Key Parameters

Substitute Part Grouping Explanation

Substitution of the CLC4000ISO14X is determined by the following critical parameters that define functional equivalence:

Primary Substitution Criteria:

• Amplifier Type: Voltage Feedback (required match)
• Number of Circuits: 4 (required match)
• Package / Case: 14-SOIC form factor (required match for PCB compatibility)
• Operating Temperature Range: -40°C ~ 85°C (required match)
• Mounting Type: Surface Mount (required match)

Secondary Compatibility Parameters:

• Slew Rate: Minimum 210 V/µs
• -3dB Bandwidth: Minimum 250 MHz
• Current - Input Bias: Maximum 10 µA
• Voltage - Input Offset: Maximum 300 µV
• Voltage - Supply Span: Minimum 5 V to Maximum 12 V overlap required

The substitute parts identified (LT1817IS#PBF and OPA4820ID) satisfy the primary criteria and meet or exceed the secondary performance parameters, enabling direct functional replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

LT1817IS#PBF (Analog Devices Inc.): This substitute part carries Last Time Buy status, indicating limited future availability. It demonstrates superior performance across multiple parameters: slew rate of 1500 V/µs (7.1× higher), -3dB bandwidth of 350 MHz (40% higher), and input bias current of 2 µA (80% lower). The device is ROHS3 compliant with MSL 1 rating (unlimited moisture exposure tolerance). Supply voltage range of 2.5 V to 11 V provides broader operational flexibility. However, output current per channel is limited to 80 mA compared to the original 1 A specification.

OPA4820ID (Texas Instruments): This substitute part maintains Active product status, ensuring long-term availability and continued manufacturer support. It provides the highest -3dB bandwidth at 650 MHz and slew rate of 240 V/µs. The device is ROHS3 compliant with supply voltage range of 4 V to 12.6 V. Output current per channel is 85 mA. Total supply current consumption is elevated at 22.6 mA compared to 6.75 mA of the original part. The OPA4820ID includes differential output configuration, distinguishing it from the original single-ended topology.

Selection Basis:

• For applications requiring extended product lifecycle and manufacturer support: OPA4820ID
• For applications prioritizing low input bias current and high slew rate performance: LT1817IS#PBF
• Both devices satisfy primary substitution criteria and operate within the -40°C to 85°C temperature range
• Both devices are ROHS3 compliant, supporting environmental and regulatory requirements

Frequently Asked Questions (FAQ)

Q: Can the LT1817IS#PBF and OPA4820ID be used interchangeably with the CLC4000ISO14X?

A: Both devices satisfy the primary substitution criteria: 4-circuit voltage feedback amplifier topology, 14-SOIC package form factor, and -40°C to 85°C operating temperature range. However, differences in output current capability, supply current consumption, and output configuration (differential vs. single-ended) require circuit-level evaluation. The OPA4820ID features differential outputs, which may require circuit topology modifications if single-ended outputs are required.

Q: What is the impact of the higher slew rate in the LT1817IS#PBF?

A: The LT1817IS#PBF slew rate of 1500 V/µs is 7.1 times higher than the original CLC4000ISO14X specification of 210 V/µs. This parameter determines the maximum rate of voltage change at the output. Higher slew rate reduces distortion in high-frequency signal applications and improves transient response. This enhancement is beneficial for most applications and does not introduce compatibility issues.

Q: Why does the OPA4820ID consume more supply current?

A: The OPA4820ID total supply current is 22.6 mA compared to 6.75 mA for the CLC4000ISO14X. This increased consumption reflects the higher bandwidth capability (650 MHz vs. 250 MHz) and differential output architecture. Power supply design and thermal management must account for this increased current draw in system-level implementations.

Q: Are there output current limitations with the substitute parts?

A: The original CLC4000ISO14X specifies 1 A output current per channel. The LT1817IS#PBF and OPA4820ID are limited to 80 mA and 85 mA per channel respectively. Applications requiring output currents exceeding 80 mA must incorporate external buffering or output stage amplification.

Q: What is the significance of the Last Time Buy status for LT1817IS#PBF?

A: Last Time Buy status indicates that Analog Devices has announced end-of-life for this product. Existing inventory is available for purchase, but production will cease. For long-term production requirements, the OPA4820ID with Active status is the preferred selection to ensure sustained availability.

Q: How do the input offset voltage specifications compare?

A: The CLC4000ISO14X specifies 300 µV input offset voltage. The LT1817IS#PBF and OPA4820ID specify 200 µV and 250 µV respectively. Lower input offset voltage reduces DC errors in precision analog circuits. Both substitute parts provide improved performance in this parameter.

Q: What packaging considerations apply to these substitutes?

A: All three devices utilize the 14-SOIC (0.154", 3.90mm Width) surface mount package, ensuring PCB footprint compatibility. The CLC4000ISO14X and OPA4820ID share identical MSL 2 (1 Year) moisture sensitivity ratings. The LT1817IS#PBF features superior MSL 1 (Unlimited) rating, reducing moisture-related handling and storage constraints.
