OPA334AIDBVRG4 Equivalent & Substitute Parts

Part Overview

The OPA334AIDBVRG4 is a zero-drift operational amplifier manufactured by Texas Instruments, designed for precision analog signal conditioning applications. This device features rail-to-rail output capability, minimal input offset voltage (1 µV), and low input bias current (70 pA), making it suitable for high-accuracy measurement and instrumentation circuits.

The OPA334AIDBVRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility with the original design specifications.

• Package / Case: SOT-23-6
• Mounting Type: Surface Mount
• Electrical specifications: Slew Rate (1.6 V/µs), Gain Bandwidth Product (2 MHz), Input Bias Current (70 pA), Input Offset Voltage (1 µV), Supply Current (285 µA), Output Current (50 mA), Supply Voltage Range (2.7 V to 5.5 V), Operating Temperature (-40°C to 125°C)
• Compliance: RoHS3 Compliant, Moisture Sensitivity Level 2

Substitute parts must match all critical parameters to ensure functional and mechanical compatibility without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The OPA334AIDBVR is the direct substitute for the discontinued OPA334AIDBVRG4. Both parts are manufactured by Texas Instruments and share identical electrical and mechanical specifications. The primary distinction is product status: the OPA334AIDBVRG4 is discontinued, while the OPA334AIDBVR maintains active status with significantly higher inventory availability (226,225 pieces in stock versus 2,400 pieces for the main part).

Both parts comply with RoHS3 requirements and carry identical moisture sensitivity ratings. The OPA334AIDBVR is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production-volume applications.

For new designs or component replenishment, the OPA334AIDBVR is the appropriate selection. No circuit modifications or design changes are required when transitioning from OPA334AIDBVRG4 to OPA334AIDBVR.

Frequently Asked Questions (FAQ)
