The LPV511 is a micropower operational amplifier

(Typical at 3V Supply Unless Otherwise Noted)

that operates from a voltage supply range as wide as

• Wide Supply Voltage Range 2.7V to 12V

2.7V to 12V with ensured specifications at 3V, 5V and

• Slew Rate 7.7 V/ms

12V. The LPV511 exhibits an excellent speed to

power ratio, drawing only 880 nA of supply current

• Supply Current 880 nA

with a bandwidth of 27 kHz. These specifications

• Output Short Circuit Current 1.35 mA

make the LPV511 an ideal choice for battery powered

• Rail-to-Rail Input

systems that require long life through low supply

current, such as instrumentation, sensor conditioning

• Rail-to-Rail Output 100 mV from Rails

and battery current monitoring.

• Bandwidth (C

= 50 pF, R

= 1 MΩ) 27 kHz

The LPV511 has an input range that includes both

• Unity Gain Stable

supply rails for ground and high side battery sensing

applications. The LPV511 output swings within 100

APPLICATIONS

mV of either rail to maximize the signal's dynamic

• Battery Powered Systems

range in low supply applications. In addition, the

output is capable of sourcing 650 µA of current when

• Security Systems

• Micropower Thermostats

The LPV511 is fabricated on TI's advanced VIP50C

• Solar Powered Systems

process.

• Portable Instrumentation

The LPV511 is available in the space saving SC70

LPV511 SNOSAG7C – AUGUST 2005 – REVISED MARCH 2013 www.ti.com APPLICATION NOTES The LPV511 is fabricated with Texas Instrument's state-of-the-art VIP50C process. INPUT STAGE The LPV511 has a rail-to-rail input which provides more flexibility for the system designer. As can be seen from the simplified schematic, rail-to-rail input is achieved by using in parallel, one PNP differential pair and one NPN differential pair.

LPV511 www.ti.com SNOSAG7C – AUGUST 2005 – REVISED MARCH 2013 POWER SUPPLIES AND LAYOUT The LPV511 operates from a single 2.7V to 12V power supply. It is recommended to bypass the power supplies with a 0.1 μF ceramic capacitor placed close to the V+ and V− pins. Ground layout improves performance by decreasing the amount of stray capacitance and noise at the op amp's inputs and outputs.
