MCP9600/L00
Thermocouple EMF to Temperature Converter,
1.5C Maximum Accuracy
Features Description
Thermocouple Electromotive Force (EMF) to C Microchip Technology Inc.s MCP9600/L00 converts
Converter: thermocouple EMF to degree Celsius with integrated
cold-junction compensation. This MCP9600 corrects
- Integrated Cold-Junction Compensation
the thermocouple nonlinear error characteristics of
Supported Types (designated by NIST ITS-90):
eight thermocouple types and outputs 0.5C/1.5C
- Type K, J, T, N, S, E, B and R
(Typ./Max.) accurate temperature data for the selected
Sensor Accuracy for Thermocouple Hot-Junction
thermocouple Hot-Junction temperature. And the
- MCP9600 0.5C/1.5C (Typ./Max.)
MCP96L00 outputs 2.0C/4.0C (Typ./Max.)
accurate temperature data. The correction coefficients
- MCP96L00 2.0C/4.0C (Typ./Max.)
are derived from the National Institute of Standards and
Measurement Resolution:
Technology (NIST) ITS-90 Thermocouple Database.
- Hot and Cold-Junctions: +0.0625C (typical)
The MCP9600/L00 digital temperature sensor comes
Four Programmable Temperature Alert Outputs:
with user-programmable registers which provide
- Monitor Hot or Cold-Junction Temperatures
design flexibility for various temperature sensing
- Detect Rising or Falling Temperatures
applications. The registers allow user-selectable
- Up to 255C of Programmable Hysteresis
settings, such as Low-Power modes for
Programmable Digital Filter for Temperature battery-powered applications, adjustable digital filter for
fast transient temperatures and four individually
Low Power:
programmable temperature alert outputs which can be
- Shutdown Mode
used to detect multiple temperature zones.
- Burst Mode: 1 to 128 Temperature Samples
2 The temperature alert limits have multiple
2-Wire Interface: I C Compatible, 100 kHz:

Operating Voltage Range: 2.7V to 5.5V
output, and output function as a Comparator mode
Operating Current: 300 A (typical)
(useful for thermostat-type operation) or Interrupt mode
for microprocessor-based systems. In addition, the
Shutdown Current: 2 A (typical)
alerts can detect either a rising or a falling temperature
Package: 20-lead MQFN
with up to +255C hysteresis.
