Features, Applications

Internally Compensated, High Performance Dual Operational Amplifiers

The MC1458, C was designed for use as a summing amplifier, integrator, or amplifier with operating characteristics as a function of the external feedback components. No Frequency Compensation Required Short Circuit Protection Wide Common Mode and Differential Voltage Ranges Low Power Consumption No LatchUp

Rating Power Supply Voltage Input Differential Voltage Input Common Mode Voltage (Note 1) Output Short Circuit Duration (Note 2) Operating Ambient Temperature Range Storage Temperature Range Junction Temperature Symbol VCC VEE VID VICM tSC TA Tstg TJ Value Continuous 150 C Unit Vdc V

NOTES: 1. For supply voltages less than 15 V, the absolute maximum input voltage is equal to the supply voltage. 2. Supply voltage equal to or less than 15 V.

ELECTRICAL CHARACTERISTICS (VCC +15 V, VEE = 25C, unless otherwise noted. (Note 3))
ELECTRICAL CHARACTERISTICS (VCC +15 V, VEE TA = Thigh to Tlow, unless otherwise noted. (Note 3))*

MC1458 Characteristic Input Offset Voltage (RS 10 k) Input Offset Current (TA to +70C) Input Bias Current (TA to +70C) Output Voltage Swing (Rs 10 k) (Rs 2 k) Large Signal Voltage Gain (VO 2 k) (VO 10 k)

3. Input pins of an unused amplifier must be grounded for split supply operation or biased at least 3.0 V above V EE for single supply operation.

Unlike conventional peak reading or RMS meters, this system was especially designed to provide the quick response time essential to burst (popcorn) noise testing.

The test time employed is 10 sec and the 20 V peak limit refers to the operational amplifier input thus eliminating errors in the closed loop gain factor of the operational amplifier.
