<article><h2>Data Acquisition - Analog to Digital Converters (ADC)</h2><p><strong>The AD7777ARZ</strong> is a high-performance, low power, low cost, multi-function, 4-channel analog-to-digital converter (ADC) used in many electronic and industrial applications. This converter features excellent signal-to-noise (SNR) performance, high resolution, and a low input capacitance. It is capable of simultaneous analog-to-digital conversion of 4 analog inputs, with each input channel having its own dedicated Analog-to-Digital Converter (ADC). </p><p>The AD7777ARZ is well-suited for a variety of hostile industrial environmental conditions, such as vibration, temperature extremes, humidity, and dust, making it ideal for use in a variety of industries, including medical, automotive, power electronics, aerospace, and industrial automation. Its low power consumption and wide input common-mode range make it suitable for use in battery-powered systems, and its single supply operation eliminates the need for a dedicated dual supply. Additional features such as a selectable input offset, low ripple and low noise, programmable input terminal protection, and conversion speed make the AD7777ARZ a great choice for many applications.</p><h3>Application Field</h3><p>The AD7777ARZ can be used in a variety of applications including:</p><ul><li>Medical imaging systems</li><li>Semiconductor testing</li><li>Industrial control systems</li><li>HVAC, automotive and power electronics</li><li>High voltage testing</li><li>Mass spectrometry</li><li>Data acquisition</li><li>Motor speed and position control</li></ul><p>The AD7777ARZ is also ideal for use in low-power, battery-powered equipment where power consumption is critical. Its low input capacitance and low power consumption make it suited for many mobile applications such as communications, automotive, and point-of-sale systems. </p><h3>Working Principle</h3><p>The AD7777ARZ is a 4-channel ADC which provides simultaneous analog-to-digital conversion of 4 analog inputs. Each input channel has its own dedicated ADC with a 12-bit resolution and a full-scale range of 0 to +4 volts.</p><p>The AD7777ARZ is powered by a single 4.75 to 5.25 volt supply, and can operate from -40&deg;C to +85&deg;C. It has an input range of 0 to +4 volts and can convert 16,000 samples per second. It also has a selectable input offset, low ripple and low noise, and programmable input terminal protection.</p><p>The AD7777ARZ is designed to be easily interfaced to microcontrollers, FPGA’s, and other digital IC’s. It provides 8-bit digital output in either CMOS or LVDS format, depending on the configuration.</p></article>
