AMC1300BDWV

Overview

The AMC1300BDWV is a precision, reinforced isolated amplifier from Texas Instruments featuring a ±250-mV input range. It provides galvanic isolation with an insulation voltage of 5000 Vrms and a 3dB bandwidth of 310 kHz. The device offers a fixed gain of 8.2 V/V with a low gain error of 0.03%. Key electrical specifications include a common-mode rejection ratio (CMRR) of 100 dB, an input bias current of -24 uA, and an input offset voltage of 200 uV. It operates on a single supply voltage between 3 V and 5.5 V, drawing 6.3 mA of quiescent current. The component supports an extended operating temperature range from -55°C to +125°C and is housed in an SOIC-8 package.

Procurement Notes

Verify the specific suffix 'BDWV' against the official Texas Instruments datasheet to confirm the exact temperature grade and packaging configuration. Ensure the procurement channel provides valid traceability documentation. Confirm that the component meets RoHS compliance requirements as specified in the manufacturer's product information before finalizing orders.

Selection Notes

Select this component when a high level of precision is required alongside robust isolation capabilities. The ±250-mV input range makes it suitable for shunt-based current sensing applications. Consider the 310 kHz bandwidth and low offset voltage for dynamic signal processing needs. Verify that the system power supply constraints align with the 3 V to 5.5 V operating range.

Part Context

This part belongs to the AMC1300 series of isolated amplifiers designed for demanding industrial environments. It utilizes capacitive isolation technology to separate high-voltage sides from low-voltage control circuitry. The series is engineered to provide reliable performance in noisy electrical environments where signal integrity is critical.

Replacement Considerations
