LT1126/LT1127 Dual/Quad Decompensated Low Noise, High Speed Precision Op Amps FEATURES DESCRIPTIO 100% Tested Low Voltage Noise: 2.7nV/Hz Typ, The LT 1126 dual and LT1127 quad are high perfor- 4.2nV/Hz Max mance, decompensated op amps that offer higher slew Slew Rate: 11V/s Typ rate and bandwidth than the LT1124 dual and the LT1125 Gain-Bandwidth Product: 65MHz Typ quad operational amplifiers. The enhanced AC perfor- Offset Voltage, Prime Grade: 70V Max mance is available without degrading DC specs of the Low Grade: 100V Max LT1124/LT1125. Both LT1126/LT1127 are stable in a gain High Voltage Gain: 5 Million Min of 10 or more. Supply Current Per Amplifier: 3.1mA Max In the design, processing and testing of the device, par- Common Mode Rejection: 112dB Min ticular attention has been paid to the optimization of the Power Supply Rejection: 116dB Min entire distribution of several key parameters. Slew rate, Available in 8-Lead SOIC, 8-Lead DIP, 16-Lead SO gain-bandwidth and 1kHz noise are 100% tested for each and 14-Lead DIP Packages individual amplifier. Consequently, the specifications of U even the lowest cost grades (the LT1126C and the LT1127C) APPLICATIO S have been enhanced. Two and Three Op Amp Instrumentation Amplifiers Power consumption of the dual LT1126 is less than one Low Noise Signal Processing half of two OP-37s. Low power and high performance in an Active Filters 8-pin SO package makes the LT1126 a first choice for Microvolt Accuracy Threshold Detection surface mounted systems and where board space is Strain Gauge Amplifiers restricted.
