Question The IBIS model provided on our website (www.analog.com/ad5142) is designed only for LFCSP package. Could you please provided an IBIS file for DSO package – 16 ld TSSOP? Answer LFCSP and TSSOP have same pinout, you can use the same IBIS file. You just need to reorder manually the pins to fit for the TSSOP package.

AD5142- Writing to EEPROM

Question I try to set the value to RDAC1 and RDAC2, but only RDAC1 is successful and Iuse the same code (I send command 11), changing only A0 and A1, in particular0b00 for RDAC1 and 0b01 for RDAC2. Unfortunately only RDAC1 is correctly set and RDAC2 remain to 0x128. Answer This looks like an issue with read command. Please note that this will changeif the "Linear Gain Setting mode is used". To write to the EEPROM- Use command 11 from the table16 and consider the channel column. A1 and A0 are the address bits where,a. A1=0 and A0=0 , to write to RDAC1b. A1=0 and A0=0, to write to RDAC2
