Description
The 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 operates over a broad voltage range,
2.7V to 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.

Note 1:
This parameter is established by characterization and not 100% tested.
2:
Because the sample cap will eventually lose charge, effective clock rates below 10 kHz can affect linearity performance,
especially at elevated temperatures. See
Section 6.2 “Maintaining Minimum Clock Speed”
for more information.
