The 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 (±18V). These features, along with low noise and very high PSRR, enable the TLVx172 to amplify microvolt-level signals in applications such as HEV and EV automobiles and power trains, medical instrumentation, and more. The TLVx172 device offers good offset and drift, a high bandwidth of 10 MHz, and a slew rate of 10 V/µs with only 2.3 mA of quiescent current over temperature (maximum).
Unlike most op amps that are specified at only one supply voltage, the TLVx172 device is specified from 4.5 V to 36 V. Input signals beyond the supply rails do not cause phase reversal. TLVx172 device 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 the device 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 op amp is specified from –40°C to +125°C.
