The MAX6610/MAX6611 are precise, low-power analog temperature sensors combined with a precision voltage reference. They are ideal for applications involving analog-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. The MAX6610 operates from 3.0V to 5.5V and has a 2.560V reference output. The MAX6611 operates from a 4.5V to 5.5V power supply and has a 4.096V 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.
The MAX6610 and MAX6611 are precise, low‑power analog temperature sensors that include a precision voltage reference. They are supplied in a 6‑pin SOT‑23 package and operate over a temperature range of –40 °C to +125 °C, making them suitable for system temperature monitoring, temperature compensation, HVAC, and home‑appliance applications.
Key features include ±1 °C accuracy, a reference output of 2.560 V (MAX6610) or 4.096 V (MAX6611), low supply current (typical 150 µA, 1 µA in shutdown), and the ability to drive loads up to 1 mA on the REF pin and 0.2 µF on the TEMP pin. The devices provide linear temperature‑to‑voltage conversion (10 mV/°C for MAX6610, 16 mV/°C for MAX6611) and include a shutdown pin for power‑saving operation.
