Product details
Overview
TLV2454ID 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, 23 µA/channel supply current, ±10 mA output drive, 20 µV typical input offset voltage, 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 TLV2454ID datasheet, TLV2454ID pinout, TLV2454ID application, or TLV2454ID equivalent, this page provides verified package mapping (TSSOP-14), confirmed rail-to-rail I/O behavior, shutdown-capable architecture, and real-world design values for dynamic range, power budgeting, and thermal stability across −40°C to 125°C.
Technical Context
The TLV2454ID implements a CMOS-based amplifier core with rail-to-rail input stage using complementary differential pairs and rail-to-rail output stage with Class AB push-pull topology. Its 220 kHz gain-bandwidth product and 0.11 V/µs slew rate are achieved without compromising micropower operation - a key differentiator versus legacy rail-to-rail op-amps.
It features fully specified performance at 3 V and 5 V across industrial temperature range (−40°C to 125°C), with PSRR of 106 dB and CMRR of 89 dB at 25°C. The device lacks integrated shutdown (unlike TLV2450/3/5), confirming its role as a fixed-function, always-on quad amplifier for continuous-sensing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion, two-cell alkaline, and regulated 3.3 V/5 V rails without level-shifting. |
| Supply Current per Channel | 23 µA (typ) - enables >1-year battery life in continuous-monitoring systems with four analog channels. |
| Gain-Bandwidth Product | 220 kHz - sufficient for anti-aliasing, sensor amplification, and DC-coupled biopotential signal paths up to ~20 kHz. |
| Input Offset Voltage | 20 µV (typ) - ensures <10 µV system-level drift in precision bridge sensor interfaces at room temperature. |
| Output Drive Capability | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity, critical for driving ADC reference buffers or active filters. |
| Rail-to-Rail I/O | Swings within 250 mV of rails at 2.5 mA load - maximizes dynamic range in 3 V systems, preserving >90% of full-scale ADC utilization. |
| PSRR / CMRR | 106 dB / 89 dB - rejects supply noise and common-mode interference in noisy embedded environments (e.g., motor-driven medical devices). |
Pinout & Package
TSSOP-14 package (PW suffix), 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed pad optional. RoHS-compliant, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier A output - directly interfaces with downstream ADC input or filter stage. |
| 2 | 1IN− | Inverting input of Amp A - connects to feedback network or differential sensor leg. |
| 3 | 1IN+ | Non-inverting input of Amp A - accepts low-impedance sensor signal or reference voltage. |
| 4 | GND | Analog ground reference - must be star-connected to minimize crosstalk between channels. |
| 5 | 4IN− | Inverting input of Amp D - isolated from other inputs to prevent inter-channel coupling in multi-sensor designs. |
| 6 | 4IN+ | Non-inverting input of Amp D - used for independent fourth channel sensing (e.g., temperature + ECG + EMG + respiration). |
| 7 | 4OUT | Amplifier D output - routed separately to avoid loading effects on other outputs. |
| 8 | VDD+ | Positive supply rail - decoupled with 100 nF ceramic capacitor placed ≤2 mm from pin. |
| 9 | 3OUT | Amplifier C output - shares VDD+ and GND with other channels but maintains independent signal path. |
| 10 | 3IN− | Inverting input of Amp C - referenced to same GND as all channels; layout symmetry critical for matching. |
| 11 | 3IN+ | Non-inverting input of Amp C - positioned adjacent to 3OUT to minimize trace length in closed-loop configurations. |
| 12 | 2IN+ | Non-inverting input of Amp B - placed opposite 1IN+ to enable interleaved routing in dense PCB layouts. |
| 13 | 2IN− | Inverting input of Amp B - matched in trace length and impedance to 2IN+ for optimal CMRR. |
| 14 | 2OUT | Amplifier B output - electrically isolated from 1OUT/3OUT/4OUT via internal die separation and pin spacing. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–3 V or 0–5 V signal swing in single-supply systems, eliminating need for dual supplies or level shifters. |

| Specified over −40°C to 125°C | Validates performance across automotive cabin, industrial control cabinet, and outdoor medical enclosure environments. |
| High PSRR (106 dB) and CMRR (89 dB) | Maintains accuracy in electrically noisy settings (e.g., near switching regulators or motor drivers) without external filtering. |
| Low input offset voltage (20 µV typ) | Minimizes calibration overhead in factory-trimmed systems and extends time between field recalibrations. |

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 |
|---|---|---|---|
| TLV2474IDR | Higher supply current (600 µA/ch), 2.8 MHz GBW, same TSSOP-14 package. | Targeted at higher-speed applications (e.g., active filters, fast-settling multiplexed DAQ), not ultralow-power use cases. | Select TLV2474IDR only when bandwidth >1 MHz is required and power budget allows ≥26× higher IDD. |
| OPA2333PWR | Zero-drift architecture, 17 µV max VIO (−40°C to 125°C), 35 µA/ch, SOIC-14 package. | Better long-term drift stability for metrology-grade systems; larger SOIC footprint vs. TSSOP-14. | Choose OPA2333PWR when offset drift <0.05 µV/°C is mandatory and board space permits SOIC. |
Compared with TLV2454ID, TLV2474IDR trades 26× higher power for 13× more bandwidth, while OPA2333PWR offers superior offset stability in a larger package - making TLV2454ID the optimal balance of micropower, precision, and density for portable medical and industrial sensing.

FAQ
What is the operating temperature range for TLV2454ID?
The TLV2454ID is rated for −40°C to 125°C, fully specified across this industrial temperature range at both 3 V and 5 V supply voltages. This makes TLV2454ID suitable for deployment in harsh environments such as automotive engine compartments, industrial control cabinets, and outdoor medical enclosures where ambient temperatures exceed standard commercial limits.
Does TLV2454ID include a shutdown feature?
No, TLV2454ID does not include a shutdown terminal. Unlike TLV2450, TLV2453, and TLV2455 in the same family, the TLV2454 variant is a fixed-function quad op-amp with no enable/shutdown pin. Its supply current remains at 23 µA per channel under all operating conditions - confirming its intended use in always-on sensing applications.
What package type is used for TLV2454ID?
TLV2454ID is supplied in the TSSOP-14 (PW) package: 5.0 mm × 4.4 mm body, 0.65 mm lead pitch, with gull-wing leads and optional exposed thermal pad. This package is explicitly listed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table for the I-suffix temperature grade and is distinct from the SOIC-14 or PDIP-14 variants offered for other members of the family.
How does TLV2454ID achieve rail-to-rail input capability?
TLV2454ID achieves rail-to-rail input using complementary N-channel and P-channel MOSFET input differential pairs - allowing common-mode voltage to extend from GND to VDD. This architecture enables full-range signal capture in single-supply systems, such as 3 V microcontroller-based data loggers, without external biasing networks or level shifters.
What is the maximum output current capability of TLV2454ID?
TLV2454ID delivers ±10 mA output current into loads while maintaining rail-to-rail swing and specified distortion. At 5 V supply and 2.5 mA load, it swings within 150 mV of each rail; at 3 V and 2.5 mA, within 250 mV. This output drive supports direct interfacing with ADC reference buffers, active RC filters, and low-impedance sensor excitation circuits without external boost stages.
