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.
