Itsvery low offset voltage and offset voltage drift are the results ofadvanced laser wafer trimming technology. These performancebenefits allow the user to easily upgrade existing designs that useolder precision BiFETs and, in many cases, bipolar op amps.The superior ac and dc performance of this op amp makes itsuitable for active filter applications. With a slew rate of 16 V/µsand a settling time of 1 µs to ±0.01%, the AD711 is ideal as abuffer for 12-bit D/A and A/D Converters and as a high-speedintegrator. The settling time is unmatched by any similar ICamplifier.The combination of excellent noise performance and low inputcurrent also make the AD711 useful for photo diode preamps.Common-mode rejection of 88 dB and open loop gain of400 V/mV ensure 12-bit performance even in high-speed unitygain buffer circuits.The AD711 is pinned out in a standard op amp configurationand is available in seven performance grades. The AD711J andAD711K are rated over the commercial temperature range of0°C to +70°C. The AD711A, AD711B and AD711C are ratedover the industrial temperature range of –40°C to +85°C. TheAD711S and AD711T are rated over the military temperaturerange of –40°C to +125°C and are available processed to MIL-STD-883B, Rev. C.Extended reliability PLUS screening is available, specified overthe commercial and industrial temperature ranges. PLUSscreening includes 168-hour burn-in, as well as other environ-mental and physical tests.The AD711 is available in an 8-pin plastic mini-DIP, small out-line, cerdip, TO-99 metal can, or in chip form.PRODUCT HIGHLIGHTS1. The AD711 offers excellent overall performance at verycompetitive prices.2. Analog Devices’ advanced processing technology and with100% testing guarantees a low input offset voltage (0.25 mVmax, C grade, 2 mV max, J grade). Input offset voltage isspecified in the warmed-up condition. Analog Devices’ laserwafer drift trimming process reduces input offset voltagedrifts to 3 µV/°C max on the AD711C.3. Along with precision dc performance, the AD711 offersexcellent dynamic response. It settles to ±0.01% in 1 µs andhas a 100% tested minimum slew rate of 16 V/µs. Thus thisdevice is ideal for applications such as DAC and ADCbuffers which require a combination of superior ac and dcperformance.4. The AD711 has a guaranteed and tested maximum voltagenoise of 4 µV p-p, 0.1 to 10 Hz (AD711C).5. Analog Devices’ well-matched, ion-implanted JFETs ensurea guaranteed input bias current (at either input) of 25 pAmax (AD711C) and an input offset current of 10 pA max(AD711C). Both input bias current and input offset currentare guaranteed in the warmed-up condition.CONNECTION DIAGRAMSTO-99 Plastic Mini-DIP (N) Package(H) Package Plastic Small Outline (R)andCerdip (Q) PackageJ/A/S K/B/T CParameter Min Typ Max Min Typ Max Min Typ Max UnitsINPUT OFFSET VOLTAGE1Initial Offset 0.3 2/1/1 0.2 0.5 0.10 0.25 mVTMIN to TMAX3/2/2 1.0 0.45 mVvs. Temp 7 20/20/20 5 10 2 5 µV/°Cvs. Supply 76 95 80 100 86 110 dBTMIN to TMAX76/76/76 80 86 dBLong-Term Stability 15 15 15 µV/MonthINPUT BIAS CURRENT2VCM = 0 V 15 50 15 50 15 25 pAVCM = 0 V @ TMAX1.1/3.2/51 1.1/3.2/51 1.6 nAVCM = ±10 V 20 100 20 100 20 50 pAINPUT OFFSET CURRENTVCM = 0 V 10 25 5 25 5 10 pAVCM = 0 V @ TMAX0.6/1.6/26 0.6/1.6/26 0.65 nAFREQUENCY RESPONSESmall Signal Bandwidth 3.0 4.0 3.4 4.0 3.4 4.0 MHzFull Power Response 200 200 200 kHzSlew Rate 16 20 18 20 18 20 V/µsSettling Time to 0.01% 1.0 1.2 1.0 1.2 1.0 1.2 µsTotal Harmonic Distortion 0.0003 0.0003 0.0003 %INPUT IMPEDANCEDifferential 3 × 1012i5.5 3 × 1012i5.5 3 × 1012i5.5 ΩipFCommon Mode 3 × 1012i5.5 3 × 1012i5.5 3 × 1012i5.5 ΩipFINPUT VOLTAGE RANGEDifferential3±20 ±20 ±20 VCommon-Mode Voltage4+14.5, –11.5 +14.5, –11.5 +14.5, –11.5TMIN to TMAX–VS + 4 +VS – 2 –VS + 4 +VS – 2 –VS + 4 +VS – 2 VCommon-ModeRejection RatioVCM = ±10 V 76 88 80 88 86 94 dBTMIN to TMAX76/76/76 84 80 84 86 90 dBVCM = ±11 V 70 84 76 84 76 90 dBTMIN to TMAX70/70/70 80 74 80 74 84 dBINPUT VOLTAGE NOISE 2 2 2 4 µV p-p45 45 45 nV/√Hz22 22 22 nV/√Hz18 18 18 nV/√Hz16 16 16 nV/√HzINPUT CURRENT NOISE 0.01 0.01 0.01 pA/√HzOPEN-LOOP GAIN 150 400 200 400 200 400 V/mV100/100/100 100 100 V/mVOUTPUT CHARACTERISTICSVoltage +13, –12.5 +13.9, –13.3 +13, –12.5 +13.9, –13.3 +13, –12.5 +13.9, –13.3 V±12/±12/612 +13.8, –13.1 612 +13.8, –13.1 612 +13.8, –13.1 VCurrent 25 25 25 mAPOWER SUPPLYRated Performance ±15 ±15 ±15 VOperating Range 64.5 618 64.5 618 64.5 618 VQuiescent Current 2.5 3.4 2.5 3.0 2.5 2.8 mANOTES1Input Offset Voltage specifications are guaranteed after 5 minutes of operation at TA = +25°C.2Bias Current specifications are guaranteed maximum at either input after 5 minutes of operation at TA = +25°C.
