3 Description

The LMC6035 and LMC6036 (LMC603x) are

economical, low-voltage op amps capable of rail-torail

output swing into loads of 600Ω. The LMC6035

is available in a chip-sized package (8-bump DSBGA)

using micro SMD package technology. Both devices

allow for single-supply operation and are specified

for 2.7V, 3V, 5V, and 15V supply voltage. The

2.7V supply voltage corresponds to the end-of-life

voltage (0.9V/cell) for three NiCd or NiMH batteries

in series, making the LMC603x an excellent choice for

portable and rechargeable systems. These devices

also feature a well behaved decrease in specifications

at supply voltages less than the specified 2.7V

operation. This behavior provides a comfort zone

for adequate operation at voltages significantly less

than 2.7V. The ultra-low input current makes these

devices an excellent choice for low-power, activefilter

applications because a low input bias current

allows the use of higher resistor values and lower

capacitor values. In addition, the drive capability of

the LMC603x makes these op amps an excellent

choice in a broad range of applications for low-voltage

systems.
