The TLV2172QDGKRQ1 is a dual-channel, 36-V, single-supply operational amplifier from Texas Instruments, engineered for cost-sensitive automotive and industrial systems that demand precision amplification of microvolt-level signals. This AEC-Q100 qualified amplifier operates from 4.5 V (±2.25 V) to 36 V (±18 V), combining a 10-MHz gain bandwidth, 10-V/µs slew rate, and 0.0002% THD+N at 1 kHz with low 9-nV/√Hz noise and only 2.3 mA of maximum quiescent current over temperature.This EMI-hardened, low-noise automotive op amp features rail-to-rail output swing, an input common-mode range that includes the negative supply, and no phase reversal for inputs beyond the rails, making it a robust signal-conditioning building block for HEV/EV power trains, current sensing, and precision instrumentation.
Application Scenarios
● HEV and EV power trains: amplifying microvolt-level shunt signals for battery current monitoring and motor-control feedback.
● Advanced driver assistance systems (ADAS): serving as a precision signal conditioner for radar, camera, and ultrasonic sensor front ends.
● Automotive climate control and body electronics: conditioning temperature, pressure, and position sensor outputs on 12-V rails.
● Avionics and portable medical instrumentation: high-fidelity analog signal chains requiring low distortion and wide supply headroom.
● General-purpose analog building blocks: active filters, ADC buffers, TFT-LCD drive circuits, and touch-screen display interfaces.
FAQ
Q: Does the TLV2172QDGKRQ1 exhibit phase reversal when inputs exceed the rails? A: No, input signals beyond the supply rails do not cause phase reversal, protecting downstream circuitry during fault conditions.
Q: What is the maximum capacitive load it can drive directly? A: The device remains stable with capacitive loads up to 300 pF; for larger loads, add an isolation resistor or an R-C snubber at the output.
Alternative operational amplifier Models
● OPA2172-Q1: A higher-precision dual op amp with lower offset voltage and drift in the same VSSOP-8 footprint, suited for tighter-accuracy automotive signal chains.
● TLV4172-Q1: The quad-channel counterpart offering four 36-V amplifiers in a single package, ideal for space-efficient multi-signal conditioning.
● TLV172-Q1: The single-channel version in a compact SOT-23 (DBV) package, fitting discrete single-gain stages in dense layouts.
● TLV2462-Q1: A rail-to-rail input/output amplifier with shutdown, providing 6.4-MHz bandwidth and power-saving standby for battery-conscious nodes.
