Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLC2652AC-8D is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Amplifier Type: Zero-Drift architecture
• Number of Circuits: Single circuit configuration
• Package / Case: 8-SOIC form factor with 0.154" (3.90mm) width
• Mounting Type: Surface Mount
• Operating Temperature Range: 0°C to 70°C minimum
• Supply Voltage Range: Minimum 3.8 V to maximum 16 V overlap required

Performance Parameters for Compatibility Assessment:

• Input Offset Voltage: 0.5 µV baseline
• Slew Rate: 3.1 V/µs baseline
• Gain Bandwidth Product: 1.9 MHz baseline
• Input Bias Current: 4 pA baseline
• Supply Current: 1.5 mA baseline
• Output Current per Channel: 50 mA baseline

The ICL7650SCBA-1Z qualifies as a substitute based on matching amplifier type, circuit count, package geometry, mounting method, and operating temperature range. Supply voltage overlap and electrical performance parameters remain within acceptable substitution criteria for zero-drift amplifier applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TLC2652AC-8D and ICL7650SCBA-1Z are active-status components with full ROHS3 compliance and unlimited moisture sensitivity ratings, ensuring compatibility with modern manufacturing and environmental standards. Both devices maintain identical operating temperature ranges (0°C to 70°C) and identical maximum supply voltage limits (16 V).

The TLC2652AC-8D offers superior slew rate performance (3.1 V/µs versus 2.5 V/µs) and higher output current capability (50 mA versus 30 mA per channel). The TLC2652AC-8D also supports lower minimum supply voltage operation (3.8 V versus 4.5 V).

The ICL7650SCBA-1Z provides marginally higher gain bandwidth product (2.0 MHz versus 1.9 MHz) and identical input bias current specification (4 pA). Input offset voltage differs by 0.2 µV (0.7 µV versus 0.5 µV), representing a 40% increase in offset specification.

Selection between these components depends on application requirements for slew rate, output current, minimum supply voltage, and input offset voltage tolerance. Both devices are certified for equivalent regulatory and compliance status.

Frequently Asked Questions (FAQ)

Q: Can the ICL7650SCBA-1Z directly replace the TLC2652AC-8D in existing PCB designs?

A: Direct physical replacement is possible due to identical 8-SOIC package geometry and pin configuration. However, electrical performance differences require circuit validation. The ICL7650SCBA-1Z operates at a minimum supply voltage of 4.5 V (versus 3.8 V for the TLC2652AC-8D), limiting compatibility in low-voltage applications. Output current capability is reduced from 50 mA to 30 mA per channel.

Q: What are the key electrical differences between these two zero-drift amplifiers?

A: The TLC2652AC-8D provides faster slew rate (3.1 V/µs), higher output current (50 mA), lower minimum supply voltage (3.8 V), and lower input offset voltage (0.5 µV). The ICL7650SCBA-1Z offers slightly higher gain bandwidth product (2.0 MHz) and identical input bias current (4 pA). Supply current consumption differs by 0.5 mA (1.5 mA versus 2.0 mA).

Q: Are both devices suitable for precision instrumentation applications?

A: Both devices are zero-drift amplifiers with input offset voltages below 1 µV, qualifying them for precision measurement applications. The TLC2652AC-8D's lower offset voltage (0.5 µV) provides superior accuracy margin. Application-specific requirements for slew rate, output current, and supply voltage range determine optimal component selection.

Q: What compliance certifications apply to both components?

A: Both the TLC2652AC-8D and ICL7650SCBA-1Z are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (unlimited). Both carry EAR99 export classification and HTSUS code 8542.33.0001.

Q: Does package form factor differ between these substitutes?

A: No. Both components use identical 8-SOIC surface-mount packaging with 0.154" (3.90mm) width specification. PCB footprint and reflow soldering parameters remain unchanged between devices.
