3 Description
The TLVx172 family of electromagnetic interference
(EMI)-hardened, 36-V, single-supply, low-noise
operational amplifiers (op amps) features a THD+N of
0.0002% at 1 kHz with the ability to operate on
supplies ranging from 4.5 V (±2.25 V) to 36 V
(±18 V). These features, along with low noise and
very high PSRR, make the TLVx172 an excellent
choice for microvolt-level signal amplification. The
TLVx172 family of devices offer good offset and drift,
a high bandwidth of 10 MHz, and a slew rate of
10 V/μs with only 2.3 mA (max) of quiescent current
over temperature.
Unlike most operational amplifiers that are specified
at only one supply voltage, the TLVx172 family of
operational amplifiers is specified from 4.5 V to 36 V.
Input signals beyond the supply rails do not cause
phase reversal. The TLVx172 family is stable with
capacitive loads up to 300 pF. The input can operate
100 mV below the negative rail and within 2 V of the
positive rail for normal operation. Note that these
devices can operate with a full rail-to-rail input
100 mV beyond the positive rail, but with reduced
performance within 2 V of the positive rail.
The TLVx172 operational amplifiers are specified
from –40°C to +125°C.
