DESCRIPTION

The Microchip Technology Inc. MCP3201 is a succes-

sive approximation 12-bit Analog-to-Digital (A/D) Con-

verter with on-board sample and hold circuitry. The

device provides a single pseudo-differential input. Dif-

ferential Nonlinearity (DNL) is specified at ±1 LSB, and

Integral Nonlinearity (INL) is offered in ±1 LSB

(MCP3201-B) and ±2 LSB (MCP3201-C) versions.

Communication with the device is done using a simple

serial interface compatible with the SPI protocol. The

device is capable of sample rates of up to 100ksps at a

clock rate of 1.6MHz. The MCP3201 operates over a

broad voltage range (2.7V - 5.5V). Low current design

permits operation with typical standby and active cur-

rents of only 500nA and 300µA, respectively. The

device is offered in 8-pin PDIP, TSSOP and 150mil

SOIC packages.
