Product details
Overview
TLV2434AIPWR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, low-power applications. It delivers 950 µV max input offset voltage (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 portable instrumentation.
For engineers reviewing the TLV2434AIPWR datasheet, TLV2434AIPWR pinout, TLV2434AIPWR application, or TLV2434AIPWR equivalent, key selection criteria include its 0 V to 4.5 V common-mode input range (5 V supply), 600 Ω output drive capability, and guaranteed rail-to-rail output swing - critical for interfacing with 12-bit+ ADCs in space-constrained industrial and medical designs.
Technical Context
The TLV2434AIPWR implements a CMOS input stage with Class AB output stage, supporting true rail-to-rail output swing without phase inversion when inputs approach supply rails. Its extended common-mode input range (0 V to VDD–1.3 V) enables direct sensing of ground-referenced signals in single-supply systems.
It operates across 2.7 V to 10 V supply voltages, with fully characterized performance at 3 V and 5 V. The device exhibits 0.25 V/µs slew rate, 0.55 MHz gain-bandwidth product, and 66° phase margin - ensuring stable unity-gain operation into 2 kΩ//100 pF loads.
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 25°C - enables accurate DC-coupled amplification of mV-level sensor outputs. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - preserves signal integrity in low-amplitude transducer interfaces (e.g., piezoelectric sensors). |
| Supply Current per Channel | 125 µA max - allows four independent amplifiers in ultra-low-power portable devices with multi-day battery life. |
| Common-Mode Input Range | 0 V to 4.2 V (5 V supply) - accepts ground-referenced inputs without external biasing networks. |
| Output Drive Capability | 600 Ω load - drives standard telecom line impedances and ADC input RC filters without buffer stages. |
| Gain-Bandwidth Product | 0.55 MHz - sufficient for anti-aliasing filtering and sensor signal conditioning up to ~50 kHz. |

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 |
|---|---|---|---|
| TLV2434IPWR | Higher input offset voltage (2000 µV max vs. 950 µV); otherwise identical pinout, specs, and package. | Suitable for non-precision applications where cost sensitivity outweighs DC accuracy requirements. | Select TLV2434IPWR only when offset drift and long-term stability are not critical - e.g., audio preamps or basic comparators. |
| MCP6004-E/ST | Lower supply current (1 µA/channel), but higher input offset (1.5 mV) and no guaranteed rail-to-rail input; SOT-23-14 package. | Better for nano-power applications with relaxed accuracy; incompatible pinout prevents drop-in replacement. | Choose MCP6004-E/ST only for ultra-low-power designs where 1 µA/channel justifies 1.5× higher offset and loss of rail-to-rail output swing. |
Compared with TLV2434IPWR, the TLV2434AIPWR provides tighter DC accuracy for precision sensor interfaces, while MCP6004-E/ST trades accuracy and output swing for extreme power savings - making TLV2434AIPWR optimal for battery-powered instrumentation needing both low power and sub-mV offset.

FAQ
What is the maximum operating temperature range for TLV2434AIPWR?
The TLV2434AIPWR is rated for operation from –40°C to +125°C, meeting industrial and automotive under-hood temperature requirements. This specification is confirmed in Section 4.3 (Recommended Operating Conditions) of the official TI datasheet SLOS168G, where the 'I' and 'Q' suffixes define the extended temperature grade applicable to this PW-package variant.
Does TLV2434AIPWR support true rail-to-rail input operation?
No, TLV2434AIPWR features rail-to-rail *output* swing but not rail-to-rail *input*. Its common-mode input voltage range extends from 0 V to VDD–1.3 V (e.g., 0 V to 3.7 V at 5 V supply), as specified in Section 4.3 of the datasheet. This allows ground-referenced inputs but excludes direct connection to VDD without external attenuation.
Can TLV2434AIPWR drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2434AIPWR maintains rail-to-rail output swing into 10 kΩ loads, as verified by VOH = 4.97 V and VOL = 0.01 V at IO = ±100 µA (Section 4.8, VDD = 5 V). Its 600 Ω drive rating refers to minimum load capability - performance improves significantly with higher impedances, preserving full output voltage range.
What is the typical input bias current of TLV2434AIPWR and why does it matter?
The typical input bias current of TLV2434AIPWR is 1 pA, with a maximum of 60 pA over temperature. This ultra-low value minimizes voltage errors in high-impedance circuits - for example, a 10 MΩ source impedance introduces only 10 µV offset error, making it ideal for pH probes, photodiode transimpedance amplifiers, and piezoelectric sensor interfaces where leakage currents degrade accuracy.
Is TLV2434AIPWR pin-compatible with TLV2434IPWR?
Yes, TLV2434AIPWR and TLV2434IPWR share identical pinout, package (TSSOP-14), and electrical interface. The only functional difference is the guaranteed input offset voltage specification: TLV2434AIPWR is binned to ≤950 µV max at 25°C, while TLV2434IPWR allows up to 2000 µV. No PCB layout changes are required for substitution in existing designs.
