TLV2404IDRG4 Equivalent & Substitute Parts

Part Overview

The TLV2404IDRG4 is a general-purpose operational amplifier integrated circuit manufactured by Texas Instruments, featuring four independent amplifier circuits in a 14-SOIC surface mount package. This device is designed for rail-to-rail output operation across a wide supply voltage range of 2.5 V to 16 V, making it suitable for low-power analog signal processing applications.

The TLV2404IDRG4 is currently discontinued at DiGi Electronics. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production requirements. Substitute parts must maintain functional compatibility through matching package type, pin configuration, electrical performance parameters, and operating specifications.

Primary Compatibility Criteria:

• Package type: 14-SOIC surface mount configuration
• Number of circuits: 4 independent amplifier channels
• Output type: Rail-to-Rail capability
• Supply voltage range: Minimum 2.5 V, Maximum 16 V or greater
• Operating temperature range: -40°C ~ 125°C or broader
• Mounting type: Surface Mount
• RoHS3 compliance and MSL Level 1 rating

Substitute Categories:

Category 1 - Direct Functional Equivalent (Same Base Product): TLV2404IDR represents the same base product as TLV2404IDRG4, differing only in packaging format (Tape & Reel versus tube packaging). This part maintains identical electrical specifications and is functionally interchangeable.

Category 2 - Functional Substitutes (Alternative Manufacturers): AD8548ARZ and AD8659ARZ are CMOS-based four-circuit amplifiers from Analog Devices Inc. These parts share the same 14-SOIC package, four-circuit configuration, rail-to-rail output, and compatible supply voltage ranges. While amplifier type differs (CMOS versus General Purpose), electrical performance parameters remain within acceptable substitution boundaries for general-purpose applications.

Engineering Selection Recommendations

Primary Recommendation: TLV2404IDR

The TLV2404IDR is the preferred substitute for the discontinued TLV2404IDRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and supply voltage range. The only difference is packaging format: TLV2404IDR is supplied in Tape & Reel format while TLV2404IDRG4 was supplied in tube packaging. TLV2404IDR maintains active product status and is currently in stock with 1685 pieces available. This part is ROHS3 compliant and carries MSL Level 1 rating, matching the original part's compliance profile.

Secondary Recommendations: AD8548ARZ and AD8659ARZ

AD8548ARZ and AD8659ARZ from Analog Devices Inc. are functional substitutes suitable for applications where the TLV2404IDR is unavailable. Both parts maintain the same 14-SOIC package configuration, four-circuit architecture, rail-to-rail output capability, and compatible operating temperature range. These CMOS-based amplifiers offer enhanced performance characteristics compared to the TLV2404IDRG4, including higher slew rate (0.08 V/µs versus 0.0025 V/µs), higher gain bandwidth product (200 kHz versus 5.5 kHz), lower input bias current (5 pA versus 100 pA), and higher output current per channel (12 mA versus 200 µA). Supply voltage ranges are compatible, with AD8548ARZ and AD8659ARZ supporting 2.7 V to 18 V operation. Both parts are active products with substantial inventory availability (2200 and 3572 pieces respectively) and maintain ROHS3 compliance and MSL Level 1 rating.

Compliance Verification:

All recommended substitute parts maintain ROHS3 compliance and MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with existing manufacturing and storage protocols. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001, maintaining consistent regulatory classification.

Frequently Asked Questions (FAQ)

Q1: Can TLV2404IDR be used as a direct replacement for TLV2404IDRG4?

A: Yes. TLV2404IDR is a direct functional equivalent of TLV2404IDRG4. Both parts are manufactured by Texas Instruments and possess identical electrical specifications. The only difference is packaging format: TLV2404IDR is supplied in Tape & Reel format while TLV2404IDRG4 was supplied in tube packaging. Pin configuration, package dimensions (14-SOIC), and all electrical parameters are identical.

Q2: What are the key differences between TLV2404IDRG4 and the Analog Devices substitutes?

A: The primary differences are manufacturer and amplifier technology. TLV2404IDRG4 is a general-purpose amplifier, while AD8548ARZ and AD8659ARZ are CMOS-based amplifiers. The Analog Devices parts offer higher performance: slew rate of 0.08 V/µs (versus 0.0025 V/µs), gain bandwidth product of 200 kHz (versus 5.5 kHz), and lower input bias current of 5 pA (versus 100 pA). All parts share the same 14-SOIC package, four-circuit configuration, rail-to-rail output, and compatible supply voltage ranges.

Q3: Are all substitute parts compatible with the same PCB layout?

A: Yes. All substitute parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package with identical pin configuration. PCB layouts designed for TLV2404IDRG4 are compatible with TLV2404IDR, AD8548ARZ, and AD8659ARZ without modification.

Q4: What is the difference between AD8548ARZ and AD8659ARZ?

A: Both parts are CMOS four-circuit amplifiers in 14-SOIC packages with identical electrical performance in most parameters. The primary difference is input offset voltage: AD8659ARZ specifies 350 µV while AD8548ARZ specifies 3 mV. For applications requiring lower input offset voltage, AD8659ARZ is the preferred choice.

Q5: Do all substitute parts meet the same compliance requirements?

A: Yes. All substitute parts (TLV2404IDR, AD8548ARZ, and AD8659ARZ) are ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating. All parts are classified under ECCN EAR99 and HTSUS 8542.33.0001, maintaining consistent regulatory classification with the original TLV2404IDRG4.

Q6: Which substitute should be selected for low-power applications?

A: TLV2404IDR is the optimal choice for low-power applications. It maintains the original TLV2404IDRG4 supply current specification of 900 nA per four channels. AD8548ARZ and AD8659ARZ consume 18 µA per four channels, representing a 20-fold increase in supply current. For power-sensitive designs, TLV2404IDR is the preferred substitute.

Q7: Which substitute should be selected for high-speed applications?

A: AD8548ARZ and AD8659ARZ are suitable for applications requiring higher bandwidth performance. These CMOS amplifiers offer gain bandwidth product of 200 kHz and slew rate of 0.08 V/µs, compared to 5.5 kHz and 0.0025 V/µs for TLV2404IDRG4. For signal processing applications requiring faster response times, the Analog Devices substitutes provide enhanced performance.
