LT1168
1168fa
Low Power, Single
Resistor Gain Programmable,
Precision Instrumentation Amplifier
TheLT
1168isamicropower,precisioninstrumentationam-
plifier that requires only one external resistor to set gains of
1 to 10,000. The low voltage noise of 10nV/
√Hz (at 1kHz) is
notcompromisedbylowpowerdissipation(350
Atypicalfor
±15Vsupplies).Thewidesupplyrangeof±2.3Vto±18Vallows
the LT1168 to fit into a wide variety of industrial as well as
battery-powered applications.
ThehighaccuracyoftheLT1168isduetoa20ppmmaximum
nonlinearityand0.4%maxgainerror(G=10).Previousmono-
lithic instrumentation amps cannot handle a 2k load resistor
whereas the nonlinearity of the LT1168 is specified for loads
as low as 2k. The LT1168 is laser trimmed for very low input
offsetvoltage(40
Vmax),drift(0.3V/°C),highCMRR(90dB,
G = 1) and PSRR (103dB, G = 1). Low input bias currents of
250pA max are achieved with the use of superbeta process-
ing. The output can handle capacitive loads up to 1000pF in
any gain configuration while the inputs are ESD protected up
to 13kV (human body). The LT1168 with two external 5k
resistors passes the IEC 1000-4-2 level 4 specification.
The LT1168 is a pin-for-pin improved second source for the
AD620 and INA118. The LT1168, offered in 8-pin PDIP and
SO packages, requires significantly less PC board area than
discrete op amp resistor designs. These advantages make
the LT1168 the most cost effective solution for precision
instrumentation amplifier applications.
