DescripTion
Zero Drift, Precision
Instrumentation Amplifier with
Digitally Programmable Gain
The LTC6915 is a precision programmable gain instru-
mentation amplifier. The gain can be programmed to 0,
1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, or 4096
through a parallel or serial interface. The CMRR is typi-
cally 125dB with a single 5V supply with any programmed
gain. The offset is below 10V with a temperature drift of
less than 50nV/°C.
The LTC6915 uses charge balanced sampled data tech-
niques to convert a differential input voltage into a single
ended signal that is in turn amplified by a zero-drift op-
erational amplifier.
The differential inputs operate from rail-to-rail and the
single-ended output swings from rail-to-rail. The LTC6915
can be used in single power supply applications as low as
2.7V, or with dual ±5V supplies. The LTC6915 is available
in a 16-lead SSOP package and a 12-lead DFN surface
mount package.
