MCP3002-I/P屬于集成電路（IC）的模數(shù)轉(zhuǎn)換器（ADC）。由微芯科技股份有限公司制造生產(chǎn)的MCP3002-I/P模數(shù)轉(zhuǎn)換器（ADC）模數(shù)轉(zhuǎn)換器（ADC、A/D 或 A 轉(zhuǎn) D）對模擬信號進(jìn)行采樣，例如由麥克風(fēng)采集的聲音或傳感器的輸出，然后將其轉(zhuǎn)換為數(shù)字信號。一般來說，數(shù)字輸出是二進(jìn)制補(bǔ)碼二進(jìn)制數(shù)，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數(shù)轉(zhuǎn)換器可按照位數(shù)、采樣率、輸入數(shù)、接口、轉(zhuǎn)換器數(shù)和架構(gòu)（例如自適應(yīng)增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進(jìn)行選擇。

The MCP3002 is a successive approximation 10-bit

analog-to-digital (A/D) converter with on-board sample

and hold circuitry.

The MCP3002 is programmable to provide a single

pseudo-differential input pair or dual single-ended

inputs. Differential Nonlinearity (DNL) and Integral

Nonlinearity (INL) are both specified at ±1 LSB. Communication

with the device is done using a simple serial

interface compatible with the SPI protocol. The device

is capable of conversion rates of up to 200 ksps at 5V

and 75 ksps at 2.7V.

The MCP3002 operates over a broad voltage range,

2.7V to 5.5V. Low-current design permits operation with

a typical standby current of 5 nA and a typical active

current of 375 μA.

The MCP3002 is offered in 8-pin MSOP, PDIP, TSSOP

and 150 mil SOIC packages.
