OBSOLETE LMV921, LMV922, LMV924 www.ti.com SNOS436H – AUGUST 2000 – REVISED APRIL 2013 LMV921/LMV922/LMV924 Single, Dual and Quad 1.8V, 1MHz, Low Power Operational Amplifiers with Rail-To-Rail Input and Output Check for Samples: LMV921, LMV922, LMV924 FEATURES 1 2 (Typical 1.8V Supply Values; Unless Otherwise Noted) Ensured 1.8V, 2.7V and 5V Specifications Rail-to-Rail Input & Output Swing w/600Ω Load 100 mV from Rail w/2kΩ Load 30 mV from Rail VCM 300mV Beyond Rails Supply Current 145µA/amplifier Gain Bandwidth Product 1MHz LMV921 Maximum VOS 6mV 90dB Gain w/600Ω Load LMV921 Available in Ultra Tiny, SC70-5 Package LMV922 Available in VSSOP-8 Package LMV924 Available in TSSOP-14 Package APPLICATIONS Cordless/Cellular Phones Laptops PDAs PCMCIA Portable/Battery-Powered Electronic Equipment Supply Current Monitoring Battery Monitoring DESCRIPTION The LMV921 Single/LMV922 Dual/LMV924 Quad are ensured to operate from +1.8V to +5.0V supply voltages and have rail-to-rail input and output. This rail-to-rail operation enables the user to make full use of the entire supply voltage range. The input common mode voltage range extends 300mV beyond the supplies and the output can swing rail-to-rail unloaded and within 100mV from the rail with 600Ω load at 1.8V supply. The LMV921/LMV922/LMV924 are optimized to work at 1.8V which make them ideal for portable two-cell battery-powered systems and single cell Li-Ion systems. The LMV921/LMV922/LMV924 ...
