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/μs
slew rate, 40MHz gain bandwidth and 30MΩ 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.
During Disable Mode VOUT goes to V-. For high output
impedance during Disable, see HA2444.
