Texas Instruments AMC1305M25DWR

Description
The AMC1305 is a high-precision, reinforced isolated delta-sigma modulator with a capacitive double isolation barrier that provides reinforced isolation of up to 7000 VPEAK. It is optimized for direct connection to shunt resistors or other low voltage level signal sources, supporting excellent dc and ac performance. The device is available in a wide-body SOIC-16 (DW) package and is specified from -40°C to 125°C.
