NSi1306 High Reliability Reinforced Isolated Sigma-Delta Modulator Datasheet (EN) 1.6 Product Overview  Operation Temperature: -40℃~125℃ 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.  RoHS-Compliant Packages: Key Features Device Information  Clock frequency: 5MHz to 21MHz  ±50mV or ±250mV Linear Input Voltage Range  Excellent DC Performance: ◼ Offset Error: ±50μV or ±100μV (Max) ◼ Offset Drift: -0.5~1.5μV/℃ (Max) ◼ Gain Error: ±0.2% (Max) ◼ Gain Drift: ±40ppm/℃ (Max)  SNR: 82.5dB or 86dB (Typ)  High CMTI: 150kV/μs (Typ)  System-Level Diagnostic Features: ◼ AVDD monitoring ◼ Input common-mode overvoltage detection Copyright © 2020, NOVOSENSE SOP8(300mil) ◼ SOP16(300mil) Safety Regulatory Approvals  UL recognition: up to 5000Vrms for 1 minute per UL1577  CQC certification per GB4943.1-2011  CSA component notice 5A approval IEC60950-1 standard  DIN VDE V 0884-11:2017-01 Applications  Shunt current monitoring  AC motor controls  Power and solar inverters  Uninterruptible Power Suppliers  Automotive onboard chargers Part Number NSI1306x-DSWVR Package SOP8(300mil) Body Size 5.85mm × 7.50mm NSI1306x-DSWR SOP16(300mil) 10.30mm × 7.50mm Functional Block Diagrams AVDD DVDD VDD1 detection Reference INP Σ-Δ modulator TX INN Isolation Barrier  Up to 5000VRMS Insulation Voltage ◼ RX VCM detection AGND RX DOUT TX CLKIN DGND Figure 1.
