Rainbow Electronics MAX6613 - Manual

General Description
The MAX6613 is a low-power analog precision analog
output temperature sensor in a tiny 5-pin SC70 pack-
age. The MAX6613 operates over a supply voltage
range of 1.8V to 5.5V, with a typical current consump-
tion of only 7.5µA. It is particularly well suited for
portable applications where minimizing battery cost
and maximizing useful battery life are crucial.
The MAX6613 provides an analog voltage output pro-
portional to temperature. Accuracy is ±1.3°C (max)
over a range of T
A = 0°C to +50°C and ±2.0°C (max)
from T A = -20°C to +80°C. Self-heating effects are neg-
ligible due to the low current consumption of the part.
Unlike many analog temperature sensors, the MAX6613
is stable with any capacitive load from 0pF to 1000pF,
providing broad flexibility in board-level design.
The operating temperature range varies with the volt-
age supply. The MAX6613 can be used over a range of
-55°C to +130°C with a supply voltage of 2.5V to 5.5V.
For applications with a supply voltage of 1.8V, the
MAX6613 can be used over a temperature range of
+25°C to +130°C.
