General DescriptionThe MAX6695/MAX6696 are precise, dual-remote, andlocal digital temperature sensors. They accurately mea-sure the temperature of the

MAX6695/MAX6696extended temperature register (11h) (Table 3), whichextends the temperature data to 10 bits + sign and theresolution to +0.125°C per LS

MAX6695/MAX6696Reset (MAX6696 Only)The MAX6696’s registers are reset to their power-onvalues if RESET is driven high. When reset occurs, allregisters

byte’s POR state is 06h (4Hz). The MAX6695/MAX6696use only the 3 LSBs of the control register. The 5 MSBsare don’t care and should be set to zero. The

Leakage currents from PC board contaminationmust be dealt with carefully since a 20MΩ leakagepath from DXP to ground causes about +1°C error.If high-v
