LMV934-N-Q1 - Automotive Quad 1.8V, RRIO Operational Amplifier

Updated : 2020-01-09 14:20:55
Description

The LMV93x-N-Q1 family (LMV931-N-Q1 single, LMV932-N-Q1 dual and LMV934-N-Q1 quad) arelow-voltage, low-power operational amplifiers with AEC-Q100 Grade 1 qualification for automotiveapplications. The LMV93x-N-Q1 family operates from 1.8-V to 5.5-V supply voltages and haverail-to-rail input and output. The input common-mode voltage extends 200 mV beyond the supplieswhich enables user enhanced functionality beyond the supply voltage range. The output can swingrail-to-rail unloaded and within 105 mV from the rail with 600-Ω load at 1.8-V supply. TheLMV93x-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 gainbandwidth product at 1.8-V supply voltage with very low supply current. The LMV93x-N-Q1 devices candrive a 600-Ω load and up to 1000-pF capacitive load with minimal ringing. These devices also havea 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. Thedual 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.
