Are there any programming examples available for the MAX1464?

Yes. Example codes are part of the MAX1464 EV kit software available on the Maxim website. Assembly language examples include 2nd-order compensation algorithm, an LED-blinking program, and a typical loop…
Can I use the Control program in both 3-wire and 4-wire communication for the MAX1464?

Yes, you can use it for both.
Can I use the MAX1464 hardware debugger program in both 3-wire and 4-wire communication?

Yes.
Can I use the MAX1464 hardware debugger program in both 3-wire and 4-wire communication?

Yes.
Can Partition-1 (user portion) of the MAX1464 flash memory be accessed by the CPU program?

No. Partition-1 can only be accessed through the SPI interface. Partition-1 cannot be used to control the MAX1464 operation.
Can the MAX1464 be used to measure the RTDs or K-type thermocouples?

Yes. The user must always ensure that the voltage levels at INM and INP are above VSS and below VDD. If extra gain is necessary, the op amps in the DOP can be used to implement an analog gain stage, which…

Can the op amps on the MAX1464 be used as uncommitted op amps?

Yes. There are two op amps associated with each output channel of the MAX1464. At any given time, only one of the two op amps can be connected to an output terminal, and the unused op amp can be used as…
Can the second-order compensation algorithm built into the MAX1464 Control Program be used for real compensation in production?

Yes. The coefficients in the template file must be replaced with the coefficients specific to the sensor production module.
Does the input impedance of the MAX1464 change with different PGA gain settings? How?

Yes. The input impedance as a function of PGA setting can be calculated by the expressions below, where "f" is the ADC clock frequency, and "Gain" is the PGA gain. A partial list of input impedance vs…
