Một DAC 16-bit có thể được xây dựng bằng cách sử dụng ba chiết áp kỹ thuật số 8-bit và ba bộ khuếch đại để cung cấp 65.536 điện áp đầu ra khác nhau. Nếu VDD là 5V trong hệ thống này, độ phân giải và kích thước LSB DAC này là 76,3 mV. Mạch này có thể được sử dụng trong hai chế độ hoạt động cơ bản. | Analog and Interface Microchip Analog and Interface Guide - Volume 1 A Compilation of Technical Articles and Design Notes Analog and Interface Guide - Volume 1 Table of Contents Contents An Intuitive Approach To Mixed Signal Layout Part 1 - The Art Of Laying Out Two Layer Boards.1 Part 2 - Could It Be Possible That Analog Layout Differs From Digital Layout Techniques .5 Part 3 - Where the Board and Component Parasitics Can Do The Most Damage.8 Part 4 - Layout Techniques To Use As The ADC Accuracy And Resolution Increases.11 Part 5 - The Trouble With Troubleshooting Your Layout Without The Right Tools.13 Part 6 - Layout Tricks For A 12-Bit Sensing System.15 Miscellaneous Keeping Power Hungry Circuits Under Thermal Control.19 Instrumentation Electronics At A Juncture.21 Select The Right Operational Amplifier For Your Filtering Circuits.23 Ease Into The Flexible CANbus Network.25 All articles presented here are authored by Bonnie C. Baker Mixed Signal Analog Applications Manager Microchip Technology Inc. Analog and Interface Guide - Volume 1 An Intuitive Approach to Mixed Signal Layout - Part 1 The Art of Laying Out Two Layer Boards In this highly competitive battery-powered marketplace cost objective usually dictates that a designer uses two layer boards in the design. Although the multi-layer board 4- 6- and 8-layers allows the designer to build cleaner solutions in terms of size noise and performance financial pressures force the engineer to rethink his layout strategies with the two-layer board in mind. In this article we will discuss the use or misuse of auto routing the concept of current return paths with and without ground planes and recommendations for component placement where two layer boards are concerned. Pay Now Or Pay Later With The Auto Router And Analog Circuits It is tempting to use the auto router when designing a printed circuit board PCB . More often than not a purely digital board especially if the signals are relatively slow and the circuit .
