Replacement verdict
Compatible functional replacement candidate
The AMC1306M25DWVR and AMC1350DWVR are both isolated delta-sigma modulators in the same SOIC-8 (DWV) package and share a compatible supply architecture, making the AMC1350DWVR a viable functional replacement candidate for the AMC1306M25DWVR in isolated shunt-based current sensing designs. However, the two devices differ in input voltage range, output bitstream format, and isolation rating, so the replacement must be validated against the system's signal-chain and safety requirements before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | AMC1306M25DWVR | AMC1350DWVR | Why it matters |
|---|---|---|---|
| Input Type | Current (shunt-based, differential) | Voltage (resistive divider, differential) | Determines the physical quantity being sensed; a current-sense device cannot directly replace a voltage-sense device without redesigning the sensing front end. |
| Input Voltage Range | ±250 mV | ±5 V | Defines the maximum signal the device can accept; the 20x difference means the two parts are not interchangeable for the same signal amplitude. |
| Isolation Voltage (VISO) | 5000 V RMS (reinforced) | 5000 V RMS (reinforced) | Both provide reinforced isolation, so safety ratings are equivalent, but this alone does not make them functionally substitutable. |
| Output Interface | Delta-sigma bitstream (1-bit) | Differential analog output | The output format dictates the downstream signal chain; a bitstream requires a digital filter/SINC stage, while an analog output feeds an ADC directly. |
| Gain / Sensitivity | 8.2 mV/V (fixed gain) | 0.4 V/V (fixed gain) | The transfer function must match the sensor and ADC scaling; mismatched gain changes the effective measurement range and resolution. |
| Supply Voltage | 3.0 V to 5.5 V (high side), 3.0 V to 5.5 V (low side) | 3.0 V to 5.5 V (high side), 3.0 V to 5.5 V (low side) | Both operate over the same supply window, so power-rail compatibility is not a differentiator between these parts. |
| Package | 8-pin SOIC (DWV) | 8-pin SOIC (DWV) | Identical footprint allows drop-in PCB placement, but electrical differences still prevent direct substitution. |
| Operating Temperature Range | -40°C to +125°C | -40°C to +125°C | Matching temperature ratings means both suit the same harsh environments, but this does not address functional differences. |
| Typical Application | Motor drive shunt current sensing, inverter phase current | Isolated voltage sensing, DC-link and grid voltage monitoring | The intended use cases differ fundamentally; selecting the wrong type leads to incorrect measurement topology and potential safety or accuracy failures. |

Frequently asked questions
What are the primary functional differences between the AMC1306M25DWVR and the AMC1350DWVR?
The AMC1306M25DWVR is a precision isolated delta-sigma modulator with a ±250 mV input range, designed for shunt-based current sensing. The AMC1350DWVR is an isolated amplifier with a ±250 mV input range and a differential output, designed for voltage and current sensing applications. The AMC1306M25DWVR outputs a 1-bit delta-sigma bitstream, while the AMC1350DWVR provides an analog differential output.
Are the AMC1306M25DWVR and AMC1350DWVR pin-to-pin compatible?
Both devices are offered in the same 8-pin SOIC (DWV) package, but they are not functionally interchangeable. The AMC1306M25DWVR provides a digital bitstream output on its data pins, whereas the AMC1350DWVR provides an analog differential output. Pin functions and the required external signal chain differ, so direct substitution without design validation is not supported.
What is the input voltage range for each device?
Both the AMC1306M25DWVR and the AMC1350DWVR specify a linear input range of ±250 mV, making them suitable for low-side shunt current sensing where the shunt voltage is small. Designs requiring a different input range should select the appropriate variant from the respective families.
What output format does each device provide?
The AMC1306M25DWVR provides a 1-bit delta-sigma modulated digital output that must be processed by a digital filter or modulator interface. The AMC1350DWVR provides a differential analog output voltage that can be fed directly to an ADC or analog signal chain.
What are the isolation ratings of these devices?
Both devices are reinforced isolated devices. The AMC1306M25DWVR is rated for a maximum working isolation voltage of 1500 V RMS per its datasheet, and the AMC1350DWVR is rated for a maximum working isolation voltage of 1500 V RMS. Both are specified for a maximum transient isolation voltage of 7071 V peak. Designers should confirm the exact isolation specifications against the latest manufacturer datasheet for the target application.
Which device should be selected for a design that requires a digital output to an MCU?
The AMC1306M25DWVR is the appropriate choice when a digital delta-sigma bitstream is required, as it interfaces directly with MCU or DSP modulator inputs. The AMC1350DWVR, with its analog differential output, is better suited to designs that use an external ADC or analog signal conditioning path.
Do both devices support the same supply voltage configuration?
Both devices use a two-supply architecture with a high-side supply and a low-side supply. The AMC1306M25DWVR operates with a high-side supply of 3.0 V to 5.5 V and a low-side supply of 2.7 V to 5.5 V. The AMC1350DWVR operates with a high-side supply of 3.0 V to 5.5 V and a low-side supply of 3.0 V to 5.5 V. Designers should verify the exact supply ranges in the respective datasheets before finalizing the power design.
