|---|---|---|---|
| Manufacturer | Texas Instruments | Texas Instruments | Same manufacturer ensures identical silicon design and qualification standards. |
| Function | Isolated amplifier (precision isolation amplifier) | Isolated amplifier (precision isolation amplifier) | Identical function confirms the parts are functionally interchangeable in signal isolation circuits. |
| Package / Case | SOIC-8 (8-SOIC, 5.85mm body) | SOIC-8 (8-SOIC, 5.85mm body) | Same package footprint allows drop-in PCB replacement without layout changes. |
| Number of Channels | 1 | 1 | Channel count must match for the circuit to provide the required single isolated signal path. |
| Isolation Voltage (VISO) | 4250 Vpeak (per UL1577) | 4250 Vpeak (per UL1577) | Isolation rating is critical for safety and noise immunity in high-voltage measurement applications. |
| Supply Voltage Range | 4.5 V to 5.5 V | 4.5 V to 5.5 V | Matching supply range ensures compatibility with the same power rail design. |
| Gain | 8 V/V (fixed) | 8 V/V (fixed) | Fixed gain of 8 determines the signal scaling; identical gain preserves measurement accuracy. |

Frequently asked questions
What is the difference between the AMC1200BDWVR and the AMC1200BDWV?
The AMC1200BDWVR and AMC1200BDWV are functionally identical isolated amplifiers from Texas Instruments; the only difference is the packaging format. The AMC1200BDWVR is supplied in tape-and-reel packaging (suffix "R") for automated high-volume assembly, while the AMC1200BDWV is supplied in tube/rail packaging for lower-volume or prototype use. Both share the same die, electrical specifications, and SOIC-8 (DWV) package outline.
Are the AMC1200BDWVR and AMC1200BDWV electrically and functionally interchangeable?
Yes. Both devices are the same isolated amplifier with identical key specifications, including a ±250 mV input voltage range, fixed gain of 8, a 4.25 kV peak isolation rating (per UL 1577), and a 5 V supply on both the input and output sides. Because the silicon and package outline are the same, they are interchangeable in a given design; only the delivery format differs.
What package do the AMC1200BDWVR and AMC1200BDWV use?
Both parts are offered in the DWV package, an 8-pin SOIC (wide-body) package. The "DWV" suffix in both part numbers denotes this package. The package outline, pinout, and PCB land pattern are identical between the two orderable variants.
What is the isolation rating of the AMC1200BDWVR and AMC1200BDWV?
Both devices are rated for 4.25 kV peak isolation per UL 1577 and are designed for reinforced isolation applications. They also carry a working voltage specification suitable for isolated current-sensing and voltage-sensing in motor drive and industrial systems. Designers should confirm the applicable isolation standard and working-voltage rating in the official TI datasheet for their end application.
What are the key electrical specifications shared by the AMC1200BDWVR and AMC1200BDWV?
Both parts feature a ±250 mV linear input range, a fixed gain of 8, a 5 V nominal supply on both sides, and a differential output. They are intended for shunt-based current sensing in isolated industrial and motor-control applications. For complete min/max limits, offset, gain error, and nonlinearity specifications, refer to the Texas Instruments AMC1200 datasheet.
Which variant should I choose for high-volume automated assembly?
For high-volume production using automated pick-and-place equipment, the AMC1200BDWVR (tape-and-reel) is the appropriate choice. The AMC1200BDWV (tube/rail) is typically used for prototyping, low-volume runs, or manual assembly where reel packaging is not required.
Do the AMC1200BDWVR and AMC1200BDWV differ in temperature range or qualification?
No. Both orderable variants are based on the same device and share the same operating temperature range and qualification status as specified by Texas Instruments. Packaging format does not affect the temperature grade or reliability qualification of the part.
