... DD protocol. The device is capable of sample rates 2.7V DD 100 ksps at a clock rate of 1.6 MHz. The MCP3201 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 300 µA, respectively. The device is offered in 8-pin MSOP, PDIP, TSSOP and 150 mil SOIC packages ...
