TLV379IDR Equivalent & Substitute Parts

Part Overview

The TLV379IDR is a general-purpose operational amplifier manufactured by Texas Instruments, housed in an 8-SOIC surface mount package. This rail-to-rail output amplifier operates across a supply voltage range of 1.8 V to 5.5 V and is designed for low-power applications requiring single-circuit amplification. The device maintains Active product status and is RoHS3 compliant. Substitute parts are identified when the primary part becomes unavailable, when supply chain constraints occur, or when design requirements necessitate alternative performance characteristics within the same functional category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TLV379IDR is determined by the following mandatory criteria:

Mechanical Compatibility:

• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount
• Pin count and footprint equivalence

Electrical Compatibility:

• Amplifier type: General Purpose
• Number of circuits: 1
• Output type: Rail-to-Rail
• Supply voltage range overlap: Minimum 1.8 V to 5.5 V operation capability
• Operating temperature range: -40°C to 125°C (or compatible subset)

Compliance Requirements:

• RoHS3 compliance
• Active product status

All four substitute parts meet these criteria. Differences in slew rate, gain bandwidth product, input bias current, input offset voltage, and supply current represent performance variations within the general-purpose amplifier category and do not preclude substitution when the application requirements permit.

Engineering Selection Recommendations

TLV379IDR (Primary Part) Select when the extended operating temperature range of -40°C to 125°C is required and when the minimum supply voltage of 1.8 V is necessary for ultra-low-voltage applications. This part is suitable for designs requiring the lowest input bias current specification at 5 pA.

MAX4040ESA+ (Substitute) Select when supply voltage operation begins at 2.4 V or higher and when the operating temperature range of -40°C to 85°C is acceptable. This part offers improved input offset voltage (200 µV) compared to the primary part. Packaging is Tube rather than Tape & Reel.

MCP6141-E/SN (Substitute) Select when the extended operating temperature range of -40°C to 125°C is required and when the minimum supply voltage can be as low as 1.4 V. This part provides the lowest supply current (600 nA) and lowest input bias current (1 pA). Packaging is Tube rather than Tape & Reel.

MCP6141-I/SN (Substitute) Select when the operating temperature range of -40°C to 85°C is acceptable and when the minimum supply voltage can be as low as 1.4 V. This part provides the lowest supply current (600 nA) and lowest input bias current (1 pA). Packaging is Tube rather than Tape & Reel.

MCP6143-I/SN (Substitute) Select when the operating temperature range of -40°C to 85°C is acceptable and when the minimum supply voltage can be as low as 1.4 V. This part provides the lowest supply current (600 nA) and lowest input bias current (1 pA). Packaging is Tube rather than Tape & Reel.

All substitute parts maintain RoHS3 compliance and Active product status. Selection between substitutes depends on specific application requirements for temperature range, minimum supply voltage, and performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can MCP6141-E/SN replace TLV379IDR in all applications?

A: MCP6141-E/SN is mechanically and electrically compatible with TLV379IDR in applications where the operating temperature range of -40°C to 125°C is required. Both parts support the same 8-SOIC package and rail-to-rail output configuration. However, packaging differs: MCP6141-E/SN is supplied in Tube format while TLV379IDR is supplied in Tape & Reel format. Verify that your assembly process accommodates the packaging format.

Q: What is the minimum supply voltage difference between TLV379IDR and MCP6141 variants?

A: TLV379IDR operates at a minimum of 1.8 V, while MCP6141-E/SN, MCP6141-I/SN, and MCP6143-I/SN operate at a minimum of 1.4 V. If your design requires operation below 1.8 V, the MCP6141 or MCP6143 variants are suitable substitutes.

Q: Is MAX4040ESA+ suitable for applications requiring -40°C to 125°C operation?

A: No. MAX4040ESA+ operates across -40°C to 85°C. If your application requires the full -40°C to 125°C temperature range, select TLV379IDR, MCP6141-E/SN, or verify that the 85°C upper limit is acceptable for your design.

Q: Do all substitute parts use the same 8-SOIC package footprint?

A: Yes. All parts listed—TLV379IDR, MAX4040ESA+, MCP6141-E/SN, MCP6141-I/SN, and MCP6143-I/SN—use the 8-SOIC (0.154", 3.90mm Width) package. PCB footprints are identical. Packaging format (Tape & Reel versus Tube) affects supply and handling but not board-level compatibility.

Q: What is the primary performance difference between TLV379IDR and MCP6141-E/SN?

A: MCP6141-E/SN provides lower supply current (600 nA versus 4 µA), lower input bias current (1 pA versus 5 pA), and lower input offset voltage (3 mV versus 800 µV). TLV379IDR supports a lower minimum supply voltage (1.8 V versus 1.4 V) and maintains the extended temperature range to 125°C.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. TLV379IDR, MAX4040ESA+, MCP6141-E/SN, MCP6141-I/SN, and MCP6143-I/SN are all RoHS3 compliant and maintain Active product status.
