The input current-sense amplifier monitors current flow through a shunt (sense) resistor and the sigma-delta modulator converts the Copyright © 2020, Chipanalog Incorporated Shanghai Chipanalog Microelectronics Co., Ltd. analog input to a digital bit stream of 1's and 0's at a much higher frequency. 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 per UL1577 certification, and isolator drivers transfer the output of the modulator across this isolation barrier. 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 and enable efficient bit-stream transmission in noisy environments. The CA-IS1306x devices’ ultra-low input voltage range (±250mV) allows the use of small sense resistor to reduce power dissipation and a very low, 0.2% gain error ensures measurement accuracy. The digital output stage provides Manchester coded(CA-IS1306Ex) or uncoded(CA-IS1306Mx) options. The devices with Manchester coded output offer single-wire data and clock transfer without having to consider the setup time and hold time requirements for the receiving device. This family of devices also features fail-safe output to support high safety system design. The CA-IS1306x devices specified for operation with 5MHz to 21MHz clock input. The internal sigma-delta modulator combined with an external digital decimation sinc3 filter can achieve 85 dB signal-to-noise ratio (SNR) at 78.1 Ksps. The CA-IS1306x family is specified over the -40°C to +125°C operating temperature range and is available in 8-pin SOIC wide body package.
