 HM8631, HM8632, HM8634 520μA, 6.5MHz, RRIO CMOS Operational Amplifiers General Description The HM8631 (single), HM8632 (dual) and HM8634 (quad) are low noise, low voltage, and micro power operational amplifiers. With an excellent bandwidth of 6.5MHz, a slew rate of 4.5V/μs, and a quiescent current of 520μA per amplifier at 5V, the HM863x family can be designed into a wide range of applications. The HM863x op-amps are designed to provide optimal performance in low voltage and low noise systems. The input common-mode voltage range includes ground, and the maximum input offset voltage are 4.2mV. These parts provide rail-to-rail output swing into heavy loads. The HM863x family is specified for single or dual power supplies of +2.3V to +5.5V. All models are specified o
