Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LT6236CS6#TRPBF is determined by the following critical parameters:

Package Compatibility: The substitute part must use the TSOT-23-6 surface-mount package to ensure mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Functional Classification: The substitute must be classified as a general-purpose operational amplifier with a single circuit and rail-to-rail output capability.

Supply Voltage Range: The substitute's minimum supply voltage must not exceed 3 V, and the maximum supply voltage must accommodate the 12.6 V upper limit of the original part.

Supply Current: The substitute must operate within the 3.3 mA supply current specification to maintain power budget compatibility.

Regulatory Compliance: The substitute must maintain ROHS3 compliance and MSL Level 1 rating to satisfy environmental and manufacturing requirements.

The LMH6611MKE/NOPB from Texas Instruments meets all substitution criteria within these parameters.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (LT6236CS6#TRPBF): Select this Analog Devices component when the application requires the specified 0°C to 70°C operating temperature range and the 215 MHz gain bandwidth product is sufficient for the signal processing requirements. This part maintains active production status with substantial inventory availability (8700 units).

Substitute Part (LMH6611MKE/NOPB): The Texas Instruments LMH6611MKE/NOPB is electrically and mechanically compatible for applications requiring extended operating temperature range (-40°C to 125°C). This substitute provides superior slew rate performance (460 V/µs versus 70 V/µs) and lower input offset voltage (74 µV versus 100 µV), with trade-offs in gain bandwidth product (135 MHz versus 215 MHz) and -3dB bandwidth (365 MHz versus 90 MHz). Both parts maintain identical supply current specifications (3.3 mA) and ROHS3 compliance with MSL Level 1 ratings.

The maximum supply voltage specification of the LMH6611MKE/NOPB (11 V) is within the operating range of the LT6236CS6#TRPBF (12.6 V maximum), and the minimum supply voltage of the LMH6611MKE/NOPB (2.7 V) is below the LT6236CS6#TRPBF minimum (3 V), providing broader supply flexibility.

Frequently Asked Questions (FAQ)

Q: Can the LMH6611MKE/NOPB directly replace the LT6236CS6#TRPBF in existing designs?

A: Direct replacement is possible from a package and pinout perspective, as both devices use the TSOT-23-6 surface-mount package. However, circuit performance differences must be evaluated. The LMH6611MKE/NOPB exhibits higher slew rate (460 V/µs) and lower input offset voltage (74 µV), but lower gain bandwidth product (135 MHz) and -3dB bandwidth (365 MHz). Applications sensitive to bandwidth or slew rate specifications require design verification.

Q: What are the supply voltage compatibility constraints?

A: The LT6236CS6#TRPBF operates from 3 V to 12.6 V. The LMH6611MKE/NOPB operates from 2.7 V to 11 V. The substitute part cannot be used in applications requiring supply voltages above 11 V. Both parts are compatible with supply voltages between 3 V and 11 V.

Q: Are there differences in thermal operating ranges?

A: Yes. The LT6236CS6#TRPBF is specified for 0°C to 70°C operation, while the LMH6611MKE/NOPB is specified for -40°C to 125°C. The substitute part is suitable for extended temperature applications, but the primary part is not rated for operation below 0°C or above 70°C.

Q: Do both parts meet the same regulatory compliance standards?

A: Both the LT6236CS6#TRPBF and LMH6611MKE/NOPB are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity ratings. Both are REACH unaffected and classified under ECCN EAR99 and HTSUS 8542.33.0001.

Q: What is the difference in input bias current between these parts?

A: The LT6236CS6#TRPBF specifies 5 µA input bias current, while the LMH6611MKE/NOPB specifies 6.5 µA. This 1.5 µA difference is negligible for most general-purpose amplifier applications but may be significant in high-impedance signal conditioning circuits.

Q: How do the packaging options differ?

A: The LT6236CS6#TRPBF is supplied in Tape & Reel (TR) packaging, while the LMH6611MKE/NOPB is supplied in Cut Tape (CT) and Digi-Reel® packaging. Both use the identical TSOT-23-6 component package format.
