Description

The LPV511 is a micropower operational amplifier that operates from a voltage supply range as wide as 2.7V to 12V with guaranteed specifications at 3V, 5V and 12V. The LPV511 exhibits an excellent speed to power ratio, drawing only 880 nA of supply current with a bandwidth of 27 kHz. These specifications make the LPV511 an ideal choice for battery powered systems that require long life through low supply current, such as instrumentation, sensor conditioning and battery current monitoring.

The LPV511 has an input range that includes both supply rails for ground and high side battery sensing applications. The LPV511 output swings within 100 mV of either rail to maximize the signal's dynamic range in low supply applications. In addition, the output is capable of sourcing 650 µA of current when powered by a 12V battery.

The LPV511 is fabricated on National's advanced VIP50C process.

The LPV511 is available in the space saving SC70 package which makes it ideal for portable electronics with area constrained PC boards.

Description:

National Semiconductor offers this blank universal Evaluation Board to help you evaluate the performance of any low voltage, low power operational amplifier that is offered in the SC-70 package. Resistors, capacitors, or any other components can be easily mounted on this board. These components can be chosen from any of the following three popular sizes: 1206, 0805, and, 0603. The op amp can then be tested under the conditions of your choice.

The 551012922-001 Evaluation Board allows quick and easy evaluation of the part. You need only supply an analog input signaland a power supply to the evaluation board.

Features:

  • Universal for all low voltage, low power op amps.
  • Dual sided layout for different pin-outs.
  • Accommodates components of any of these sizes:
         1206
         0805
         0603
  • Quick and easy evaluation.

Reliability Metrics

LPV511MGXVIP50CLZ301755003150001289382110

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
