ADI公司的ADAQ4003是18位2MSPS取样μModule数据采集解决方案,具有可选输入范围的全差分ADC驱动器,包含基本的无源组件±0.005% iPassives匹配电阻阵列.器件具有宽输入共模电压范围,高共模抑制比和单端到差分转换以及信号链密度增加.保证18 位无失码,积分非线性为±3 ppm(典型值),SINAD为99 dB(G = 0.454),失调误差漂移为0.7 ppm/C(典型值)(G = 0.454),而增益误差漂移为±0.5 ppm/C(典型值).兼容串行接口 SPI-/QSPI-/MICROWIRE-/DSP;多功能逻辑接口电源,提供 1.8 V,2.5 V,3 V或5 V电压.采用小型7 mm × 7 mm0.80 mm 间距49球CSP_BGA封装.主要用在自动测试设备(ATE),机器自动化,过程控制,医疗设备和数字控制回路.本文介绍了ADAQ4003主要特性,功能框图,增益G为0.454,0.909,1.0和1.9的单端到差分配置图,以及G=0.454,0.909,1.0和1.9的差分配置图,评估板EVAL-ADAQ4003FMCZ主要特性,电路图和材料清单.

 

 The ADAQ4003 is a μModule® precision data acquisition (DAQ), signal chain solution that reduces the development cycle of a precision measurement system by transferring the signal chain design challenge of component selection, optimization, and layout from the designer to the device.

Using system-in-package (SIP) technology, the ADAQ4003 reduces end system component count by combining multiple common signal processing and conditioning blocks into a single device. These blocks include a high resolution 18-bit, 2 MSPS successive approximation register (SAR), analog-to-digital converter (ADC), a low noise, full..
