Parameter Comparison

Engineering Selection Recommendations

The THS4151CDGK is a direct parametric equivalent to the THS4150CDGK. Both devices are manufactured by Texas Instruments and share identical electrical specifications, mechanical package dimensions, and compliance certifications.

The primary distinction between these parts is product status: the THS4150CDGK is classified as obsolete, while the THS4151CDGK maintains active product status. For new designs and ongoing production requiring a differential amplifier with 340 MHz gain bandwidth product and 650 V/µs slew rate in an 8-VSSOP package, the THS4151CDGK is the appropriate selection.

Both parts satisfy ROHS3 compliance requirements, maintain MSL Level 1 (unlimited moisture sensitivity), and are REACH unaffected. The electrical performance, supply voltage range (4 V to 33 V), input bias current (4.3 µA), and output current capability (85 mA per channel) are identical across both devices.

Frequently Asked Questions (FAQ)

Q: Can the THS4151CDGK directly replace the THS4150CDGK in existing designs?

A: Yes. The THS4151CDGK is a parametric equivalent with identical electrical specifications, package dimensions, and pin configuration. No circuit modifications are required for direct substitution.

Q: What is the difference between the THS4150CDGK and THS4151CDGK?

A: The devices are electrically and mechanically identical. The primary difference is product lifecycle status: THS4150CDGK is obsolete, while THS4151CDGK is active. The THS4151CDGK is the recommended part for current and future applications.

Q: Are the package dimensions identical between these parts?

A: Yes. Both the THS4150CDGK and THS4151CDGK use the 8-VSSOP package with dimensions of 8-TSSOP, 8-MSOP (0.118", 3.00mm Width). PCB layouts and footprints are interchangeable.

Q: Do both parts meet the same compliance standards?

A: Yes. Both devices are ROHS3 compliant, maintain MSL Level 1 (unlimited), and are REACH unaffected. Compliance documentation is equivalent for both parts.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching: amplifier type (differential), number of circuits (1), slew rate (650 V/µs), gain bandwidth product (340 MHz), -3dB bandwidth (150 MHz), input bias current (4.3 µA), input offset voltage (1.1 mV), supply current (17.5 mA), output current per channel (85 mA), and supply voltage range (4 V to 33 V).
