Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLE2022IP is determined by strict adherence to the following criteria:

Primary Substitution Criteria:

• Number of circuits: 2 independent amplifier circuits
• Amplifier classification: General purpose or video feedback topology
• Package compatibility: 8-DIP through-hole form factor (0.300", 7.62mm)
• Supply voltage range: Minimum 4V to maximum 40V capability
• Operating temperature: -40°C to 85°C range
• RoHS3 compliance and REACH unaffected status

Substitute Parts Identified:

1. TLE2022IDR (Texas Instruments) - Direct functional equivalent with identical electrical specifications. Differs only in packaging format (8-SOIC surface mount) and product status (Active vs. Last Time Buy). Electrical parameters are identical.

2. AD812ANZ (Analog Devices Inc.) - Current feedback topology with 2 circuits in 8-DIP through-hole package. Provides higher bandwidth (145 MHz) and slew rate (1600V/µs) compared to TLE2022IP. Supply voltage range: 2.4V to 36V (single) or ±1.2V to ±18V (dual). Active product status with higher inventory availability.

3. AD828ANZ (Analog Devices Inc.) - Voltage feedback topology with 2 circuits in 8-DIP through-hole package. Provides higher bandwidth (130 MHz) and slew rate (450V/µs). Supply voltage range: 5V to 36V (single) or ±2.5V to ±18V (dual). Active product status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Functional Replacement (Identical Electrical Performance):

The TLE2022IDR is the manufacturer-recommended direct substitute for the TLE2022IP. Both devices share identical electrical specifications including slew rate (0.65V/µs), gain bandwidth product (2.8 MHz), input bias current (35 nA), and input offset voltage (150 µV). The TLE2022IDR maintains the same supply voltage range (4V to 40V) and operating temperature range (-40°C to 85°C). The primary difference is packaging format: TLE2022IDR uses 8-SOIC surface mount versus the through-hole 8-DIP of the TLE2022IP. Both are ROHS3 compliant and REACH unaffected. The TLE2022IDR has active product status with significantly higher inventory (43,002 pcs) compared to the TLE2022IP (1,129 pcs, Last Time Buy).

For Higher Performance Applications (Increased Bandwidth and Slew Rate):

The AD812ANZ and AD828ANZ are active Analog Devices alternatives suitable for applications requiring enhanced dynamic performance. Both maintain the 8-DIP through-hole package format and dual-circuit configuration. The AD812ANZ (current feedback topology) provides 145 MHz bandwidth and 1600V/µs slew rate, while the AD828ANZ (voltage feedback topology) provides 130 MHz bandwidth and 450V/µs slew rate. Both devices support the required operating temperature range (-40°C to 85°C) and are ROHS3 compliant and REACH unaffected. Supply voltage ranges differ: AD812ANZ operates from 2.4V to 36V (single) or ±1.2V to ±18V (dual); AD828ANZ operates from 5V to 36V (single) or ±2.5V to ±18V (dual). These substitutes are appropriate only when circuit design accommodates the higher bandwidth and slew rate characteristics.

Compliance and Regulatory Considerations:

All identified substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory continuity. All devices are classified under HTSUS 8542.33.0001 and ECCN EAR99, maintaining consistent export and import classification.

Frequently Asked Questions (FAQ)

Q1: Can TLE2022IDR be used as a direct replacement for TLE2022IP in existing through-hole PCB designs?

A: TLE2022IDR cannot be directly soldered into through-hole PCB footprints designed for TLE2022IP. TLE2022IDR uses 8-SOIC surface mount packaging (0.154" width) while TLE2022IP uses 8-DIP through-hole packaging (0.300" width). PCB redesign or adapter solutions are required. For through-hole applications, AD812ANZ or AD828ANZ are appropriate alternatives.

Q2: What are the key differences between AD812ANZ and AD828ANZ substitutes?

A: AD812ANZ uses current feedback topology with 145 MHz bandwidth and 1600V/µs slew rate, consuming 4.5 mA supply current. AD828ANZ uses voltage feedback topology with 130 MHz bandwidth and 450V/µs slew rate, consuming 14 mA supply current. Current feedback (AD812ANZ) is optimized for high-speed, high-impedance applications, while voltage feedback (AD828ANZ) is optimized for precision and stability. Selection depends on specific application requirements.

Q3: Are the supply voltage ranges of AD812ANZ and AD828ANZ compatible with TLE2022IP circuit designs?

A: Partial compatibility exists. TLE2022IP operates from 4V to 40V single supply. AD812ANZ minimum single supply is 2.4V (lower) and maximum is 36V (lower than TLE2022IP). AD828ANZ minimum single supply is 5V (higher) and maximum is 36V (lower than TLE2022IP). Designs operating at 5V to 36V single supply are compatible with both alternatives. Designs requiring 36V to 40V operation are not compatible with either Analog Devices substitute.

Q4: What is the significance of the TLE2022IP "Last Time Buy" status?

A: Last Time Buy designation indicates Texas Instruments has discontinued production of TLE2022IP. Current inventory (1,129 pcs) represents the final available stock. Once depleted, the device will no longer be available from the manufacturer. Immediate substitution planning is necessary for long-term product support and design continuity.

Q5: Do all substitute parts maintain the same input bias current and input offset voltage specifications?

A: No. TLE2022IP and TLE2022IDR both specify 35 nA input bias current and 150 µV input offset voltage. AD812ANZ and AD828ANZ do not provide these specifications in the available data, indicating different input stage designs. Applications requiring precise input bias current and offset voltage control must use TLE2022IDR or remain with TLE2022IP inventory.

Q6: Can AD812ANZ or AD828ANZ be used in low-frequency, low-power applications designed for TLE2022IP?

A: Electrical substitution is possible from a functional standpoint, as both alternatives provide dual-circuit 8-DIP through-hole packages with compatible operating temperature ranges. However, AD812ANZ and AD828ANZ consume significantly higher supply current (4.5 mA and 14 mA respectively versus 550 µA for TLE2022IP), making them unsuitable for power-constrained applications. Circuit redesign to accommodate higher power consumption may be necessary.

Q7: What packaging considerations apply when selecting between TLE2022IP, TLE2022IDR, AD812ANZ, and AD828ANZ?

A: TLE2022IP, AD812ANZ, and AD828ANZ all use 8-DIP through-hole packaging (0.300", 7.62mm) compatible with existing through-hole PCB designs. TLE2022IDR uses 8-SOIC surface mount packaging (0.154", 3.90mm width) requiring PCB redesign or adapter solutions. For direct PCB compatibility without redesign, select from TLE2022IP, AD812ANZ, or AD828ANZ.
