Application Notes
- Interfacing the ADS7822 to the TMS3420C5402 DSPPDF, 111 Кб, Файл опубликован: 14 ноя 2000
This report presents a method for interfacing the ADS7822 12-bit SAR analog-to-digital converter to the TMS320C5402 DSP. - Short Cycling the 8-Pin ADS78xx FamilyPDF, 65 Кб, Файл опубликован: 27 сен 2000
The most recent 8-pin, 12-bit A/D converters that Burr-Brown has introduced to the market are advertised as high speed, micropower, low priced sampling SAR devices. During product development and the initial introduction period, the engineering effort was placed on optimizing the combination of 12 bits with high speed, low power and low cost. Burr-Brown Applications has revisited these converters - Interfacing the ADS7822 to synchronous serial port of the 80x51 MicrocontrollerPDF, 69 Кб, Файл опубликован: 27 сен 2000
Analog-to-digital converters can be controlled by a normal I/O port or with the synchronous serial port of the 80x51 microcontrollers. The synchronous serial port is more efficient, however, there are some pitfalls to be aware of when configuring the 8-pin A/D converters (ADS1286, ADS7816, ADS7817 and ADS7822) from Burr-Brown. This application bulletin describes how to get around these pitfalls an - Interfacing the MSOP8EVM to TMS320C5x ProcessorsPDF, 225 Кб, Файл опубликован: 28 апр 2004
This application note presents a method for interfacing the modular MSOP8 evaluation module (EVM), an EVM for single-channel, low-power, 8- to 16-bit serial analog-to-digital converters, to the TMS320C5x series DSKs using a 5-6K interface board. The software developed provides compile options to choose the proper data formatting for the ADS7816, ADS7817, ADS7818, ADS7822, ADS7826, ADS7827, ADS7829 - Interfacing the MSOP8EVM to TMS320C6x ProcessorsPDF, 219 Кб, Файл опубликован: 2 дек 2003
The modular MSOP8EVM is an evaluation module for single-channel, low-power, 8 to 16-bit serial analog-to-digital converters.

The soft - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Кб, Версия: A, Файл опубликован: 10 ноя 2010
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 is examined along with the driving circuit. The voltage on the sampling capacitor is then determined for the case when a step function is applied to the input of the driving circuit. Three different - Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 215 Кб, Файл опубликован: 17 мар 2011
The input structure circuit of a successive-approximation register analog-to-digital converter (SAR ADC) incombination with the driving circuit forms a transfer function that can be used to determine minimum acquisition times for different types of applied input signals.
