LMC7101
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 SOT 23-5 Tiny package.
This makes the LMC7101 ideal for space and weight critical
designs. The performance is similar to a single amplifier of
the LMC6482/4 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
n Tiny SOT23-5 package saves space — typical circuit
layouts take half the space of SO-8 designs
n Guaranteed specs at 2.7V, 3V, 5V, 15V supplies
n Typical supply current 0.5 mA at 5V
n Typical total harmonic distortion of 0.01% at 5V
n 1.0 MHz gain-bandwidth
n Similar to popular LMC6482/4
n Input common-mode range includes V− and V+
n Tiny package outside dimensions — 120 x 118 x 56 mils,
3.05 x 3.00 x 1.43 mm
Applications
n Mobile communications
n Notebooks and PDAs
n Battery powered products
n Sensor interface
