TLV2780ID Equivalent & Substitute Parts

Part Overview

The TLV2780ID is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This device features rail-to-rail output capability and is designed for low-voltage applications with a supply voltage range of 1.8 V to 3.6 V. The TLV2780ID is classified as obsolete, necessitating identification of active substitute components that maintain functional and electrical compatibility for ongoing production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute components for the TLV2780ID are selected based on the following critical parameters that determine functional and electrical compatibility:

Package Compatibility: All substitute parts maintain the 8-SOIC (0.154", 3.90mm Width) surface mount package, ensuring direct mechanical and electrical pin compatibility without PCB redesign.

Amplifier Classification: All substitutes are general-purpose operational amplifiers with single-circuit configuration and rail-to-rail output capability, matching the core functional requirements of the original device.

Electrical Characteristics: Substitute parts are evaluated on voltage supply span, input bias current, input offset voltage, slew rate, and gain bandwidth product. The TLV2780ID operates within 1.8 V to 3.6 V; substitute parts must support this range or provide extended compatibility.

Compliance and Certification: All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and REACH unaffected status, ensuring regulatory alignment with the original component.

Product Status: Active substitute parts are prioritized to ensure long-term availability and continued manufacturing support, addressing the obsolescence of the original TLV2780ID.

Engineering Selection Recommendations

MAX4166ESA+ and MAX4166ESA+T: These Analog Devices Inc./Maxim Integrated components provide direct functional substitution with identical input offset voltage (250 µV) and matching package geometry. Both variants are active products with full ROHS3 compliance and MSL Level 1 certification. The MAX4166ESA+T variant offers higher output current capability (125 mA) compared to the standard MAX4166ESA+ and is supplied in Tape & Reel packaging for high-volume production environments. The minimum supply voltage of 2.7 V exceeds the TLV2780ID's 1.8 V minimum, requiring verification that application circuits operate above this threshold.

MAX4323ESA+ and MAX4323ESA+T: These Analog Devices Inc./Maxim Integrated components provide functional substitution with extended minimum supply voltage support (2.4 V), closer to the original TLV2780ID specification. Input offset voltage is higher at 700 µV compared to the original 250 µV specification. Both variants maintain active product status with full regulatory compliance. The MAX4323ESA+T variant is supplied in Tape & Reel packaging and provides 50 mA output current capability. Supply current consumption (725 µA) is lower than the MAX4166 series, offering improved power efficiency in battery-powered applications.

All substitute parts maintain surface mount 8-SOIC package compatibility, eliminating PCB redesign requirements. Selection between MAX4166 and MAX4323 series depends on application-specific requirements for input offset voltage tolerance and minimum supply voltage operation.

Frequently Asked Questions (FAQ)

Q: Can the MAX4166ESA+ directly replace the TLV2780ID without PCB modifications?

A: Yes. Both components use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout, enabling direct substitution without PCB redesign. However, the minimum supply voltage requirement of 2.7 V for the MAX4166ESA+ must be verified against application circuit design.

Q: What is the primary difference between MAX4166ESA+ and MAX4166ESA+T?

A: Both parts are electrically identical with matching electrical specifications. The primary difference is packaging: MAX4166ESA+ is supplied in Tube packaging, while MAX4166ESA+T is supplied in Tape & Reel (TR) format. The MAX4166ESA+T also specifies higher output current capability (125 mA) compared to the standard variant. Tape & Reel packaging is standard for automated assembly processes in high-volume production.

Q: How do the MAX4323 variants differ from the MAX4166 series?

A: The MAX4323 series provides lower minimum supply voltage operation (2.4 V versus 2.7 V), closer to the original TLV2780ID specification of 1.8 V. However, MAX4323 components specify higher input offset voltage (700 µV versus 250 µV). Supply current consumption is lower in the MAX4323 series (725 µA versus 1.3 mA), providing power efficiency advantages. Selection depends on whether input offset voltage tolerance or minimum supply voltage operation is the critical design parameter.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed (MAX4166ESA+, MAX4166ESA+T, MAX4323ESA+, MAX4323ESA+T) maintain ROHS3 compliance and MSL Level 1 certification, matching the regulatory status of the original TLV2780ID.

Q: What is the impact of the TLV2780ID's higher slew rate (5 V/µs) compared to substitute parts (2 V/µs)?

A: The TLV2780ID specifies 5 V/µs slew rate, while all substitute parts specify 2 V/µs. Slew rate determines the maximum rate of voltage change at the output. Applications requiring high-speed signal transitions may be affected by the lower slew rate of substitute components. Circuit performance must be evaluated for applications with fast transient requirements.

Q: Can the MAX4166ESA+ operate at the TLV2780ID's minimum supply voltage of 1.8 V?

A: No. The MAX4166ESA+ specifies a minimum supply voltage of 2.7 V and cannot operate at 1.8 V. For applications requiring operation below 2.7 V, the MAX4323ESA+ or MAX4323ESA+T (minimum 2.4 V) provides closer compatibility, though still above the original 1.8 V specification.

Q: What is the operating temperature range difference between the TLV2780ID and substitute parts?

A: The TLV2780ID operates across -40°C to 125°C, while all substitute parts operate across -40°C to 85°C. Applications requiring operation above 85°C cannot use these substitute components.

Q: Is the higher input bias current of substitute parts (50 nA versus 2.5 pA) significant?

A: The TLV2780ID specifies extremely low input bias current of 2.5 pA, while substitute parts specify 50 nA. This represents a significant difference relevant to high-impedance input circuits. Applications with very high source impedances may experience different input bias current effects with substitute components.
