Product details
Overview
TLV2254ID from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, micropower operation. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 34 µA per channel supply current across 2.7 V to 8 V supply range - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2254ID datasheet, TLV2254ID pinout, TLV2254ID application, or TLV2254ID equivalent, key selection criteria include its rail-to-rail output swing, sub-1 µA input bias current, 850 µV max input offset voltage (A-grade), and compatibility with single-supply ADC driver stages requiring wide common-mode input range down to the negative rail.
Technical Context
The TLV2254ID uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and low input bias current while maintaining rail-to-rail output capability. Its architecture supports both single-supply (2.7 V–8 V) and split-supply operation without performance degradation.
It features fully characterized operation from −40°C to +125°C, with guaranteed common-mode input voltage range extending to the negative rail and output swing within 100 mV of both rails under light load - critical for maximizing dynamic range in 3-V systems interfacing with 12-bit+ ADCs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use in Li-ion single-cell and dual-cell battery systems without regulation. |
| Input Offset Voltage (Max) | 850 µV at TA = 25°C - ensures ≤0.02% gain error in unity-gain buffer or 10× gain transimpedance configurations. |
| Input Bias Current (Typ) | 1 pA - preserves signal integrity when amplifying high-impedance sources like piezoelectric sensors or pH electrodes. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - four times lower than prior micropower CMOS op amps, reducing noise floor in precision analog front-ends. |
| Quiescent Current | 34 µA per channel - allows four independent amplifiers to operate continuously on <150 µA total, ideal for always-on monitoring nodes. |
| Output Swing | Rail-to-rail - delivers full 0 V to VDD output range into ≥10 kΩ loads, maximizing ADC utilization in 3-V systems. |
| Gain-Bandwidth Product | 0.187 MHz at VDD = 3 V - supports stable DC-coupled gain up to ~10× with adequate phase margin for sensor signal conditioning. |
Pinout & Package
TLV2254ID is housed in an 14-pin SOIC (Small Outline Integrated Circuit) package (D package), with standard JEDEC MS-012AC footprint and 1.27 mm pitch. The device is rated for −40°C to +125°C operating temperature range and features exposed pad not present in this variant.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254AID | Lower 850 µV max input offset voltage (vs. 1500 µV for TLV2254ID); otherwise identical specs and pinout. | Suitable where initial offset error must be minimized without trimming - e.g., medical sensor calibrations or high-accuracy RTD bridges. | Select TLV2254AID when system-level offset budget requires tighter initial VIO; same PCB layout and thermal profile. |
| OPA2333P | Zero-drift architecture (0.02 µV/°C drift), 17 nV/√Hz noise, but higher 17 µA/channel current and only dual-channel configuration. | Better for ultra-stable DC applications (e.g., precision weigh scales), but requires two packages for quad functionality and lacks same temp range. | Choose OPA2333P only if long-term drift dominates error budget and dual-channel count suffices; not drop-in compatible. |
Compared with TLV2254AID, the TLV2254ID trades initial offset accuracy for cost-sensitive industrial use; versus OPA2333P, it offers true quad integration and wider temperature range at the expense of drift performance - making TLV2254ID optimal for cost-constrained, multi-channel, battery-operated systems requiring robustness over decades-long calibration intervals.

FAQ
What is the maximum operating temperature range for the TLV2254ID?
The TLV2254ID is specified for continuous operation from −40°C to +125°C ambient temperature, meeting industrial and automotive under-hood requirements. This rating is confirmed in the Absolute Maximum Ratings table and Operating Conditions section of the SLOS185D datasheet, with full electrical characterization across this range.
Does the TLV2254ID support true rail-to-rail input capability?
No - the TLV2254ID features rail-to-rail *output* swing but only extends its common-mode input voltage range to the negative rail (V−). The positive end is limited to VDD − 1.3 V at 3 V supply, per Recommended Operating Conditions. Input common-mode range is not rail-to-rail, unlike some newer TI op amps such as the TLV9064.
Can the TLV2254ID drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes - the TLV2254ID guarantees rail-to-rail output swing into ≥10 kΩ loads at 25°C, as shown in Figure 1 (VOH/VOL vs. output current) and Electrical Characteristics tables. At full temperature range (−40°C to +125°C), output swing remains within 100 mV of each rail under 50 µA load, supporting most 12-bit+ ADC input requirements.
Is the TLV2254ID pin-compatible with the TLV2254AID?
Yes - TLV2254ID and TLV2254AID share identical SOIC-14 (D) package, pinout, and all electrical specifications except input offset voltage (VIO). The TLV2254AID specifies 850 µV max VIO at 25°C, while TLV2254ID specifies 1500 µV max; all other parameters including supply current, noise, and output drive are identical and interchangeable at board level.
What is the typical supply current per channel for TLV2254ID at 3 V supply?
The TLV2254ID draws 34 µA per channel typical supply current at VDD = 3 V and TA = 25°C, resulting in 136 µA total for all four amplifiers. This value is confirmed in the "Very Low Power . . . 34 µA Per Channel Typ" headline and Electrical Characteristics tables (IDD = 135 µA typ for four amplifiers at VDD = 3 V).
