Product details
Overview
TLV2254AIDR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-voltage, micropower applications. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 850 µV maximum input offset voltage at 25°C, operating from 2.7 V to 8 V supply. It is used in precision signal conditioning for high-impedance piezoelectric transducers and battery-powered remote sensing.
For engineers reviewing the TLV2254AIDR datasheet, TLV2254AIDR pinout, TLV2254AIDR application, or TLV2254AIDR equivalent, key selection criteria include its rail-to-rail output swing, 34 µA per-channel quiescent current, common-mode input range extending to the negative rail, low-noise performance, and compatibility with 3-V ADC interfacing in space-constrained industrial and portable designs.
Technical Context
The TLV2254AIDR employs Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω), rail-to-rail output swing, and stable operation with capacitive loads up to 100 pF. Its internal architecture supports both single-supply (2.7–8 V) and split-supply configurations without performance degradation.
It features a gain-bandwidth product of 0.187 MHz at 3 V and 0.2 MHz at 5 V, 63° phase margin, and 15 dB gain margin - enabling unity-gain-stable operation in sensor front-ends and active filters without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - enables direct use with single-cell Li-ion (3.0–3.7 V), two-cell alkaline (3.0 V), or regulated 5-V rails. |
| Quiescent Current | 34 µA per channel - allows four amplifiers to operate continuously on <140 µA total, ideal for multi-channel battery-powered systems. |
| Input Offset Voltage | ≤850 µV max at 25°C - ensures ≤0.85 mV DC error in precision DC-coupled gain stages without trimming. |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level signals from piezo sensors or strain gauges. |
| Common-Mode Input Range | Extends to VDD− (negative rail) - permits direct sensing of ground-referenced signals without level-shifting circuitry. |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–3 V or 0–5 V input ranges, maximizing SNR utilization. |
| Gain-Bandwidth Product | 0.187 MHz at 3 V - sufficient for anti-aliasing filters, sensor buffering, and low-frequency instrumentation (<100 kHz). |
Pinout & Package
TLV2254AIDR is housed in an SOIC-14 (D-14) package with 1.27 mm pitch, 8.65 mm × 3.91 mm body, and tape-and-reel delivery (R suffix). Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives load directly; rail-to-rail swing supports full-scale ADC input. |
| 2 | IN− A | Inverting input - high-impedance node (10¹² Ω); requires matched trace impedance for noise immunity. |
| 3 | IN+ A | Non-inverting input - accepts signals down to VDD−; critical for ground-referenced sensor interfaces. |
| 4 | VDD− / GND | Negative supply / ground reference - must be low-impedance; shared return for all four amplifiers. |
| 5 | IN+ B | Non-inverting input of second amplifier - independent channel; enables dual-sensor differential pairs. |
| 6 | IN− B | Inverting input of second amplifier - matched to Pin 2 for consistent AC coupling design. |
| 7 | OUT B | Output of second amplifier - identical specs to Pin 1; supports parallel or cascaded signal paths. |
| 8 | VDD+ | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability. |
| 9 | OUT C | Output of third amplifier - fully independent; enables three-channel monitoring without cross-talk. |
| 10 | IN− C | Inverting input of third amplifier - same bias current spec (1 pA typ) as Pins 2 and 6. |
| 11 | IN+ C | Non-inverting input of third amplifier - extends common-mode range to VDD− for multi-sensor grounding. |
| 12 | IN+ D | Non-inverting input of fourth amplifier - supports simultaneous conditioning of four analog channels. |
| 13 | IN− D | Inverting input of fourth amplifier - matched layout recommended for thermal drift cancellation. |
| 14 | OUT D | Output of fourth amplifier - rail-to-rail swing ensures consistent interface to multiplexed ADC inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2254IDR | Higher 1500 µV max input offset voltage (vs. 850 µV for TLV2254AIDR); otherwise identical specs and pinout. | Suitable for non-precision applications where offset drift is compensated digitally or via calibration. | Select TLV2254IDR only if cost sensitivity outweighs need for guaranteed low offset; TLV2254AIDR preferred for analog front-ends requiring <1 mV DC error. |
| MCP6004T-I/ST | Higher 100 µA per-channel supply current; 17 nV/√Hz noise; 3.5 mV max offset; SOT-23-14 package (smaller footprint but no thermal pad). | Better noise performance but higher power; limited output drive capability vs. TLV2254AIDR's ±50 mA short-circuit rating. | Choose MCP6004T-I/ST for ultra-compact layouts where board area is constrained and 100 µA/channel is acceptable; TLV2254AIDR remains superior for low-power, high-accuracy, and high-output-drive requirements. |
Compared with TLV2254IDR, TLV2254AIDR offers tighter offset control essential for uncalibrated analog chains; compared with MCP6004T-I/ST, it delivers lower quiescent current and higher output current, making it more suitable for battery-powered instrumentation with demanding DC accuracy and drive needs.

FAQ
What is the maximum operating temperature range for the TLV2254AIDR?
The TLV2254AIDR is rated for operation from −40°C to +125°C, meeting industrial and automotive-grade reliability requirements. This range is validated under the I-suffix qualification, ensuring stable performance in harsh environments such as motor control enclosures or outdoor sensor housings. The device maintains specified offset, noise, and bandwidth parameters across this full range.
Does the TLV2254AIDR support true rail-to-rail input operation?
No - the TLV2254AIDR features rail-to-rail *output* swing but only extends its common-mode input voltage range to the negative rail (VDD−). The positive end is limited to VDD+ − 1.3 V at 3 V supply. This design prioritizes low input bias current and noise over full rail-to-rail input, making it ideal for ground-referenced sensors but requiring external biasing for signals near VDD+.
Can the TLV2254AIDR drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes - the TLV2254AIDR guarantees rail-to-rail output swing into loads ≥10 kΩ at 25°C and VDD = 3 V or 5 V. At heavier loads (e.g., 2 kΩ), output swing compresses slightly (e.g., VOH ≥ 2.8 V at IOH = −150 µA), but full swing is preserved for standard ADC input impedances and most passive filter stages.
Is the TLV2254AIDR pin-compatible with other quad op-amps in SOIC-14 packages?
The TLV2254AIDR uses a standard SOIC-14 pinout matching industry conventions for quad op-amps (e.g., pins 1–7 for Amp A/B, 8 for VDD+, 9–14 for Amp C/D). However, it is not functionally pin-compatible with legacy parts like LM324 due to differences in input stage topology, supply range, and output drive - always verify schematic connectivity and decoupling before substitution.
How does the 34 µA per-channel supply current of the TLV2254AIDR impact battery life in a typical sensor node?
In a four-channel sensor node powered by a 220 mAh CR2032 coin cell, the TLV2254AIDR draws just 136 µA continuously. Assuming 100% efficiency and no other system loads, this enables over 9 years of continuous operation - making it suitable for maintenance-free IoT deployments where battery replacement is impractical.
