T he AD7415 has three internal registers as shown in Fig-

ure 4. T wo are data registers and one is an address pointer

pointed to by the Address Pointer register when communi-

cating with it. T he T emperature Value register is the only

data register that is read only.

S-Grade T emperature Conversion Formula :-

(1) T emperature = +25°C + (ADC Code*/4)

(2) T emperature = (ADC Code* - 412)/4

T he Address Pointer Register is an 8-bit register which

stores an address that points to one of the two data regis-

ters. T he first byte of every serial write operation to the

AD7415 is the address of one of the data registers, which

is stored in the Address Pointer Register, and selects the

data register to which subsequent data bytes are written to

or read from. Only the two LSBs of this register are used

to select a data register.
