Substitute Part Grouping Explanation

Substitute parts for the THS4012CDGNG4 are identified based on strict electrical and mechanical parameter matching within the voltage feedback operational amplifier category. The substitution logic is structured as follows:

Primary Substitute (MFR Recommended): THS4012CDGN maintains identical electrical specifications and functional performance. The distinction between THS4012CDGNG4 and THS4012CDGN is packaging format only (Tube versus standard packaging). Both devices share the same base product number THS4012, identical circuit count (2 circuits), and all critical performance parameters including slew rate, bandwidth, and supply specifications.

Parametric Equivalent: THS4011CDGN is classified as a parametric equivalent due to a single functional difference: it contains 1 circuit instead of 2 circuits. All other electrical parameters—slew rate (310 V/µs), gain bandwidth product (290 MHz), input bias current (2 µA), input offset voltage (1 mV), supply current (7.8 mA), output current per channel (110 mA), and supply voltage range (9 V to 32 V)—are identical. The THS4011CDGN operates within the same temperature range and package configuration.

Key Parameters Determining Substitution:

• Amplifier Type: Voltage Feedback
• Slew Rate: 310 V/µs
• Gain Bandwidth Product: 290 MHz
• Input Bias Current: 2 µA
• Input Offset Voltage: 1 mV
• Supply Voltage Range: 9 V to 32 V
• Package / Case: 8-TSSOP, 8-MSOP with Exposed Pad
• Mounting Type: Surface Mount

Both substitute parts maintain full compliance with regulatory requirements including ROHS3 and REACH standards.

Frequently Asked Questions (FAQ)

Q: Can THS4012CDGN be used as a direct replacement for THS4012CDGNG4 without circuit modifications?

A: Yes. The THS4012CDGN is electrically and functionally identical to the THS4012CDGNG4. Both devices contain 2 voltage feedback amplifier circuits with identical specifications for slew rate, bandwidth, input characteristics, and supply requirements. The only difference is packaging format. No circuit modifications are required.

Q: What is the difference between THS4012CDGNG4 and THS4012CDGN?

A: The primary difference is packaging. THS4012CDGNG4 uses standard packaging while THS4012CDGN is supplied in Tube packaging. All electrical specifications, performance parameters, and functional characteristics are identical. Both use the 8-HVSSOP package with identical pin configuration and exposed pad design.

Q: When should THS4011CDGN be selected instead of THS4012CDGN?

A: THS4011CDGN should be selected when the application requires only a single amplifier circuit. The THS4011CDGN contains 1 circuit versus 2 circuits in the THS4012CDGN. All other electrical parameters are identical. If your design uses only one of the two amplifier circuits in the THS4012CDGNG4, the THS4011CDGN provides equivalent performance with a single-circuit configuration.

Q: Are all three parts compatible with the same PCB layout and footprint?

A: Yes. All three parts—THS4012CDGNG4, THS4012CDGN, and THS4011CDGN—use the identical 8-TSSOP, 8-MSOP package with 0.118" width (3.00mm) and exposed pad. The pin configuration and footprint are identical, allowing direct substitution on the same PCB without layout modifications.

Q: Do these parts meet current regulatory compliance requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected. Both substitute parts (THS4012CDGN and THS4011CDGN) maintain active product status with Texas Instruments, ensuring ongoing availability and compliance with current environmental and regulatory standards.

Q: What is the supply voltage compatibility across all three parts?

A: All three parts operate with identical supply voltage specifications: minimum 9 V and maximum 32 V. This wide supply range ensures compatibility across diverse application requirements without design modifications.

Q: Are there any differences in thermal or moisture sensitivity characteristics?

A: No. All three parts share identical operating temperature range (0°C to 70°C) and Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Thermal and moisture handling requirements are identical across all substitute options.
