Product details
Overview
TLV2432QDRG4Q1 from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for automotive applications (AEC-Q100 Grade 1). It delivers 18 nV/√Hz input voltage noise at 1 kHz, 950 µV max input offset voltage (TLV2432A-Q1 variant), and 125 µA per channel supply current - enabling precision signal conditioning in battery-powered vehicle subsystems such as cabin sensors and body control modules.
For engineers reviewing the TLV2432QDRG4Q1 datasheet, TLV2432QDRG4Q1 pinout, TLV2432QDRG4Q1 application, or TLV2432QDRG4Q1 equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V on 5 V supply), no phase inversion behavior near rails, 600 Ω output drive capability, and guaranteed operation from –40°C to +125°C.
Technical Context
The TLV2432QDRG4Q1 implements a CMOS-input, Class AB output stage with rail-to-rail swing and extended common-mode input range down to V– and up to VDD–1.3 V. Its architecture avoids phase inversion when inputs approach supply rails - a critical advantage over standard CMOS op-amps in sensor front-end designs.
It operates across 2.7 V to 10 V supply range, supports single- or split-supply configurations, and maintains stable unity-gain performance with 62° phase margin into 2 kΩ//100 pF loads - making it suitable for driving ADC inputs and low-power analog filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct use with 3.3 V and 5 V automotive domains and compatibility with wide-input DC-DC outputs. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures ≤1 LSB error in 12-bit ADC interfaces with 2.5 V reference. |
| Supply Current (per channel) | 150 µA max - supports >10-year battery life in always-on vehicle monitoring nodes. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in high-impedance piezoelectric or thermistor signal chains. |
| Common-Mode Input Range | 0 V to 4.5 V (min) on 5 V supply - allows direct interfacing with 0–5 V sensor outputs without level-shifting. |
| Output Drive Capability | 600 Ω load - sufficient to drive SAR ADC input networks and RC anti-aliasing filters without buffer stages. |
| Operating Temperature | –40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood and cabin electronics. |
Pinout & Package
TLV2432QDRG4Q1 is housed in an 8-pin SOIC (D package), 3.9 mm × 4.9 mm body, with 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | High-impedance node (1 TΩ) for feedback network connection; sensitive to PCB leakage and guarding. |
| 2 | Non-Inverting Input (Channel A) | Accepts sensor signals directly; common-mode range extends to both rails for single-supply sensor interfacing. |
| 3 | Output (Channel A) | Rail-to-rail swing (0.01 V to 4.97 V on 5 V) drives ADC inputs or low-power transducers. |
| 4 | V– (Ground) | Reference return for both channels; must be low-impedance and separated from digital ground in mixed-signal layouts. |
| 5 | Non-Inverting Input (Channel B) | Independent input for dual-path sensing (e.g., differential temperature or pressure). |
| 6 | Inverting Input (Channel B) | Supports independent gain-setting resistors per channel; no crosstalk between amplifiers. |
| 7 | Output (Channel B) | Matches Channel A performance; enables simultaneous dual-sensor readout without multiplexing delay. |
| 8 | V+ | Positive supply rail; decoupling capacitor (100 nF X7R) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion at rail inputs | Eliminates output glitches during sensor signal saturation - critical for fault-tolerant automotive diagnostics. |
| Rail-to-rail output swing | Maximizes dynamic range into 12-bit+ ADCs, increasing effective resolution by ≥1 bit vs. non-rail-to-rail op-amps. |
| Low 1-pA typical input bias current | Prevents significant voltage drop across >1 MΩ sensor sources (e.g., pH electrodes, pyroelectric detectors). |
| 18 nV/√Hz input voltage noise | Enables sub-millivolt signal detection in low-frequency (<10 kHz) automotive sensor applications. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation at +125°C ambient - meets requirements for engine bay, HVAC, and lighting control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IQ2T | Higher GBW (8 MHz vs. 0.55 MHz), lower VIO (1.5 mV typ), but higher supply current (880 µA/ch) and no AEC-Q100 qualification. | Not suitable for automotive safety-critical or long-life battery systems; better for high-speed industrial signal chains. | Select only if bandwidth >1 MHz is required and automotive qualification is unnecessary. |
| LMV932QDRQ1 | Similar AEC-Q100 Grade 1 rating and 125 µA supply current, but higher VIO (3.5 mV max) and no guaranteed rail-to-rail input. | Acceptable for cost-sensitive non-precision automotive functions (e.g., fan speed control), but not for sensor front-ends requiring <1 mV offset. | Choose when budget constraints outweigh precision requirements and rail-to-rail input is not needed. |
Compared with TSV912IQ2T and LMV932QDRQ1, TLV2432QDRG4Q1 uniquely balances ultra-low power (125 µA), precision offset (950 µV max), rail-to-rail output, and full automotive qualification - making it optimal for battery-constrained, high-accuracy vehicle sensor nodes where longevity and reliability are mandatory.

FAQ
What is the maximum operating temperature range for TLV2432QDRG4Q1?
The TLV2432QDRG4Q1 is rated for continuous operation from –40°C to +125°C ambient temperature and is qualified per AEC-Q100 Grade 1. This specification is verified across all electrical parameters in the official TI datasheet (SLOS168G, Section 4.3 and 4.6–4.11), ensuring reliable performance in under-hood and cabin environments where thermal stress is critical. TLV2432QDRG4Q1 maintains specified offset, noise, and drive capability across this full range.
Does TLV2432QDRG4Q1 support true rail-to-rail input operation?
No, TLV2432QDRG4Q1 features rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from V– to (VDD – 1.3 V) - for example, 0 V to 3.7 V on a 5 V supply. This is explicitly defined in Sections 4.3 and 4.6–4.11 of the TI datasheet. While it accepts inputs down to ground, it does not fully reach VDD, distinguishing it from true rail-to-rail input op-amps like the TLV9002.
What is the typical input bias current of TLV2432QDRG4Q1 and why does it matter?
The TLV2432QDRG4Q1 has a typical input bias current of 1 pA, with a maximum of 60 pA over temperature (Section 4.6). This ultra-low value prevents significant voltage error across high-impedance sensor sources - such as thermistors (>100 kΩ), piezoelectric elements, or pH electrodes - ensuring accurate signal acquisition without added loading or calibration drift. TLV2432QDRG4Q1's bias current is confirmed in both 3 V and 5 V operating conditions.
Can TLV2432QDRG4Q1 drive a 2 kΩ load while maintaining rail-to-rail output?
Yes, TLV2432QDRG4Q1 guarantees rail-to-rail output swing into 2 kΩ loads: at 5 V supply, VOH ≥ 4.97 V (IOH = –100 µA) and VOL ≤ 0.01 V (IOL = 100 µA), per Section 4.10 of the datasheet. It also sustains 4 V high-level and 1.25 V low-level output into 5 mA loads - confirming robust 600 Ω drive capability. TLV2432QDRG4Q1's output stage is explicitly characterized for telecom-grade load driving in the device description.
Is TLV2432QDRG4Q1 pin-compatible with other TLV243x-Q1 variants?
Yes, TLV2432QDRG4Q1 shares identical 8-pin SOIC (D) pinout with TLV2432AQDRG4Q1 and TLV2432QDRQ1 - all follow the standard dual-op-amp configuration (IN–/IN+/OUT/V–/IN+/IN–/OUT/V+). Pin compatibility is confirmed in Figure 3-1 of the datasheet and supported by TI's packaging documentation (Section 8). No PCB redesign is required when upgrading from TLV2432QDRQ1 to TLV2432QDRG4Q1, as both are functionally identical except for tape-and-reel packaging and minor marking differences.
