AC-coupled circuits are often used for single supply operation to bring the input voltage into the inputrange of the amplifier. This circuit topology can be used in AC smoke detectors or in AC proximitysensors.

The first section of this 100-page book describes digital signal processing algorithms such as tone generation (including DTMF) voice compression/decompression (ADPCM) acoustic echo cancellation and caller-id used in telephony. The second section discusses each functional block of analog data and facsimile (fax) modem and provides descriptions of the processes within each block.

The OMAP™ device is built upon a dual-core architecture that consists of a TIARM925T MPU and a C55x™ DSP device. Both cores have access to internal memory via an internal memory interface (IMIF) as well as external memory via two external memory interfaces namely the EMIF Slow (EMIFS) and EMIF Fast (EMIFF). This application report focuses on the ARM side of the device and investigates the

This application report describes IEEE Std 1149.1 test-bus controller (TBC) SN74ACT8990 from Texas Instruments (TI). The first part explains the architecture and operation of the TBC; the second part uses examples to explain the programming procedure.TI is a trademark of Texas Instruments.

LP8501 Programming Considerations

This application report describes the MSP430 software to interface and use the TI DAC161P997 devices.The accompanying software contains a function library allowing quick prototyping of the DAC161P997setup and control. The software provided in this library is a starting point for developers wanting to get themost out of the MSP430 and the DAC161P997 devices.Source code discussed in this app

The TPS54160 is normally used as a buck voltage regulator. In these applications a lower dc voltage is derived from a higher input voltage. The output voltage is regulated by the internal current mode control circuitry to maintain a constant voltage over varying line and load conditions. The TPS54160 is not limited to use in the standard buck topology. This application report demonstrates

TVP5160 3D Noise Reduction Calibration Procedure

This application report contains implementation instructions for the DDR2 interface contained on the TMS320C6421 digital signal processor (DSP) device. The approach to specifying interface timing for the DDR2 interface is quite different than on previous devices.The previous approach specified device timing in terms of data sheet specifications and simulation models. The system designer was requ

TPS62130 Step-Down Converter with Input Overvoltage Protection

This bulletin describes three techniques for making a precision FVC using a VFC. The standard technique has high precision but high ripple or slow settling. Adding an output filter can improve the settling-time ripple trade-off but adds error. A third new technique can eliminate ripple from the FVC output and improve settling time by more than 1000/1 as compared to the conventional FVC. Moreove

Video Designs Using High-Speed Amplifiers

Normally the output voltage of a switching power supply is higher than the error amplifier reference and so a simple resistive divider between the output voltage and ground at the non-inverting input of the PWM error amplifier is all that is required to set the regulation voltage. However when the output voltage is less than the error amplifier reference voltage the feedback voltage must be div

The best of the monolithic voltage-to-frequency (V/F) converters have performance that is so good itequals or exceeds that of modular types. Some of these ICs can be designed into quite a variety ofcircuits because they are notably versatile. Along with versatility and high performance come theadvantages that are characteristic of all V/F converters including good linearity excellent resol
