Ultraprecise Instrumentation Amplifier Makes
Robust Thermocouple Interface вЂ“ Design Note 302
Jon Munson
Introduction
The versatile and precise LTC В®2053 instrumentation
ampliп¬Ѓer provides an excellent platform for robust, low
power instrumentation productsвЂ”as exempliп¬Ѓed below
by the battery-powered thermocouple ampliп¬Ѓer circuit.
The LTC2053 offers exceptionally low 10ОјV maximum
input offset along with 116dB typical CMRR and PSRR,
a result of a combination of switched capacitor and zerodrift op amp technologies. It is optimized for low voltage
supplies from 2.7V to 11V single ended or up to В±5.5V with
split supplies. The LTC2053 is ideal for battery-powered
instrument applications because of its low 850ОјA typical
current draw. The gain is easily programmed with two
resistors, as shown in Figure 1, just like a traditional
non-inverting op amp. The LTC2053 also features low
1/f noise and rail-to-rail I/O to maximize dynamic range.
The Requirements of Thermocouple Ampliп¬Ѓcation
A robust thermocouple ampliп¬Ѓcation circuit must meet
several speciп¬Ѓc requirements. First, a commonly used
type K thermocouple develops 40.6ОјV/В°C, and a standard
readout scale is 10mV/В°C, so a precision ampliп¬Ѓer with …
