LT1124/LT1125 Dual/Quad Low Noise, High Speed Precision Op Amps Fea T Descrip T n 100% Tested Low Voltage Noise: The LT 1124 dual and LT1125 quad are high performance op amps that offer higher gain, slew rate and bandwidth 2.7nV/Hz Typ than the industry standard OP-27 and competing OP-270/ 4.2nV/Hz Max n OP-470 op amps. In addition, the LT1124/LT1125 have Slew Rate: 4.5V/s Typ n lower I and I than the OP-27 lower V and noise Gain-Bandwidth Product: 12.5MHz Typ B OS OS n than the OP-270/OP-470. Offset Voltage, Prime Grade: 70V Max In the design, processing and testing of the device, par- Low Grade: 100V Max ticular attention has been paid to the optimization of the n High Voltage Gain: 5 Million Min entire distribution of several key parameters. Slew rate, n Supply Current Per Amplifier: 2.75mA Max gain bandwidth and 1kHz noise are 100% tested for each n Common Mode Rejection: 112dB Min individual amplifier. Consequently, the specifications n Power Supply Rejection: 116dB Min of even the lowest cost grades (the LT1124C and the n Available in 8-Pin SO Package LT1125C) have been spectacularly improved compared to equivalent grades of competing amplifiers. a T Power consumption of the LT1124 is one-half of two n OP-27s. Low power and high performance in an 8-pin Two and Three Op Amp Instrumentation Amplifiers SO package make the LT1124 a first choice for surface n Low Noise Signal Processing mounted systems and where board space is restricted. n Active Filters n Microvolt Accuracy Threshold Detection For a decompensated version of these devices, with three n Strain Gauge Amplifiers times higher slew rate and bandwidth, please see the n Direct Coupled Audio Gain Stages LT1126/LT1127 data sheet. n Tape Head Preamplifiers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
