TC1046, TC1047/A and MCP9700/1
Voltage Output Temperature Sensor Family
Product Summary:
The TC1046, TC1047/A and MCP9700/1 are voltage
output temperature sensing products in space-saving
packages.
The TC1046, TC1047/A and MCP9701 develop an
output voltage proportional to temperature with a
nominal temperature coefficient of 6.25 mV/°C,
10 mV/°C and 19.53 mV/°C respectively. The MCP9700
and TC1047/A provide a linear temperature slope of
10 mV/C. All these products can sense a -40°C to
+125°C temperature range while operating from a single
supply. The devices feature an offset voltage that allows
reading negative temperatures without the need for a
negative supply voltage. The extremely low-operating
current minimizes self-heating and maximizes battery life.
The TC1046 and TC1047/A are fully specified from 2.7V
to 4.4V and 2.5V to 5.5V respectively. These devices are
available in small, space-saving 3-lead SOT-23 packages.
The MCP9700 and MCP9701 are fully specified from
2.3V to 5.5V and 3.1V to 5.5V respectively. Both of
these devices are available in ultra-small 5-lead SC-70
packages (∼40% smaller than 5-pin SOT-23).
These devices are suitable for a wide variety of
applications such as the following:
