CA3260EZ Equivalent & Substitute Parts

Part Overview

The CA3260EZ is a CMOS dual-channel operational amplifier manufactured by Renesas Electronics Corporation in an 8-DIP through-hole package. This device is classified as a linear amplifier with two independent circuits suitable for general-purpose analog signal processing applications. The CA3260EZ is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and component procurement. Substitute parts must maintain functional compatibility through matching package type, circuit count, amplifier topology, and electrical operating parameters within acceptable ranges.

Engineering Selection Recommendations

CMOS Amplifier Substitutes (Direct Topology Match):

TLC272IP and TLC272CP are CMOS amplifiers manufactured by Texas Instruments with identical dual-circuit, 8-DIP through-hole configuration. Both parts are ROHS3 compliant and REACH unaffected. TLC272IP operates across -40°C to 85°C and is active product status. TLC272CP operates across 0°C to 70°C and is active product status. These parts exhibit lower input bias current (0.7 pA) and lower input offset voltage (0.9–1.1 mV) compared to the CA3260EZ. However, slew rate is reduced to 5.3 V/µs and gain bandwidth product is reduced to 2.2 MHz. Supply current is significantly lower at 1.4–1.9 mA. Output current per channel is reduced to 30 mA. Selection between TLC272IP and TLC272CP depends on operating temperature requirements.

General-Purpose Amplifier Substitutes (Enhanced Performance):

TLC082IP, TLC082AIP, TLC082CP, TLC072IP, and TLC072AIP are general-purpose amplifiers manufactured by Texas Instruments. All maintain 8-DIP through-hole packaging and dual-circuit configuration with ROHS3 compliance and REACH unaffected status. These parts provide enhanced slew rate (19 V/µs) and gain bandwidth product (10 MHz) compared to the CA3260EZ. Output current per channel is increased to 57 mA. Supply current ranges from 1.9 to 2.1 mA. Input offset voltage is significantly lower at 0.39 mV. Temperature range varies by part number: TLC082IP, TLC082AIP, TLC072IP, and TLC072AIP operate across -40°C to 125°C (matching CA3260EZ range); TLC082CP and TLC072CP operate across 0°C to 70°C. Product status varies: TLC082IP, TLC082AIP, TLC072IP, and TLC072AIP are Last Time Buy; TLC082CP and TLC072CP are Active.

Selection Criteria:

For applications requiring CMOS topology preservation with lower power consumption, select TLC272IP (active, extended temperature) or TLC272CP (active, commercial temperature).

For applications tolerating general-purpose amplifier topology with enhanced performance specifications, select TLC082IP or TLC072IP (extended temperature range, last time buy status) or TLC082CP or TLC072CP (commercial temperature range, active status).

Temperature range compatibility is critical: CA3260EZ operates to -55°C minimum; TLC272IP extends to -40°C; TLC272CP and TLC082CP/TLC072CP are limited to 0°C minimum.

Frequently Asked Questions (FAQ)

Q: Can TLC272IP directly replace CA3260EZ in all applications?

A: TLC272IP maintains identical package type (8-DIP through-hole), circuit count (2), and amplifier topology (CMOS). Electrical parameters are compatible within the specified ranges. However, slew rate is reduced from 10 V/µs to 5.3 V/µs, and gain bandwidth product is reduced from 4 MHz to 2.2 MHz. Applications sensitive to these performance metrics require evaluation. Operating temperature range differs: TLC272IP operates -40°C to 85°C versus CA3260EZ -55°C to 125°C.

Q: What is the difference between TLC082IP and TLC072IP?

A: Both are general-purpose dual-channel amplifiers in 8-DIP through-hole packages with identical electrical specifications. TLC082IP exhibits input bias current of 3 pA and supply current of 1.9 mA per dual-channel configuration. TLC072IP exhibits input bias current of 1.5 pA and supply current of 2.1 mA per dual-channel configuration. Both operate across -40°C to 125°C and are last time buy status.

Q: Why is slew rate important for substitution?

A: Slew rate determines the maximum rate of change of output voltage per unit time. CA3260EZ specifies 10 V/µs. TLC272 series provides 5.3 V/µs, while TLC082/TLC072 series provide 19 V/µs. Applications requiring fast transient response or high-frequency signal processing may be affected by reduced slew rate. Conversely, enhanced slew rate in general-purpose substitutes improves performance in these applications.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (TLC272IP, TLC272CP, TLC082IP, TLC082AIP, TLC082CP, TLC072IP, TLC072AIP) are ROHS3 compliant and REACH unaffected, matching the compliance status of CA3260EZ.

Q: What is the significance of product status (Active vs. Last Time Buy)?

A: Active status indicates ongoing production and availability. Last Time Buy status indicates limited remaining inventory and discontinued production. TLC272IP and TLC272CP are active. TLC082IP, TLC082AIP, TLC072IP, and TLC072AIP are last time buy. TLC082CP and TLC072CP are active. For long-term supply chain planning, active parts are preferred.

Q: Can I use TLC082CP in place of TLC082IP?

A: Both are identical except for operating temperature range. TLC082CP operates 0°C to 70°C (commercial); TLC082IP operates -40°C to 125°C (industrial). Substitution is valid only if the application operates within the commercial temperature range. Electrical specifications, package type, and circuit count are identical.

Q: What is the impact of reduced output current in TLC272 series?

A: CA3260EZ provides 45 mA per channel; TLC272 series provides 30 mA per channel. Applications requiring high output current drive capability may require external buffering or alternative parts. TLC082/TLC072 series provide 57 mA per channel, exceeding CA3260EZ capability.

Q: How do I determine which substitute is best for my application?

A: Evaluate three factors: (1) Operating temperature range required; (2) Slew rate and gain bandwidth product requirements; (3) Output current requirements. For CMOS topology preservation with lower power consumption, select TLC272 series. For enhanced performance with general-purpose topology, select TLC082 or TLC072 series. Verify temperature range compatibility with application requirements.
