NJM1458

The NJM1458 is a kind of monolithic pair of internally compensated high performance amplifiers, constructed using the new JRC planar epitaxial process. The devic is intended for a wide range of analog applications where board space or weight are important. The NJM1458 is short-circuit and require no external components for frequency compensation. The internal 6 dB/octabe roll-off insures stability in closed loop applications. There are some features of NJM1458 as follows: (1)operating voltage; +3 to +18 V; (2)output short-circuit protection; (3)package outline: DIP8, DMP8; (4)bipolar technology.

What comes next is about the absolute maximum ratings of NJM1458: (1)supply voltage, V+/V-: ±18 V; (2)input voltage, VI: ±15 V; (3)differential input voltage, VID: ±30 V; (4)power dissipation, PD: 500 mW (DIP8) and 300 mW (DMP8); (5)operating temperature range, Topr: -20 to +75; (6)storage temperature range, Topr: -40 to +125.

The following is about the eletrical characteristics of NJM1458: (1)input offset voltage, VIO: 2.0 mV typ and 6.0 mV max when RS10 k; (2)input offset current, IIO: 5 nA typ and 200 nA max; (3)input bias current, IB: 30 nA typ and 500 nA max; (4)input resistance, RIN: 0.3 M min and 1.0 M typ; (5)large-signal voltage gain, AV: 86 dB min and 106 dB typ at RL2 k, VO=±10 V; (6)common mode rejection ratio, CMR: 70 dB min and 90 dB typ at RS10 k; (7)supply voltage rejection ratio, SVR: 76.5 dB min and 90 dB typ at RS10 k; (8)operating current, ICC: 3.3 mA typ and 5.7 mA max; (9)slew rate, SR: 0.5 V/s typ at RL2 k, AV=1.
