ADS8339IDGST集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8339IDGST属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8339IDGST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。

3 Description

The ADS8339 is a 16-bit, 250-kSPS, analog-to-digital

converter (ADC). The device operates with a 2.25-V to 5.5-V external reference. The device includes a

capacitor-based, successive-approximation register

SAR) ADC with an inherent sample-and-hold circuit.

The device includes a 25-MHz, SPI-compatible serial

interface. The interface is designed to support daisyChain

chaining or cascading of multiple devices.

Furthermore, a busy indicator makes synchronizing with the digital host easy. The unipolar, single-ended

input range for the device supports an input swing of

0 V to Vref.

The device is optimized for low-power operation and

power consumption scales directly with speed. This

feature makes the device attractive for lower speed applications. The ADS8339 is available in a VSSOP-

10 package.
