OPA832IDRG4 Equivalent & Substitute Parts

Part Overview

The OPA832IDRG4 is a voltage feedback operational amplifier manufactured by Texas Instruments, designed for video amplification applications. It features rail-to-rail output capability and is packaged in an 8-SOIC surface mount configuration. The device operates with supply voltages ranging from 2.8V to 11V (single supply) or ±1.4V to ±5.5V (dual supply).

The OPA832IDRG4 is classified as obsolete. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications utilizing this amplifier topology.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the OPA832IDRG4 are identified based on strict electrical and mechanical compatibility criteria. The following parameters determine substitution eligibility:

Primary Compatibility Criteria:

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Output Type: Rail-to-Rail
• Number of Circuits: 1
• Voltage - Supply compatibility: Overlapping or equivalent supply voltage ranges
• Applications: Voltage Feedback amplification

Substitution Categories:

Category 1: Direct Equivalent (Same Base Product) OPA832ID represents the active production equivalent of the obsolete OPA832IDRG4. Both devices share identical electrical specifications, the same base product number (OPA832), and are housed in the 8-SOIC package. The primary difference is packaging format (tube versus tape & reel) and product status (active versus obsolete).

Category 2: Manufacturer-Recommended Alternative AD8051ARZ-REEL is designated as a manufacturer-recommended substitute. While produced by Analog Devices Inc. rather than Texas Instruments, this device meets the core mechanical and electrical requirements for voltage feedback amplification in 8-SOIC packaging. Electrical parameters remain within acceptable ranges for most video amplifier applications, with the exception of slew rate (170 V/µs versus 350 V/µs) and output current capability (45 mA versus 85 mA).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Recommended Primary Option): OPA832ID is the preferred substitute for OPA832IDRG4. Both devices are manufactured by Texas Instruments, share identical electrical specifications, and are housed in the same 8-SOIC package. The OPA832ID is in active production status, ensuring long-term availability and supply chain stability. Selection of OPA832ID requires no circuit redesign or performance trade-offs. Both devices maintain ROHS3 compliance and equivalent moisture sensitivity ratings.

For Alternative Sourcing: AD8051ARZ-REEL may be selected when OPA832ID availability is constrained. This device is manufactured by Analog Devices Inc. and maintains active production status. The AD8051ARZ-REEL is housed in the same 8-SOIC package and supports rail-to-rail output operation. However, the following electrical differences must be evaluated against application requirements:

• Slew rate is reduced from 350 V/µs to 170 V/µs
• Output current capability is reduced from 85 mA to 45 mA
• Bandwidth is increased from 99 MHz to 110 MHz
• Supply voltage span is 3V to 12V (versus 2.8V to 11V single supply)

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original OPA832IDRG4.

Frequently Asked Questions (FAQ)

Q: Can OPA832ID be used as a direct replacement for OPA832IDRG4 without circuit modifications?

A: Yes. OPA832ID is electrically and mechanically identical to OPA832IDRG4. Both devices feature identical bandwidth (99 MHz), slew rate (350 V/µs), output current (85 mA), and supply voltage ranges. The primary difference is product status (active versus obsolete) and packaging format (tube versus tape & reel). No circuit redesign is required.

Q: What are the limitations of using AD8051ARZ-REEL as a substitute?

A: AD8051ARZ-REEL has a lower slew rate (170 V/µs versus 350 V/µs) and reduced output current capability (45 mA versus 85 mA). Applications requiring high-speed transient response or high output current loads may not be suitable for this substitute. The bandwidth is slightly higher (110 MHz versus 99 MHz), which may introduce different frequency response characteristics. Evaluation against specific application requirements is necessary.

Q: Are all substitute parts in the same physical package?

A: Yes. OPA832IDRG4, OPA832ID, and AD8051ARZ-REEL are all housed in 8-SOIC (0.154", 3.90mm Width) surface mount packages. Pin-to-pin compatibility is maintained, allowing direct PCB footprint compatibility.

Q: What is the difference between OPA832IDRG4 and OPA832ID packaging?

A: OPA832IDRG4 is supplied in tape & reel (TR) format, while OPA832ID is supplied in tube packaging. Both devices are identical in electrical performance and physical dimensions. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. OPA832IDRG4, OPA832ID, and AD8051ARZ-REEL are all ROHS3 compliant. All devices are REACH unaffected and carry EAR99 ECCN classification.

Q: What is the moisture sensitivity level difference between substitutes?

A: OPA832IDRG4 and OPA832ID have MSL 2 (1 Year), while AD8051ARZ-REEL has MSL 1 (Unlimited). MSL 1 indicates superior moisture resistance and longer shelf life without baking requirements.
