What the OPA2735AIDGKR brings to a precision signal chain
The Texas Instruments OPA2735AIDGKR is a dual zero-drift operational amplifier with 1 µV input offset voltage. Gain-bandwidth product is 1.6 MHz, supply current is 600 µA per channel.
1 µV offset — the zero-drift payoff
A conventional op-amp drifts tens of microvolts over temperature; the OPA2735AIDGKR's auto-zero architecture keeps offset at 1 µV across the -40°C to 85°C industrial range. That stability means the error budget stays tight for bridge sensors, medical instrumentation, or any DC-coupled measurement where a few microvolts of drift would swamp the signal. Input bias current is 100 pA, so high-impedance sources like photodiodes or pH probes do not load the node.
Supply range and output swing
The amplifier runs from 2.7 V to 12 V. Rail-to-rail output allows the signal to swing close to the supply rails.
Package and footprint
The 8-VSSOP (3.00 mm body width) is a compact surface-mount package. The supplier device package is listed as 8-VSSOP.
Lifecycle and sourcing
The OPA2735AIDGKR carries an Active product status with ROHS3 compliance. No last-time-buy or end-of-life notice is on record.
