FEATURES
DESCRIPTION
OPA827 series JFET operational amplifiers combine outstanding precision with excellent performance. These amplifiers offer offset voltage (150µV, max), very drift over temperature (1.5µV/°C, typ), bias current (15pA, typ), very 0.1Hz 10Hz noise (250nVPP, typ). device operates over wide supply voltage range, ±18V supply current (4.8mA/Ch, typ). Excellent characteristics, such 22MHz gain bandwidth product (GBW), slew rate 28V/µs, precision characteristics make OPA827 series well-suited wide range applications including 16-bit 18-bit mixed signal systems, transimpedance (I/V-conversion) amplifiers, filters, precision ±10V front ends, professional audio applications.

PHASE-REVERSAL PROTECTION
OPA827 family internal phase-reversal protection. Many FET-input amps exhibit phase reversal when input driven beyond linear common-mode range. This condition most often encountered noninverting circuits when input driven beyond specified common-mode voltage range, causing output reverse into opposite rail. input circuitry OPA827 prevents phase reversal with excessive common-mode voltage; instead, output limits into appropriate rail (see Figure 29).

PHASE-LOCK LOOP
OPA827 well-suited phase-lock loop (PLL) applications because voltage offset, noise, wide gain bandwidth. Figure illustrates example OPA827 this application. first amplifier (OPA827) provides loop low-pass, active filter function, while second amplifier (OPA211) serves scaling amplifier. This second stage amplifies error voltage appropriate level before applied voltage-controlled oscillator (VCO). Operational amplifiers used applications often required have voltage offset. with other levels generated loop, voltage offset applied interpreted phase error.
operational amplifier with inherently voltage offset helps reduce this source error. Also, noise produced operational amplifiers modulates voltage applied limits spectral purity oscillator output. generates noise-related, random phase variations own, this characteristic becomes worse when input voltage source noise included.

Pb-Free (RoHS): TI's terms "Lead-Free" "Pb-Free" mean semiconductor products that compatible with current RoHS requirements substances, including requirement that lead exceed 0.1% weight homogeneous materials. Where designed soldered high temperatures, Pb-Free products suitable specified lead-free processes. Pb-Free (RoHS Exempt): This component RoHS exemption either lead-based flip-chip solder bumps used between package, lead-based adhesive used between leadframe. component otherwise considered Pb-Free (RoHS compatible) defined above. Green (RoHS Sb/Br): defines "Green" mean Pb-Free (RoHS compatible), free Bromine (Br) Antimony (Sb) based flame retardants exceed 0.1% weight homogeneous material)
MSL, Peak Temp. Moisture Sensitivity Level rating according JEDEC industry standard classifications, peak solder temperature.
