What is the minimum startup VDD voltage for the signal conditioner?
A. The signal conditioner will start with VDD as low as 2.5V. However, the operation is guaranteed with a minimum VDD of 4.5V. See Application Note 3733, Startup Requirements for the MAX1452/MAX1455 Signal Conditioners. • Q. What is the factory setting for the flash memory content? A. The signal conditioner is shipped with the flash memory ERASED (0xFFFF in all memory locations), except for the Control and Configuration registers. The Control register content is 0xFF00 to place the part in digital mode; the Configuration register content is xxx0000011111111b (or X0FFhex). The xxx (3 MSBs) are the oscillator trim setting. • Q. Is the signal conditioner’s default operating mode digital or analog? A. The signal conditioner normally ships in digital mode from the factory, i.e. the Control register is set to 0xFF00. • Q. What is the factory setting of the Configuration register? A. The Configuration register normally contains xxx0000011111111b (or X0FFhex). The xxx (3 MSBs) are the oscillat
