Product details
Overview
TLV2432ID from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 18 nV/√Hz input voltage noise at 1 kHz, 950 µV max input offset voltage (TLV2432A variant), and 125 µA per channel supply current, enabling precision signal conditioning in battery-powered sensor interfaces and analog front-ends for ADCs.
For engineers reviewing the TLV2432ID datasheet, TLV2432ID pinout, TLV2432ID application, or TLV2432ID equivalent, key selection criteria include its 0 V to 4.5 V common-mode input range with 5 V supply, 600 Ω output drive capability, no phase inversion behavior, and SOIC-8 packaging suitable for space-constrained industrial and portable designs.
Technical Context
The TLV2432ID implements a CMOS-input, Class AB output stage enabling true rail-to-rail output swing while maintaining stable operation across 2.7 V to 10 V supply ranges. Its extended common-mode input range (0 V to VDD – 1.3 V) eliminates need for level-shifting in single-supply systems interfacing with grounded sensors or DACs.
Designed for micropower precision, it features 1 pA typical input bias current, 1000 GΩ differential and common-mode input resistance, and 130 Ω closed-loop output impedance - supporting high-impedance source buffering and driving moderate loads without external gain-stage compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports direct integration into 3.3 V and 5 V systems without regulation |
| Input Offset Voltage (max) | 950 µV at 25°C - enables DC-coupled amplification of mV-level sensor signals without nulling circuitry |
| Supply Current per Channel | 150 µA max - allows continuous operation in multi-channel battery-powered devices for >1 year on coin cell |
| Common-Mode Input Range | 0 V to 4.2 V (5 V supply) - accepts signals referenced to ground or rail, simplifying sensor interface design |
| Output Drive Capability | ±3 mA into 600 Ω - directly drives telecom line drivers or ADC reference buffers without external buffer |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-frequency instrumentation amplifiers and piezoelectric transducer conditioning |
| Gain-Bandwidth Product | 0.55 MHz - sufficient for anti-aliasing filters, active RC stages, and closed-loop gains up to 100 at DC–10 kHz |
Pinout & Package
TLV2432ID is housed in an 8-pin SOIC (D package) with standard dual op-amp pinout. The package meets JEDEC MS-012AC, has 1.27 mm pitch, and is compatible with automated SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output A | Amplified output of Channel A; rail-to-rail swing enables full utilization of ADC input range |
| 2 | Inverting Input A | High-impedance (1000 GΩ) node for feedback network connection; minimal loading on precision dividers |
| 3 | Non-Inverting Input A | Accepts low-level sensor signals down to 0 V; no phase inversion when driven to rails |
| 4 | V– | Ground or negative supply rail; common return for both channels and external decoupling |
| 5 | Non-Inverting Input B | Independent high-Z input for second sensor or reference path; matched specs to Channel A |
| 6 | Inverting Input B | Configurable for unity-gain buffer or differential pair; same bias current and offset as Channel A |
| 7 | Output B | Second rail-to-rail output; enables dual-path signal processing or matched gain stages |
| 8 | V+ | Positive supply rail (2.7–10 V); internal bias generation ensures stable operation across full voltage range |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of both supply rails at 3 mA load - maximizes dynamic range for 12-bit+ ADCs |
| No phase inversion | Remains linear when common-mode input reaches V– or V+ - eliminates latch-up risk in overvoltage transient conditions |
| Low input bias current (1 pA typ) | Minimizes voltage error across high-value feedback resistors (>1 MΩ), preserving gain accuracy in transimpedance amps |
| Extended common-mode range (0 V to 4.5 V @ 5 V) | Accepts unipolar sensor outputs (e.g., thermistors, RTDs) without external level shifters or dual supplies |
| Automotive-grade variant available (TLV2432IDQ) | Qualified per AEC-Q100 Grade 2 (–40°C to +105°C) - supports under-hood and infotainment system deployment |

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 |
|---|---|---|---|
| OPA2314AIDR | Lower 12 nV/√Hz noise, higher 1.8 MHz GBW, but 250 µA/channel supply current | Better for high-speed filtering; less suitable for ultra-low-power logging | Select when bandwidth >1 MHz required and power budget allows +100 µA/channel |
| MCP6022-I/SN | Higher 25 µV max offset, 170 µA/channel, no guaranteed no-phase-inversion behavior | Cost-optimized general-purpose use; not recommended for rail-driven inputs | Choose for cost-sensitive consumer applications where input common-mode stays >0.3 V from rails |
Compared with OPA2314AIDR and MCP6022-I/SN, TLV2432ID provides the lowest power consumption with verified rail-to-rail input tolerance and no phase inversion - making it optimal for battery-powered sensor nodes requiring robustness against input overdrive and long service life.

FAQ
What is the maximum operating temperature range for TLV2432ID?
The TLV2432ID is rated for operation from –40°C to +85°C, matching the I-suffix industrial temperature grade. This range is validated per TI's characterization across all electrical parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in factory automation and outdoor environmental monitoring equipment where ambient temperatures exceed commercial limits.
Does TLV2432ID support true rail-to-rail input?
No, TLV2432ID provides rail-to-rail *output* only. Its common-mode input voltage range extends to 0 V and up to VDD – 1.3 V (e.g., 0 V to 3.7 V at 5 V supply), which exceeds typical CMOS op-amps but does not reach the positive rail. The device explicitly avoids phase inversion when inputs approach either rail - a key differentiator versus standard rail-to-rail input amplifiers that may latch or distort near supply extremes.
Can TLV2432ID drive a 10 kΩ load with rail-to-rail output swing?
Yes, TLV2432ID maintains rail-to-rail output swing into 10 kΩ loads across its full operating temperature and supply range. Its 600 Ω output drive specification guarantees ≥±3 mA capability, meaning it can deliver ±30 V/V gain into 10 kΩ with <10 mV headroom at both rails - sufficient for driving ADC references, LED drivers, or high-impedance filter networks without external buffering.
How does TLV2432ID differ from TLV2432AID?
TLV2432ID uses the standard TLV2432 performance grade (2000 µV max input offset), while TLV2432AID specifies the enhanced TLV2432A variant with tighter 950 µV max offset at 25°C. Both share identical pinout, package, supply current, noise, and output drive. Choose TLV2432AID for DC-critical applications like precision weigh scales or calibrated sensor calibrators where initial offset error must be minimized.
Is TLV2432ID qualified for automotive applications?
TLV2432ID itself is not automotive-qualified, but the functionally identical TLV2432IDQ (Q-suffix) is AEC-Q100 Grade 2 qualified (–40°C to +105°C) and shares the same SOIC-8 package and electrical specs. For automotive infotainment, body control, or ADAS subsystems requiring extended temperature operation and PPAP documentation, TLV2432IDQ is the designated drop-in replacement with full automotive traceability and reliability testing.
