Datasheet
The MAX6610/MAX6611 are precise, low-power analog
temperature sensors combined with a precision voltage
reference. They are ideal for applications involving ana-
log-to-digital converters (ADCs), where the MAX6610/
MAX6611 provide the reference voltage for the ADC
and develop a temperature output voltage that is
scaled to provide convenient ADC output codes. An 8-
bit ADC’s LSB is equal to 1°C, while a 10-bit ADC’s LSB
corresponds to 0.25°C.
The MAX6610/MAX6611 are available in two versions.
The MAX6611 operates from a 4.5V to 5.5V power sup-
ply and has a 4.096V reference output. The MAX6610
operates from 3.0V to 5.5V and has a 2.560V reference
output. Power-supply current is less than 150µA (typ).
Both the MAX6610/MAX6611 are available in a 6-pin
SOT23 package and operate from -40°C to +125°C.
