UA149 - QUAD OPERATIONAL AMPLIFIERS

Download the UA149 datasheet PDF. This datasheet also covers the UA148 variant, as both devices belong to the same quad operational amplifiers family and are provided as variant models within a single manufacturer datasheet.

General Description

- The .uA 148 series is a true quad .uA741.

It consists of four independent, high gain, internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar .uA741 operational amplifier.

Key Features

  • include input offset currents and input bias current which are much less than those of a standard . uA741. Also, excellent isolation between amplifiers has been achieved by independently biasing each amplifier and using layout techniques which mini.
  • mize thermal coupling. The . uA 149 series has the same features as the. uA 148 except that it is decompensated to give a gain bandwidth product of 4 MHz typical at a gain greater than.

It consists of four independent, high gain, internally compensated, low power operational amplifiers which have been designed to provide functional characteristics identical to those of the familiar .uA741 operational amplifier. In addition, the total supply current for all four amplifiers is comparable to the supply current of a single .uA741 type op amp. Other features include input offset currents and input bias current which are much less than those of a standard .uA741.
