Product details
Overview
TLV2432AIDR 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 950 µV max input offset voltage at 25°C, 18 nV/√Hz input voltage noise at 1 kHz, and 125 µA per channel supply current - enabling precision signal conditioning in battery-powered sensor interfaces and ADC drivers.
For engineers reviewing the TLV2432AIDR datasheet, TLV2432AIDR pinout, TLV2432AIDR application, or TLV2432AIDR equivalent, key selection criteria include its extended common-mode input range (0 V to 4.5 V on 5 V supply), no phase inversion at rails, 600 Ω output drive capability, and SOIC-8 packaging compatible with industrial temperature range (–40°C to +85°C).
Technical Context
The TLV2432AIDR uses CMOS input stage architecture with Class AB output stage, supporting rail-to-rail output swing while maintaining stable operation without phase inversion when inputs reach either supply rail. Its high input impedance (>1 TΩ) and ultra-low input bias current (1 pA typ) make it suitable for high-impedance source interfacing.
It is fully characterized across 3 V and 5 V supplies, with guaranteed performance over –40°C to +85°C (I-suffix). The device exhibits 0.25 V/µs slew rate, 0.55 MHz gain-bandwidth product, and 66° phase margin at unity gain with 2 kΩ load and 100 pF capacitive load - ensuring robust stability in single-supply configurations.
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 level-shifting. |
| Input Offset Voltage (max) | 950 µV at 25°C - enables accurate DC-coupled amplification in precision sensor front-ends. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - minimizes added noise in low-level analog signal chains (e.g., thermopile, strain gauge). |
| Supply Current per Channel | 150 µA max - allows multi-channel operation in energy-constrained portable devices. |
| Common-Mode Input Range | 0 V to 4.5 V (min) on 5 V supply - accommodates ground-referenced inputs without external biasing. |
| Output Drive Capability | 600 Ω load - sufficient to directly drive SAR ADC reference buffers and telecom line interfaces. |
| Phase Margin | 66° at unity gain - ensures stable closed-loop behavior with typical capacitive loads up to 100 pF. |
Pinout & Package
TLV2432AIDR is housed in an 8-pin SOIC (D package), 3.91 mm × 4.90 mm body, 1.75 mm height, with standard JEDEC MS-012AC footprint and 1.27 mm pitch. Pin 1 marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | High-impedance node for feedback network connection; accepts signals down to V– (GND) with no phase reversal. |
| 2 | Non-Inverting Input (A) | High-Z input for signal source; supports common-mode range from V– to VDD–1.3 V. |
| 3 | Output (A) | Rail-to-rail output capable of sourcing/sinking ±3 mA into 600 Ω load while staying within 100 mV of rails. |
| 4 | V– (Ground) | Power return for dual-supply or ground reference for single-supply operation. |
| 5 | Non-Inverting Input (B) | Independent second channel input; identical electrical specs to Pin 2. |
| 6 | Inverting Input (B) | Second channel inverting input; supports same rail-to-rail input behavior as Pin 1. |
| 7 | Output (B) | Second rail-to-rail output; electrically isolated from Output A; shares VDD and V– rails. |
| 8 | VDD | Positive supply rail; operates from 2.7 V to 10 V; decoupling capacitor required near this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 100 mV of VDD and V– at ±3 mA load - maximizes dynamic range for 12-bit+ ADC interfacing. |
| No phase inversion at supply rails | Eliminates output glitches during input transients crossing V– or VDD - critical for sensor monitoring in safety-critical systems. |
| Ultra-low input bias current | 1 pA typical - preserves signal integrity when amplifying high-impedance sources like pH electrodes or piezoelectric sensors. |
| Low-noise, low-drift architecture | 18 nV/√Hz noise + 2 µV/°C offset drift - maintains accuracy over temperature in uncalibrated industrial instrumentation. |
| Optimized for 3 V / 5 V operation | Fully specified at both voltages with consistent gain-bandwidth (0.55 MHz) and CMRR (≥63 dB) - simplifies design reuse across voltage domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2314AIDR | Lower input offset (1.8 mV max), higher GBW (3 MHz), 125 µA/channel - but no guaranteed phase inversion immunity at rails. | Better for AC-coupled, higher-speed applications; unsuitable where input may reach supply rails. | Select TLV2432AIDR when rail-to-rail input tolerance and phase-inversion immunity are mandatory; OPA2314AIDR where speed dominates. |
| MCP6022-I/SN | Higher supply current (250 µA/channel), wider VDD range (2.7 V–6.0 V), 3.5 mV VIO max - lacks 600 Ω drive spec and full 5 V characterization. | Acceptable for cost-sensitive consumer designs; not recommended for telecom or precision industrial use. | Choose TLV2432AIDR for guaranteed 5 V operation, low-noise, and industrial temp grade; MCP6022-I/SN only for non-critical 3.3 V applications. |
Compared with OPA2314AIDR and MCP6022-I/SN, TLV2432AIDR uniquely combines rail-to-rail output, guaranteed no-phase-inversion behavior, 950 µV VIO max, and 600 Ω drive - making it the only option among the three qualified for precision, rail-referenced sensor front-ends in industrial and automotive environments.

FAQ
What is the maximum input common-mode voltage range for TLV2432AIDR at 5 V supply?
At VDD = 5 V, the TLV2432AIDR supports a common-mode input voltage range of 0 V to 4.5 V (minimum) at 25°C, extending to 0 V to 4.2 V across the full –40°C to +85°C operating range. This allows direct interfacing with ground-referenced sensors and eliminates need for input bias networks in single-supply configurations.
Does TLV2432AIDR exhibit phase inversion when inputs approach the supply rails?
No - TLV2432AIDR is explicitly characterized to avoid phase inversion when common-mode input voltage reaches either supply rail (V– or VDD). This behavior is guaranteed across its operating temperature range and distinguishes it from many CMOS-input op-amps that invert output when inputs exceed internal bias limits.
What load can TLV2432AIDR drive while maintaining rail-to-rail output swing?
TLV2432AIDR is specified to drive 600 Ω loads while maintaining rail-to-rail output swing - delivering VOH ≥ 4.35 V and VOL ≤ 0.8 V at 5 V supply with ±5 mA output current. This capability supports direct connection to ADC reference inputs, telecom line drivers, and other moderate-impedance analog nodes.
Is TLV2432AIDR suitable for precision DC applications requiring low offset drift?
Yes - TLV2432AIDR (A-grade) guarantees ≤950 µV input offset voltage at 25°C and exhibits only 2 µV/°C typical temperature coefficient. Its long-term drift is 0.003 µV/month, making it appropriate for uncalibrated, long-duration DC measurements in industrial and medical equipment where thermal stability is critical.
What is the minimum supply voltage for TLV2432AIDR to meet all specifications?
TLV2432AIDR operates down to 2.7 V while meeting all published electrical characteristics, including input offset voltage, CMRR, and output swing. Below 2.7 V, parameters such as gain-bandwidth and slew rate degrade progressively; operation below 2.5 V is outside specification and not recommended for production designs.
