0-400 over the full military temperature range. Open-poof gain of the OP-400 is over 5,000,000 into a 10k{1 load; input bias current is under 3nA; CMA is above 120dB and PURR below On-chip zen er-zap trimming is used to achieve the fow input offset voltage of the OP-400 and eliminates the need for offset bulling. {The OP-400 conforms to the industry-standard gad pin out which does not have null terminals.) The OP-400 features low power consumption, drawing less than 725uA per amplifier.

0-400 BURN-IN CIRCUIT APPLICATIONS INFORMATION The OP-400 is inherently stable at all gains and is capable of driving large capacities loads without oscillating. Nonetheless, good supply decoupling is highly recommended. Proper supply decoupling reduces problems caused by supply line noise and improves the capacities Joan driving capability of the Q-400. Total supply current can be reduced by connecting the inputs of an unused amplifier to V—. This turn the amplifier off, dowering the total supply current.
