Product Overview The NSI1306 is a high performance Σ-Δ modulator with output separated from input based on the NOVOSENSE capacitive isolation technology. The device has a linear differential input signal range of ±50mV (±64mV full-scale) or ±250mV (±320mV full-scale). The differential input is ideally suited to shunt resistor-based current sensing in high voltage applications where isolation is required. The analog input is amplified and continuously sampled by a second-order Σ-Δ modulator and converted to a high speed, single bit data stream. The output data is synchronous to the external clock with a frequency range from 5MHz to 21MHz. By using an appropriate digital filter (such as sinc3 filter) to decimate the bitstream, the device can achieve 16 bits resolution and an 86dB/82.5dB signal to noise ratio (SNR) at 78.125kSPS with a 20MHz master clock. The fail-safe functions including input common-mode overvoltage detection and missing AVDD detection simplify system-level design and diagnostics.
