LD120

The LD120 is designed as one kind of 1/2 digit A/D converter system for use in display and microprocessor based data acquisition applications. Based on Siliconix's "Quantized Feedback" technique, intrinsic features include auto-polarity, auto-zero, and ratiometric operation. This device can be used in (1)high accuracy digital voltmeters and panel meters;(2)digital scales and thermometers;(3)uP data acquisition systems;(4)scientific instrumentation.

Features of the LD120 are:(1)0.005% +/-1 count accuracy;(2)+/-200.0 mV and +/-2.000 V ranges;(3)auto-zero;(4)auto-polarity;(5)over and under range outputs. And the benefits of this device are:(1)high system performance;(2)single resistor programming;(3)nulls out offsets;(4)single reference;(5)easily interfaced.

The absolute maximum ratings of the LD120 can be summarized as:(1)VIN:V-<VIN,V+;(2)Iinput:+/-1 mA;(3)V+ - V-:32 V;(4)Vss - VDD:20 V;(5)any pin:VDD to Vss+/-0.3 V;(6)VREF:V+;(7)operating temperature:0 to 70;(8)storage temperature:-65 to +125;(9)power dissipation:750 mW.
