ADS5231IPAGT集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS5231IPAGT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ADS5231IPAGT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 ADS5231 is a dual, high-speed, high dynamic

range, 12-bit pipelined analog-to-digital converter

(ADC). This converter includes a high-bandwidth

sample-and-hold amplifier that gives excellent spurious performance up to and beyond the Nyquist

rate. The differential nature of the sample-and-hold

amplifier and ADC circuitry minimizes even-order

harmonics and gives excellent common-mode noise

immunity.

The ADS5231 provides for setting the full-scale

range of the converter without any external reference

circuitry. The internal reference can be disabled,

allowing low-drive, external references to be used for

improved tracking in multichannel systems.

The ADS5231 provides an over-range indicator flag

to indicate an input signal that exceeds the full-scale

input range of the converter. This flag can be used to

reduce the gain of front-end gain control circuitry.

There is also an output enable pin to allow for

multiplexing and testing on a printed circuit board

(PCB).

The ADS5231 employs digital error correction

techniques to provide excellent differential linearity

for demanding imaging applications. The ADS5231 is

available in a TQFP-64 package.
