A number of instrumentation applications can benefit from the use of logarithmic or exponential signalprocessing techniques. The design and use of logarithmic/exponential circuits are often associated withinvolved temperature compensation requirements and difficult to stabilize feedback loops. For theseconsiderations and others designers tend to avoid these circuits. Hybrid and modularlog

TMS320C6713 to TMS320C672x Migration Guide Application Report

This report describes various methods for connecting the ADS7842 to Texas Instruments TMS320C5400 DSP and TMS320C6000 DSP platforms. The ADS7842 is a 4-channel 12-bit analog-to-digital converter (ADC) with a maximum sampling rate of 200 kHz.

Receipt of data from a TIA/EIA-422 line driver can be accomplished by using a TIA/EIA-644 line receiver with the addition of an attenuator circuit. This technique gives the user a very high-speed low-power 422 receiver.If ground noise between the transmitter and receiver is not a concern (less than +/-1 V) a resistor divider circuit can be placed in front of the LVDS receiver to attenuate th

Removal of lead (Pb) from finished integrated-circuit(IC) packages as well as IC package assembly and printed circuit board(PCB) assembly operations is an ongoing effort by many electronics manufacturers.Toward this end the semiconductor industry is converting to nickel/palladium (Ni/Pd)-finished leadframes in the assembly of integrated circuits. This technology eliminates Pb from the IC pa

This application report describes how to use the multichannel buffered serial port (McBSP) in the Texas Instruments TMS320C6000™ digital signal processor (DSP) for data packing. Data packing involves moving either multiple successive 8-bit elements to/from the McBSP as a single 16/24/32-bit element or multiple successive 16-bit words to/from the McBSP as a single 32-bit word.

The McBSP

This document provides some guidelines for selecting decoupling capacitors for TMS320C3x devices.

The UCC2722x contains an internal 6.5-V regulator from which the gate drive voltages for the high and low-side MOSFETs of a synchronous buck power stage are derived. In some instances it may be desirable to drive the MOSFET gates with a voltage other than 6.5 V. The output driver stage of the UCC2722x has an absolute maximum voltage rating of 10 V. However it is still possible to bypass the inter
