LMC7101/LMC7101Q Tiny Low Power Operational Amplifier with Rail-to-Rail Input and Output
June 12, 2009
LMC7101/LMC7101Q
Tiny Low Power Operational Amplifier with Rail-to-Rail
Input and Output
General Description
The LMC7101 is a high performance CMOS operational am-
plifier available in the space saving 5-Pin SOT23 Tiny pack-
age. This makes the LMC7101 ideal for space and weight
critical designs. The performance is similar to a single ampli-
fier of the LMC6482/LMC6484 type, with rail-to-rail input and
output, high open loop gain, low distortion, and low supply
currents.
The main benefits of the Tiny package are most apparent in
small portable electronic devices, such as mobile phones,
pagers, notebook computers, personal digital assistants, and
PCMCIA cards. The tiny amplifiers can be placed on a board
where they are needed, simplifying board layout.
Features
■
Tiny 5-Pin SOT23 package saves space—typical circuit
■
■
■
■
■
■
■
layouts take half the space of 8-Pin SOIC designs
Guaranteed specs at 2.7V, 3V, 5V, 15V supplies
Typical supply current 0.5 mA at 5V
Typical total harmonic distortion of 0.01% at 5V
1.0 MHz gain-bandwidth
Similar to popular LMC6482/LMC6484
Rail-to-rail input and output
Temperature Range –40°C to 125°C (LMC7101Q)
