ADC081S101集成电路（IC）的模数转换器（ADC）规格书PDF中文资料

ADC081S101属于集成电路（IC）的模数转换器（ADC）。由德州仪器制造生产的ADC081S101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 ADC081S051 is a low-power, single channel

CMOS 8-bit analog-to-digital converter with a high- speed serial interface. Unlike the conventional

practice of specifying performance at a single sample

rate only, the ADC081S051 is fully specified over a

sample rate range of 200 ksps to 500 ksps. The converter is based on a successive-approximation

register architecture with an internal track-and-hold

circuit.

The output serial data is straight binary, and is

compatible with several standards, such as SPI™,

QSPI™, MICROWIRE, and many common DSP

serial interfaces.

The ADC081S051 operates with a single supply that

can range from +2.7V to +5.25V. Normal power

consumption using a +3.6V or +5.25V supply is 1.6

mW and 8.5 mW, respectively. The power-down

feature reduces the power consumption to as low as

2.6 μW using a +5.25V supply.

The ADC081S051 is packaged in 6-lead WSON and

SOT-23 packages. Operation over the industrial

temperature range of −40°C to +85°C is ensured.
