1 / 23 page 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 1 FEATURES DESCRIPTION The LMV921 Single/LMV922 Dual/LMV924 Quad are 2 • (Typical 1.8V Supply Values; Unless Otherwise ensured to operate from +1.8V to +5.0V supply Noted) voltages and have rail-to-rail input and output. This • Ensured 1.8V, 2.7V and 5V Specifications rail-to-rail operation enables the user to make full use • Rail-to-Rail Input & Output Swing of the entire supply voltage range. The input common mode voltage range extends 300mV beyond the • w/600 Ω Load 100 mV from Rail supplies and the output can swing rail-to-rail • w/2k Ω Load 30 mV from Rail unloaded and within 100mV from the rail with 600 Ω • VCM 300mV Beyond Rails load at 1.8V supply. The LMV921/LMV922/LMV924 are optimized to work at 1.8V which make them ideal • Supply Current 145µA/amplifier for portable two-cell battery-powered systems and • Gain Bandwidth Product 1MHz single cell Li-Ion systems. • LMV921 Maximum VOS 6mV The LMV921/LMV922/LMV924 exhibit excellent • 90dB Gain w/600 Ω Load speed-power ratio, achieving 1MHz gain bandwidth • LMV921 Available in Ultra Tiny, SC70-5 product at 1.8V supply voltage with very low supply Package current. The LMV921/LMV922/LMV924 are capable of driving 600 Ω load and up to 1000pF capacitive • LMV922 Available in VSSOP-8 Package load with minimal ringing. The • LMV924 Available in TSSOP-14 Package LMV921/LMV922/LMV924's high DC gain of 100dB makes them suitable for low frequency applications. APPLICATIONS The LMV921 (Single) is offered in a space saving • Cordless/Cellular Phones SC70–5 and SOT-23–5 packages. The SC70–5 package is only 2.0X2.1X1.0mm. These small • Laptops packages are ideal solutions for area constrained PC • PDAs boards and portable electronics such as cellphones • PCMCIA and PDAs. • Portable/Battery-Powered Electronic Equipment • Supply Current Monitoring • Battery Monitoring spacer Supply Current vs. Output Voltage Swing vs. Gain and Phase Margin Supply Voltage (LMV921) Supply Voltage vs. Frequency 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
