Type: AI = Analog Input; DI = Digital Input; AO = Analog Output; P = Power.
Electrical test are performed at wafer probe to the limits shown. Due to variations in assembly methods and normal
yield loss, yield after packaging is not guaranteed for standard product dice.
Limits extrapolated from testing of individual bit errors.
Die offers latch control pad. Edge triggered latches become level triggered when latch control and clock pads are high.
Die substrate is connected to V
