<p>PURPOSE: To obtain an integrated circuit for measuring a physiological signal which responds appropriately to signal input by controlling a function of a signal processing channel in a digital way. CONSTITUTION: An integrated circuit has multiple analog signal processing channels with multiple functions controllable in digital way and a digital controlling means for controlling these multiple functions. The digital controlling means is equipped with a digital controlling signal input 366 containing command input bits and data input bits; a command complexing means 1906 for the command input bits to produce multiple resistor selecting signals; and multiple controlling output means with multiple controlling bits for controlling functions respectively. Furthermore, there are arranged multiple controlling resistor means 1912, 1914, 1916, 1918 for storing the data input bits after selected by the resistor selecting signal. Thus, there is obtained the integrated circuit by which the physiological signal corresponding appropriately to signal input can be measured.</p> |
