Product details
Overview
TLV2432CPWLE from Texas Instruments is a dual, rail-to-rail output, low-voltage operational amplifier featuring 125 µA per channel max supply current, 18 nV/√Hz typical input voltage noise at 1 kHz, and extended common-mode input range (0 V to 4.5 V min with 5-V supply). It delivers rail-to-rail output swing, no phase inversion, and 600-Ω load drive capability - ideal for precision signal conditioning in battery-powered sensor interfaces.
For engineers reviewing the TLV2432CPWLE datasheet, TLV2432CPWLE pinout, TLV2432CPWLE application, or TLV2432CPWLE equivalent, key selection considerations include its 950 µV max input offset voltage (TLV2432A variant), 0.55 MHz gain-bandwidth product at 5 V, ±1.5 V to ±5 V dual-supply compatibility, and TSSOP-8 package thermal performance for space-constrained analog front-ends.
Technical Context
The TLV2432CPWLE employs Advanced LinCMOS™ process technology to achieve ultra-low input bias current (1 pA typ) and high input impedance (>1000 GΩ), enabling accurate amplification of high-impedance sources like piezoelectric transducers. Its rail-to-rail output stage supports full dynamic range utilization across single-supply (2.7–10 V) and split-supply configurations.
It avoids phase inversion when common-mode input reaches either supply rail - a critical advantage over standard CMOS op-amps - and maintains stable operation with 62° phase margin at unity gain into 2-kΩ/100-pF loads. The device is fully characterized at 3-V and 5-V supplies for low-voltage system integration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply portable systems and industrial 5-V rails without level-shifting. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables DC-coupled precision gain stages with sub-mV error budgets. |
| Supply Current (per channel) | 125 µA max - allows continuous operation in multi-channel, coin-cell–powered monitoring nodes. |
| Input Voltage Noise | 18 nV/√Hz at f = 1 kHz - preserves SNR in low-level sensor signal chains (e.g., thermopiles, strain gauges). |
| Output Drive Capability | 600-Ω load at VOH/VOL extremes - ensures robust interfacing to ADC reference buffers and active filters. |
| Common-Mode Input Range | 0 V to 4.5 V (min) with 5-V supply - accommodates ground-referenced sensors without input biasing networks. |
| Gain-Bandwidth Product | 0.55 MHz at VDD = 5 V - sufficient for anti-aliasing filters, medical ECG preamps, and slow-control loop compensation. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad optional, RoHS-compliant, rated for 0°C to 70°C operation (C-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Rail-to-rail capable; drives 600-Ω loads to within 20 mV of rails at 5 mA. |
| 2 (IN1–) | Channel 1 inverting input | High-impedance node (1000 GΩ); accepts signals down to VDD– without phase inversion. |
| 3 (IN1+) | Channel 1 non-inverting input | Same common-mode range as IN1–; supports DC-coupled sensor inputs referenced to ground. |
| 4 (VDD– / GND) | Negative supply / ground | Single-supply reference point; must be low-impedance for noise-sensitive applications. |
| 5 (IN2+) | Channel 2 non-inverting input | Independent high-Z input; usable for differential sensing or independent signal paths. |
| 6 (IN2–) | Channel 2 inverting input | Matches IN1– specs; enables dual-channel instrumentation amplifier configurations. |
| 7 (OUT2) | Channel 2 output | Functionally identical to OUT1; supports dual-sensor readout or signal redundancy. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; internal regulation not required; bypass capacitor recommended at pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives to within 20 mV of VDD+ and VDD– at 5 mA - maximizes ADC input range and dynamic headroom. |
| No phase inversion | Operates linearly even when common-mode input reaches supply rails - eliminates need for input clamping diodes. |
| Ultra-low input bias current | 1 pA typical - prevents signal degradation in high-Z pH electrodes, photodiode transimpedance stages, and capacitive sensors. |
| Low-noise, low-power architecture | 18 nV/√Hz noise + 125 µA/channel - achieves 10-bit ENOB at 1 kSPS in energy-constrained wireless sensor nodes. |
| Extended common-mode input range | 0 V to 4.5 V (min) on 5-V supply - simplifies design of single-supply transducer interfaces without external biasing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MCP6022-I/SN | Higher supply current (160 µA/channel), lower offset (250 µV max), 10 MHz GBW - trades power for speed and precision. | Better suited for higher-bandwidth sensor interfaces (e.g., ultrasonic flow meters) but increases quiescent power. | Select MCP6022-I/SN when >1 MHz bandwidth or <500 µV VIO is required; verify thermal dissipation in TSSOP-8 layout. |
| OPA2333AIDR | Zero-drift architecture, 2 µV max VIO, 0.17 µV/°C drift, 35 µA/channel - superior DC accuracy and temperature stability. | Ideal for long-duration DC measurements (e.g., environmental loggers) where offset drift dominates error budget. | Choose OPA2333AIDR for sub-µV drift-critical applications; note higher cost and reduced output drive (25 mA vs 50 mA). |
Compared with MCP6022-I/SN and OPA2333AIDR, TLV2432CPWLE offers optimal balance of micropower operation, rail-to-rail output, and cost-effective precision for general-purpose analog front-ends - especially where 0.55 MHz bandwidth and 950 µV offset meet system requirements without over-engineering.

FAQ
What is the maximum operating supply voltage for TLV2432CPWLE?
The absolute maximum supply voltage for TLV2432CPWLE is 12 V, but the recommended operating range is 2.7 V to 10 V. Operation above 10 V risks exceeding safe dissipation limits in the TSSOP-8 package, particularly at elevated ambient temperatures. Always observe derating curves in the datasheet's Dissipation Rating Table for sustained operation.
Does TLV2432CPWLE support true rail-to-rail input?
No - TLV2432CPWLE features rail-to-rail *output* only. Its common-mode input voltage range extends to 0 V (VDD–) and up to VDD+ – 1.3 V (e.g., 3.7 V on 5-V supply), which exceeds typical CMOS op-amps but does not reach the positive rail. This "wide-input-voltage" architecture avoids phase inversion without requiring full rail-to-rail input circuitry.
Can TLV2432CPWLE drive a 1000-pF capacitive load directly?
TLV2432CPWLE is stable with 100-pF capacitive loads at unity gain (62° phase margin), but driving 1000-pF loads requires external isolation resistance (e.g., 100 Ω in series with output) to maintain stability. Uncompensated 1000-pF loading causes peaking and potential oscillation due to increased phase lag in the feedback loop.
What is the guaranteed input offset voltage specification for TLV2432CPWLE?
TLV2432CPWLE is the standard-grade version with 2.5 mV max input offset voltage at TA = 25°C. For tighter offset, select TLV2432AIPW (950 µV max at 25°C, –40°C to 85°C range). The 'A' suffix denotes enhanced precision binning - TLV2432CPWLE itself is not specified below 2.5 mV.
Is TLV2432CPWLE qualified for automotive applications?
No - TLV2432CPWLE carries the 'C' temperature suffix (0°C to 70°C), intended for commercial applications. Automotive-grade variants exist (e.g., TLV2432AQD, TLV2432AIPW with Q/I suffixes), but TLV2432CPWLE is not AEC-Q100 qualified and lacks automotive-specific screening or documentation.
