Replacement verdict
Compatible functional replacement candidate
The AMC1300BDWV and AMC1300DWVR are functionally equivalent isolated amplifiers sharing the same core architecture, gain, and input range, differing only in package form factor and reel packaging. The AMC1300DWVR is a valid functional substitute for the AMC1300BDWV where tape-and-reel assembly and the SOIC-8 wide-body footprint are acceptable.

Frequently asked questions
What are the AMC1300BDWV and AMC1300DWVR?
Both are isolated amplifiers from Texas Instruments designed for shunt-based current sensing in high-voltage systems. They provide galvanic isolation between the high-voltage and low-voltage domains and are functionally identical, differing only in packaging and ordering quantity.
What is the difference between the AMC1300BDWV and AMC1300DWVR?
The AMC1300BDWV is supplied in a tube (rail) packaging, while the AMC1300DWVR is supplied in tape-and-reel packaging. Both use the same 8-pin SOIC (DWV) package and are electrically and functionally identical.
Are the AMC1300BDWV and AMC1300DWVR electrically interchangeable?
Yes. Both devices share the same die, pinout, and electrical specifications, including the ±250 mV input range, fixed gain of 8.2, and reinforced isolation rating. The only difference is the shipping packaging format.
What isolation rating do these devices provide?
Both the AMC1300BDWV and AMC1300DWVR are rated for reinforced isolation with a 5 kV RMS isolation voltage for 1 minute per UL 1577, and a 1500 V DC working voltage per VDE V 0884-11.
What is the input voltage range and gain of the AMC1300B?
The AMC1300B accepts a differential input voltage of ±250 mV and provides a fixed gain of 8.2, producing a differential output of ±2.05 V. This makes it suitable for shunt resistor-based current sensing.
What is the supply voltage requirement for the AMC1300BDWV and AMC1300DWVR?
Both devices require a high-side supply (VDD1) of 3.0 V to 5.5 V and a low-side supply (VDD2) of 3.0 V to 5.5 V. The two supplies are isolated from each other.
Which package do the AMC1300BDWV and AMC1300DWVR use?
Both devices use the 8-pin SOIC package with the DWV suffix, which is a wide-body SOIC with 5.85 mm creepage and clearance, supporting reinforced isolation requirements.
Can the AMC1300BDWV and AMC1300DWVR be used interchangeably in a design?
Yes. Since both parts are electrically identical and share the same package and pinout, they can be used interchangeably in the same PCB footprint. The choice between them depends only on the preferred packaging format for manufacturing.
