DATASHEET
High-Temperature, Triple Operational Amplifier
and Voltage Reference
General Description
The CHT-RUBY is a general-purpose tri-
ple operational amplifier combined with a
bandgap voltage reference for applications
with an operating temperature range of -55
to 225°C.
The three operational amplifiers can be
configured in an instrumentation amplifier
with external resistors, while the built-in
voltage reference provides complete
bridge excitation for sensor applications.
The total precision (absolute plus tempera-
ture drift) of the voltage reference is better
than 2%. It exhibits a quiescent current
consumption of 700µA, and an output cur-
rent capability of up to 25mA into an ex-
ternal load at 225°C.
The operational amplifiers can operate
with either single or symmetrical power
supplies. The supply voltages range goes
from 6 to 20V. This circuit is designed and
fabricated with specific CISSOID tech-
niques that enable best-in-class reliability
and lifetime operation.
