gain set.
Note 1:
An LM4871LD that has been properly mounted to a circuit board will deliver 3W into 3W
(at 10% THD). The other package options for the LM4871 will deliver 1.5W into 8W (at 10% THD).
See the
Application Information
sections for further information concerning the LM4871LD,
LM4871MM, LM4871M, and the LM4871N.

LMV821
The LMV821/LMV822/LMV824 bring performance and economy to low voltage low power
systems. With a 5 MHz unity-gain frequency and a guaranteed 1.4 V/
µ
s slew rate, the quiescent
current is only 220
µ
A/amplifier (2.7 V). They provide rail-to-rail (R-to-R) output swing into heavy
loads (600
Ω
Guarantees). The input common-mode voltage range includes ground, and the
maximum input offset voltage is 3.5mV (Guaranteed). They are also capable of comfortably driving
large capacitive loads (refer to the application notes section).
The LMV821 (single) is available in the ultra tiny SC70-5 package, which is about half the size of
the previous title holder, the SOT23-5.
Overall, the LMV821/LMV822/LMV824 (Single/Dual/Quad) are low voltage, low power,
performance op amps, that can be designed into a wide range of applications, at an economical price.
