Product details
Overview
TLV2434AQPWRQ1 from Texas Instruments is a quad-channel, automotive-grade rail-to-rail output operational amplifier with 950 μV maximum input offset voltage at 25°C, 125 μA maximum supply current per channel, and extended common-mode input range (0 V to 4.5 V at 5 V supply). It operates from 2.7 V to 10 V, supports –40°C to 125°C ambient, and delivers 600 Ω load drive - enabling precision signal conditioning in battery management units and ADAS domain controllers.
For engineers reviewing the TLV2434AQPWRQ1 datasheet, TLV2434AQPWRQ1 pinout, TLV2434AQPWRQ1 application, or TLV2434AQPWRQ1 equivalent, key selection criteria include guaranteed A-grade offset performance across automotive temperature range, SOIC/TSSOP package compatibility for legacy and space-constrained layouts, rail-to-rail output swing without phase inversion, and validated ESD robustness (>2000 V HBM).
Technical Context
The TLV2434AQPWRQ1 implements Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typical) and high input impedance (1000 GΩ), making it suitable for interfacing with high-impedance sensors and piezoelectric transducers. Its extended common-mode input range (down to VDD– and up to VDD+ – 0.5 V) and rail-to-rail output swing (within 20 mV of rails at 3 mA load) eliminate need for level-shifting in single-supply systems.
This device features no phase inversion under overdrive conditions and maintains stable unity-gain operation with ≥62° phase margin into 2 kΩ//100 pF loads. It is fully characterized at 3 V and 5 V supplies, optimized for low-voltage, low-power automotive applications requiring long-term offset stability (0.003 μV/month drift) and high CMRR (≥63 dB) over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide automotive battery voltage variation including cold-crank and load-dump conditions. |
| Input Offset Voltage (max) | 950 μV at TA = 25°C - enables accurate DC-coupled amplification in precision sensor front-ends without trimming. |
| Supply Current (per channel) | 150 μA maximum at TA = 25°C - allows four-channel operation below 600 μA total, critical for always-on vehicle subsystems. |
| Common-Mode Input Range | 0 V to 4.5 V (min) at VDD = 5 V - accommodates signals near ground or rail without clipping in single-supply configurations. |
| Output Drive Capability | ±3 mA into 600 Ω - sufficient to directly drive ADC reference buffers or analog multiplexer inputs without external gain stages. |
| Input Bias Current | 1 pA typical - minimizes voltage error across high-value source impedances (>1 MΩ), preserving signal integrity in remote sensing. |
| ESD Rating (HBM) | >2000 V - exceeds AEC-Q100 stress test requirements for automotive electronics reliability. |
Pinout & Package
TSSOP-14 (PW) package: 5.0 mm × 6.4 mm body, 0.65 mm pitch, moisture sensitivity level 3 (260°C peak reflow, 168 hr floor life).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (IN–) | High-impedance differential input for each of four op-amp channels; accepts signals within extended common-mode range. |
| 2, 6, 10, 14 | Non-inverting Input (IN+) | High-impedance differential input; no phase inversion when driven beyond supply rails. |
| 3, 7, 11, 12 | Output (OUT) | Rail-to-rail output capable of sourcing/sinking ±3 mA while maintaining <1 V saturation at full load. |
| 4 | VDD+ | Positive supply connection; supports 2.7–10 V operation with internal ESD protection diodes. |
| 8 | VDD– / GND | Negative supply or ground reference; common return for all four amplifiers and bias circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range in single-supply systems: VOH ≥ 4.97 V and VOL ≤ 0.01 V at 5 V supply and light load. |
| No phase inversion | Prevents catastrophic output latch-up during input overdrive - eliminates need for external clamping in safety-critical brake system interfaces. |
| Low input offset voltage (A-grade) | Guaranteed ≤950 μV max at 25°C and ≤2000 μV over full –40°C to 125°C range - reduces calibration burden in battery cell voltage monitoring. |
| Ultra-low input bias current | 1 pA typical enables use with >100 MΩ source impedances (e.g., thermistors, pH electrodes) without significant offset error. |
| Automotive qualification | AEC-Q100 Grade 1 qualified (–40°C to 125°C), with production flow traceability and PPAP support for OEM Tier-1 suppliers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434AQDRQ1 | Same electrical specs but in SOIC-14 (4.9 mm × 6.0 mm); higher MSL-1 rating (unlimited floor life). | Preferred for through-hole prototyping or legacy board designs with SOIC footprints. | Select when PCB layout uses SOIC-14 and reflow profile supports Level-1 handling. |
| LMV324QDRQ1 | Higher VIO (3 mV max), lower drive (±20 mA), wider supply (2.7–5.5 V), no guaranteed A-grade offset spec. | Suitable for cost-sensitive non-precision functions like power supply monitoring or LED dimming control. | Choose only if offset and drift requirements are relaxed; not recommended for BMS or brake system signal chains. |
Compared with TLV2434AQDRQ1, TLV2434AQPWRQ1 offers identical performance in a smaller TSSOP-14 footprint ideal for space-constrained ADAS modules, while LMV324QDRQ1 trades precision for lower cost and higher output current - making it unsuitable for applications demanding sub-millivolt DC accuracy.

FAQ
What is the maximum operating temperature range for TLV2434AQPWRQ1?
The TLV2434AQPWRQ1 is rated for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. This range is validated across all electrical parameters including input offset voltage, supply current, and output drive capability - ensuring reliable performance in engine bay and under-hood automotive environments where thermal stress is extreme.
Does TLV2434AQPWRQ1 support true rail-to-rail input operation?
No, TLV2434AQPWRQ1 provides rail-to-rail *output* swing but has an extended common-mode input voltage range (0 V to VDD+ – 0.5 V), not full rail-to-rail input. It does not accept inputs at or beyond the positive rail. However, its lack of phase inversion when overdriven makes it more robust than standard CMOS op-amps in applications where input signals may transiently exceed the common-mode limits.
What is the guaranteed input offset voltage specification for TLV2434AQPWRQ1?
The TLV2434AQPWRQ1 is the 'A' grade variant, guaranteeing a maximum input offset voltage of 950 μV at TA = 25°C and 2000 μV over the full –40°C to +125°C temperature range. This specification is tested and binned during production, distinguishing it from the standard TLV2434QDRQ1 (2.5 mV max at 25°C) and enabling high-accuracy DC measurements without trimming.
Can TLV2434AQPWRQ1 drive a 600 Ω load while maintaining rail-to-rail output swing?
Yes, TLV2434AQPWRQ1 is specified to deliver ±3 mA output current into 600 Ω loads while maintaining rail-to-rail output swing: at 5 V supply, VOH ≥ 4.35 V and VOL ≤ 0.8 V at ±3 mA. This capability allows direct interface to ADC reference buffers, analog multiplexers, or other op-amp inputs without additional gain stages - reducing component count and board area in compact automotive modules.
Is TLV2434AQPWRQ1 pin-compatible with other devices in the TLV243x family?
TLV2434AQPWRQ1 shares identical pinout with TLV2434AQDRQ1 (SOIC-14) and TLV2434QPWRQ1 (TSSOP-14, non-A grade), enabling drop-in replacement between TSSOP and SOIC packages for the same channel count. However, it is not pin-compatible with dual-channel variants (e.g., TLV2432AQPWRQ1) due to different pin assignments and channel count - PCB layout must match the 14-pin quad configuration.
