TLV2322IPWR Equivalent & Substitute Parts

Part Overview

The TLV2322IPWR is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, packaged in 8-TSSOP surface mount configuration. This device belongs to the LinCMOS™ series and is designed for low-power analog signal processing applications requiring dual amplifier circuits in compact form factors.

The TLV2322IPWR carries a Last Time Buy product status, indicating that Texas Instruments has discontinued active production. This status necessitates identification of equivalent substitute components to ensure design continuity and procurement availability for new production runs and long-term support.

Substitute Part Grouping Explanation

Substitution eligibility for the TLV2322IPWR is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Amplifier type: CMOS
• Number of circuits: 2
• Slew rate: 0.03 V/µs
• Gain bandwidth product: 85 kHz
• Input bias current: 0.6 pA
• Input offset voltage: 1.1 mV
• Supply current per channel: 20 µA
• Output current per channel: 30 mA
• Supply voltage range: 2 V to 8 V
• Operating temperature range: -40°C to 85°C

Mechanical Equivalence Criteria:

• Surface mount technology
• 8-pin package configuration
• Base product number: TLV2322

Compliance Equivalence Criteria:

• RoHS3 compliance
• Moisture sensitivity level 1
• REACH unaffected status

The TLV2322IDR qualifies as a direct substitute based on identical electrical specifications and compliance certifications. The primary difference is packaging format: the substitute uses 8-SOIC instead of 8-TSSOP, which affects board layout and thermal characteristics but maintains full electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLV2322IDR

The TLV2322IDR is the manufacturer-recommended substitute for the TLV2322IPWR. This recommendation is based on:

1. Electrical Equivalence: All electrical parameters are identical, including amplifier type, circuit count, slew rate, gain bandwidth product, bias current, offset voltage, supply current, output current, and supply voltage range.

2. Compliance Alignment: Both devices maintain ROHS3 compliance, moisture sensitivity level 1, and REACH unaffected status, ensuring regulatory continuity.

3. Product Status Advantage: The TLV2322IDR carries Active product status with 6215 units in stock, providing long-term availability compared to the Last Time Buy status of the TLV2322IPWR.

4. Package Consideration: The TLV2322IDR uses 8-SOIC packaging instead of 8-TSSOP. This difference requires PCB layout modification but does not affect electrical performance. The 8-SOIC package is 0.154" wide (versus 0.173" for 8-TSSOP), resulting in a more compact footprint.

5. Base Product Equivalence: Both devices share the TLV2322 base product number, confirming they are variants of the same core design.

Frequently Asked Questions (FAQ)

Q1: Can the TLV2322IDR be used as a direct pin-for-pin replacement for the TLV2322IPWR?

A: The TLV2322IDR is electrically equivalent but requires PCB layout modification due to package format differences. The 8-TSSOP and 8-SOIC packages have different physical dimensions and pin spacing. Pin-to-pin functionality is identical, but the printed circuit board footprint must be redesigned to accommodate the 8-SOIC package.

Q2: What is the primary reason for substituting the TLV2322IPWR?

A: The TLV2322IPWR has reached Last Time Buy status, indicating Texas Instruments has discontinued active production. The TLV2322IDR, with Active product status and higher inventory levels, ensures continued component availability for production and long-term support.

Q3: Are there any electrical performance differences between the TLV2322IPWR and TLV2322IDR?

A: No. All electrical specifications are identical, including slew rate, gain bandwidth product, input bias current, input offset voltage, supply current, output current, and operating temperature range. The devices are functionally equivalent.

Q4: How do the package dimensions affect thermal performance?

A: The 8-SOIC package (0.154" width) is more compact than the 8-TSSOP package (0.173" width). Thermal characteristics may differ slightly due to package geometry, but both packages are rated for the same operating temperature range (-40°C to 85°C). Thermal analysis should be performed for specific application requirements.

Q5: Are compliance certifications maintained with the TLV2322IDR?

A: Yes. The TLV2322IDR maintains ROHS3 compliance, moisture sensitivity level 1, and REACH unaffected status, identical to the TLV2322IPWR. No compliance changes occur with substitution.

Q6: What inventory considerations should guide the substitution decision?

A: The TLV2322IPWR has 699 units in stock with Last Time Buy status, indicating limited future availability. The TLV2322IDR has 6215 units in stock with Active product status, providing significantly greater availability for current and future production requirements.

Q7: Is the TLV2322IDR the only available substitute?

A: Based on the provided substitute list, the TLV2322IDR is the manufacturer-recommended equivalent. It is the only substitute listed that meets all electrical and compliance equivalence criteria.
