Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2022IPG4 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Amplifier Type: General Purpose
• Number of Circuits: 2
• Slew Rate: 0.65 V/µs
• Gain Bandwidth Product: 2.8 MHz
• Current - Input Bias: 35 nA
• Voltage - Input Offset: 150 µV
• Current - Supply: 550 µA (x2 Channels)
• Current - Output / Channel: 30 mA
• Voltage - Supply Span: 4 V to 40 V
• Operating Temperature: -40°C ~ 85°C

Mechanical Compatibility Criteria:

• Package / Case: 8-DIP (0.300", 7.62mm) for through-hole mounting
• Pin configuration and footprint compatibility

Substitute parts are grouped into two categories based on packaging format:

Category 1: Through-Hole Package Equivalents Parts maintaining the 8-PDIP package format for direct PCB footprint compatibility.

Category 2: Surface-Mount Package Equivalents Parts with identical electrical specifications but different package formats (8-SOIC), requiring PCB redesign but offering manufacturing advantages.

Category 3: Alternative Amplifier Topologies Parts with different electrical characteristics (voltage feedback vs. general purpose) that may serve similar applications but do not constitute direct electrical equivalents.

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalent (Recommended for Pin-Compatible Substitution):

TLE2022IDR is the manufacturer-recommended substitute for the TLE2022IPG4. This part maintains identical electrical specifications across all critical parameters: slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The TLE2022IDR is currently in active production status with substantial inventory availability (43,002 pieces). Both parts share the same base product number (TLE2022) and comply with ROHS3 and REACH requirements. The primary difference is packaging format: TLE2022IDR uses 8-SOIC surface-mount technology rather than 8-PDIP through-hole mounting. This substitution requires PCB redesign but provides manufacturing advantages including reduced board space and automated assembly compatibility.

Through-Hole Package Alternative (Pin-Compatible Footprint):

AD828ANZ maintains the 8-DIP through-hole package format identical to the TLE2022IPG4, enabling direct PCB footprint compatibility without layout modification. However, this part represents a different amplifier topology (voltage feedback vs. general purpose) with significantly different electrical characteristics. The AD828ANZ exhibits substantially higher slew rate (450 V/µs vs. 0.65 V/µs), higher gain bandwidth product (130 MHz vs. 2.8 MHz), and higher supply current (14 mA vs. 550 µA). These performance differences indicate the AD828ANZ is designed for video and high-frequency applications rather than general-purpose low-power amplification. Selection of AD828ANZ requires circuit analysis to confirm compatibility with application requirements. The part is currently in active production status with 3,200 pieces in inventory and complies with ROHS3 and REACH requirements.

Compliance and Regulatory Status:

All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, consistent with the original TLE2022IPG4. Moisture sensitivity level remains at MSL 1 (Unlimited) for all alternatives. ECCN classification (EAR99) and HTSUS code (8542.33.0001) are identical across all parts.

Frequently Asked Questions (FAQ)

Q: Can TLE2022IDR be used as a direct replacement for TLE2022IPG4 in existing designs?

A: TLE2022IDR provides complete electrical equivalence to TLE2022IPG4 across all specified parameters. However, the package format differs: TLE2022IDR uses 8-SOIC surface-mount technology while TLE2022IPG4 uses 8-PDIP through-hole technology. Direct PCB footprint substitution is not possible without layout redesign. If through-hole mounting is required for the existing PCB, TLE2022IDR cannot be used without board modification.

Q: What are the key differences between TLE2022IPG4 and AD828ANZ?

A: Both parts feature dual circuits in 8-DIP through-hole packages and operate across the -40°C to 85°C temperature range. However, they serve different application classes. TLE2022IPG4 is a general-purpose amplifier with 0.65 V/µs slew rate and 2.8 MHz bandwidth, optimized for low-power, moderate-bandwidth applications. AD828ANZ is a voltage feedback amplifier with 450 V/µs slew rate and 130 MHz bandwidth, designed for video and high-frequency signal processing. Supply current differs significantly: TLE2022IPG4 draws 550 µA while AD828ANZ draws 14 mA. These differences indicate fundamentally different design objectives and application domains.

Q: Is AD828ANZ suitable for applications originally designed for TLE2022IPG4?

A: AD828ANZ is not a direct electrical equivalent and should not be assumed compatible without circuit analysis. The substantially higher slew rate, bandwidth, and supply current indicate different performance characteristics. Applications requiring the specific low-power, moderate-bandwidth profile of TLE2022IPG4 may not function correctly with AD828ANZ. Conversely, applications requiring high-speed video amplification cannot use TLE2022IPG4 or its direct equivalent TLE2022IDR. Selection must be based on application requirements, not package compatibility alone.

Q: What inventory status should influence substitution decisions?

A: TLE2022IPG4 is discontinued at DiGi Electronics with 659 pieces currently in stock. TLE2022IDR is in active production with 43,002 pieces available, providing superior long-term supply security. AD828ANZ is in active production with 3,200 pieces available. For new designs or production planning, TLE2022IDR is the preferred choice due to electrical equivalence and active production status. For existing through-hole designs requiring immediate substitution, AD828ANZ provides package compatibility but requires application verification.

Q: Are there compliance or regulatory differences between these parts?

A: All three parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, MSL 1 (Unlimited), and EAR99 ECCN classification. No regulatory or environmental differences exist between TLE2022IPG4, TLE2022IDR, and AD828ANZ. Substitution decisions should not be influenced by compliance considerations.

Q: What is the significance of the base product number TLE2022?

A: The base product number TLE2022 identifies the core amplifier design. TLE2022IPG4 and TLE2022IDR both use this base number, indicating they are variants of the same amplifier topology with identical electrical specifications. The suffix letters (IPG4 vs. IDR) indicate packaging and distribution format differences. This relationship confirms TLE2022IDR as the manufacturer-recommended substitute for TLE2022IPG4.
