| 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 Input common mode voltage range includes ground Internally frequency compensated for unity gain Large DC voltage gain : 100dB Wide bandwidth for unity gain : 1 MHz Very low power consumption Wide supply voltage range : Single : 3V ~ 30V, Dual : 1.5 ~ 15V Applications Transducer amplifier DC gain blocks Conventional operational amplifiers Ordering Information Type NO.
