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.
