UMW R LMV321/LMV358/LMV324 Low-Power rail-to-rail Operational Amplifier Description LMV321 (single channel) is a rail-to-rail input, output voltage feedback, low power consumption operational amplifier. It has wide input common mode voltage and output swing. The minimum working voltage can be up to 2.1V, and the maximum working voltage is recommended to be 5.5V. Used as power amplifier in all kinds of pocket or portable stereo radio recorders. LMV321 has the following characteristics:Can provide 1MHz gain bandwidth product. It has an extremely low input bias current (about 10pA TYP) and can be used for integration,photo diode amplifiers and piezoelectric sensors. The Rail to Rail input and output buffers are also used for specific IC designs in single power systems. Applications of this series of amplifiers include safety monitoring, portable devices, batteries and power supplies, supply control, signal processing and interfaces in low power sensor systems. The LMV321 single is available in Green SC70-5 and SOT23-5 packages. The LMV358 dual is available in Green SOP-8 and TSSOP-8 packages.The LMV324 Quad is available in Green SOP- 14 and TSSOP-14 packages.

The reliability of the device will also be affected if the device works under the limit conditions. Electrostatic discharge can also cause damage to chips, so it is suggested to take some preventive measures for integrated circuits. Failure to follow proper handling and installation can also cause damage. Precision LMV321 and other devices are more vulnerable to damage than ordinary devices in the case of tiny electrostatic, and small parameter changes may make the whole circuit performance substandard.

Make sure the filter is within the amplifier's bandwidth. Large feedback resistors are easily accompanied by parasitic capacitance at high speed, resulting in adverse effects such as oscillation. Keep the resistance value as low as possible and consider the appropriate output load. www.umw-ic.com 5 UTD Semiconductor Co.,Limited UMW R LMV321/LMV358/LMV324 Low-Power rail-to-rail Operational Amplifier SC70-5 Dimensions Dimensions In Millimeters In Inches Min Max Min Max A 0.900 1.100 0.035 0.043 A1 0.000 0.100 0.000 0.004 A2 0.900 1.000 0.035 0.039 b 0.150 0.350 0.006 0.014 C 0.080 0.150 0.003 0.006 D 2.000 2.200 0.079 0.087 E 1.150 1.350 0.045 0.053 E1 2.150 2.450 0.085 0.096 e 0.650TYP 0.026TYP e1 1.200 0.047 L 0.525REF 0.021REF L1 0.260 0.460 0.010 0.018 θ 0° 8° 0° 8° Symbol 1.400 0.055 SOT23-5 Dimensions Dimensions In Millimeters In Inches Min Max Min Max A 1.050 1.250 0.041 0.049 A1 0.000 0.100 0.000 0.004 A2 1.050 1.150 0.041 0.045 b 0.300 0.400 0.012 0.016 C 0.100 0.200 0.004 0.008 D 2.820 3.020 0.111 0.119 E 1.500 1.700 0.059 0.067 E1 2.650 2.950 0.104 0.116 e 0.950TYP 0.037TYP e1 1.800 0.071 L 0.700REF 0.028REF L1 0.300 0.460 0.012 0.024 θ 0° 8° 0° 8° Symbol www.umw-ic.com 6 2.000 0.079 UTD Semiconductor Co.,Limited UMW R LMV321/LMV358/LMV324 Low-Power rail-to-rail Operational Amplifier SOP-8 A2 C θ L1 A1 e E D Symbol E1 b www.umw-ic.com Dimensions In In Millimeters Inches Min Max Min Max A1 0.100 0.250 0.004 0.010 A2 1.350 1.550 0.053 0.061 b 0.330 0.510 0.013 0.020 C 0.190 0.250 0.007 0.010 D 4.780 5.000 0.188 0.197 E 3.800 4.000 0.150 0.157 E1 5.800 6.300 0.228 0.248 e 7 Dimensions 1.270 TYP 0.050 TYP L1 0.400 1.270 0.016 0.050 θ 0° 8° 0° 8° UTD Semiconductor Co.,Limited UMW R LMV321/LMV358/LMV324 Low-Power rail-to-rail Operational Amplifier TSSOP-8 Dimensions Dimensions In In Millimeters Inches Min Max Min Max A 0.800 1.200 0.031 0.047 A1 0.000 0.200 0.000 0.008 A2 0.760 0.970 0.030 0.038 b 0.30 TYP 0.012 TYP C 0.15 TYP 0.006 TYP D 2.900 e 0.65 TYP E 2.900 3.100 0.114 0.122 E1 4.700 5.100 0.185 0.201 L1 0.410 0.650 0.016 0.026 θ 0° 6° 0° 6° Symbol E E1 A A2 e b D 3.100 0.114 0.122 0.026 A1 R1 R θ L1 www.umw-ic.com L L2 8 UTD Semiconductor Co.,Limited UMW R LMV321/LMV358/LMV324 Low-Power rail-to-rail Operational Amplifier TSSOP-14 Dimensions E1 E A A2 e Symbol c D In Millimeters MIN TYP MAX A - - 1.20 A1 0.05 - 0.15 A2 0.90 1.00 1.05 b 0.20 - 0.28 c 0.10 - 0.19 D 4.86 4.96 5.06 E 6.20 6.40 6.60 E1 4.30 4.40 4.50 e L A1 R1 R 0.65 BSC 0.45 0.60 L1 1.00 REF L2 0.25 BSC 0.75 R 0.09 - - θ 0° - 8° θ L1 www.umw-ic.com L L2 9 UTD Semiconductor Co.,Limited UMW R LMV321/LMV358/LMV324 Low-Power rail-to-rail Operational Amplifier SOP-14 D E1 Dimensions E In Millimeters Symbol e b A A2 A1 MIN TYP MAX A 1.35 1.60 1.75 A1 0.10 0.15 0.25 A2 1.25 1.45 1.65 b 0.36 D 8.53 8.63 8.73 E 5.80 6.00 6.20 E1 3.80 3.90 4.00 e 1.27 BSC L 0.45 0.60 L1 1.04 REF L2 0.25 BSC θ L L1 0.49 0° 0.80 8° θ L2 ORDERING INFORMATION Order Code Package Baseqty Deliverymode UMW LMV321IDCKR SC70-5 3000 Tape and reel UMW LMV321IDBVR SOT23-5 3000 Tape and reel UMW LMV358IDR SOP-8 2500 Tape and reel UMW LMV358IPWR TSSOP-8 2000 Tape and reel UMW LMV324IDR SOP-14 2500 Tape and reel UMW LMV324IPWR TSSOP-14 2000 Tape and reel www.umw-ic.com 10 UTD Semiconductor Co.,Limited
