Product details
Overview
TLV2432CPW from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, micropower operation. It delivers 125 µA per channel supply current, 18 nV/√Hz input voltage noise at 1 kHz, and rail-to-rail output swing (0 V to VDD–0.8 V) with extended common-mode input range (0 V to 4.5 V min at 5-V supply). It is used in battery-powered sensor signal conditioning and precision analog front-ends interfacing with ADCs.
For engineers reviewing the TLV2432CPW datasheet, TLV2432CPW pinout, TLV2432CPW application, or TLV2432CPW equivalent, key selection criteria include its 950 µV max input offset voltage (TLV2432A variant), 0.55 MHz gain-bandwidth product at 5 V, 6.4 µs settling time to 0.1%, and TSSOP-8 package compatibility with space-constrained industrial and portable designs.
Technical Context
The TLV2432CPW employs Advanced LinCMOS™ process technology to achieve high input impedance (>1000 GΩ common-mode and differential resistance), ultra-low input bias current (1 pA typ), and no phase inversion when driven to supply rails. Its internal architecture supports stable unity-gain operation with 62°–66° phase margin and 11 dB gain margin under 2-kΩ load and 100-pF capacitive loading.
It operates across 2.7 V to 10 V supply range, fully characterized at 3 V and 5 V, and maintains rail-to-rail output drive into 600-Ω loads - enabling direct interface with telecom line drivers and SAR ADC reference buffers without external level-shifting circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply operation from Li-ion (3.0–4.2 V) or dual AA (3.0 V) systems. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables <1 LSB error in 12-bit ADC systems with 2.5 V reference. |
| Supply Current (per channel) | 125 µA max - allows >1-year battery life in continuous-sensing applications using CR2032 cells. |
| Output Swing | 0 V to VDD–0.8 V (min at 5 V) - delivers full dynamic range into ADC inputs referenced to ground or VDD/2. |
| Gain-Bandwidth Product | 0.55 MHz at VDD = 5 V - sufficient for anti-aliasing filters up to ~50 kHz and sensor amplification with DC–10 kHz bandwidth. |
| Common-Mode Input Range | 0 V to 4.5 V (min, 5-V supply) - accepts signals directly from resistive sensors or DAC outputs without level shifters. |
| Input Voltage Noise | 18 nV/√Hz at f = 1 kHz - preserves SNR in low-level piezoelectric or thermopile transducer interfaces. |
Pinout & Package
TSSOP-8 (PW) package: 3.0 mm × 4.4 mm, 0.65 mm pitch, exposed pad not electrically connected, RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Channel 1 output | Delivers rail-to-rail voltage swing; capable of sourcing/sinking ±3 mA into 600-Ω load. |
| 2 (IN1–) | Channel 1 inverting input | High-impedance node (1000 GΩ); sensitive to PCB leakage and guarding requirements. |
| 3 (IN1+) | Channel 1 non-inverting input | Accepts common-mode signals from 0 V to VDD–1.3 V; no phase inversion at rail extremes. |
| 4 (GND / VDD–) | Negative supply / ground reference | Single-supply operation uses this as system ground; split-supply use requires connection to –VDD. |
| 5 (IN2+) | Channel 2 non-inverting input | Independent high-Z input; matches IN1+ performance and common-mode range. |
| 6 (IN2–) | Channel 2 inverting input | Matches IN1– specs; supports differential configurations with matched layout. |
| 7 (OUT2) | Channel 2 output | Electrically identical to OUT1; enables dual-path signal processing or dual feedback loops. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Common-mode input extends to both supply rails without output polarity reversal - eliminates need for input clamping diodes in rail-sensing circuits. |
| Rail-to-rail output | Drives from 0 V to VDD–0.8 V (min) - maximizes usable ADC input range and improves system SNR by 3–6 dB vs limited-swing op-amps. |
