Although current-feedback amplifiers (CFAs) have been in use for quite some time there is a reluctance to view them in the same light as voltage-feedback amplifiers (VFAs). For instance the gain-bandwidth curve of VFAs has a parallel in a transimpedance-bandwidth curve for CFAs. This parameter can be used to determine the closed-loop behavior of the CFA in same way that GBW can for the VFA. Not

The signal-to-noise ratio and bandwidth of the combination of the ACF2101 dual switched integrator and a low-level input current is exceptional when compared to the performance of a classical transimpedance amplifier. To further improve the ACF2101 signal-to-noise ratio a resistor can be added in series with the input sensor.

With XDM1.0 the decoder does not have separate reference and display buffers. The reference buffers of the decoder are used for display as well. This helps in reducing the overall DDR utilization and DDR b/w.However this new arrangement changes the overall buffer management of the application. Now the application needs to manage the display and reference buffers using the new XDM 1.0 APIs. Thi

In today?s competitive computing and networking industry any equipment downtime due to component interconnects or bus failures impedes communication hinders productivity and hampers financial growth. In recognizing this increasingly costly unplanned downtime the industry introduced live-insertion technology to minimize the impact of any such failures. The live-insertion feature enables a networ

This document describes the GSM half-rate voice coding implementation on the TMS320C62xx processor (also called the vocoder). It discusses the system requirements and gives two levels of detail for the subroutines. The first level is designed for programmers who want to use the code in a basic GSM architecture. The second level is for programmers who want to see how the code is implemented for mod

This software demonstration combines real-time D1 Joint Photographic Experts Group (JPEG) encoding and decoding of images on the DM642 Evaluation Module (EVM) with networking functionality.

The JPEG standard pertains to compression of still images. Performing JPEG compression at the rate of 30 frames per second in isolation as individual images is known as motion JPEG (MJPEG). This demonstrat

This application report describes two methods for implementing a digital sine-wave generator using the TMS320C2xx: the use of a direct look-up table with linear interpolation, and the use of mathemati

The ADS7843 is a 12-bit sampling analog-to-digital converter (ADC) used to drive 4-wire touch-screens to serial interfaces by ratiometrically converting two differential input signals. The ADS7843 also produces an accurate output with the first conversion cycle once powered up.

This application report analyzes a simple method for calculating minimum acquisition times for successive-approximation register analog-to-digital converters (SAR ADCs). The input structure of the ADC

Bipolar linear integrated circuits have been with us for years in the form of PWM and PFC controllers supervisory circuits and other circuits. Since these devices have traditionally used relatively high-voltage (35V) bipolar processes powering was not a concern. In addition many of these ICs contained high-current protection zeners to keep higher voltages from damaging the devices. With a numb

The Texas Instruments (TI)(tm) TMS320F240 digital signal processor (DSP) controller contains a hardware deadband unit that automatically generates a deadband in the six PWM (pulse width modulation) signals from the full compare unit. This document describes how the DSP can use the other six available PWM signals to drive a second three-phase inverter with deadband.

The THS8133, THS8134, THS8135, and the THS8200 devices are part of a family of chips for graphics and video applications, which contain triple DACs that operate from 80 MSPS to 240 MSPS. For televisio

TPS92641 Brightness Turbo TPS92641 Application Note

This application note discusses programming of the LM628/LM629 motion control processors.

This application report discusses the process of replacing the CLC001 cable driver with the LMH0001 cable driver.

Generating a high-frequency system clock Fs (128fs to 768fs) from a low-frequency sampling clock fs (10 kHz to 200 kHz) is challenging while attempting to maintain low phase jitter. A traditional phase-lock loop (PLL) can do the frequency translation but the added phase jitter prevents the generated system clock signal from effectively driving high-performance audio data converters. This applica

There is a lot of confusion about how to operate a fully differential op amp from a single power supply. This application note describes how to select the correct dc operating point of a fully differential op amp.
