The CA-IS1305/CA-IS1306 family of devices is series of precision isolated sigma-delta (Σ-Δ) modulator and optimized for shunt resistor-based current sensing or other small signal measurement applications. The analog input-side (high-side) and digital output-side (low-side) are separated by unique silicon oxide (SiO2) capacitive isolation barriers that provide up to 5kVRMS galvanic isolation. In systems with different voltage domains, this isolation technical is typically used to protect the low voltage side from the high voltage side in case of any faults. These devices also feature up to 150kV/μs common mode transient immunity(CMTI) and enable efficient bit-stream transmission in noisy environments.
The CA-IS1305/CA-IS1306 devices specified for operation with 5MHz to 21MHz clock input. The internal sigma-delta modulator combined with an external digital decimation sinc3 filter within FPGA or DSP, can achieve up to 85 dB signal-to-noise ratio (SNR) at 78.1 Ksps.
