3 Description
The TLVx170 family of electromagnetic interference
(EMI)-hardened, 36-V, single-supply, low-noise
operational amplifiers (op amps) have a THD+N of
0.0002% at 1 kHz and can operate on supplies that
range from 2.7 V (±1.35 V) to 36 V (±18V). These
features, along with low noise and very high powersupply
rejection ratio (PSRR), make the singlechannel
TLV170, dual-channel TLV2170, and quadchannel
TLV4170 suitable for use in microvolt-level
signal amplification. The TLVx170 family of devices
also gives good offset, drift, and bandwidth with low
quiescent current.
Unlike most op amps that are specified at only one
supply voltage, the TLVx170 family of op amps is
specified from 2.7 V to 36 V with the ability to swing
input signals beyond the supply rails without phase
reversal. The TLVx170 family is also unity-gain stable
with a 200-pF capacitive load with a 1.2-MHz
bandwidth and a 0.4-V/μs slew rate for use in currentto-
voltage converters.
The device inputs can operate 100 mV below the
negative rail and within 2 V of the positive rail for
normal operation, and with full rail-to-rail input with
reduced performance. The TLVx170 devices are
specified from –40°C to +125°C.
