Product details
Overview
TLV2434CPW from Texas Instruments is a quad 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 (A-grade), and 125 µA per channel supply current at 5 V - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2434CPW datasheet, TLV2434CPW pinout, TLV2434CPW application, or TLV2434CPW equivalent, key selection criteria include its 0 V to 4.5 V common-mode input range with 5 V supply, rail-to-rail output swing, absence of phase inversion near supply rails, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2434CPW implements a CMOS-input, Class AB output stage architecture that enables true rail-to-rail output voltage swing while maintaining stable operation across the full common-mode input range - including 0 V and VDD. Its high-impedance input (1000 GΩ differential and common-mode resistance) minimizes loading on high-Z sources like piezoelectric transducers and pH electrodes.
No phase inversion occurs when the input common-mode voltage approaches either supply rail - a critical advantage over standard CMOS op-amps in single-supply configurations. The device is fully characterized at both 3 V and 5 V supplies, with guaranteed performance over 0°C to 70°C (C-suffix) and specified slew rate (0.15–0.25 V/µs), gain-bandwidth product (0.55 MHz), and settling time (6.4 µs to 0.1%).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-cell Li-ion, dual-AA, and industrial 5 V rails without level-shifting. |
| Input Offset Voltage (max) | 950 µV at 25°C (TLV2434A variant) - enables DC-coupled amplification of mV-level sensor outputs without nulling circuitry. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves signal integrity in low-amplitude, wideband analog front-ends (e.g., ECG, acoustic sensing). |
| Supply Current per Channel | 150 µA max at 25°C - allows four independent amplifiers in <600 µA total quiescent current for ultra-low-power systems. |
| Common-Mode Input Range | 0 V to 4.5 V (min) with 5 V supply - accommodates ground-referenced inputs and simplifies biasing in single-supply ADC driver stages. |
| Output Drive Capability | ±3 mA into 600 Ω load - sufficient to directly drive SAR ADC reference buffers and telecom line interface circuits. |
| Phase Margin | 66° at unity gain (5 V, RL = 2 kΩ, CL = 100 pF) - ensures stable closed-loop operation without external compensation in unity-gain follower configurations. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 14-terminal surface-mount outline with exposed thermal pad (not electrically connected). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (–IN) for Channels 1–4 | High-impedance CMOS node; accepts signals down to 0 V with no phase reversal. |
| 2, 6, 10, 14 | Non-inverting Input (+IN) for Channels 1–4 | Same rail-to-rail common-mode range as –IN; enables true differential input operation near supply rails. |
| 3, 7, 11, 12 | Output for Channels 1–4 | Rail-to-rail swing: 0.01 V to 4.97 V (5 V supply); drives 600 Ω loads with <1 V drop at ±3 mA. |
| 4 | V– (Ground / Negative Supply) | Reference for single-supply operation; must be connected to system ground or negative rail. |
| 8 | V+ (Positive Supply) | Accepts 2.7–10 V; decoupling capacitor required within 1 cm for stability at high frequencies. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers full dynamic range to ADCs and DACs without headroom loss - e.g., 0–5 V output with 5 V supply improves effective resolution by ≥½ LSB. |
| No phase inversion at supply rails | Eliminates output glitches during input transients crossing V– or V+, critical for closed-loop control and sensor signal integrity. |
| 1 pA typical input bias current | Enables use with >100 MΩ source impedances (e.g., photodiode transimpedance amps) without significant offset error. |
| Low 18 nV/√Hz input voltage noise | Supports high-gain amplification of microvolt-level signals (e.g., thermocouples, strain gauges) without dominating noise floor. |
| 125 µA per channel supply current | Permits integration of four precision op-amps in sub-1 mA total system supply budget - ideal for wearable and IoT edge nodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434IPW | Wider operating temperature range (–40°C to +125°C vs. 0°C to +70°C); identical electrical specs and pinout. | Suitable for under-hood automotive or industrial environments where ambient exceeds 70°C. | Select TLV2434IPW when extended temperature qualification is required; otherwise TLV2434CPW offers cost and inventory advantage for commercial-grade designs. |
| MCP6004-E/ST | Higher supply current (100 µA typ per channel vs. 115 µA typ); lower input offset (1.5 mV max vs. 950 µV max); same TSSOP-14 package. | Better suited for cost-sensitive, non-precision applications where offset drift and noise are less critical. | Choose MCP6004-E/ST for general-purpose buffering where 950 µV VIO is excessive; TLV2434CPW remains preferred for precision sensor signal chains. |
Compared with TLV2434IPW and MCP6004-E/ST, the TLV2434CPW uniquely balances A-grade precision (950 µV VIO), ultra-low noise (18 nV/√Hz), and commercial-temperature optimization - making it the optimal choice for battery-powered instrumentation where accuracy, power, and cost must coexist.

FAQ
What is the maximum supply voltage rating for TLV2434CPW?
The absolute maximum supply voltage for TLV2434CPW is 12 V, but the recommended operating range is 2.7 V to 10 V. Operating above 10 V risks exceeding internal junction temperature limits and may degrade long-term reliability, even if within absolute ratings. Designers should maintain VDD ≤10 V for sustained operation per TI SLOS168G specifications.
Does TLV2434CPW support true rail-to-rail input operation?
No - TLV2434CPW features rail-to-rail *output* only. Its common-mode input voltage range extends from V– to (V+ – 1.3 V) at 5 V supply (i.e., 0 V to 3.7 V), not full rail-to-rail. This is explicitly documented in Section 4.3 (Recommended Operating Conditions) of the datasheet; input voltages beyond this range may cause increased offset or distortion.
Is TLV2434CPW pin-compatible with TLV2434IPW?
Yes - TLV2434CPW and TLV2434IPW share identical TSSOP-14 (PW) package dimensions, pinout, and electrical functionality. The only difference is temperature grade: C-suffix is rated for 0°C to +70°C, while I-suffix extends to –40°C to +125°C. No PCB layout changes are needed when substituting between them in commercial-temperature applications.
What is the typical input bias current of TLV2434CPW at 25°C?
The typical input bias current of TLV2434CPW is 1 pA at 25°C, as confirmed in Section 4.4 (Electrical Characteristics, VDD = 3 V) and Section 4.8 (VDD = 5 V) of the TI datasheet. This ultra-low value enables high-impedance sensor interfacing (e.g., pH electrodes, photodiodes) without significant input error voltage.
Can TLV2434CPW drive a 10 kΩ load with rail-to-rail output swing?
Yes - TLV2434CPW maintains rail-to-rail output swing (e.g., 0.01 V to 4.97 V at 5 V supply) into 10 kΩ loads. Its 600 Ω drive specification guarantees performance under heavier loads; lighter loads like 10 kΩ impose negligible voltage drop and preserve full output range and bandwidth.
