HIFI Electronic Components.
 
Using the multimeter test of true and false:
FEATURES
l VERY LOW NOISE: 4.5nV/√Hz at 10kHz
l FAST SETTLING TIME:
OPA627550ns to 0.01%
OPA637450ns to 0.01%
l LOW VOS: 100V max
l LOW DRIFT: 0.8V/C max
l LOW IB: 5pA max
l OPA627: Unity-Gain Stable
l OPA637: Stable in Gain ≥ 5
APPLICATIONS
l PRECISION INSTRUMENTATION
l FAST DATA ACQUISITION
l DAC OUTPUT AMPLIFIER
l OPTOELECTRONICS
l SONAR, ULTRASOUND
l HIGH-IMPEDANCE SENSOR AMPS
l HIGH-PERFORMANCE AUDIO CIRCUITRY
l ACTIVE FILTERS
DESCRIPTION
The OPA627 and OPA637 Difet operational amplifiers provide a new level of performance in a precision
FET op amp. When compared to the popular OPA111
op amp, the OPA627/637 has lower noise, lower offset
voltage, and much higher speed. It is useful in a broad
range of precision and high speed analog circuitry.
The OPA627/637 is fabricated on a high-speed, dielectrically-isolated complementary NPN/PNP process. It
operates over a wide range of power supply voltage
4.5V to 18V. Laser-trimmed Difet input circuitry
provides high accuracy and low-noise performance
comparable with the best bipolar-input op amps.
High frequency complementary transistors allow increased circuit bandwidth, attaining dynamic performance not possible with previous precision FET op
amps. The OPA627 is unity-gain stable. The OPA637
is stable in gains equal to or greater than five.
Difet fabrication achieves extremely low input bias
currents without compromising input voltage noise
performance. Low input bias current is maintained
over a wide input common-mode voltage range with
unique cascode circuitry.
The OPA627/637 is available in plastic DIP, SOIC
and metal TO-99 packages. Industrial and military
temperature range models are available.


All the goods 100% by test,and if buy it from the forums can have a discount .
