Description

The Microchip Technology Inc. MCP3002 is a succes-

sive approximation 10-bit Analog-to-Digital (A/D) Con-

verter with on-board sample and hold circuitry. The

MCP3002 is programmable to provide a single pseudo-

differential input pair or dual single-ended inputs. Differ-

ential 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 device operates over a broad

voltage range (2.7V - 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.
