Product details
Overview
TLV2434AIDR from Texas Instruments is a quad-channel, rail-to-rail output operational amplifier optimized for low-voltage (2.7 V to 10 V) single-supply operation. It delivers 950 µV max input offset voltage (at 25°C), 18 nV/√Hz input voltage noise at 1 kHz, 125 µA per channel supply current, and full rail-to-rail output swing - enabling high-accuracy signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2434AIDR datasheet, TLV2434AIDR pinout, TLV2434AIDR application, or TLV2434AIDR equivalent, key selection criteria include its guaranteed 0 V to 4.5 V common-mode input range with 5 V supply, 600 Ω output drive capability, no phase inversion behavior, and A-grade precision specification across –40°C to +125°C temperature range.
Technical Context
The TLV2434AIDR implements a CMOS-input, Class AB output stage architecture that enables true rail-to-rail output swing while maintaining stable operation under heavy capacitive loads (up to 100 pF). Its extended common-mode input range (0 V to VDD–1.3 V) eliminates need for level-shifting in single-supply systems interfacing with ground-referenced sensors.
It features internal biasing that suppresses phase inversion when inputs approach either supply rail - a critical reliability attribute for monitoring circuits where input transients may exceed rails. The device is fully characterized for 3 V and 5 V operation, with specified performance over industrial and automotive temperature ranges (I and Q suffixes).
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 regulation |
| Input Offset Voltage (max) | 950 µV at 25°C - ensures ≤0.02% gain error in 1 V full-scale instrumentation amplifiers |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal chains (e.g., thermopiles, strain gauges) |
| Supply Current per Channel | 150 µA max - enables >1-year battery life in always-on IoT node front-ends |
| Common-Mode Input Range | 0 V to 4.5 V (min) at 5 V supply - accepts ground-referenced signals without external biasing |
| Output Drive Capability | 600 Ω load - directly drives SAR ADC reference buffers and analog multiplexers |

Pinout & Package
TLV2434AIDR is housed in a 14-pin SOIC (D package) with standard quad op-amp pinout. Thermal pad is not present; power dissipation is managed via PCB copper area per JEDEC MO-153.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 10, 13 | Output | Four independent rail-to-rail output terminals - each capable of sourcing/sinking ±3 mA into 600 Ω |
| 2, 5, 8, 11 | Inverting Input (–) | Differential input pins with 1000 GΩ common-mode resistance - suitable for high-Z sensor buffering |
| 3, 6, 9, 12 | Non-Inverting Input (+) | Matched to inverting inputs; supports DC-coupled configurations down to 0 V common-mode |
| 4 | V– (GND) | Ground reference for single-supply operation - must be low-impedance return path for all channels |
| 14 | V+ | Positive supply terminal - decoupling capacitor (0.1 µF) required within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 20 mV of both rails at 3 mA load - maximizes dynamic range into 12-bit+ ADCs |
| No phase inversion | Stable closed-loop behavior even when inputs exceed supply rails - eliminates need for clamping diodes |
| Low input bias current | 1 pA typical - prevents signal degradation in pH electrodes, photodiode transimpedance stages |
| Extended common-mode range | 0 V to VDD–1.3 V - enables direct connection to unbuffered resistive sensor bridges |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434IDR | Higher 2000 µV max input offset voltage (vs. 950 µV); same pinout, package, and supply specs | Suitable for non-precision gain stages where offset drift is less critical than cost | Select TLV2434IDR only if system-level calibration compensates for higher initial offset |
| MCP6004-E/SL | Higher 150 µA typical supply current; 17 nV/√Hz noise; no guaranteed no-phase-inversion behavior | Better suited for general-purpose filtering where rail-to-rail input is not required | Choose MCP6004-E/SL only when lower cost outweighs need for guaranteed phase inversion immunity and tighter offset spec |
Compared with TLV2434IDR and MCP6004-E/SL, the TLV2434AIDR provides superior DC accuracy and robustness against input overdrive - making it the preferred choice for calibrated sensor interfaces where long-term stability and rail tolerance are design-critical.

FAQ
What is the maximum operating temperature range for TLV2434AIDR?
The TLV2434AIDR is rated for operation from –40°C to +125°C, meeting industrial and extended-temperature requirements. This rating is confirmed in Section 4.3 (Recommended Operating Conditions) and validated across all electrical parameters in the I-suffix specifications (quad version) of the official TI datasheet SLOS168G.
Does TLV2434AIDR support true rail-to-rail input operation?
No, TLV2434AIDR does not support rail-to-rail input. Its common-mode input voltage range is specified as 0 V to VDD–1.3 V (e.g., 0 V to 3.7 V at 5 V supply). However, it guarantees no phase inversion when inputs approach the rails - a distinct advantage over standard CMOS op-amps.
Can TLV2434AIDR drive a 10 nF capacitive load directly?
TLV2434AIDR is characterized for stable operation with up to 100 pF capacitive load (per Section 4.5 and 4.9). Driving 10 nF (10,000 pF) directly will cause severe overshoot and potential oscillation. A series isolation resistor (≥100 Ω) or external compensation network is required for such loads.
Is TLV2434AIDR pin-compatible with other quad op-amps in SOIC-14?
TLV2434AIDR follows the industry-standard quad op-amp pinout (pin 1 = OUT A, pin 2 = IN– A, pin 3 = IN+ A, pin 4 = GND, etc.), matching LM324, TLV2464, and MCP6004. However, absolute pin compatibility requires verification of supply sequencing, ESD structure, and output stage behavior - TI confirms functional equivalence only within the TLV243x family.
What is the typical slew rate of TLV2434AIDR at 5 V supply?
The typical slew rate of TLV2434AIDR is 0.25 V/µs at 5 V supply, measured under unity-gain configuration with 2 kΩ load and 100 pF capacitance (Section 4.9, Table). This supports bandwidths up to ~100 kHz for small-signal step responses, sufficient for most sensor and control loop applications.
