The MCP3002 is a successive approximation 10-bit
analog-to-digital (A/D) converter with on-board sample
and hold circuitry.
The MCP3002 is programmable to provide a single
pseudo-differential input pair or dual single-ended
inputs. Differential Nonlinearity (DNL) and Integral
Nonlinearity (INL) are both specified at ±1 LSB. 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 200 ksps at 5V
and 75 ksps at 2.7V.
The MCP3002 operates over a broad voltage range,
2.7V to 5.5V. Low-current design permits operation with
a typical standby current of 5 nA and a typical active
current of 375 μA.
The MCP3002 is offered in 8-pin MSOP, PDIP, TSSOP
and 150 mil SOIC packages.
