MX7582

The MX7582 is a complete,calibrated 4-channel 12-bit A/D converter which maintains true 12-bit performance over the full operating temperature range without external adjustments.In addition,each 100s conversion includes an auto-zero cycle which reduces zero errors to typically below 100V.CHIP SELECT,READ,and WRITE input are included for easy microprocessor interfacing without additional logical.2-byte,12-bit conversion data is provided over an 8-bit three-state output bus.Either byte may be read first.Two address bits control the 4-channel input multiplexer.The MX7582's analog input range is 0V to +5V when using a +5V reference.All four high-impedance input channels have excellent matching (typically 0.05LSB).

The MX7582 has some absolute maximum ratings.When parameter is VDD to DGND,the rating is -0.3V,+17V.When parameter is VSS to DGND,the rating is +0.3V,-17V.When parameter is AGND to DGND,the rating is -0.3V,REFIN+0.3V.When parameter is VCC to VDD,the rating is -0.3V,VDD+0.3V.When parameter is VCC to DGND,the rating is -0.3V,+7V.When parameter is REFIN to AGND,the rating is -0.3V,VDD+0.3V.When parameter is AIN0-AIN3 to AGND,the rating is -0.3V,VDD+0.3V.When parameter is digital input voltage to DGND,the rating is -0.3V,VDD+0.3V.When parameter is digital output voltage to DGND,the rating is -0.3V,VDD+0.3V.When parameter is power dissipation (any package) to +75,the rating is 1000mW.When parameter is power dissipation (any package) derate above +75 by,the rating is 10W/.When parameter is storage temperature range,the rating is -65 to +150.When parameter is lead temperature (soldering,10sec),the rating is 300.
