TC534CKW集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

TC534CKW属于集成电路（IC）的ADC/DAC-特殊用途。由美国微芯科技公司制造生产的TC534CKWADC/DAC - 特殊用途该产品族中的产品可用于模拟和数字表示的信息转换，适用于特定用例，或集成了通用数据转换器中不常见的其他功能。例如针对超声或汽车雷达应用集成了低噪声放大器和可变增益级的器件、注重音频和视频的产品、在段码式显示器上集成显示测量值功能的器件、集成输入输出电气隔离的器件等。

GENERAL DESCRIPTION

The TC530/534 are serial analog data acquisition subsystems ideal for high precision measurements (up to 17 bits plus sign). The TC530 consists of a dual slope integrating A/D converter, negative power supply generator and 3 wire serial interface port. The TC534 is identical to the TC530, but adds a four channel differential input multiplexer. Key A/D converter operating parameters (Auto Zero and Integration time) are programmable, allowing the user to trade-off conversion time for resolution.

The TC530/534 timebase can be derived from an external crystal of 2MHz (max), or from an external frequency source. The TC530/534 requires a single 5V power supply and features a – 5V, 10mA output which can be used to supply negative bias to other components in the system.
