GENERAL INFORMATION
MC33502 dual operational amplifier unique ability provide rail-to-rail performance both input output using SMARTMOS process. amplifier output swings within both rails able provide output drive current with supply, with supply. bandwidth slew rate V/µs achieved with high speed depletion mode NMOS (DNMOS) vertical transistors. This device characterized over temperature range -40°C 105°C.
minimize input offset voltage. common mode feedback path also employed enable offset voltage track over input common mode voltage. total operational amplifier quiescent current drop mA/amp. Output Stage additional feature this device demand" base current cancellation amplifier. This feature provides base drive output power devices making buffer amplifier perform voltage-to-current conversion. This done direct proportion load conditions. buffer necessary isolate load current effects output stage from input stage. Because voltage conditions, DNMOS follower used provide essentially zero voltage level shift. This buffer isolates load current changes output stage from loading input stage. This demand" feature allows these amplifiers consume only micro-amps current when output stage quiescent mode. provides high output current when required load. rail-to-rail output stage current boost circuit provides output current with supply (For supply output stage will enabling operational amplifier drive load. high speed vertical transistor provides excellent frequency performance while sourcing current. operational amplifier also internally compensated provide phase margin degrees. unity gain with supply with supply.
CIRCUIT INFORMATION
Input Stage volt rail-to-rail performance achieved MC33502 input using single pair depletion mode NMOS devices (DNMOS) form differential amplifier with very input current normal input common mode range DNMOS device, with implanted negative threshold, includes ground relies body effect dynamically shift threshold positive value gates moved from ground towards positive supply. Because device manufactured p-well process, body effect coefficient sufficiently large ensure that input stage will remain saturated when inputs positive rail. This also applies very supply voltages. rail-to-rail input stage consists DNMOS differential amplifier, folded cascode, voltage balanced mirror. voltage cascoded balanced mirror provides high stage gain base current cancellation without sacrificing signal integrity. Also, input offset voltage trimmed less than because limited available supply voltage. body voltage input DNMOS differential pair internally trimmed
VOLTAGE OPERATION
MC33502 will operate supply voltages from ground. Since device rail-to-rail both input output, high dynamic range single battery cell applications possible.
