Product details
Overview
TLV2454AID from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultralow-power, low-voltage portable systems. It delivers 220 kHz gain-bandwidth, ±10 mA output drive, 23 µA/channel supply current, and operates from 2.7 V to 6 V - enabling high-precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2454AID datasheet, TLV2454AID pinout, TLV2454AID application, or TLV2454AID equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, TSSOP-14 package, rail-to-rail I/O swing within 250 mV of rails at 2.5 mA load, and shutdown capability (16 nA/channel) critical for power-constrained embedded designs.
Technical Context
The TLV2454AID implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing, supporting single-supply operation down to 2.7 V. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are specified at 5 V with 10 kΩ load and 150 pF capacitance.
It features an internal shutdown control logic that places outputs in high-impedance state and reduces quiescent current to 16 nA per channel when SHDN is driven low. The device is fully characterized across −40°C to 125°C and supports stable operation with capacitive loads up to 1000 pF (56° phase margin).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - enables direct interface with Li-ion, 3.3 V, and 5 V systems without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - sufficient for DC-coupled sensor amplification, filter stages, and low-frequency instrumentation. |
| Supply Current per Channel | 23 µA - allows four independent amplifiers to operate continuously on microamp-level battery budgets. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads while maintaining rail-to-rail swing, suitable for driving ADC reference buffers or small actuators. |
| Input Offset Voltage (max) | 1300 µV - ensures <1 LSB error in 12-bit systems with 5 V full-scale range. |
| Shutdown Current per Channel | 16 nA - extends battery life by >1000× vs active mode during idle periods in portable devices. |
| Common-Mode Rejection Ratio | 76 dB (min) - suppresses noise from shared ground paths in multi-sensor PCB layouts. |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch), thermally enhanced for continuous operation at 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUTx | Amplifier output terminals - rail-to-rail swing supports full dynamic range utilization in single-supply data acquisition. |
| 2, 6, 10, 14 | IN−x | Inverting inputs - high impedance (>10⁹ Ω) minimizes loading on high-Z sensor sources like pH electrodes or thermopiles. |
| 3, 7, 11, 12 | IN+x | Non-inverting inputs - rail-to-rail common-mode range (0 V to VDD) enables direct connection to unbuffered resistive dividers or DAC outputs. |
| 4 | GND | Analog ground reference - dedicated pin isolates sensitive analog return path from digital noise coupling. |
| 8 | VDD+ | Positive supply - accepts 2.7–6 V; no separate negative rail required for single-supply operation. |
| 12 | 3/4SHDN | Shared shutdown control for channels 3 and 4 - enables selective power gating of dual amplifier pairs to optimize system-level power sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–VDD signal swing in single-supply configurations, maximizing ADC resolution without external biasing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2454CDR | Same architecture and specs, but rated for 0°C to 70°C and supplied in tape-and-reel SOT-23-compatible packaging. | Limited to commercial-temperature consumer electronics; lacks extended thermal qualification for industrial deployment. | Select only for cost-sensitive, non-critical ambient environments where full −40°C to 125°C validation is unnecessary. |
| OPA2333AIDRGR | Zero-drift architecture, 0.02 µV/°C offset drift, 35 µA/channel, 350 kHz GBW - higher precision but 50% higher current draw. | Better for DC-critical applications (e.g., precision weight scales); less suitable for long-duration battery operation due to higher IDD. | Choose when offset drift dominates error budget over quiescent power; avoid when >23 µA/channel violates system-level energy targets. |
Compared with TLV2454CDR, TLV2454AID provides guaranteed operation at 125°C and tighter input offset voltage limits across temperature - essential for automotive and industrial control. Versus OPA2333AIDRGR, TLV2454AID trades offset drift performance for 30% lower supply current and proven stability with capacitive loads, making it optimal for general-purpose low-power sensing.

FAQ
What is the operating temperature range for TLV2454AID?
The TLV2454AID is rated for −40°C to 125°C free-air temperature operation. This extended industrial temperature range is validated per TI's characterization methodology and supports reliable deployment in automotive cabin modules, industrial PLC I/O cards, and outdoor environmental monitoring equipment without thermal derating.
Does TLV2454AID support true rail-to-rail input and output operation?
Yes, TLV2454AID supports rail-to-rail input common-mode voltage (0 V to VDD) and rail-to-rail output swing (within 250 mV of each rail at 2.5 mA load). This capability is confirmed in the datasheet's electrical characteristics tables and typical performance curves for both 3 V and 5 V supplies.
What is the shutdown behavior of TLV2454AID?
When the 3/4SHDN pin (Pin 12) is driven low, TLV2454AID disables channels 3 and 4, placing their outputs in high-impedance state and reducing supply current to 16 nA per channel. Channels 1 and 2 remain active unless separately controlled via external circuitry - no integrated shutdown for all four channels.
What package type is used for TLV2454AID?
TLV2454AID is supplied in a 14-pin TSSOP package (PW suffix), measuring 4.4 mm × 5.0 mm with 0.65 mm lead pitch. This thermally enhanced surface-mount package supports reflow soldering and provides adequate power dissipation for continuous operation at 125°C ambient.
How does TLV2454AID compare to TLV2454CD in terms of specifications?
TLV2454AID and TLV2454CD share identical electrical specifications (GBW, IDD, VIO, etc.) but differ in temperature rating: TLV2454AID is qualified for −40°C to 125°C, while TLV2454CD is limited to 0°C to 70°C. Both use the same TSSOP-14 package and pinout, but TLV2454AID undergoes additional high-temperature screening and characterization.
