NCS7101
1.8 Volt Rail−to−Rail
Operational Amplifier
The NCS7101 operational amplifier provides rail−to−rail operation
on both the input and output. The output can swing within 50 mV of
each rail. This rail−to−rail operation enables the user to make full use
of the entire supply voltage range available. It is designed to work at
very low supply voltages (1.8 V and ground), yet can operate with a
supply of up to 10 V and ground. The NCS7101 is available in the
space saving SOT−23−5 package with two industry standard pinouts.
Features
• Low Voltage, Single Supply Operation (1.8 V and Ground to 10 V
and Ground)
• 1.0 pA Input Bias Current
• Unity Gain Bandwidth of 1.0 MHz at 5.0 V,
0.9 MHz at 1.8 V
• Output Voltage Swings Within 50 mV of Both Rails @ 1.8 V
• No Phase Reversal on the Output for Over−Driven Input Signals
• Input Offset Trimmed to 1.0 mV
• Low Supply Current (ID = 1.0 mA)
• Works Down to Two Discharged NiCd Battery Cells
• ESD Protected Inputs Up to 2.0 kV
• Pb−Free Package is Available
Typical Applications
• Dual NiCd/NiMH Cell Powered Systems
• Portable Communication Devices
• Low Voltage Active Filters
• Power Supply Monitor and Control
• Interface to DSP
