TL064CPW Equivalent & Substitute Parts

Part Overview

The TL064CPW is a J-FET input operational amplifier containing four independent circuits in a 14-TSSOP surface mount package, manufactured by Texas Instruments. This device is classified as Last Time Buy, indicating discontinued production with limited inventory availability. The TL064CPW operates across a 10V to 30V supply span with a slew rate of 3.5V/µs and 1 MHz gain bandwidth product, designed for applications requiring low input bias current and low input offset voltage characteristics inherent to J-FET amplifier topology.

Due to Last Time Buy status and finite inventory (3000 pieces), identification of equivalent substitute parts is necessary for design continuity and long-term component sourcing strategy.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL064CPW is determined by the following critical parameters: package type (14-TSSOP surface mount), circuit count (4 independent amplifiers), and electrical operating characteristics within the specified supply voltage range (10V to 30V minimum).

The substitute parts are grouped into two categories:

Category 1: Direct Packaging Equivalent The TL064CPWR maintains identical J-FET amplifier topology, electrical specifications, and 14-TSSOP package configuration. This substitute differs only in packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Last Time Buy), with significantly higher inventory availability (94,942 pieces).

Category 2: Functional Equivalents with Extended Specifications The ADA4077-4ARUZ, ADA4077-4ARUZ-R7, and ADA4077-4ARUZ-RL represent general-purpose amplifier alternatives that maintain the 14-TSSOP package and four-circuit configuration. These parts operate within the TL064CPW supply voltage range and provide enhanced electrical performance characteristics, including extended operating temperature range (-40°C to 125°C versus 0°C to 70°C) and improved gain bandwidth product (3.6 MHz versus 1 MHz).

Parameter Comparison

Engineering Selection Recommendations

TL064CPWR Selection The TL064CPWR is the primary substitute for the TL064CPW. Both parts maintain identical electrical specifications, J-FET amplifier topology, and 14-TSSOP package configuration. The TL064CPWR is classified as Active product status with substantially higher inventory (94,942 pieces), ensuring long-term availability. This part is suitable for direct replacement in applications where the original TL064CPW specifications are required. Both parts are ROHS3 compliant with MSL 1 rating.

ADA4077-4ARUZ, ADA4077-4ARUZ-R7, and ADA4077-4ARUZ-RL Selection These Analog Devices parts are functional equivalents suitable for applications where extended operating temperature range (-40°C to 125°C) and improved gain bandwidth product (3.6 MHz) are beneficial. All three variants maintain the 14-TSSOP package and four-circuit configuration. The ADA4077-4ARUZ-R7 and ADA4077-4ARUZ-RL differ only in packaging format (Tape & Reel versus Tube), with ADA4077-4ARUZ-RL offering the highest inventory availability (5818 pieces). All three variants are Active product status and ROHS3 compliant with MSL 1 rating.

Selection between these three ADA4077 variants depends on packaging requirements and assembly process compatibility. The ADA4077 series exhibits lower input bias current (400 pA versus 30 pA) and lower output current per channel (10 mA versus 20 mA) compared to the TL064 series, requiring circuit design verification for applications with specific output drive requirements.

Frequently Asked Questions (FAQ)

Q: Can the TL064CPWR be used as a direct replacement for the TL064CPW?

A: Yes. The TL064CPWR provides identical electrical specifications and J-FET amplifier topology within the same 14-TSSOP package. The only differences are packaging format (Cut Tape & Digi-Reel versus Tube) and product status (Active versus Last Time Buy). Both parts operate across the 10V to 30V supply range with identical slew rate (3.5V/µs), gain bandwidth product (1 MHz), input bias current (30 pA), and output current per channel (20 mA).

Q: What are the key differences between the TL064 and ADA4077 series?

A: The TL064CPW uses J-FET amplifier topology, while the ADA4077 series uses general-purpose amplifier topology. The ADA4077 provides extended operating temperature range (-40°C to 125°C versus 0°C to 70°C), higher gain bandwidth product (3.6 MHz versus 1 MHz), and lower input offset voltage (15 µV versus 3 mV). However, the ADA4077 exhibits higher input bias current (400 pA versus 30 pA) and lower output current per channel (10 mA versus 20 mA). Both maintain the 14-TSSOP package and four-circuit configuration.

Q: Which substitute part should be selected for applications requiring maximum output current?

A: The TL064CPWR is the appropriate selection, as it maintains the TL064CPW output current specification of 20 mA per channel. The ADA4077 series provides only 10 mA per channel output current, which may be insufficient for applications requiring higher output drive capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The TL064CPWR, ADA4077-4ARUZ, ADA4077-4ARUZ-R7, and ADA4077-4ARUZ-RL are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). All parts are REACH Unaffected and classified under ECCN EAR99.

Q: What is the difference between ADA4077-4ARUZ, ADA4077-4ARUZ-R7, and ADA4077-4ARUZ-RL?

A: These three parts are electrically identical. The differences are in packaging format: ADA4077-4ARUZ is supplied in Tube packaging, while ADA4077-4ARUZ-R7 and ADA4077-4ARUZ-RL are supplied in Tape & Reel format. Selection depends on assembly process requirements and equipment compatibility. All three variants are Active product status with comparable inventory availability (6402, 6660, and 5818 pieces respectively).

Q: Can the ADA4077 series be used in applications originally designed for the TL064?

A: The ADA4077 series maintains package compatibility (14-TSSOP) and four-circuit configuration, enabling physical and electrical integration into existing designs. However, circuit design verification is required due to differences in input bias current (400 pA versus 30 pA), output current per channel (10 mA versus 20 mA), slew rate (1.2V/µs versus 3.5V/µs), and gain bandwidth product (3.6 MHz versus 1 MHz). Applications with strict output drive requirements or low input bias current specifications may require design modification.

Q: What is the minimum supply voltage for each substitute part?

A: The TL064CPWR requires a minimum supply voltage of 10V, identical to the TL064CPW. The ADA4077 series (all variants) operates with a minimum supply voltage of 5V, providing greater flexibility for lower voltage applications. Maximum supply voltage is 30V for all parts.
