ADS7862Y集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS7862Y属于集成电路（IC）的模数转换器（ADC）。由美国德州仪器公司制造生产的ADS7862Y模数转换器（ADC）模数转换器（ADC、A/D 或 A 转 D）对模拟信号进行采样，例如由麦克风采集的声音或传感器的输出，然后将其转换为数字信号。一般来说，数字输出是二进制补码二进制数，与输入成比例。输入类型可能是差分、伪差分或单端输入。模数转换器可按照位数、采样率、输入数、接口、转换器数和架构（例如自适应增量、双斜率、折叠、流水线、SAR、三角积分、两步式）进行选择。

DESCRIPTION

The ADS7862 is a dual 12-bit, 500kHz analog-to-digital

converter (A/D) with 4 fully differential input channels grouped

into two pairs for high speed simultaneous signal acquisition.

Inputs to the sample-and-hold amplifiers are fully differential

and are maintained differential to the input of the A/D converter.

This provides excellent common-mode rejection of

80dB at 50kHz, which is important in high noise environments.

The ADS7862 offers parallel interface and control inputs to

minimize software overhead. The output data for each channel

is available as a 12-bit word. The ADS7862 is offered in an

TQFP-32 package and is fully specified over the –40°C to

+85°C operating range.
