General Purpose Amplifier 4 Circuit 14-PDIP
The OPA4227PA is a quad Operational Amplifier combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both AC and precision DC performance. The OPAx227 is unity-gain stable and features high slew rate (2.3V/µs) and wide bandwidth (8MHz). The OPAx227 series operational amplifier is pin-for-pin replacements for the industry standard OP-27 and OP-37 with substantial improvements across the board.
The OP470GPZ is a high-performance monolithic quad Operational Amplifier features exceptionally low voltage noise, offering comparable performance to PMI"s industry standard OP27. The OP470 features an input offset voltage below 0.4mV, excellent for a quad op-amp and an offset drift under 2µV/°C, guaranteed over the full military temperature range. Input bias is under 25nA which reduces errors due to signal source resistance. The OP470"s CMR of over 110dB and PSRR of less than 1.8µV/V significantly reduce errors due to ground noise and power supply fluctuations. Power consumption of the quad OP470 is half that of four OP27s, a significant advantage for power conscious applications. The OP470 is unity-gain stable with a gain-bandwidth product of 6MHz and a slew rate of 2V/µs.
