    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
  • Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)
    PDF, 227 Kb, 修订版: A, 档案已发布: Nov 10, 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

  • Interfacing the ADS7822 to synchronous serial port of the 80x51 Microcontroller
    PDF, 69 Kb, 档案已发布: Sep 27, 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
