3 Description

The TLV2172-Q1 operational amplifier 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, enable the TLV2172-Q1 to amplify microvolt-level signals in applications such as HEV and EV automobiles and power trains, medical instrumentation, and more. The TLV2172-Q1 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 TLV2172-Q1 device is specified from 4.5 V to 36 V. Input signals beyond the supply rails do not cause phase reversal. The TLV2172-Q1 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 TLV2172-Q1 op amp is specified from –40°C to +125°C.
