OPA2277MDTEP Equivalent & Substitute Parts

Part Overview

The OPA2277MDTEP is a general-purpose operational amplifier IC featuring two circuits in an 8-SOIC surface mount package, manufactured by Texas Instruments. This device is classified as Active product status and is ROHS3 compliant. The OPA2277MDTEP is designed for applications requiring low-power, general-purpose amplification with a 1 MHz gain bandwidth product and operates across a wide supply voltage range of 4V to 36V. Substitute parts are necessary when the original component is unavailable, when alternative packaging formats are required, or when design specifications allow for components with enhanced performance characteristics within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OPA2277MDTEP is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Gain Bandwidth Product: 1 MHz (primary electrical specification)

Secondary Compatibility Parameters:

• Voltage - Supply Span (Min): 4V or lower
• Voltage - Supply Span (Max): 36V or higher
• Operating Temperature Range: Must encompass or match -55°C to 125°C
• Current - Output / Channel: 35 mA or greater
• RoHS Status: ROHS3 Compliant

The substitute parts listed below meet these criteria within the allowed electrical and mechanical parameter ranges for general-purpose dual operational amplifier ICs in 8-SOIC packaging.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are Active product status and ROHS3 compliant, meeting regulatory and environmental requirements equivalent to the OPA2277MDTEP.

ISL28207FBZ-T13 and ISL28207FBZ-T7 (Renesas Electronics): These parts maintain the 1 MHz gain bandwidth product specification and 8-SOIC package format. Both offer improved input bias current (15 pA versus 500 pA) and lower input offset voltage (5 µV versus 20 µV). Operating temperature range is -40°C to 125°C, which covers the primary operating window but does not extend to the -55°C minimum of the OPA2277MDTEP. Supply voltage range is 4.5V to 40V. These parts are suitable for applications where the extended low-temperature specification is not required.

MC33072DR2G and MC34072DR2G (onsemi): These parts feature enhanced slew rate (13 V/µs versus 0.8 V/µs) and higher gain bandwidth product (4.5 MHz versus 1 MHz). The MC33072DR2G operates from -40°C to 85°C, while the MC34072DR2G operates from 0°C to 70°C. Supply voltage range is 3V to 44V. These parts are suitable for applications requiring higher frequency response but may not meet extended temperature requirements.

OP2177ARZ-REEL and OP2177ARZ-REEL7 (Analog Devices Inc.): These parts maintain similar electrical characteristics to the OPA2277MDTEP with 1.3 MHz gain bandwidth product and 0.7 V/µs slew rate. Operating temperature range is -40°C to 125°C. Supply voltage range is 5V to 30V, which is narrower than the OPA2277MDTEP. These parts are suitable for applications within the specified supply voltage window.

Frequently Asked Questions (FAQ)

Q: Can ISL28207FBZ-T13 or ISL28207FBZ-T7 be used as direct replacements for OPA2277MDTEP?

A: These parts are functionally compatible in 8-SOIC package format and share the 1 MHz gain bandwidth product. However, the operating temperature minimum is -40°C rather than -55°C. Substitution is valid only if the application does not require operation below -40°C.

Q: What is the primary difference between MC33072DR2G and MC34072DR2G?

A: Both parts are electrically identical. The primary difference is operating temperature range: MC33072DR2G operates from -40°C to 85°C, while MC34072DR2G operates from 0°C to 70°C. Select based on required temperature specification.

Q: Are OP2177ARZ-REEL and OP2177ARZ-REEL7 interchangeable?

A: Yes. Both parts are electrically identical dual operational amplifiers in 8-SOIC package. The designation difference reflects packaging reel specifications. Both are suitable substitutes for OPA2277MDTEP within the 5V to 30V supply voltage range.

Q: Why do some substitute parts have higher slew rates than OPA2277MDTEP?

A: MC33072DR2G and MC34072DR2G feature 13 V/µs slew rate compared to 0.8 V/µs for OPA2277MDTEP. Higher slew rate indicates faster output voltage change capability, which may benefit high-frequency applications but is not required for all general-purpose amplifier applications.

Q: What is the significance of the 8-SOIC package specification?

A: The 8-SOIC (Small Outline Integrated Circuit) package with 0.154" width and 3.90mm width is a standard surface mount package. All listed substitute parts use this identical package, ensuring mechanical and electrical compatibility on PCB layouts designed for OPA2277MDTEP.

Q: Which substitute part has the lowest supply current consumption?

A: ISL28207FBZ-T13 and ISL28207FBZ-T7 have the lowest supply current at 210 µA (x2 Channels), compared to 790 µA for OPA2277MDTEP. This makes these parts suitable for power-constrained applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, meeting environmental and regulatory requirements equivalent to OPA2277MDTEP.
