TLVx172 Operational Amplifiers

Texas Instruments' 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 offers 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.
