Description
The Microchip Technology Inc. MCP3201 device is a
successive approximation 12-bit Analog-to-Digital
(A/D) Converter with on-board sample and hold
circuitry. The device provides a single pseudo-differen-
tial input. Differential 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
100 ksps at a clock rate of 1.6 MHz. The MCP3201
device operates over a broad voltage range (2.7V-
5.5V). Low-current design permits operation with
typical standby and active currents of only 500 nA and
300 A, respectively. The device is offered in 8-pin
MSOP, PDIP, TSSOP and 150 mil SOIC packages.
