LT6370
25µV, 0.3µV/°C, Low Noise
Instrumentation Amplifier
DESCRIPTION
The LT®6370 is a gain programmable, high precision
instrumentation amplifier that delivers industry leading
DC precision. This high precision enables smaller signals
to be sensed and eases calibration requirements, particu-
larly over temperature.
The LT6370 uses a proprietary high performance bipolar
process which enables industry leading accuracy coupled
with exceptional long-term stability. The LT6370 is laser
trimmed for very low input offset voltage (25µV) and high
CMRR (94dB, G = 1). Proprietary on-chip test capability
allows the input offset voltage drift (0.3µV/°C) and gain
drift (30ppm/°C) to be guaranteed with automated testing
on the S8E package.
In addition to excellent DC specifications, the LT6370’s
wide bandwidth (3.1MHz, G = 1) and fast settling time
allow it to operate well in multiplexed applications. EMI
filtering is integrated on the LT6370’s inputs to maintain
accuracy in the presence of harsh RF interference.
The LT6370 is available in a compact 8-pin MSOP or S8E
which use the conventional instrumentation amplifier
pin-out as well as a 10-pin 3mm × 3mm DFN. The S8E
package is also offered as an A grade which has superior
DC specifications. The LT6370 is fully specified over the
–40°C to 85°C and –40°C to 125°C temperature ranges.
