Replacement verdict
Compatible functional replacement candidate
The AMC1300BDWVR and AMC1300DWV are functionally equivalent isolated amplifiers sharing the same core architecture, input range, and package footprint, making them viable substitutes in most designs. The primary distinction lies in the reinforced isolation rating, where the AMC1300BDWVR offers a higher isolation voltage suitable for applications demanding enhanced safety margins. Designers should confirm the required isolation level for their specific application before substituting.

Frequently asked questions
What is the difference between the AMC1300BDWVR and the AMC1300DWV?
Both devices are isolated amplifiers in the AMC1300 family from Texas Instruments with identical core specifications, including a ±250 mV input range, fixed gain of 8.2, and reinforced isolation rated at 5000 V RMS. The primary difference is the ordering variant and packaging format: the AMC1300DWV is supplied in a 16-pin SOIC (DW) tube/rail format, while the AMC1300BDWVR is the same DW package delivered in tape-and-reel (R) format for automated assembly. The "B" designation reflects a device revision/variant identifier per the manufacturer's ordering code.
Are the AMC1300BDWVR and AMC1300DWV electrically and functionally interchangeable?
Yes. Both parts share the same functional block diagram, gain, input range, isolation rating, and pinout in the 16-pin SOIC (DW) package. They differ only in the ordering suffix (tape-and-reel vs. tube) and the revision/variant letter. Designers should confirm the specific revision letter against the current datasheet before substituting in a qualified design.
What package do the AMC1300BDWVR and AMC1300DWV use?
Both devices are offered in a 16-pin SOIC package with the Texas Instruments "DW" body designation. The AMC1300BDWVR adds the "R" suffix indicating tape-and-reel packaging, while the AMC1300DWV is supplied in standard tube/rail packaging.
What is the isolation rating of the AMC1300BDWVR and AMC1300DWV?
Both devices are reinforced isolated amplifiers rated for 5000 V RMS isolation per UL 1577, with a working voltage suitable for high-voltage industrial measurement applications. The isolation barrier is a capacitive double-barrier structure per the manufacturer's datasheet.
What input voltage range and gain do the AMC1300BDWVR and AMC1300DWV support?
Both parts feature a ±250 mV linear input range with a fixed gain of 8.2, making them suited for shunt-based current sensing in motor drives and inverters. The output is a differential signal centered around a common-mode voltage of approximately 1.44 V.
Which part should be selected for high-volume automated PCB assembly?
The AMC1300BDWVR is the appropriate choice for high-volume automated assembly because its tape-and-reel packaging is designed for pick-and-place equipment. The AMC1300DWV in tube/rail format is typically used for prototyping, low-volume runs, or manual assembly.
Do the AMC1300BDWVR and AMC1300DWV share the same pinout?
Yes. Both devices use the identical 16-pin SOIC (DW) pinout, with the same assignment of input, output, and supply pins. This allows PCB layouts designed for one variant to accommodate the other without layout changes, provided the packaging format is compatible with the assembly process.
