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.
