3 Description
TI’s LMV83x devices are CMOS input, low-power
operation amplifier ICs, providing a low input bias
current, a wide temperature range of −40°C to 125°C,
and exceptional performance, making them robust
general-purpose parts. Additionally, the LMV83x are
EMI-hardened to minimize any interference, making
them ideal for EMI-sensitive applications.
The unity gain stable LMV83x feature 3.3-MHz of
bandwidth while consuming only 0.24 mA of current
per channel. These parts also maintain stability for
capacitive loads as large as 200 pF. The LMV83x
provide superior performance and economy in terms
of power and space usage.
This family of parts has a maximum input offset
voltage of 1 mV, a rail-to-rail output stage and an
input common-mode voltage range that includes
ground. Over an operating range from 2.7 V to 5.5 V,
the LMV83x provide a PSRR of 93 dB, and a CMRR
of 91 dB. The LMV831 is offered in the space-saving
5-pin SC70 package, the LMV832 in the 8-pin
VSSOP and the LMV834 is offered in the 14--in
TSSOP package.
