OPA726AIDGKTG4

Instrumentation, Op Amps, Buffer Amps Overview

The OPA726AIDGKTG4 is a single-channel, high-speed CMOS operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 20 MHz and a slew rate of 30 V/us. The device operates on a supply voltage range of 4 V to 12 V (±2 V to ±6 V) with a typical quiescent current of 4.3 mA per channel. Key electrical specifications include an input offset voltage of 3 mV, input bias current of 200 pA, and an input voltage noise density of 10 nV/√Hz. It provides a common-mode rejection ratio of 94 dB and can deliver up to 40 mA output current per channel. The component is housed in an 8-pin VSSOP package and supports operation from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as defined by Texas Instruments. Confirm the package type is VSSOP-8 and check for moisture sensitivity levels prior to soldering. Ensure the operating temperature range meets the application requirements of -40°C to +125°C. Cross-reference the datasheet revision to ensure compatibility with design specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a balance of speed, low noise, and rail-to-rail I/O is required in a single-channel configuration. It is suitable for applications where power consumption must be minimized without sacrificing bandwidth. Consider the 40 mA output drive capability for direct interfacing with ADCs or transmission lines. Evaluate the 3 mV offset voltage against system accuracy requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the OPA72x series of high-speed, low-power CMOS operational amplifiers from Texas Instruments. The series is designed for applications demanding both speed and efficiency. The OPA726 is the single-channel variant, while other members may offer dual or quad configurations. The G4 suffix typically denotes environmental compliance within the manufacturer's portfolio.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for OPA726 variants with different suffixes such as IDGKR or IDGK for tape-and-reel or tube packaging options. Verify if the non-G4 version meets environmental requirements. Compare pinouts and electrical parameters with other single-channel op-amps in the same package if alternative sourcing is needed.
