Low-Voltage Analog Temperature
Sensor in an SC70 Package
MAX613
General Description
Features
The MAX6613 is a low-power precision analog output
temperature sensor in a tiny 5-pin SC70 package. The
MAX6613 operates over a 1.8V to 5.5V supply voltage
range, with a typical current consumption of only 7.5µA.
It is particularly well suited for portable applications
where minimizing battery cost and maximizing useful
battery life are crucial.
♦ 1.8V to 5.5V Supply Voltage
♦ 4.0°C Accuracy
♦ Low Supply Consumption, 7.5µA (typ)
♦ -55°C to +130°C Temperature Range
♦ SC70 Package
The MAX6613 provides an analog voltage output pro-
portional to temperature. Accuracy is ±±.0ꢀC ꢁmaxꢂ
♦ Pin Compatible to LM20
over a range of T = 0ꢀC to +50ꢀC and ±±.±ꢀC ꢁmaxꢂ
A
from T = -20ꢀC to +80ꢀC. Self-heating effects are neg-
A
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 -55ꢀC to
+130ꢀC range with a 2.5V to 5.5V supply voltage. For
applications with a supply voltage of 1.8V, the
MAX6613 can be used over a +25ꢀC to +130ꢀC tem-
perature range.
