Description

The AMC1306M25E is a precision, delta-sigma (ΔΣ) modulator with the output separated from the input circuitry by an isolation barrier that is highly resistant to magnetic interference. This barrier is certified to provide reinforced isolation of up to 7070 VPEAKaccording to the DIN EN IEC 60747-17 (VDE 0884-17) and UL1577 standards, and supports a working voltage up to 1.5 kVRMS. The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from voltages that can cause electrical damage or be harmful to an operator. The input of the AMC1306M25E is optimized for direct connection to shunt resistors or other low voltage-level signal sources. The excellent DC accuracy and low temperature drift supports accurate current control in onboard chargers (OBC), DC/DC converters, traction inverters, or other high-voltage applications. By using an integrated digital filter (such as those in theTMS320F2807xorTMS320F2837xmicrocontroller families) to decimate the bitstream, the device can achieve 16 bits of resolution with a dynamic range of 85 dB at a data rate of 78 kSPS. The AMC1306M25E is offered in a 8-pin, wide-body SOIC package, is fully specified over the extended industrial temperature range of –40°C to +125°C, and supports operation down to –55°C.
