Category: Digital Circuits / Display Circuits Views: 4369 Rank: 0 This application note provides layout suggestions to optimize the performance of the AD7843/AD7873. The AD7843/AD7873 are 12-bit successive-approximation ADCs with a synchronous serial interface and low onresistance switches for driving touch screens. The AD7843/AD7873 operate from a single 2.2 V to 5.25 V power supply and feature throughput rates greater than 125 kSPS.Both supplies to each of the AD7843 and AD7873 are analog supplies and should be connected directly together. Although various portable applications may have conflicting requirements with respect to power consumption, cost, size or weight, most should visit page.

Related circuits This circuit uses the CA3207 sequence driver and CA3208 segment latch-driver in combination to drive display devices of up to 14 segments with up to 14 characters of display. You are about to take part in one of the best microcomputer (microprocessor) projects you have seen. It uses a PIC16F84 micro and you will be shown how to program the chip to create quite amazing effects. It`s a simple project and you will be starting at the beginning of programming, so don`t... The circuit looks simple but this is very deceptive: many components interact, and while the circuit is capable of operation with widely varying component values, (useful during development) optimisation is required for each design to achieve the highest possible efficiencies. Heres a circuit to display the song number in an audio system for quick reference to songs. It also serves the purpose of an extra visual indicator in modern audio systems. AD7877 Touch Screen Controller and the Intel PXA250 The AN-738 Application Note details one way to connect an Analog Devices AD7877 touch screen controller to an Intel® PXA25x processor for use under a Windows® CE operating system. The user will be able to quickly develop a touch screen driver based on the example software accompanying this... They described using arrays of 64 or more LEDs as crude oscilloscopes and other interesting things. I decided I`d make one myself - a really big array, 256 LEDs arranged as 16 columns by 16 rows. In 1983, while I was in my final semester of electronics classes at Monterey Peninsula College, I... Flat-panel LCD monitors offer excellent image quality and more compact form factor than CRTshence, their steadily increasing popularity. Unfortunately, the complexity of their manufacturing process makes LCD monitors considerably more expensive than CRTs. The amplifier that drives VCOM, the... Embedded processor directly drives LCD Driving a bare LCD does not necessarily require specialized interface circuitry or peripherals. This Design Idea describes an alternative drive scheme, which you can easily implement using the general-purpose outputs of a microcontroller. Many embedded-system applications need to interact with a... Nokia N8 ? Screen Repair / Replace / Change a Broken LCD (AMOLED) or Touch Sc...
