Product details
Overview
TLV2455IPW 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 TLV2455IPW datasheet, TLV2455IPW pinout, TLV2455IPW application, or TLV2455IPW equivalent, key selection criteria include its shutdown capability (16 nA/channel), rail-to-rail swing under 2.5-mA load, −40°C to 125°C industrial temperature range, and TSSOP-16 packaging for space-constrained designs.
Technical Context
The TLV2455IPW implements a CMOS input stage with rail-to-rail input common-mode range (0 V to VDD) and rail-to-rail output swing (within 250 mV of rails at 2.5 mA). Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF loads.
It features independent shutdown control per amplifier pair (pins 1/2SHDN and 3/4SHDN), placing outputs in high-impedance state while reducing quiescent current to 16 nA per channel - critical for duty-cycled sensor interfaces and portable ECG monitors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - supports single-cell Li-ion (3.0–3.6 V) and dual-cell alkaline (3–4.5 V) battery operation without regulation. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of DC–20 kHz biosignals (e.g., ECG, pulse oximetry) with minimal phase lag. |
| Supply Current / Channel | 23 µA - allows four independent amplifiers to operate continuously for >1 year on a 200 mAh coin cell. |
| Output Drive | ±10 mA - drives 10 kΩ loads to rail while maintaining linearity, suitable for driving ADC reference buffers or analog multiplexers. |
| Input Offset Voltage | 20 µV (typ) - ensures <10 µV system-level offset error in precision instrumentation amplifier front-ends. |
| Shutdown Current | 16 nA / channel - reduces total system standby power to sub-100 nA when amplifiers are inactive. |
| CMRR / PSRR | 76–89 dB / 88–106 dB - rejects noise from shared supply rails and common-mode interference in noisy industrial environments. |
Pinout & Package
TSSOP-16 package: 5.0 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, exposed thermal pad (not electrically connected).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output terminals | Each drives ±10 mA; rail-to-rail swing enables full-scale use of 12-bit+ ADCs without level-shifting. |
| 1IN−, 1IN+, 2IN−, 2IN+, 3IN−, 3IN+, 4IN−, 4IN+ | Differential input pairs | Rail-to-rail input range (0 V to VDD) accepts unbuffered sensor outputs down to ground or up to supply. |
| VDD+ | Positive supply | Accepts 2.7–6 V; decoupling required within 1 cm for stability at 220 kHz GBW. |
| GND | Ground reference | Common return for all channels; separate analog/digital ground routing recommended. |
| 1/2SHDN, 3/4SHDN | Channel-pair shutdown controls | Active-high logic; pulls to VDD to enable, floats or ties to GND to disable - enables selective channel power gating. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3-V systems - e.g., 0–3 V output swing preserves 12-bit resolution across entire ADC input range. |
| Ultralow 23 µA/channel supply current | Permits continuous monitoring in wearable devices (e.g., glucose meters) with multi-year battery life on CR2032 cells. |
| Independent dual shutdown controls | Allows two amplifiers to remain active for real-time sensing while two others sleep - ideal for time-multiplexed sensor arrays. |
| Specified from −40°C to 125°C | Validates performance in automotive cabin modules, industrial PLC analog inputs, and outdoor environmental sensors. |
| 220 kHz GBW with 56° phase margin | Guarantees stable closed-loop operation with 1000 pF capacitive loads - eliminates need for external compensation in piezoelectric sensor interfaces. |
Applications
| Portable Medical Sensors | Patient Monitoring Front-Ends |
|---|---|
Use Scenario: Amplifying microvolt-level EEG or EMG signals from dry electrodes in ambulatory neurology patches. IC Role / Device Role / Timing Role: Primary signal-conditioning amplifier with rail-to-rail input to capture near-ground bio-potentials and rail-to-rail output to maximize ADC utilization.

IC Role / Device Role / Timing Role: Input-stage buffer and level shifter before isolation amplifiers; shutdown pins reduce leakage during non-acquisition intervals. Use Value: 16 nA shutdown current minimizes standby power in Class II medical devices requiring <10 µA total system sleep current. |
| Data Acquisition Systems | Industrial Sensor Signal Chains |

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 |
|---|---|---|---|
| TLV2475IPW | Higher 600 µA/channel supply current, 2.8 MHz GBW, same TSSOP-16 package and pinout. | Targeted at higher-speed signal paths (e.g., active filters, anti-aliasing), not ultralow-power battery operation. | Select TLV2475IPW only when bandwidth >1 MHz is required and battery life is secondary. |
| LPV521MUTX | Single-channel, 320 nA supply current, 6.2 kHz GBW, SC70-5 package - no shutdown, no quad configuration. | Optimized for nanopower sensor nodes where channel count and speed are secondary to extreme energy efficiency. | Choose LPV521MUTX for single-ended, sub-1 µA applications; TLV2455IPW remains optimal for quad, 220 kHz, shutdown-capable designs. |
Compared with TLV2475IPW and LPV521MUTX, TLV2455IPW uniquely balances 220 kHz bandwidth, quad integration, rail-to-rail I/O, and 23 µA/channel consumption - making it the only option meeting simultaneous requirements for portable medical multichannel front-ends with >1-year battery life.

FAQ
What is the operating temperature range for TLV2455IPW?
The TLV2455IPW is rated for operation from −40°C to +125°C, validated across this full industrial temperature range per its I-suffix specification. This makes TLV2455IPW suitable for under-hood automotive sensors, industrial motor controllers, and outdoor environmental monitoring hardware where ambient temperatures exceed standard commercial limits.
Does TLV2455IPW support true rail-to-rail input and output operation?
Yes, TLV2455IPW supports rail-to-rail input (common-mode range from 0 V to VDD) and rail-to-rail output (swing within 250 mV of each rail at 2.5 mA load). This capability is explicitly confirmed in the datasheet's description and electrical characteristics tables for both 3 V and 5 V supplies, enabling direct interfacing with low-voltage ADCs and microcontrollers without level-shifting circuitry.
How does the shutdown function work on TLV2455IPW?
TLV2455IPW features two independent shutdown controls: pin 1/2SHDN disables amplifiers 1 and 2, while pin 3/4SHDN disables amplifiers 3 and 4. Driving either pin high (≥2 V at VDD = 5 V, ≥0.8 V at VDD = 3 V) activates shutdown, reducing supply current to 16 nA per channel and placing outputs in high-impedance state. This allows selective power gating in multichannel systems without affecting active channels.
What package type is TLV2455IPW supplied in, and is it RoHS compliant?
TLV2455IPW is supplied in a 16-pin TSSOP (PW) package measuring 5.0 mm × 4.4 mm with 0.65 mm pitch. Per Texas Instruments' official documentation and packaging addendum, the TLV2455IPW is RoHS-compliant, lead-free, and halogen-free - meeting IPC/JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements for surface-mount assembly.
Can TLV2455IPW drive capacitive loads, and what is its phase margin?
Yes, TLV2455IPW is characterized for stability with capacitive loads up to 1000 pF, maintaining 56° phase margin and 7 dB gain margin at unity gain with RL = 10 kΩ. This is verified in the datasheet's Figure 24 and "Operating Characteristics" table, confirming suitability for driving ADC input capacitors, long PCB traces, or piezoelectric sensor cables without external compensation.
