LP324-N/LP2902-N Micropower Quad Operational Amplifier

Check for Samples: LP2902-N, LP324-N

FEATURES

DESCRIPTION

The LP324-N series consists of four independent,

• Low Supply Current: 85μA (typ)

high gain internally compensated micropower

• Low Offset Voltage: 2mV (typ)

operational amplifiers. These amplifiers are specially

• Low Input Bias Current: 2nA (typ)

suited for operation in battery systems while

maintaining good input specifications, and extremely

• Input Vommon Mode to GND

low supply current drain. In addition, the LP324-N has

• Interfaces to CMOS Logic

an input common mode range, and output source

• Wide Supply Range: 3V < V

< 32V

range which includes ground, making it ideal in single

supply applications.

• Small Outline Package Available

• Pin-for-pin Compatible with LM324

These amplifiers are ideal in applications which

include portable instrumentation, battery backup

equipment, and other circuits which require good DC

performance and low supply current.

APPLICATION HINTS The LP324-N series is a micro-power pin-for-pin equivalent to the LM324 op amps. Power supply current, input bias current, and input offset current have all been reduced by a factor of 10 over the LM324.

LP2902-N, LP324-N www.ti.com SNOSBX6C – SEPTEMBER 1999 – REVISED MARCH 2013 The circuits presented in the section on typical applications emphasize operation on only a single power supply voltage. If complementary power supplies are available, all of the standard op amp circuits can be used. In general, introducing a pseudo-ground (a bias voltage reference to V+/2) will allow operation above and below this value in single power supply systems.
