Product details
Overview
TLV2432AQDRQ1 from Texas Instruments is a dual-channel, rail-to-rail output, automotive-qualified operational amplifier optimized for low-voltage (2.7 V to 10 V) operation. It delivers 18 nV/√Hz input voltage noise at 1 kHz, 950 μV max input offset voltage at 25°C, and 125 μA max supply current per channel - enabling precision signal conditioning in battery management units and ADAS domain controllers.
For engineers reviewing the TLV2432AQDRQ1 datasheet, TLV2432AQDRQ1 pinout, TLV2432AQDRQ1 application, or TLV2432AQDRQ1 equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V at 5 V supply), no phase inversion behavior, 600 Ω output drive capability, and AEC-Q100 Grade 1 qualification (–40°C to +125°C).
Technical Context
The TLV2432AQDRQ1 employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typical) and high input impedance (>1 TΩ), making it suitable for interfacing with high-impedance sensors such as piezoelectric transducers. Its rail-to-rail output swing supports full dynamic range utilization when driving ADCs in single-supply systems.
This device operates without phase inversion even when common-mode input voltage reaches the supply rails, eliminating need for costly rail-to-rail input amplifiers in many automotive sensing applications. It is fully characterized across –40°C to +125°C and specified for stable operation with capacitive loads up to 100 pF.

FAQ
What is the maximum operating temperature for TLV2432AQDRQ1?
The TLV2432AQDRQ1 is qualified for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for under-hood and domain controller environments. This rating is verified per TI's production test flow and applies to all electrical parameters listed in the datasheet under recommended operating conditions.
Does TLV2432AQDRQ1 support rail-to-rail input?
No, TLV2432AQDRQ1 features rail-to-rail *output* but not rail-to-rail input. Its common-mode input voltage range extends from VDD– to VDD+ – 0.5 V (e.g., 0 V to 4.5 V at 5 V supply). It does not accept inputs at the positive rail, unlike true rail-to-rail input amplifiers such as the OPA2333AQPWRQ1.
Can TLV2432AQDRQ1 drive a 100 pF capacitive load stably?
Yes, TLV2432AQDRQ1 is characterized for stable unity-gain operation with up to 100 pF capacitive load, as confirmed by phase margin (66°) and gain margin (11 dB) measurements at 5 V supply. Layout best practices - including short traces and local bypass capacitors - are still required to maintain stability in production designs.
What is the meaning of "2432AQ" top-side marking on TLV2432AQDRQ1?
"2432AQ" is the standardized TI top-side marking for the TLV2432AQDRQ1 device, indicating the TLV2432A-Q1 variant in SOIC-8 package. The "A" denotes the 950 μV max input offset voltage grade, "Q" confirms automotive qualification, and "2432" identifies the base product family - consistent across TI's orderable part number and physical device labeling.
Is TLV2432AQDRQ1 pin-compatible with TLV2432QDRQ1?
Yes, TLV2432AQDRQ1 and TLV2432QDRQ1 share identical SOIC-8 (D) package dimensions, pinout, and footprint. They differ only in input offset voltage specification (950 μV max vs. 2.5 mV max) and top-side marking ("2432AQ" vs. "2432Q1"), allowing direct substitution in existing layouts without PCB changes.
