DESCRIPTION
The LMP7707/LMP7708/LMP7709 devices are
single, dual, and quad low offset voltage, rail-to-rail
input and output precision amplifiers which each have
a CMOS input stage and a wide supply voltage
range. The LMP7707/LMP7708/LMP7709 are part of
the LMP™ precision amplifier family and are ideal for
sensor interface and other instrumentation
applications. These decompensated amplifiers are
stable at a gain of 6 and higher.
The ensured low offset voltage of less than ±200 µV
along with the ensured low input bias current of less
than ±1 pA make the LMP7707/LMP7708/LMP7709
ideal for precision applications. The
LMP7707/LMP7708/LMP7709 are built utilizing VIP50
technology, which allows the combination of a CMOS
input stage and a supply voltage range of 12V with
rail-to-rail common mode voltage capability. The
LMP7707/LMP7708/LMP7709 are the perfect choice
in many applications where conventional CMOS parts
cannot operate due to the voltage conditions.
The unique design of the rail-to-rail input stage of
each of the LMP7707/LMP7708/LMP7709
significantly reduces the CMRR glitch commonly
associated with rail-to-rail input amplifiers. Both sides
of the complimentary input stage have been trimmed,
thereby reducing the difference between the NMOS
and PMOS offsets. The output swings within 40 mV
of either rail to maximize the signal dynamic range in
applications requiring low supply voltage.
The LMP7707 is offered in the space-saving 5-pin
SOT-23 and 8-pin SOIC packages, the LMP7708 is
offered in the 8-pin VSSOP and 8-pin SOIC
packages, and the quad LMP7709 is offered in the
14-pin TSSOP and 14-pin SOIC packages. These
small packages are ideal solutions for area
constrained PC boards and portable electronics.
