AMC3336 Precision Isolated Delta-Sigma Modulator
[Partner Content] The fully integrated, isolated DC/DC converter allows single-supply operation from the low-side.
The fully integrated, isolated DC/DC converter allows single-supply operation from the low-side.
Now available at Mouser Electronics, the reinforced capacitive isolation barrier is certified according to VDE V 0884-11 and UL1577 and supports a working voltage of up to 1.2kVRMS. The isolation barrier separates parts of the system that operate on different common-mode voltage levels and protects the low-voltage side from hazardous voltages and damage.
The input of the Texas Instruments AMC3336 is optimized for direct connection to a resistor network or other high-impedance voltage-signal source. The excellent DC accuracy and low temperature drift support accurate voltage measurements over the extended industrial temperature range from –40°C to +125°C. By using a digital filter (such as a sinc3 filter) to decimate the bitstream, the device can achieve 16 bits of resolution with a dynamic range of 85dB at a data rate of 78kSPS.
The main area of applications is isolated voltage sensing in motor drives, photovoltaic inverters, power delivery systems, and protection relays.
