- Remove the DC Portion of Signals with the ADS7817PDF, 55 Kb, Datei veröffentlicht: Sep 27, 2000
Unwanted portions of a signal, such as a DC pedestal, can be difficult to reject in a single supply circuit. A DC pedestal voltage most typically appears at the output of an operational amplifier with a small signal riding on top of it. This pedestal voltage is required in the analog domain to insure that the small signal that contains the pertinent information never falls below the ground potenti - Short Cycling the 8-Pin ADS78xx FamilyPDF, 65 Kb, Datei veröffentlicht: Sep 27, 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 Kb, Datei veröffentlicht: 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 - High-Voltage Signal Conditioning for Differential ADCsPDF, 125 Kb, Datei veröffentlicht: Jun 14, 2004
Analog designers are frequently required to convert high-voltage signals to levels acceptable to low-voltage data converters with differential inputs. This paper describes solutions for this common task using modern amplifiers and typical power supplies. Three examples of conditioning В±10V bipolar signals for low-voltage analog-to-digital converters (ADCs) are shown: a single-supply design, - Coding Schemes Used with Data Converters (Rev.

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.
