Frequently Asked Questions
What is the input offset voltage drift of the OPA2735AIDR?
The OPA2735AIDR achieves a maximum offset voltage drift of 0.05 µV/°C, guaranteed over the full operating temperature range. This ultra-low drift is achieved through its chopper-stabilized (zero-drift) architecture, making it suitable for precision measurement applications requiring long-term DC stability.
What is the CMRR of the OPA2735AIDR and why does it matter?
The OPA2735AIDR specifies a minimum CMRR of 115 dB and a typical CMRR of 130 dB. High CMRR is critical in differential measurement applications such as bridge sensors and instrumentation amplifiers, as it ensures that common-mode noise and ground voltage differences do not corrupt the output signal.
What package does the OPA2735AIDR come in and is it RoHS compliant?
The OPA2735AIDR is packaged in an SOIC-8 (Small Outline IC, 8-pin) surface-mount package. It is RoHS compliant (lead-free), as indicated by its Pbfree Code of Yes, making it suitable for use in environmentally regulated products.
What are typical application areas for the OPA2735AIDR?
Typical applications include precision sensor amplification for thermocouples, RTDs, and Wheatstone bridge circuits, as well as analog front ends for 24-bit ADCs in industrial data acquisition systems, medical monitoring devices, and precision voltage references requiring sub-microvolt accuracy over temperature.
