TLV2404AIN Equivalent & Substitute Parts

Part Overview

The TLV2404AIN is a general purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-DIP through-hole package. This device is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The TLV2404AIN operates across a wide supply voltage range of 2.5V to 16V with rail-to-rail output capability, suitable for low-power analog signal processing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLV2404AIN are selected based on strict compatibility criteria within the operational amplifier category. The primary substitution parameters are:

Mandatory Compatibility Criteria:

• Four independent circuits in single package
• Rail-to-rail output configuration
• 14-DIP through-hole package format
• Supply voltage range overlap with original specification
• RoHS3 compliance and MSL Level 1 rating

Identified Substitute Parts:

1. LMC6464BIN/NOPB (Texas Instruments) — CMOS amplifier variant with enhanced performance characteristics
2. LT1496CN#PBF (Analog Devices Inc.) — General purpose amplifier with extended supply voltage range

Both substitutes maintain the core package and circuit count specifications while offering different performance trade-offs in slew rate, gain bandwidth product, and supply current characteristics.

Parameter Comparison

Engineering Selection Recommendations

LMC6464BIN/NOPB Selection Criteria:

The LMC6464BIN/NOPB is suitable for applications requiring higher slew rate (0.028V/µs versus 0.0025V/µs) and increased gain bandwidth product (50kHz versus 5.5kHz). This CMOS variant exhibits significantly lower input bias current (0.15pA versus 100pA) and reduced supply current consumption (90µA total versus 900nA total). The minimum supply voltage requirement increases to 3V, which may restrict use in ultra-low voltage applications. Product status is Last Time Buy, indicating limited future availability. Operating temperature range is reduced to -40°C to 85°C.

LT1496CN#PBF Selection Criteria:

The LT1496CN#PBF from Analog Devices Inc. maintains active product status, ensuring long-term availability and support. This device offers the widest supply voltage range (2.2V to 36V), accommodating both lower and higher voltage system designs. The extremely low supply current (1µA total) and minimal output current per channel (1.5mA) make this option optimal for ultra-low-power applications. Trade-offs include the lowest slew rate (0.001V/µs) and gain bandwidth product (2.7kHz), restricting use in high-frequency signal processing. Operating temperature range is limited to 0°C to 70°C, narrower than the original part.

Compliance and Certification:

All three parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with modern manufacturing and environmental standards. REACH status is unaffected for all variants.

Frequently Asked Questions (FAQ)

Q: Can LMC6464BIN/NOPB directly replace TLV2404AIN in existing PCB designs?

A: Yes, direct pin-compatible replacement is possible due to identical 14-DIP package configuration and pinout. However, verify that the minimum supply voltage requirement of 3V (versus 2.5V for TLV2404AIN) is compatible with your power supply design. The increased slew rate and gain bandwidth product may alter circuit behavior in high-frequency applications.

Q: What are the key differences between LT1496CN#PBF and the original TLV2404AIN?

A: The LT1496CN#PBF offers extended supply voltage range (2.2V to 36V), significantly lower supply current consumption, and active product status. However, it exhibits lower slew rate and gain bandwidth product, making it unsuitable for applications requiring fast signal transitions or high-frequency operation. Operating temperature range is narrower (0°C to 70°C versus -40°C to 125°C).

Q: Which substitute part is recommended for low-power battery-operated applications?

A: The LT1496CN#PBF is optimal for battery-powered designs, consuming only 1µA total supply current across four channels. This represents a 900-fold reduction compared to the TLV2404AIN. The extended maximum supply voltage (36V) also accommodates multi-cell battery configurations.

Q: Is the LMC6464BIN/NOPB suitable for high-speed signal conditioning?

A: The LMC6464BIN/NOPB provides improved high-frequency performance with 50kHz gain bandwidth product and 0.028V/µs slew rate, compared to 5.5kHz and 0.0025V/µs for the original part. However, this remains a low-bandwidth device. For applications requiring slew rates exceeding 1V/µs or bandwidth above 1MHz, alternative amplifier families should be evaluated.

Q: What is the impact of the reduced operating temperature range in substitute parts?

A: The LMC6464BIN/NOPB operates to 85°C maximum (versus 125°C), and the LT1496CN#PBF to 70°C maximum. Applications requiring operation above these temperatures cannot use these substitutes. Verify your system's maximum junction temperature requirements before selection.

Q: Are all substitute parts available in the same packaging options?

A: All three parts are available in 14-DIP through-hole package format. The LMC6464BIN/NOPB is supplied in tube packaging, while the LT1496CN#PBF is also tube-packaged. Verify packaging and tape-and-reel availability with your supplier if automated assembly is required.

Q: Can I use LT1496CN#PBF in applications originally designed for TLV2404AIN operating at 16V supply?

A: Yes. The LT1496CN#PBF maximum supply voltage is 36V, exceeding the 16V requirement. However, verify that the lower slew rate (0.001V/µs) and gain bandwidth product (2.7kHz) do not compromise circuit performance in your specific application.
