Product details
Overview
TLV2432AQDG4 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 TLV2432AQDG4 datasheet, TLV2432AQDG4 pinout, TLV2432AQDG4 application, or TLV2432AQDG4 equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V @ 5 V supply), no phase inversion behavior near rails, and 600 Ω output drive capability for telecom and industrial analog front-ends.
Technical Context
The TLV2432AQDG4 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 0 V and VDD - without phase reversal. Its high-impedance inputs (1 TΩ differential and common-mode resistance) and low bias current (1 pA typ) support high-impedance source interfacing, such as piezoelectric transducers.
It operates with specified performance over –40°C to +125°C (Q-grade automotive qualification), supports single-supply configurations down to 2.7 V, and exhibits 0.25 V/µs slew rate and 0.55 MHz gain-bandwidth product at 5 V - balancing speed, precision, and ultra-low quiescent power.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct integration into 3.3 V and 5 V systems without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - ensures <1 LSB error when driving 12-bit ADCs with 3 V full-scale range. |
| Supply Current (per channel) | 150 µA max - allows >1-year battery life in coin-cell–powered IoT sensors operating at 10 µA average system current. |
| Output Drive Capability | 600 Ω load @ ±3 mA - supports direct driving of legacy telecom line interfaces and resistive DAC loads. |
| Input Voltage Noise | 18 nV/√Hz @ 1 kHz - preserves SNR in low-level sensor amplification stages (e.g., thermopiles, strain gauges). |
| Common-Mode Input Range | 0 V to VDD – 1.3 V - permits direct sensing of ground-referenced signals in single-supply systems. |
| Gain-Bandwidth Product | 0.55 MHz @ 5 V - sufficient for anti-aliasing filters and closed-loop gains ≤100 without stability compromise. |
Pinout & Package
TLV2432AQDG4 is housed in an 8-pin SOIC (D package) with standard dual op-amp pinout. The package is RoHS-compliant, surface-mountable, and rated for automotive temperature range (–40°C to +125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - rail-to-rail swing supports full dynamic range utilization with 3 V ADCs. |
| 2 | IN– A | Inverting input - high impedance (1 TΩ) minimizes loading on high-Z sources like pH electrodes. |
| 3 | IN+ A | Non-inverting input - common-mode range includes ground, enabling single-supply transducer biasing. |
| 4 | V– | Negative supply / ground reference - accepts 0 V in single-supply mode; no phase inversion at rail. |
| 5 | IN+ B | Non-inverting input (Channel B) - identical specs to Channel A; enables dual-sensor signal conditioning. |
| 6 | IN– B | Inverting input (Channel B) - matched offset and drift enable precision differential amplification. |
| 7 | OUT B | Output (Channel B) - independent rail-to-rail output supports dual-channel data acquisition. |
| 8 | V+ | Positive supply - operates down to 2.7 V, compatible with Li-ion and 3.3 V LDO outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of both supply rails at 3 mA load - maximizes ADC utilization and simplifies level-shifting. |
| No phase inversion at supply rails | Eliminates output glitches during common-mode transients - critical for motor control feedback and safety-critical monitoring. |
| Extended common-mode input range | Operates with inputs from 0 V to VDD – 1.3 V - enables direct connection to ground-referenced sensors without external bias. |
| Low input bias current (1 pA typ) | Prevents signal degradation in high-impedance circuits (e.g., photodiode amps, electret mic preamps). |
| Automotive Q-grade qualification | Specified and tested over –40°C to +125°C - meets AEC-Q100 requirements for under-hood and ADAS applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432CDR | Commercial-grade (0°C to 70°C), same electrical specs but non-automotive qualified. | Limited to consumer/portable equipment; not suitable for under-hood or safety-critical systems. | Select when cost sensitivity outweighs temperature or reliability requirements. |
| MCP6022-E/SN | Higher supply current (1 mA/ch), wider GBW (10 MHz), but higher noise (25 nV/√Hz) and no Q-grade option. | Better for high-speed filtering but less optimal for ultra-low-power precision sensing. | Choose only if bandwidth >1 MHz is required and battery life is secondary. |
Compared with TLV2432AQDG4, TLV2432CDR lacks automotive qualification and extended temperature support, while MCP6022-E/SN trades ultra-low power for higher speed and noise - making TLV2432AQDG4 the optimal choice for automotive-qualified, low-noise, long-life sensor signal chains.

FAQ
What is the maximum operating temperature range for TLV2432AQDG4?
The TLV2432AQDG4 is qualified for operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 automotive requirements. This rating is confirmed in Section 4.6 and 4.10 of the datasheet under Q-suffix specifications, where all electrical parameters are guaranteed across this full range - unlike commercial-grade variants limited to 0°C–70°C.
Does TLV2432AQDG4 support true rail-to-rail input operation?
No, TLV2432AQDG4 features rail-to-rail *output* only. Its common-mode input voltage range extends from 0 V to VDD – 1.3 V (e.g., 0 V to 3.7 V at 5 V supply), as specified in Section 4.3 and 4.8. It does not accept inputs at the positive rail, distinguishing it from rail-to-rail input/output amplifiers.
Can TLV2432AQDG4 drive a 10 kΩ load with rail-to-rail output swing?
Yes - the TLV2432AQDG4 maintains rail-to-rail output swing into 10 kΩ loads, as verified by VOH/VOL specifications in Sections 4.4–4.11 (e.g., VOH = 4.97 V @ IOH = –100 µA, VOL = 0.01 V @ IOL = 100 µA at 5 V). Its 600 Ω drive rating refers to minimum guaranteed performance at higher currents (±3 mA), not a limitation.
Is TLV2432AQDG4 pin-compatible with other dual op-amps in SOIC-8?
TLV2432AQDG4 uses the industry-standard dual op-amp pinout (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = V–, pin 5 = IN+ B, pin 6 = IN– B, pin 7 = OUT B, pin 8 = V+), matching LM358, TLV2372, and MCP6022. However, electrical behavior (e.g., rail-to-rail output, no phase inversion) differs - layout reuse is possible, but circuit validation is required.
What is the typical input offset voltage drift over temperature for TLV2432AQDG4?
The TLV2432AQDG4 has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C over 25°C to 70°C, as specified in Sections 4.4, 4.6, 4.8, and 4.10. This low drift ensures minimal calibration burden in systems operating across wide ambient ranges, especially when combined with its 950 µV max initial offset.