| Ultra-low input bias current | 1 pA typical - prevents significant voltage error across high-impedance sources (>10 MΩ), e.g., pH electrodes or photodiode transimpedance stages. |
| Low-noise micropower design | 18 nV/√Hz noise + 125 µA supply current - achieves best-in-class noise-power tradeoff for always-on environmental monitors. |
| Extended common-mode range | 0 V to 4.5 V (min, 5-V supply) - accommodates direct connection to unbuffered DAC outputs or resistive divider networks without level-shifting. |

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 |
|---|---|---|---|
| TLV2432AIPW | Same pinout and package; tighter 950 µV max input offset voltage (vs 2.5 mV for TLV2432CPW) over –40°C to 85°C range. | Required for industrial temperature range operation where offset drift must be minimized across thermal cycling. | Select TLV2432AIPW when operating above 70°C ambient or requiring guaranteed offset spec over full industrial range. |
| MCP6022-E/SN | Higher 170 µA/channel supply current; 14 nV/√Hz noise; 10 MHz GBW; SOIC-8 only - no TSSOP-8 option. | Better suited for higher-speed sensor interfaces (e.g., ultrasonic flow meters) but increases power budget by 36%. | Choose MCP6022-E/SN only if bandwidth >1 MHz is required and board area allows SOIC-8 footprint. |
Compared with TLV2432CPW, TLV2432AIPW offers guaranteed lower offset across wider temperature range at identical power and noise, while MCP6022-E/SN trades 36% higher supply current for 18× greater bandwidth - making TLV2432CPW optimal for ultra-low-power, DC–100 kHz precision sensing where size and battery life are critical.

FAQ
What is the maximum operating temperature range for TLV2432CPW?
The TLV2432CPW is rated for 0°C to 70°C free-air operating temperature (C-suffix grade). It is not qualified for industrial (–40°C to 85°C) or automotive temperature ranges - for those, select TLV2432AIPW (I-suffix) or TLV2432AQD (Q-suffix), respectively. Thermal derating begins above 25°C per the dissipation rating table in the datasheet, limiting safe power dissipation in compact enclosures.
Does TLV2432CPW support true rail-to-rail input operation?
No, TLV2432CPW does not provide rail-to-rail input common-mode range. Its specified common-mode input voltage range is 0 V to VDD–1.3 V (e.g., 0 V to 3.7 V at 5 V supply), with minimum guaranteed range of 0 V to 4.5 V. It avoids phase inversion at rail extremes but does not accept inputs equal to VDD. For full rail-to-rail input capability, consider TI's TLV27x or OPA333 families.
Can TLV2432CPW drive a 1000-pF capacitive load stably?
TLV2432CPW is characterized for stability with ≤100 pF capacitive load and 2-kΩ series resistance. Driving 1000-pF directly may cause peaking or oscillation due to reduced phase margin. To drive heavy capacitive loads, add a 20–100 Ω isolation resistor between the output and the capacitor, or use a unity-gain buffer configuration with external compensation per Figure 48 in the datasheet.
What is the typical input offset voltage drift over temperature for TLV2432CPW?
The TLV2432CPW has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C, measured from 25°C to 70°C. Over its full 0°C to 70°C operating range, total offset drift remains within ±140 µV (70°C span × 2 µV/°C), assuming linear behavior. Long-term drift is specified at 0.003 µV/month under accelerated life testing conditions.
Is TLV2432CPW pin-compatible with other dual op-amps in TSSOP-8 packages?
TLV2432CPW follows standard TSSOP-8 pinout for dual op-amps (pin 1 = OUT1, pin 2 = IN1–, pin 3 = IN1+, pin 4 = GND, pin 5 = IN2+, pin 6 = IN2–, pin 7 = OUT2, pin 8 = VDD+), matching industry convention. However, electrical characteristics (e.g., supply current, noise, offset) differ significantly from alternatives like MCP6022 or LMV722 - functional substitution requires validation of gain, bandwidth, and DC accuracy in the target circuit.
