TLV2773CDGS Equivalent & Substitute Parts

Part Overview

The TLV2773CDGS is a CMOS dual-channel operational amplifier manufactured by Texas Instruments, designed for rail-to-rail output applications in low-voltage environments. This device integrates two independent amplifier circuits in a 10-VSSOP surface mount package and operates across a 2.5V to 5.5V supply voltage range with an operating temperature range of 0°C to 70°C.

The TLV2773CDGS is designated as Last Time Buy, indicating discontinued production. Identification of equivalent and substitute parts is necessary to ensure continued availability for new designs and ongoing production requirements. The substitute part TLV9052SIDGSR provides functional equivalence with enhanced performance characteristics and active product status.

Substitute Part Grouping Explanation

Substitution of the TLV2773CDGS with the TLV9052SIDGSR is based on the following alignment of critical parameters:

Functional Equivalence Criteria:

• Amplifier Type: Both devices are CMOS operational amplifiers
• Number of Circuits: Both contain 2 independent amplifier circuits
• Output Type: Both feature rail-to-rail output capability
• Package Compatibility: Both use 10-VSSOP supplier device package with identical 10-TFSOP, 10-MSOP physical dimensions (0.118", 3.00mm Width)
• Mounting Type: Both are surface mount devices
• Supply Voltage Overlap: TLV9052SIDGSR supply range (1.8V to 5.5V) encompasses the TLV2773CDGS range (2.5V to 5.5V)
• Compliance: Both are ROHS3 compliant and REACH unaffected

Substitution Limitations:

• Operating temperature range differs: TLV2773CDGS operates 0°C to 70°C; TLV9052SIDGSR operates -40°C to 125°C
• Moisture sensitivity differs: TLV2773CDGS is MSL 1; TLV9052SIDGSR is MSL 2

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TLV9052SIDGSR

The TLV9052SIDGSR is the manufacturer-recommended substitute for the TLV2773CDGS. This substitution is supported by:

• Identical package footprint and pinout compatibility (10-VSSOP)
• Matching dual-channel CMOS rail-to-rail amplifier architecture
• Active product status ensuring long-term availability and supply continuity
• ROHS3 compliance and REACH unaffected status matching the original part
• Enhanced performance characteristics including lower supply current (330µA vs 1mA), lower input offset voltage (330µV vs 700µV), and higher slew rate (15V/µs vs 10.5V/µs)
• Extended operating temperature range (-40°C to 125°C) providing broader application flexibility

Considerations for Substitution:

The TLV9052SIDGSR operates at a minimum supply voltage of 1.8V compared to the TLV2773CDGS minimum of 2.5V. Applications requiring operation below 2.5V require verification of circuit design compatibility. The TLV9052SIDGSR has MSL 2 rating with 1-year moisture sensitivity compared to MSL 1 unlimited for the TLV2773CDGS, requiring adherence to appropriate moisture control procedures during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can the TLV9052SIDGSR be used as a direct replacement for the TLV2773CDGS in existing designs?

A: The TLV9052SIDGSR is pin-compatible and functionally equivalent for applications operating within the overlapping supply voltage range (2.5V to 5.5V) and temperature range (0°C to 70°C). The substitute part offers improved performance specifications. Designs must account for the different moisture sensitivity level (MSL 2 vs MSL 1) in manufacturing and storage procedures.

Q: What are the key differences between these two parts?

A: The primary differences are product status (Last Time Buy vs Active), operating temperature range (-40°C to 125°C vs 0°C to 70°C), supply current consumption (330µA vs 1mA), input offset voltage (330µV vs 700µV), slew rate (15V/µs vs 10.5V/µs), and moisture sensitivity level (MSL 2 vs MSL 1). The TLV9052SIDGSR provides enhanced performance with extended environmental specifications.

Q: Are the package dimensions identical?

A: Yes. Both devices use the 10-VSSOP supplier device package with identical 10-TFSOP, 10-MSOP physical dimensions of 0.118" by 3.00mm width. PCB footprints are directly compatible.

Q: What is the significance of the Last Time Buy status for the TLV2773CDGS?

A: Last Time Buy status indicates that Texas Instruments has discontinued production of the TLV2773CDGS. New designs should transition to the TLV9052SIDGSR to ensure long-term component availability and supply chain continuity.

Q: Does the TLV9052SIDGSR require different handling procedures?

A: The TLV9052SIDGSR has MSL 2 rating with 1-year moisture sensitivity, compared to MSL 1 unlimited for the TLV2773CDGS. This requires adherence to moisture control procedures during storage, with a maximum shelf life of 1 year under specified humidity conditions. Proper baking procedures may be required if moisture absorption limits are exceeded.

Q: Can the TLV9052SIDGSR operate at supply voltages below 2.5V?

A: The TLV9052SIDGSR minimum supply voltage is 1.8V, enabling operation in lower voltage applications. However, designs originally specified for the TLV2773CDGS minimum of 2.5V do not require this extended lower voltage capability. Verification of circuit performance at 1.8V is necessary only for new applications specifically requiring sub-2.5V operation.
