Description

The HA-5135/883 is a precision operational amplifier manufactured using a combination of key technological advancements to provide outstanding input characteristics. A high Beta input stage is combined with laser trimming, dielectric isolation, and matching techniques to produce 75µV (max) input offset voltage and 0.4µV/oC (max) input offset voltage average drift. Other features enhanced by this process include 9nV/√Hz (typ) Input Noise Voltage, 4nA Input Bias Current (max) and 120dB Open Loop Gain (min).

These features coupled with 106dB CMRR and 94dB PSRR make HA-5135/883 an ideal device for precision D.C. instrumentation amplifiers. Excellent input characteristics in conjunction with 0.6MHz (min) bandwidth and 0.5V/µs (min) slew rate, makes this amplifier extremely useful for precision integrator and biomedical amplifier designs. These amplifiers are also well suited for precision data acquisition and for accurate threshold detector applications.
