LM1558/LM1458 Dual Operational Amplifier

General Description

The LM1558 and the LM1458 are general purpose dual op-

erational amplifiers. The two amplifiers share a common

bias network and power supply leads. Otherwise, their oper-

ation is completely independent.

The LM1458 is identical to the LM1558 except that the

LM1458 has its specifications guaranteed over the tempera-

ture range from 0 § Cto a 70 § C instead of b 55 § Cto

a 125 § C.

Features

Y No frequency compensation required

Y Short-circuit protection

Y Wide common-mode and differential voltage ranges

Y Low-power consumption

Y 8-lead can and 8-lead mini DIP

Y No latch up when input common mode range is

exceeded

Note 1: The maximum junction temperature of the LM1558 is 150 § C, while that of the LM1458 is 100 § C. For operating at elevated temperatures, devices in the H08

package must be derated based on a thermal resistance of 150 § C/W, junction to ambient or 20 § C/W, junction to case. For the DIP the device must be derated

based on a thermal resistance of 187 § C/W, junction to ambient.

Note 2: For supply voltages less than g 15V, the absolute maximum input voltage is equal to the supply voltage.

Note 3: These specifications apply for V S e g 15V and b 55 § C s T A s 125 § C, unless otherwise specified. With the LM1458, however, all specifications are limited

to 0 § C s T A s 70 § C and V S e g 15V.

Note 4: Refer to RETS 1558V for LM1558J and LM1558H military specifications.

Note 5: Human body model, 1.5 k X in series with 100 pF.
