MCP3202T-BI/SN

MCP3202T-BI/SN is a 2.7V dual channel 12bit A/D converter with SPI serial interface. It is a successive approximation 12bit analogue-to-digital (A/D) converter with on-board sample and hold circuitry. It is programmable to provide a single pseudo-differential input pair or dual single-ended inputs. Communication with the device is done using a simple serial interface compatible with the SPI protocol. This device is capable of conversion rates of up to 100ksps at 5V and 50 ksps at 2.7V. It operates over a broad voltage range, 2.7V to 5.5V. Low-current design permits operation with typical standby and active currents of only 500nA and 375µA, respectively. Application includes sensor interface, process control, data acquisition, battery operated systems.
