Frequently Asked Questions
What is the input offset voltage of the OPA197IDBVR?
The OPA197IDBVR has a maximum input offset voltage of 100µV, with typical performance well below that. This precision specification makes it suitable for applications that require accurate DC signal amplification, such as strain gauge bridges, thermocouple amplifiers, and precision instrumentation circuits.
What supply voltage range does the OPA197IDBVR support?
The OPA197IDBVR operates over a wide supply voltage range of up to 36V (or ±18V dual supply). It features true rail-to-rail input and output (RRIO), allowing the input common-mode voltage and output swing to extend to both supply rails, maximizing usable dynamic range in single-supply designs.
What are typical applications for the OPA197IDBVR?
The OPA197IDBVR is commonly used in precision sensor interfaces, data acquisition systems, medical instrumentation, battery-powered handheld devices, industrial process control, and active filter designs. Its low bias current of 20pA at 25°C makes it especially well-suited for high-impedance photodiode and pH sensor amplification circuits.
What package does the OPA197IDBVR come in, and are alternatives available?
The OPA197IDBVR is housed in a compact SOT-23 5-pin (DBV) package, ideal for space-constrained PCB layouts. Texas Instruments also offers the OPA197 in other packages such as the SC70 (DCK) for even smaller footprints and the SOIC-8 (D) package for easier hand-soldering during prototyping.
