General Description
The HT9251/HT9252/HT9254 family of operational
amplifiers offer the benefits of operating with a single
supply voltage as low as 1.8V and with a supply
current of 50μA/amplifier. The devices also provide full
rail-to-rail input and output operation. The device range
has a gain bandwidth product of 550kHz and is unity
gain stable. Available in singe, dual and quad versions,
along with a range of package types, this range of Low
Voltage Operational Amplifiers will find excellent use
in a wide range of applications for portable devices and
battery powered equipment.
Applications
• Automotive Applications
• Portable Equipment
• Photodiode Amplifiers
• Analog Filters
• Battery Powered Systems
