TLV2172QDGKRQ1

The TLV2172-Q1 op amp features 0.0002% THD+N at 1kHz, with a supply voltage range of 4.5V (±2.25V) to 36V (±18V). These characteristics, combined with low noise and ultra-high PSRR, make the TLV2172-Q1 well suited for amplifying millivolt-level signals in applications such as HEV and EV automotive and powertrain systems, and medical instrumentation. The TLV2172-Q1 offers excellent offset and drift, 10MHz bandwidth, 10V/μs slew rate, and a quiescent current of only 2.3mA (maximum) over temperature. Unlike most op amps that are specified at only a single supply voltage, the TLV2172-Q1 is rated for operation across the full 4.5V to 36V supply range. Input signals that exceed the supply rails do not cause phase reversal. The TLV2172-Q1 remains stable with capacitive loads up to 300pF. The inputs operate correctly from 100mV below the negative supply rail to within 2V of the positive supply rail. Note that this device family supports a full rail-to-rail input range extending 100mV beyond the positive supply rail; however, performance is degraded when operating within 2V of the positive supply rail. The TLV2172-Q1 op amp is rated for operation over a temperature range of -40°C to +125°C.
