The Microchip Technology Inc. MCP3202 is a succes-

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

verter with on-board sample and hold circuitry. The

MCP3202 is programmable to provide a single

pseudo-differential input pair or dual single-ended

inputs. Differential Nonlinearity (DNL) is specified at

±1 LSB, and Integral Nonlinearity (INL) is offered in

±1 LSB (MCP3202-B) and ±2 LSB (MCP3202-C) ver-

sions. Communication with the device is done using a

simple serial interface compatible with the SPI protocol.

The device is capable of conversion rates of up to

100ksps at 5V and 50ksps at 2.7V. The MCP3202

device operates over a broad voltage range (2.7V -

5.5V). Low current design permits operation with typi-

cal standby and active currents of only 500nA and

375µA, respectively. The MCP3202 is offered in 8-pin

PDIP, TSSOP and 150mil SOIC packages.
