AMC1301DWV

Overview

The AMC1301DWV is a precision reinforced isolated amplifier manufactured by Texas Instruments, housed in an SOIC-8 surface-mount package. It features a single channel with a fixed gain of 8.2 V/V and supports a ±250-mV input range. The device provides galvanic isolation rated at 5 kVrms and delivers a differential output capable of sourcing up to 13 mA per channel. Key electrical specifications include a 3-dB bandwidth of 210 kHz, a gain-bandwidth product of 1 MHz, and a common-mode rejection ratio (CMRR) of 93 dB. Input characteristics specify a bias voltage of 50 µV and a bias current of -60 µA, with a gain error of 0.03%. Power requirements are met by a supply voltage range of 3 V to 5.5 V, drawing 5 mA of operating current. The component operates within a temperature range of -40°C to +125°C.

Feature Summary

• Provides reinforced galvanic isolation for high-voltage safety and noise immunity
• Delivers fully differential output signals for robust signal integrity
• Maintains high precision with low offset voltage and minimal gain error

Applications

• Current sensing in motor drive systems
• Energy metering applications requiring precise measurement
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix 'DWV' indicates tube packaging rather than reel or cut tape formats when reviewing distributor listings. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure design compatibility with the specified SOIC-8 footprint and thermal dissipation requirements for the target operating environment.

Selection Notes

Select this component when a fixed gain of 8.2 V/V matches the sensor interface requirements. The 210 kHz bandwidth suits applications where moderate speed is sufficient without the complexity of modulator-based architectures. Consider the 5 kVrms isolation rating against system voltage stress levels and ensure the ±250-mV input window aligns with the transducer output capabilities.

Part Context

This part belongs to the AMC1301 series of precision isolated amplifiers from Texas Instruments. It serves as a standalone solution for isolating analog signals in noisy environments. Unlike delta-sigma modulators that require external digital filtering, this device provides an immediate amplified analog output, simplifying the signal chain design for direct connection to ADCs or other analog processing stages.

Replacement Considerations

AMC1301DWVR shares identical electrical specifications but differs in packaging format.
