CS5460A-BS

The CS5460A-BS is designed as a highly integrated analog to digital converter (ADC) which combines two ADCs, high speed power calculation functions and a serial interface on a single chip.

CS5460A-BS has many features. (1)Energy data linearity 0.1% reading over 1000:1 dynamic range. (2)On-chip functions: energy, I*V, Irms and Vrms, energy to pulse-rate conversion. (3)Smart auto-boot mode from serial EEPROM with no microcontroller. (4)AC to DC system calibration. (5)Mechanical counter/stepper motor driver. (6)Meets accuracy spec for IEC 687/1036, JIS. (7)Power consumption <12mW. (8)Interface optimized for shunt sensor. (9)Phase compensation. (10)Ground-referenced signals with single supply. (11)On-chip 2.5V reference (max 60ppm/°C drift). (12)Simple three-wire serial interface. (13)Watch dog timer. And so on.

Some absolute maximum ratings of CS5460A-BS have been concluded into several points as follow. (1)Its DC power supplies would be min -0.3V and max +6.0V for positive digital and would be min -0.3V and max +6.0V for positive analog and would be min +0.3V and max -6.0V for negative analog. (2)Its input current any pin except supplies would be max =/-10mA. (3)Its output current would be max +/-25mA. (4)Its power dissipation would be 500mW. (5)Its analog input voltage would be min -0.3V and max (VA+)+0.3V. (6)Its digital input voltage would be min -0.3V and max (VD+)+0.3V. (7)Its ambient operating temperature range would be from -40°C to 85°C. (8)Its storage temperature range would be from -65°C to 150°C.

Also some analog electrical characteristics of CS5460A-BS are concluded as follow. (1)Its total harmonic distortion would be min 74dB. (2)Its common mode rejection would be min 80dB. (3)Its offset drift (without the high pass filter) would be typ 5nV/°C. (4)Its input capacitance would be typ 0.2pF. (5)Its crosstalk with current channel at full scale would be max -70dB. (6)Its common mode+signal on VIN+ or VIN- would be min -0.25V and max VA+. And so on. If you have any question or suggestion please contact us. Thank you!
