凌力尔特公司推出24位、16通道增量累加模数转换器(ADC) LTC2498。该器件具有前端设计,可直接数字化多种传感器信号。LTC2498的Easy Drive~(TM)设计使得平均差分输入电流为零．允许不采用内部缓冲器就可测量高阻抗输入源。这个获得专利的采样方案简化了前端信号调节电路的设计,允许使用电桥、RTD、热电耦和其它高阻抗传感器直接驱动该ADC。轨至轨输入信号可以直接数字化．同时保持了卓越的DC准
Linear Technology introduces the LTC2498, a 24-bit, 16-channel delta-sigma-delta ADC. The device has a front-end design that directly digitizes multiple sensor signals. The LTC2498’s Easy Drive ™ design allows for an average differential input current of zero. Allows high-impedance input sources to be measured without an internal buffer. This patented sampling scheme simplifies the design of the front-end signal conditioning circuitry, allowing the ADC to be directly driven using bridges, RTDs, thermocouples and other high-impedance sensors. The rail-to-rail input signal can be directly digitized. At the same time maintain the excellent DC standards
