ADS774JE

The ADS774JE is a 12-bit successive approximation analog-to-digital converter using an innovative capacitor array (CDAC) implemented in low-power CMOS technology.The ADS774JE is complete with internal clock,microprocessor interface, three-state outputs, and internal scaling resistors for input ranges of 0V to +10V, 0V to +20V,±5V,or ±10V.

The absolute maximum ratings of the ADS774JE can be summarized as:(1):the parameter is VEE to digital common,the rating is +VDD to 16.5,the unit is V;(2):the parameter is VDD to digital common,the rating is 0 to +7,the unit is V;(3):the parameter is analog common to digital common,the rating is ±1,the unit is V;(4):the parameter is control inputs (CE, CS, AO, 12/8, R/C) to digital common,the rating is -0.5 to VDD+0.5,the unit is V;(5):the parameter is analog inputs (ref in,bipolar offset,10VIN ) to analog common,the rating is ±16.5,the unit is V;(6):the parameter is 20VIN to analog common,the rating is ±24,the unit is V;(7):the parameter is ref out,the rating is indefinite short to common,momentary short to VDD;(8):the parameter is Max junction temperature,the rating is +165,the unit is ;(9):the parameter is power dissipation,the rating is 1000,the unit is mW;(10):the parameter is lead temperature (soldering,10s),the rating is +300,the unit is ;(11):the parameter is thermal resistance,JA : plastic DIPs,the rating is 100,the unit is /W;(12):the parameter is thermal resistance,JA : SOIC,the rating is 100,the unit is /W.
