Key Features

  • Zero-drift chopper-stabilized architecture delivers 0.05µV/°C (max) offset voltage drift for exceptional long-term precision
  • Ultra-low input bias current of 0.2nA (max) minimizes error in high-impedance sensor applications
  • 115dB minimum CMRR (130dB typical) ensures excellent noise rejection in differential signal paths
  • Single-supply CMOS design with rail-to-rail capability suits low-voltage 3.3V/5V systems
  • Dual-channel configuration in Small Outline Package reduces board space and BOM cost

Applications

OPA2735AID is ideal for precision instrumentation amplifiers, thermocouple and bridge sensor signal conditioning, and medical diagnostic equipment where ultra-low offset drift is critical. Its chopper-stabilized architecture suits data acquisition front-ends, industrial 4-20mA transmitters, and weigh-scale circuits requiring DC accuracy over wide temperature ranges. The dual-channel configuration also fits active filter designs and audio measurement systems demanding low noise and high CMRR.

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.
