DESCRIPTION
The OPA170 is a 36-V, single-supply, low-noise
operational amplifier that features a micro package
with the ability to operate on supplies ranging from
+2.7V (±1.35V) to +36V (±18V). It offers good offset,
drift, and bandwidth with low quiescent current.
Unlike most op amps, which are specified at only one
supply voltage, the OPA170 is specified from +2.7V
to +36V. Input signals beyond the supply rails do not
cause phase reversal. The OPA170 is stable with
capacitive loads up to 300pF. The input can operate
100mV below the negative rail and within 2V of the
positive rail for normal operation. Note that these
devices can operate with full rail-to-rail input 100mV
beyond the positive rail, but with reduced
performance within 2V of the positive rail.
The OPA170 is available in the SOT553-5 package
and is specified from –40°C to +150°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
