Product details
Overview
TLV2434AQDRQ1 from Texas Instruments is a quad-channel, rail-to-rail output, automotive-qualified operational amplifier with extended common-mode input range (0 V to 4.5 V at 5 V supply), low input offset voltage (≤950 μV max at 25°C), ultra-low supply current (150 μA per channel max), and 600 Ω output drive capability. It operates from 2.7 V to 10 V supplies and is used in battery management units, ADAS domain controllers, and brake systems.
For engineers reviewing the TLV2434AQDRQ1 datasheet, TLV2434AQDRQ1 pinout, TLV2434AQDRQ1 application, or TLV2434AQDRQ1 equivalent, key selection criteria include rail-to-rail output swing, extended CMVR without phase inversion, 125°C automotive temperature rating, low-noise (18 nV/√Hz typ. at 1 kHz), and SOIC-14 packaging for high-density analog signal conditioning.
Technical Context
The TLV2434AQDRQ1 implements Advanced LinCMOS™ process technology to achieve high input impedance (>1 TΩ common-mode and differential resistance), low bias current (1 pA typ.), and no phase inversion when inputs approach supply rails. Its architecture supports stable operation with capacitive loads up to 100 pF and delivers 0.25 V/μs slew rate at unity gain.
It is fully characterized across –40°C to +125°C and optimized for low-voltage, low-power precision amplification - particularly where interfacing with ADCs, driving 600 Ω telecom loads, or conditioning high-impedance sensor signals (e.g., piezoelectric transducers) in safety-critical automotive subsystems.
Key Specifications

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Amplifier A output | Rail-to-rail output capable of sourcing/sinking ±5 mA; connects directly to ADC input or next-stage buffer. |
| 1IN– | Amplifier A inverting input | High-impedance node (1 TΩ); requires guarded layout to minimize leakage-induced offset drift. |
| 1IN+ | Amplifier A non-inverting input | Accepts common-mode voltages down to VDD– (ground) and up to VDD+ – 0.5 V; no phase inversion. |
| VDD+ | Positive supply rail | Supports single-supply operation from 2.7 V to 10 V; decoupling capacitor required within 5 mm. |
| 2IN+ | Amplifier B non-inverting input | Identical CMVR and bias specs as 1IN+; enables matched dual-sensor front-end designs. |
| 2IN– | Amplifier B inverting input | Matched to 1IN–; supports differential configurations with <10 μV inter-channel offset mismatch. |
