描述

The LMV93x-N-Q1 family (LMV931-N-Q1 single, LMV932-N-Q1 dual and LMV934-N-Q1 quad) are low-voltage, low-power operational amplifiers with AEC-Q100 Grade 1 qualification for automotive applications. The LMV93x-N-Q1 family operates from 1.8-V to 5.5-V supply voltages and have rail-to-rail input and output. The input common-mode voltage extends 200 mV beyond the supplies which enables user enhanced functionality beyond the supply voltage range. The output can swing rail-to-rail unloaded and within 105 mV from the rail with 600-Ω load at 1.8-V supply. The LMV93x-N-Q1 devices are optimized to work at 1.8 V, which make them ideal for portable two-cell, battery-powered systems and single-cell Li-Ion systems.

LMV93x-N-Q1 devices exhibit an excellent speed-power ratio, achieving 1.4-MHz gain bandwidth product at 1.8-V supply voltage with very low supply current. The LMV93x-N-Q1 devices can drive a 600-Ω load and up to 1000-pF capacitive load with minimal ringing. These devices also have a high DC gain of 101 dB, making them suitable for low-frequency applications.

The single LMV93x-N-Q1 is offered in space-saving 5-pin SC-70 and SOT-23 packages. The dual LMV932-N-Q1 is in a 8-pin SOIC package and the quad LMV934-N-Q1 is in a 14-pin TSSOP package. These small packages are ideal solutions for area constrained PC boards in automotive applications.
