Product details
Overview
TLV2432AIPWR 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 (TA = 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 TLV2432AIPWR datasheet, TLV2432AIPWR pinout, TLV2432AIPWR application, or TLV2432AIPWR equivalent, key selection criteria include rail-to-rail output swing (0 V to VDD–0.25 V), extended common-mode input range (0 V to 4.5 V at 5 V supply), no phase inversion, and TSSOP-8 packaging for space-constrained analog front-ends.
Technical Context
The TLV2432AIPWR uses CMOS input stage architecture with Class AB output stage, supporting true rail-to-rail output swing without phase reversal when inputs reach supply rails. Its high input impedance (>1 TΩ) and ultra-low input bias current (1 pA typ) preserve signal integrity from high-impedance sources like piezoelectric sensors.
It operates across 2.7 V to 10 V supply range with guaranteed performance at 3 V and 5 V, featuring 0.25 V/µs slew rate, 0.55 MHz gain-bandwidth product, and 63–90 dB CMRR - making it suitable for single-supply instrumentation where dynamic range and DC accuracy are critical.
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 TA = 25°C - enables accurate DC-coupled amplification in precision sensor signal chains. |
| Input Bias Current (typ) | 1 pA - minimizes voltage error across high-impedance source impedances (>1 MΩ). |
| Supply Current per Channel | 125 µA max - extends battery life in portable medical monitors and IoT endpoint nodes. |
| Output Swing | Rail-to-rail (0 V to VDD–0.25 V at 5 V) - maximizes ADC input dynamic range without external biasing. |
| Input Voltage Noise | 18 nV/√Hz at f = 1 kHz - preserves SNR in low-frequency sensor amplification (e.g., thermopiles, strain gauges). |
| Common-Mode Input Range | 0 V to 4.5 V (min) at 5 V supply - allows direct sensing of ground-referenced signals without attenuation. |
Pinout & Package
Packaged in an 8-pin TSSOP (PW), the TLV2432AIPWR features a compact 3 mm × 4.4 mm footprint with 0.65 mm pitch, optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Amplifier A output | Delivers rail-to-rail buffered signal; drives 600 Ω loads directly for telecom interface compliance. |
| 2 (–IN A) | Inverting input A | High-impedance CMOS node; accepts signals down to VDD– (0 V) with no phase inversion. |
| 3 (+IN A) | Non-inverting input A | Supports common-mode input to VDD–0.25 V; enables ground-sensing configurations. |
| 4 (V–) | Negative supply / GND | Reference for single-supply operation; tied to system ground in 3 V/5 V applications. |
| 5 (+IN B) | Non-inverting input B | Independent high-Z input for dual-channel signal paths (e.g., differential pair pre-amplification). |
| 6 (–IN B) | Inverting input B | Matches Pin 2 electrical behavior; supports matched gain-setting resistor networks. |
| 7 (OUT B) | Amplifier B output | Functionally identical to Pin 1; enables dual-path signal processing without cross-talk. |
| 8 (V+) | Positive supply | Accepts 2.7–10 V; internal regulation ensures stable biasing across full operating temperature range (–40°C to +85°C). |
Key Features

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 |
|---|---|---|---|
| TLV2432IPWR | Higher 2000 µV max input offset voltage (vs. 950 µV); same package, pinout, and supply specs. | Suitable for non-precision applications (e.g., general-purpose buffering) where offset calibration is impractical. | Select TLV2432IPWR only if VIO > 950 µV is acceptable and cost sensitivity outweighs DC accuracy needs. |
| MCP6022-E/SN | Higher 150 µA typical supply current; 2.7 V min supply; 10 µV max VIO but limited 2.5 V max rail-to-rail output swing at 3 V. | Better DC precision but reduced output headroom in low-voltage systems - requires careful supply margining. | Choose MCP6022-E/SN only when sub-10 µV offset is mandatory and system VDD ≥ 3.3 V ensures adequate output swing. |
Compared with TLV2432IPWR, the TLV2432AIPWR provides tighter DC accuracy for sensor front-ends; compared with MCP6022-E/SN, it delivers superior rail-to-rail output drive at 3 V while consuming less quiescent current - making it optimal for space- and power-constrained analog signal chains.

FAQ
What is the maximum operating temperature range for the TLV2432AIPWR?
The TLV2432AIPWR is rated for operation from –40°C to +85°C, matching the I-suffix specification defined in the official Texas Instruments datasheet (SLOS168G). This range is validated across all electrical parameters including input offset voltage, common-mode input range, and supply current - ensuring reliable performance in industrial and automotive cabin environments.
Does the TLV2432AIPWR support true rail-to-rail input?
No, the TLV2432AIPWR does not support rail-to-rail input; it features rail-to-rail *output* only. Its common-mode input voltage range extends from VDD– (0 V) to VDD–1.3 V (e.g., 0 V to 3.7 V at 5 V supply), which exceeds standard CMOS op-amps but does not reach the positive rail. This is explicitly documented in Section 4.3 (Recommended Operating Conditions) of the TLV2432AIPWR datasheet.
Can the TLV2432AIPWR drive a 600 Ω load effectively?
Yes, the TLV2432AIPWR is specified to drive 600 Ω loads, as confirmed in the "Features" section and electrical characteristics tables (e.g., VOH/VOL test conditions at ±3 mA). At 5 V supply, it maintains 2.5 V high-level output and 0.8 V low-level output into 600 Ω - meeting telecom line-driver requirements without external buffers.
How does the TLV2432AIPWR differ from the TLV2432AIDR?
The TLV2432AIPWR and TLV2432AIDR share identical electrical specifications and functionality, differing only in package: TLV2432AIPWR uses 8-pin TSSOP (PW), while TLV2432AIDR uses 8-pin SOIC (D). Both are I-suffix (–40°C to +85°C) and A-grade (950 µV max VIO), with identical pinouts and thermal dissipation ratings (525 mW for PW vs. 725 mW for D).
Is the TLV2432AIPWR suitable for driving SAR ADC inputs directly?
Yes, the TLV2432AIPWR is well-suited for driving SAR ADC inputs due to its rail-to-rail output swing, low output impedance (130 Ω closed-loop), and fast settling time (6.4 µs to 0.1%). Its 0.25 V/µs slew rate and 0.55 MHz GBW ensure stable acquisition within typical 1 MSPS ADC aperture times, especially when paired with 12-bit or lower-resolution converters.
