Product Details
The ADuM7701 is a high performance, second-order, Σ-Δ modulator that converts an analog input signal into a high speed, single-bit data stream, with on-chip digital isolation based on Analog Devices, Inc., iCoupler technology. The devices operate from a 5 V (VDD1) power supply and accept a pseudo-differential input signal of ±250 mV (±320 mV full scale). The pseudo-differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required.
The analog input is continuously sampled by a high performance analog modulator, and converted to a ones density digital output stream with a data rate of up to 21 MHz. The original information can be reconstructed with an appropriate digital filter to achieve 86 dB signal to noise ratio (SNR) at 78. l kSPS with a 20 MHz MCLK for the ADuM7701. The serial input/output operates from a 5 V or a 3.3 V supply (VDD2).
The serial interface is digitally isolated. High speed complementary metal oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, means the on-chip isolation provides outstanding performance characteristics, superior to alternatives such as optocoupler devices. The ADuM7701 device is offered in both 16-lead and 8-lead wide-body SOIC packages and have an operating temperature range of -40°C to +125° C.
Applications
- Shunt curent monitoring
- AC motor controls
- Power and solar inverters
- Wind turbine inverters
- Analog-to-digital and optoisolator replacement
