Product details
Overview
TLV2432AQD from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V), low-power operation. It delivers 18 nV/√Hz input voltage noise at 1 kHz, 950 µV max input offset voltage (A-grade), and 125 µA per channel supply current - enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2432AQD datasheet, TLV2432AQD pinout, TLV2432AQD application, or TLV2432AQD 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 automotive-qualified Q-suffix temperature range (–40°C to +125°C).
Technical Context
The TLV2432AQD implements a CMOS-input, Class AB output stage architecture that enables true rail-to-rail output swing while maintaining stable operation across the full common-mode input range - including down to the negative rail. Its input stage avoids phase inversion when driven to either supply, eliminating a critical failure mode in high-gain sensor front-ends.
It is fully characterized for both 3 V and 5 V operation, with guaranteed performance over –40°C to +125°C. The A-grade variant specifies ≤950 µV input offset voltage at 25°C and ≤2000 µV over full temperature range, supporting precision DC-coupled applications without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation in 3.3 V and 5 V systems, plus extended headroom for industrial 9 V rails |
| Input Offset Voltage (max) | 950 µV at 25°C (A-grade) - enables <1 LSB error in 12-bit ADC interfaces with gain ≤10 |
| Supply Current / Channel | 150 µA max - allows >10-year battery life in always-on IoT sensor nodes using coin cells |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-frequency transducer amplification (e.g., piezoelectric, strain gauge) |
| Common-Mode Input Range | 0 V to 4.5 V (min) on 5 V supply - accepts ground-referenced signals without level-shifting circuitry |
| Output Drive Capability | 600 Ω load - directly drives SAR ADC reference buffers and analog multiplexers without external buffers |
| Gain-Bandwidth Product | 0.55 MHz - sufficient for anti-aliasing filters up to ~50 kHz and closed-loop gains ≤100 |
Pinout & Package
TLV2432AQD is housed in an 8-pin SOIC (D package), 3.9 mm × 4.9 mm body, 1.75 mm height, with standard JEDEC MS-012AC footprint and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance CMOS node (1 TΩ typical) for feedback network connection in inverting configurations |
| 2 | Non-Inverting Input (A) | Accepts DC-coupled sensor signals down to ground; no phase inversion up to VDD–0.8 V |
| 3 | Output (A) | Rail-to-rail capable (within 10 mV of rails at light load); drives 600 Ω with <1% THD+N |
| 4 | V– (GND) | Ground reference for single-supply operation; must be low-impedance for noise immunity |
| 5 | Non-Inverting Input (B) | Independent input for second channel; identical specs and rail tolerance as Pin 2 |
| 6 | Inverting Input (B) | Supports dual-channel instrumentation or differential-to-single-ended conversion |
| 7 | Output (B) | Matches Pin 3 performance; enables dual-path signal processing without cross-talk |
| 8 | V+ | Positive supply rail (2.7 V to 10 V); decoupling capacitor required within 1 cm for stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range into ADCs: VOH ≥ 4.97 V and VOL ≤ 0.01 V on 5 V supply at light load |
| No phase inversion | Stable closed-loop gain maintained even when common-mode input reaches V– or V+, preventing latch-up in high-gain sensors |
| Low input bias current | 1 pA typical - minimizes voltage error in high-Z source applications (e.g., pH electrodes, photodiodes) |
| Automotive qualification | Q-suffix certified per AEC-Q100 Grade 1 - validated for under-hood and ADAS subsystems requiring –40°C to +125°C operation |
| Low-noise design | 18 nV/√Hz at 1 kHz and 100 nV/√Hz at 10 Hz - suitable for precision DC and low-frequency AC signal chains |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432QDR | Same die, 8-pin TSSOP (PW) package; 3.0 mm × 4.4 mm, thinner profile | Better suited for space-constrained PCBs; thermal resistance higher than SOIC | Select for high-density layouts where SOIC footprint is unavailable |
| LMV358QDR | Higher supply current (150 µA vs 125 µA typ), wider offset range (3.5 mV max), no A-grade option | Lower precision; acceptable for non-critical signal paths where cost is primary constraint | Choose only if VIO > 1 mV and noise > 30 nV/√Hz are tolerable |
Compared with TLV2432AQD, TLV2432QDR offers identical electrical performance in a smaller package but requires layout rework, while LMV358QDR trades precision and noise performance for lower unit cost in non-automotive applications.

FAQ
What is the maximum operating temperature range for TLV2432AQD?
The TLV2432AQD is qualified for operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive applications. This rating is confirmed in Sections 4.6 and 4.10 of the official datasheet, where all electrical characteristics are specified across this full range - including input offset voltage (≤2000 µV), supply current (≤175 µA), and output voltage swing.
Does TLV2432AQD support true rail-to-rail input operation?
No, TLV2432AQD features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from V– to (V+ – 1.3 V) - e.g., 0 V to 3.7 V on a 5 V supply. This is explicitly defined in Section 4.3 (Recommended Operating Conditions) and verified in Tables 4.4–4.11, where VICR min/max values are consistently bounded away from V+.
Can TLV2432AQD drive a 10 kΩ load with rail-to-rail output?
Yes, TLV2432AQD maintains rail-to-rail output swing into 10 kΩ loads. Per Section 4.8 (VDD = 5 V), VOH ≥ 4.97 V and VOL ≤ 0.01 V are guaranteed at IOH/IOL = ±100 µA - well within 10 kΩ capability (±0.5 mA at 5 V). Driving heavier loads (e.g., 600 Ω) is also supported, as confirmed by the "600Ω output drive" feature statement and VOH/VOL specs at ±5 mA.
Is TLV2432AQD pin-compatible with TLV2432CDR?
Yes, TLV2432AQD and TLV2432CDR share identical 8-pin SOIC (D) package footprints and pinouts. Both follow the standard dual-op-amp configuration (Pin 1: In–A, Pin 2: In+A, Pin 3: OutA, Pin 4: GND, Pin 5: In+B, Pin 6: In–B, Pin 7: OutB, Pin 8: V+). This compatibility is confirmed in the "Device Information" table and Figures 3-1 (D package) of the datasheet.
What is the typical input bias current of TLV2432AQD at 25°C?
The typical input bias current of TLV2432AQD is 1 pA at 25°C, as stated in Section 1 (Features) and verified in Tables 4.4–4.11 under IIB test conditions. This value holds across all supply voltages (3 V and 5 V) and is consistent between C/I/Q suffixes - reflecting the CMOS input stage design inherent to the TLV243x family.
