The HA-5127 monolithic operational amplifier features an unparalleled combination of precision DC and wideband High-Speed characteristics. Utilizing the Intersil D. I. technology and advanced processing techniques, this unique design unites low noise (3nV/√Hz) precision instrumentation performance with High-Speed (10V/µs) wideband capability. This amplifier's impressive list of features include low VOS (10µV), wide unity gain-bandwidth (8. 5MHz), high open loop gain (1800V/mV), and high CMRR (126dB). Additionally, this flexible device operates over a wide supply range (±5V to ±15V) while consuming only 140mW of power. Using the HA-5127 allows designers to minimize errors while maximizing speed and bandwidth. This device is ideally suited for low level transducer signal amplifier circuits. Other applications which can utilize the HA-5127's qualities include instrumentation amplifiers, pulse amplifiers, audio preamplifiers, and signal conditioning circuits. This device can easily be used as a design enhancement by directly replacing the 725, OP25, OP06, OP07, OP27 and OP37. For the military grade product, refer to the HA-5127/883 data sheet.
