Original TLV4170IDR 36-V, Single-Supply, EMI-Hardened, Low-Power Operational Amplifiers for Cost-Sensitive Systems 14-SOIC

Product Descriptions

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 PERCENT 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.
