Control Logic

The Microchip Technology Inc. MCP3001 is a succes-

sive approximation 10-bit A/D converter (ADC) with on-

board sample and hold circuitry. The device provides a

single pseudo-differential input. Differential Nonlinear-

ity (DNL) and Integral Nonlinearity (INL) are both spec-

ified at ±1 LSB max. Communication with the device is

done using a simple serial interface compatible with the

SPI protocol. The device is capable of sample rates up

to 200 ksps at a clock rate of 2.8 MHz. The MCP3001

operates over a broad voltage range (2.7V - 5.5V).

Low current design permits operation with a typical

standby current of only 5 nA and a typical active current

of 400 µA. The device is offered in 8-pin PDIP, MSOP,

TSSOP and 150 mil SOIC packages.
