ADS8860IDGSR集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADS8860IDGSR属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADS8860IDGSR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 ADS8860 is a 16-bit, 1-MSPS, single-ended

input, analog-to-digital converter (ADC). The device

operates with a 2.5-V to 5-V external reference,

offering a wide selection of signal ranges without

additional input signal scaling. The reference voltage

setting is independent of, and can exceed, the analog

supply voltage (AVDD).

The device offers an SPI-compatible serial interface

that also supports daisy-chain operation for

cascading multiple devices. An optional busyindicator

bit makes synchronizing with the digital host

easy.

The device supports unipolar single-ended analog

inputs in the range of –0.1 V to VREF + 0.1 V.

Device operation is optimized for very low-power

operation. Power consumption directly scales with

speed. This feature makes the ADS8860 excellent for

lower-speed applications.
