SUNTAC STC358

STC358 Low Power Dual OP AMP
Description
The STC358 consists of two independent high gain Internally frequency compensated
operational amplifiers designed to operate from a single power supply over a wide
range of voltage.
Features
ԦInput common mode voltage range includes ground
ԦInternally frequency compensated for unity gain
ԦLarge DC voltage gain : 100dB
ԦWide bandwidth for unity gain : 1 MHz
ԦVery low power consumption
ԦWide supply voltage range : Single : 3V ~ 30V, Dual : ±1.5 ~ ±15V
Applications
ԦTransducer amplifier
ԦDC gain blocks
ԦConventional operational amplifiers
