40MHz, PRAM Four Channel Programmable Amplifiers
The HA-2404 comprise a series of four-channel programmable Amplifiers providing a level of versatility unsurpassed by any other monolithic Operational Amplifier Versatility is achieved by employing four input Amplifier channels, any one (or none) of which may be electronically selected and connected to a single output stage through DTL/TTL compatible address inputs. The device formed by the output and the selected pair of inputs is an op amp which delivers excellent slew rate, gain bandwidth and power bandwidth performance. Other advantageous features for these dielectrically isolated Amplifiers include high voltage gain and input impedance coupled with low input offset voltage and offset current. External compensation is not required on this device at closed loop gains greater than 10.
Each channel of the HA-2404 CAN be controlled and operated with suitable feedback networks in any of the standard op amp configurations. This specialization makes these Amplifiers excellent components for multiplexing signal selection and mathematical function designs. With 30V/s slew rate, 40MHz gain bandwidth and 30M input impedance these devices are ideal building blocks for signal generators, active Filters and data acquisition designs. Programmability, coupled with 4mV typical offset voltage and 5nA offset current, makes these Amplifiers outstanding components for Signal Conditioning circuits.
