Rev. 1.0.1

Features

• Inter na l ly frequ enc y co mp e nsa te d for unity gain

• Large DC voltage gain: 100dB

• Wide power supply r ange:

KA258/KA258A, KA358/KA358A: 3V~32V (or

±1.5V~16V)

KA2904 : 3V~26V (or ±1 .5V~13V)

• Input common mode voltage range Includes ground

• Large output voltage swing: 0V DC to Vcc - 1.5V DC

• Power drain suita ble for batt ery opera tion.

Description

The KA258 series consist of two independent, high gain,

internally frequency compensated operational amplifiers

which were designed specifically to operate from a single

power supply over a wide range of voltage. Operation from

split power supplies is also possible and the low power

supply current drain is independent of the magnitude of the

power Supply voltage. Application areas include

transducer amplifier, DC gain blocks and all the

conventional OP amp circuits which now can be easily

implemented in single power Supply systems.
