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 power-supply rejection ratio (PSRR), make the single-channel TLV170, dual-channel TLV2170, and quad-channel 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 current-to-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.
