Dual Operational Amplifier
Features Description
" Internally Frequency Compensated for Unity Gain The KA258 series consist of two independent, high gain,
" Large DC Voltage Gain: 100dB internally frequency compensated operational amplifiers
" Wide Power Supply Range: which were designed specifically to operate from a single
KA258/KA258A, KA358/KA358A: 3V ~ 32V (or power supply over a wide range of voltage. Operation from
Ä…1.5V~ 16V) split power supplies is also possible and the low power
KA2904 : 3V~26V (or Ä…1.5V ~ 13V) supply current drain is independent of the magnitude of the
" Input Common Mode Voltage Range Includes Ground power supply voltage. Application areas include transducer
" Large Output Voltage Swing: 0V DC to Vcc - 1.5V DC amplifier, DC gain blocks and all the conventional OP-AMP
" Power Drain Suitable for Battery Operation. circuits which now can be easily implemented in single
power supply systems.
