MCP3002T屬于集成電路（IC）的模數轉換器（ADC）。由微芯科技股份有限公司制造生產的MCP3002T模數轉換器（ADC）模數轉換器（ADC、A/D 或 A 轉 D）對模擬信號進行采樣，例如由麥克風采集的聲音或傳感器的輸出，然后將其轉換為數字信號。一般來說，數字輸出是二進制補碼二進制數，與輸入成比例。輸入類型可能是差分、偽差分或單端輸入。模數轉換器可按照位數、采樣率、輸入數、接口、轉換器數和架構（例如自適應增量、雙斜率、折疊、流水線、SAR、三角積分、兩步式）進行選擇。

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.
