AD2S83AP集成电路（IC）的ADC/DAC-特殊用途规格书PDF中文资料

AD2S83AP属于集成电路（IC）的ADC/DAC-特殊用途。由亚德诺半导体技术有限公司制造生产的AD2S83APADC/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 AD2S83 is a monolithic 10-, 12-, 14-, or 16-bit tracking resolver-to-digital converter.

The converter allows users to select their own resolution and dynamic performance with external components. The converter allows users to select the resolution to be 10, 12, 14, or 16 bits and to track resolver signals rotating at up to 1040 revs per second (62,400 rpm) when set to 10-bit resolution.

The AD2S83 converts resolver format input signals into a parallel natural binary digital word using a ratiometric tracking conversion method. This ensures high noise immunity and tolerance of long leads allowing the converter to be located remote from the resolver.

The position output from the converter is presented via 3-state output pins which can be configured for operations with 8- or 16-bit bus. BYTE SELECT, ENABLE and INHIBIT pins ensure easy data transfer to 8- and 16-bit data bus, and outputs are provided to allow for cycle or pitch counting in external counters.

A precise analog signal proportional to velocity is also available and will replace a tachogenerator.

The AD2S83 operates over reference frequencies in the range 0 Hz to 20,000 Hz.
