Description
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
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.
