LP358, LP2904
SLOS475A – AUGUST 2005 – REVISED MAY 2017
Ultra-Low Power Dual Operational Amplifiers
1 Features
1 Low Supply Current: 54 μA (Typical)
• Low Offset Voltage: 2 mV (Typical)
• Low Input Bias Current: 2 nA (Typical)
• Input Common-Mode to GND
• Wide Supply Voltage: 3 V < VCC < 32 V
• Pin Compatible With LM358 and LM2904
2 Applications
• LCD Displays
• Portable Instrumentation
• Sensor and Metering Equipment
• Consumer Electronics (MP3 Players, Toys)
• Power Supplies
3 Description
The LP358 and LP2904 devices are dual low-power
operational amplifiers especially suited for battery-
operated applications. Good input specifications and
wide supply-voltage range still are achieved despite
the ultra-low supply current. Single-supply operation
is achieved with an input common-mode range that
includes GND.
The LP358 and LP2904 devices are ideal in
applications where wide supply voltages and low
power are more important than speed and bandwidth.
These applications include portable instrumentation,
LCD displays, consumer electronics (MP3 players,
toys, and so forth), and power supplies.
