  • Product details

    AD7403is a high performance second-order sigma-delta modulator with on-chip digital isolation using Analog Devices, InciCoupler® technology converts analog input signals into high-speed single-bit data streams. The AD7403 operates in 5 V (VDD1) power supply operation to input ± 250 mV differential signal (320 mV full-scale±). This differential input signal is ideal for monitoring shunt voltages in high voltage applications requiring galvanic isolation.

    The analog input is continuously sampled by a high-performance analog modulator and converted to a digital output stream with a data rate of up to 20 MHz and a density of 1. The original information can be reconstructed with appropriate digital filters to achieve a signal-to-noise ratio (SNR) of 88 dB at 78.1 kSPS. The serial input/output can operate from a 5 V or 3 V supply (VDD2)。

    The serial interface is digitally isolated. By combining high-speed complementary metal-oxide semiconductor (CMOS) technology with monolithic transformer technology, on-chip isolation provides superior operating characteristics compared to other components such as traditional optocouplers. The AD7403 is available in a 16-lead wide-body SOIC package and operates over the −40°C to +125°C temperature range. The AD7403-8 is available in an 8-lead wide-body SOIC package and operates over the −40°C to +105°C temperature range.
