The Leader in High Temperature Semiconductor Solutions
CHT-RUBY
Version: 2.5
DATASHEET
High-Temperature, Triple Operational Amplifier
and Voltage Reference
General Description
The CHT-RUBY is a general-purpose triple 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 temperature drift) of the voltage reference is better than 2%. It exhibits a quiescent current consumption of 700µA, and an output current capability of up to 25mA into an external load at 225°C.
