LMV751 Low Noise, Low Vos, Single Op Amp
August 1999
LMV751
Low Noise, Low Vos, Single Op Amp
General Description
The LMV751 is a high performance CMOS operational am-
plifier intended for applications requiring low noise and low
input offset voltage. It offers modest bandwidth of 4.5MHz for
very low supply current and is unity gain stable.
The output stage is able to drive high capacitance, up to
1000pF and source or sink 8mA output current.
It is supplied in the space saving SOT23-5 Tiny package.
The LMV751 is designed to meet the demands of small size,
low power, and high performance required by cellular
phones and similar battery operated portable electronics.

Note 1:
Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2:
All limits are guaranteed by testing or statistical analysis
Note 3:
Human body model, 1.5kΩ in series with 100pF. Machine model, 200Ω in series with 1000pF.
Note 4:
The maximum power dissipation is a function of T
J
(max),
θ
JA
, and T
A
. The maximum allowable power dissipation at any ambient temperature is

. All numbers apply for packages soldered directly into a PC board.
Note 5:
Typical values represent the most likely parametric norm.
Note 6:
All numbers are typical, and apply to packages soldered directly onto PC board in still air.
