACs are just a few examples of such circuits. Linear regulators are ideal for powering these circuits.
TMS320C55x Self-check Program: Version 1.0
Texas InstrumentsThe TMS320C55x?(C55x?) self-check program verifies the operation of DSP devices in the C55x generation by checking for proper operation of the CPU core and internal RAM. On-chip peripherals are not tested since doing so would be target system dependent. It is important to note that this program only provides a confidence check. It is not as comprehensive as the tests done at production which thor
LB-11 The LM110 - An Improved IC Voltage Follower
Texas InstrumentsThere are quite a few applications where op amps are used as voltage followers. These include sample and hold circuits and active filters as well as general purpose buffers for transducers or other high-impedance signal sources. The general usefullness of such an amplifier is particularly enhanced if it is both fast and has a low input bias current. High speed permits including the buffer in the signal path or within a feedback loop without significantly affecting response or stability. Low input current prevents loading of high impedance sources, which is the reason for using a buffer in the first place.

TMS320C6000 C Compiler: C Implementation of Intrinsics
Texas InstrumentsThe first optimization step that you can perform on C source code for the TMS320C62xx is to use intrinsic operators. Intrinsics are used like functions and produce assembly language statements that would otherwise be inexpressible in C. The problem is that once you have performed the first optimization step your C source code is no longer ANSI C compatible. The code proposed within this appli
