DN303 -- Cleanup of Installed PC Tools

This application report discusses the power consumption of the Texas Instruments C6747/45/43. Power consumption on the C6747/45/43 devices are highly application-dependent so a spreadsheet is provided to model power consumption for a user's application. To obtain good results from the spreadsheet realistic usage parameters must be entered. The low-core voltage and other power design optimization

Understanding the input and output limitations of an instrumentation amplifier (IA) is important in interfacing a resistive bridge sensor to the PGA900. Adjusting the common mode voltage of the input

This application report describes a design example that uses fast TPS5625 hysteretic controller and low-cost TL5001A PWM controller installed in SLVP105 and SLVP101 EVMs for a TMS320C6201 DSP application. This design converts 5 V to 2.5 V at 8 A and 3.3 V at 3 A for high-current DSP applications.

This application note addresses a method to OR the high side of the power source as well as the low side using N-channel MOSFETs, thus replacing diodes D1 and D2 with more efficient MOSFETs in the hig

This report develops the transfer function and loop gain of nonideal operational-amplifier (op-amp) circuits so the ac errors of the op amp can be analyzed. It describes inverting noninverting and differential op-amp circuits.

1N to 2N Conversion

The CDCLVC11xx buffer family from Texas Instruments has a nominal voltage supply of 2.5 V and 3.3 V. With the simple employment of an external RC network this family of devices can handle incoming signals whose voltage levels go up to 1.8 V. This application report explains how to implement this network and dimension its discrete components without impacting the specifications of additive ji

The network requirements of many countries require the analog subscriber line circuit (SLIC) to terminate the subscriber line with an impedance for voiceband frequencies which is complex rather than resistive (e.g. 600 Ohms). This requires that the physical resistance that is situated between the SLIC and the subscriber line comprised of protection and/or sensing resistors and the output resist

The UCC3858 provides all functions necessary for active power-factor-corrected preregulators that require high efficiency for low-power operation. This design note describes the UCC3858 demonstration

Accurate performance of the bq27x10 gas gauge requires that the 10 user-configurable EEPROM coefficients be programmed to values that reflect the appropriate host system and battery characteristics. This application report provides the basis for determining the optimal EEPROM coefficients from the host system operational characteristics and battery characterization data. Appendix A specifically ad

Noise Analysis in Operational Amplifier Circuits

Presented in this application note is the implementation of A-law and mu-law companding routines for the TMS320C54x. Theoretical material regarding companding and speech signals is provided first followed by thorough explanations of the algorithms. Finally the code is benchmarked in terms of its speed and memory requirements.

The precision current source and sink are based on the new REF102 10.0V voltage reference. With 2.5ppm/°C V_OUT drift and better than 5ppm/1000hrs long-term stability this buried-zener-based voltage reference offers the best performance available from a single-chip voltage reference today. The REF200 uses a band-gap type reference to allow low-voltage two-terminal operation. This m
