AN1101SSM
CMOS single power supply
■ Overview
AN1101SSM is an operational amplifier with a single
power supply by CMOS diffusion process.
It has low current-consumption compared to general
purpose operational amplifier by bipolar diffusion process.
0 V to V
DD
is available for both input voltage and output
voltage. And this IC is widely applicable to the buttery-
driven equipment and to many amplifier circuits which
adopt small package products.
■ Features
• Low current-consumption: I
DD
= 55 µA (typ.), V
DD
= 3 V
• Operating input/output voltage range: 0 V to V
DD
• Small offset voltage: 0.5 mV (typ.)
• Small input bias current: 1 pA (typ.)
• Operating supply voltage range:
2.5 V to 5.5 V or ±1.25 V to ±2.75 V
■ Applications
• Various small-size general consumer electronics equipment
