Description

The Microchip Technology Inc. MCP3202 is a

successive approximation 12-bit Analog-to-Digital

(A/D) Converter 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) versions. 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 100 ksps at 5V and 50 ksps

at 2.7V. The MCP3202 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 375 µA, respectively. The

MCP3202 is offered in 8-pin MSOP, PDIP, TSSOP and

150 mil SOIC packages.
