Application Notes
- Interfacing the TLV1544/1548 Analog Digital Converter to Digital ProcessorsPDF, 266 Kb, File published: Aug 1, 1997
This Application Report describes the hardware and software requirements for interfacing an A/D converter to a DSP and to a MCU. The 10-bit A/D converter TLV1544 (4 analog input channels) and the TLV1548 (8 analog input channels) from Texas Instruments have been used to develop such interface. Example software code has been written showing how to program the DSP and the MCU to control the A/D conv - Choosing an ADC and Op Amp for Minimum OffsetPDF, 72 Kb, File published: Oct 28, 1999
Designing a mixed-signal circuit containing analog and digital components can be a challenge to the development engineer. Requirements such as a low single-polarity supply voltage and a high degree of precision may conflict, and make the choice of components and the best circuit design difficult. This report discusses problems that arise in using operational amplifiers (op amps) for signal conditi - Determining Minimum Acquisition Times for SAR ADCs, part 1 (Rev. A)PDF, 227 Kb, Revision: A, File published: 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 - Determining Minimum Acquisition Times for SAR ADCs, part 2PDF, 215 Kb, File published: Mar 17, 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.
