Description

National’s LMV851/LMV852/LMV854 are CMOS input, low power op amp ICs, providing a low input bias current, a wide temperature range of −40°C to +125°C and exceptional performance, making them robust general purpose parts. Additionally, the LMV851/LMV852/LMV854 are EMI hardened to minimize any interference so they are ideal for EMI sensitive applications. The unity gain stable LMV851/LMV852/LMV854 feature 8 MHz of bandwidth while consuming only 0.4 mA of current per channel. These parts also maintain stability for capacitive loads as large as 200 pF. The LMV851/LMV852/LMV854 provide superior performance and economy in terms of power and space usage. This family of parts has a maximum input offset voltage of 1 mV, a rail-to-rail output stage and an input common-mode voltage range that includes ground. Over an operating supply range from 2.7V to 5.5V the LMV851/LMV852/LMV854 provide a CMRR of 92 dB, and a PSRR of 93 dB. The LMV851/LMV852/LMV854 are offered in the space saving 5-Pin SC70 package, the 8-Pin MSOP and the 14-Pin TSSOP package.

National's LMV851EVAL board is a CMOS input, low power op amp IC, providing a low input bias current, a wide temperature range of -40°C to +125°C and exceptional performance, making this IC a robust general purpose part.

To demonstrate the EMI robustness of the LMV851/LMV852/LMV854 and to be able to measure the parameter EMIRR, three evaluation boards have been developed; one for each device. This document describes the evaluation boards and explains how to perform EMIRR measurements. Focus is on one of the input pins as those are most sensitive to EMI. Based on symmetry considerations, it can be expected that both inputs have the same EMIRR. For reasons of simplicity of the required schematic the measurement on the IN+ pin is selected. A detailed description on EMI and EMIRR for the other pins can be found in Application Note AN-1698.

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

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.
