Frequently Asked Questions
What is the input offset voltage drift of the OPA2735AID?
The OPA2735AID features a maximum offset voltage drift of 0.05µV/°C, achieved through its chopper-stabilized (zero-drift) architecture. This makes it suitable for precision applications where temperature-induced offset errors must be minimized over the full operating range.
What are the typical applications for the OPA2735AID?
The OPA2735AID is commonly used in precision instrumentation, thermocouple signal conditioning, strain gauge and bridge amplifiers, medical diagnostic equipment, industrial 4-20mA transmitters, and data acquisition systems. Its ultra-low drift and high CMRR of 130dB (typical) make it well-suited for any application requiring accurate DC amplification.
What package and supply voltage does the OPA2735AID support?
The OPA2735AID is housed in a Small Outline (SOIC-8) package. It operates from a single supply and is designed for low-voltage CMOS systems. The dual-channel design provides two independent op-amp channels in one compact package, reducing board space and simplifying layout.
What is the input bias current of the OPA2735AID?
The OPA2735AID has a maximum input bias current (IIB) of 0.2nA (0.0002µA) at 25°C, with a maximum input offset current (IIO) of 0.3nA. These extremely low values make it ideal for interfacing with high-impedance sensors such as pH electrodes and photodiodes without introducing significant measurement errors.
