The OPA277 series precision op amps replace the industrystandard OP-177. They offer improved noise, wider outputvoltage swing, and are twice as fast with half the quiescentcurrent. Features include ultra low offset voltage and drift, lowbias current, high common-mode rejecTIon, and high powersupply rejecTIon. Single, dual, and quad versions have idenTIcalspecificaTIons for maximum design flexibility.OPA277 series op amps operate from ±2V to ±18V supplieswith excellent performance. Unlike most op amps whichare specified at only one supply voltage, the OPA277 seriesis specified for real-world applications; a single limit appliesover the ±5V to ±15V supply range. High performanceis maintained as the amplifiers swing to their specified limits.Because the initial offset voltage (±20mV max) is so low, useradjustment is usually not required. However, the single version(OPA277) provides external trim pins for special applications.OPA277 op amps are easy to use and free from phase inversionand overload problems found in some other op amps. They arestable in unity gain and provide excellent dynamic behaviorover a wide range of load conditions. Dual and quad versionsfeature completely independent circuitry for lowest crosstalkand freedom from interaction, even when overdriven or overloaded.
