产品信息
描述The ADS1203 is a delta-sigma () modulator with a 95dB dynamic range, operating from a single +5V supply. The differential inputs are ideal for direct connection to transducers or low-level signals. With the appropriate digital filter and modulator rate, the device can be used to achieve 16-bit analog-to-digital (A/D) conversion with no missing codes. An effective resolution of 14 bits or SNR of 85dB (typical) can be maintained with a digital filter bandwidth of 40kHz at a modulator rate of 10MHz. The ADS1203 is designed for use in medium- to high-resolution measurement applications including current measurements, smart transmitters, and industrial process control. The ADS1203 is available in TSSOP-8 and QFN-16 (3x3) packages.特性16-Bit Resolution 14-Bit Linearity ±250mV Input Range with Single +5V Supply 1% Internal Reference Voltage 1% Gain Error Flexible Serial Interface with Four Different Modes Implemented Twinned Binary Coding as Split-Phase or Manchester Coding for One-Line Interfacing Operating Temperature Range: 40°C to +125°C APPLICATIONS Motor Control Current Measurement Industrial Process Control Instrumentation Smart TransmittersAll trademarks are the property of their respective owners.

以ADS软件为例,射频电路设计的科学方法从20世纪80年代开始,射频微波电路技术的应用方向逐渐由传统波导同轴器件转移到微波平面PCB电路方面,微波平面电路设计一直是一项比较复杂的工作。现在的无线通信产品已经从早期的2G,逐步发展到3G、4G乃至5G。
