Product details
Overview
TLV2432QD from Texas Instruments is a dual-channel, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V), low-power operation. It delivers 115–150 µA per channel supply current, 0.25 V/µs slew rate at 5 V, and 950 µV max input offset voltage (TLV2432A variant), enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2432QD datasheet, TLV2432QD pinout, TLV2432QD application, or TLV2432QD 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, and 600 Ω output drive capability-critical for telecom line drivers and automotive sensor front-ends.
Technical Context
The TLV2432QD implements a CMOS-input, Class AB output stage with rail-to-rail output swing and extended common-mode input range down to V– (ground) and up to VDD – 0.8 V. Its architecture avoids phase inversion when inputs approach supply rails-a key differentiator from standard CMOS op-amps.
It is fully characterized across –40°C to +125°C (Q-suffix automotive grade), supports single-supply operation from 2.7 V, and features 1000 GΩ differential and common-mode input resistance with only 18 nV/√Hz input voltage noise at 1 kHz-enabling high-fidelity amplification of microvolt-level signals from piezoelectric or resistive sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - enables direct use with Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Input Offset Voltage (max) | 950 µV at 25°C (TLV2432A-Q1) - ensures ≤1 LSB error when driving 12-bit ADCs with 3 V full-scale range. |
| Supply Current per Channel | 150 µA max - allows >2-year battery life in continuous-monitoring IoT nodes powered by CR2032 cells. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs, maximizing SNR without external biasing. |
| Common-Mode Input Range | 0 V to 4.5 V (min) on 5 V supply - accepts ground-referenced sensor outputs without attenuation or level shift. |
| Slew Rate | 0.25 V/µs at 5 V - supports stable closed-loop gain ≥10 for bandwidths up to ~20 kHz in active filters. |
| Input Bias Current | 1 pA typ - preserves signal integrity in high-impedance pH, photodiode, or strain gauge circuits. |
Pinout & Package
TLV2432QD 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 (OUT A) | Channel A output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±3 mA into 600 Ω loads. |
| 2 (IN– A) | Channel A inverting input | High-impedance CMOS node (1000 GΩ); requires guarded trace routing in sensitive analog layouts. |
| 3 (IN+ A) | Channel A non-inverting input | Same impedance as IN–; supports common-mode voltages from V– to VDD – 0.8 V. |
| 4 (V–) | Negative supply / ground | Reference for both channels; must be low-impedance to minimize PSRR degradation. |
| 5 (IN+ B) | Channel B non-inverting input | Independent high-Z input; shares V– and V+ with Channel A but not internally coupled. |
| 6 (IN– B) | Channel B inverting input | Matches IN– A electrical characteristics; suitable for matched dual-sensor differential pairs. |
| 7 (OUT B) | Channel B output | Functionally identical to OUT A; supports independent gain/feedback networks per channel. |
| 8 (V+) | Positive supply | Accepts 2.7–10 V; internal regulation ensures consistent biasing across supply range. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion at rail inputs | Enables reliable operation in comparator-like configurations or near-rail sensor buffering without latch-up risk. |
| Rail-to-rail output swing | Maximizes usable ADC input range in single-supply systems, improving effective resolution by up to 1.5 bits. |
| 18 nV/√Hz input voltage noise | Preserves SNR in low-level signal chains (e.g., thermocouple amplifiers) where noise dominates quantization error. |
| 1 pA typical input bias current | Eliminates significant DC error in >1 MΩ source impedances-critical for electrochemical and capacitive sensing. |
| Automotive-grade temperature range | Specified from –40°C to +125°C, meeting AEC-Q100 stress test requirements for under-hood applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2432IDR | Same dual-channel architecture and pinout, but industrial-grade (–40°C to +85°C), not automotive qualified. | Lacks AEC-Q100 qualification; unsuitable for under-hood or safety-critical automotive use. | Select TLV2432IDR only for cost-sensitive industrial or consumer designs where extended temperature is not required. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2432QD's 2 µV/°C; higher 35 µA supply current per channel. | Better DC precision over temperature; less suitable for ultra-low-power or wide-bandwidth applications. | Choose OPA2333AIDR when long-term offset stability dominates over quiescent current or bandwidth requirements. |
Compared with TLV2432IDR, TLV2432QD adds automotive qualification and wider temperature support but trades off slightly higher supply current; versus OPA2333AIDR, it offers lower power and higher bandwidth at the expense of initial offset and drift performance.

FAQ
What is the maximum operating temperature range for TLV2432QD?
The TLV2432QD is rated for operation from –40°C to +125°C, meeting AEC-Q100 Grade 1 requirements for automotive applications. This specification is validated per Section 4.3 and 4.6–4.11 of the SLOS168G datasheet, with all electrical parameters guaranteed across this full range.
Does TLV2432QD support true rail-to-rail input operation?
No, TLV2432QD provides rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from V– to VDD – 0.8 V (e.g., 0 V to 4.2 V on 5 V supply), as specified in Section 4.3 of the datasheet. For true rail-to-rail input, consider TI's TLV27x or OPA333 families.
Can TLV2432QD drive a 600 Ω load effectively?
Yes, TLV2432QD is explicitly characterized to drive 600 Ω loads, delivering ±3 mA output current while maintaining rail-to-rail swing-confirmed in the "600Ω output drive" feature list and Section 4.4 (VOL/VOH tests at 3 mA). This makes it suitable for telecom line driver and legacy DAC output buffer roles.
What is the typical input offset voltage for TLV2432QD at 25°C?
The typical input offset voltage for TLV2432QD at 25°C is 300 µV, with a maximum of 950 µV for the 'A' variant (TLV2432AQD). This value is specified in Sections 4.6 and 4.10 of the SLOS168G datasheet under VIO test conditions with VDD = 3 V or 5 V and RS = 50 Ω.
Is TLV2432QD pin-compatible with other devices in the TLV243x family?
Yes, TLV2432QD shares identical 8-pin SOIC (D package) pinout with TLV2432IDR, TLV2432CDR, TLV2432AQD, and TLV2432AIDR-verified in Figure 3-1 of the datasheet. All variants maintain consistent pin functions across suffixes (C/I/Q) and performance grades (standard/A).
