OPA2206ADT

Instrumentation, Op Amps, Buffer Amps Overview

The OPA2206ADT is a dual precision operational amplifier from Texas Instruments, featuring integrated input overvoltage protection up to ±40 V beyond supplies. It utilizes e-trim™ technology for low offset voltage (±25 µV max) and drift (±0.5 µV/°C max). Key electrical parameters include a gain bandwidth product of 3.6 MHz, slew rate of 4 V/µs, and quiescent current of 240 µA per amplifier. The device operates on a supply voltage range of 4.5 V to 36 V and supports temperatures from –40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrated input overvoltage protection safeguards against signals exceeding the supply range by up to 40 V.
• Super-beta inputs provide extremely low input bias current and current noise density.
• e-trim™ trimming technology ensures high precision with minimal offset voltage and drift across temperature.
• Rail-to-rail output capability allows signal swing close to both supply rails.

Instrumentation, Op Amps, Buffer Amps Applications

• Analog input modules
• Mixed module systems (AI, AO, DI, DO)
• Lab and field instrumentation
• Source measurement units (SMU)
• Digital multimeters (DMM)

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package variant, as the OPA2206 family includes SOIC-8 and VSSOP-8 options. Confirm that the ADT suffix corresponds to the desired tape-and-reel packaging configuration. Ensure the design accounts for the thermal characteristics associated with the selected package type under maximum operating conditions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high precision and robust input protection are required in a single package. It serves as an upgrade to the OPA2205, adding overvoltage protection at the cost of slightly higher broadband noise. Ideal for applications where external protection circuitry would otherwise increase board space and complexity.

Instrumentation, Op Amps, Buffer Amps Part Context

The OPA2206ADT belongs to the OPAx206 family, which succeeds the industry-standard OPAx277 series. This generation introduces proprietary input overvoltage protection while maintaining the super-beta bipolar input stage characteristics. The dual-channel configuration provides two independent amplifiers in one package, optimizing space for dense analog front-end designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

OPA2205: Similar performance but lacks input overvoltage protection. OPA206: Single-channel version of the same core. OPA4206: Quad-channel version available in 14-pin packages.
