ADS8341集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8341属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8341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 ADS8341 is a 4-channel, 16-bit sampling Analog-to-

Digital (A/D) converter with a synchronous serial interface.

Typical power dissipation is 8mW at a 100kHz throughput

rate and a +5V supply. The reference voltage (VREF) can be

varied between 500mV and VCC, providing a corresponding

input voltage range of 0V to VREF. The device includes a

shutdown mode that reduces power dissipation to under

15μW. The ADS8341 is tested down to 2.7V operation.

Low power, high speed, and an onboard multiplexer make

the ADS8341 ideal for battery-operated systems such as

personal digital assistants, portable multi-channel data loggers,

and measurement equipment. The serial interface also

provides low-cost isolation for remote data acquisition. The

ADS8341 is available in an SSOP-16 package and is ensured

over the –40°C to +85°C temperature range.
