Product details
Overview
TLV2455AIPW 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 20 µV typical input offset voltage across 2.7 V to 6 V operation - enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455AIPW datasheet, TLV2455AIPW pinout, TLV2455AIPW application, or TLV2455AIPW equivalent, key selection criteria include shutdown current (16 nA/channel), rail-to-rail swing under load, input offset stability over temperature, and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The TLV2455AIPW 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 load). Its internal architecture supports stable unity-gain operation with 56° phase margin into 1000 pF capacitive 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 power-gated subsystems.
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. |
| Gain-Bandwidth Product | 220 kHz - enables stable amplification of DC–20 kHz biosignals (ECG, pulse oximetry) with minimal phase lag. |
| Input Offset Voltage (typ) | 20 µV - ensures ≤0.2 mV error in 100× gain instrumentation stages at room temperature. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating need for external buffer stages in analog front-ends. |
| Shutdown Supply Current | 16 nA/channel - extends battery life by >1000× vs active mode in intermittent-sampling applications. |
| Power Supply Rejection Ratio | 106 dB - suppresses ripple from switching regulators feeding mixed-signal PCBs. |
| Operating Temperature Range | −40°C to 125°C - qualified for automotive cabin and industrial sensor environments. |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed thermal pad (not electrically connected). Designed for automated assembly and thermal relief in compact portable PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | Output (OUT1–OUT4) | Amplifier outputs; each capable of rail-to-rail swing and ±10 mA sourcing/sinking. |
| 2, 4, 10, 12 | Inverting Input (IN−1–IN−4) | Differential inputs with 10⁹ Ω input resistance and 4.5 pF capacitance - minimizes loading on high-Z sensor nodes. |
| 3, 5, 11, 13 | Non-inverting Input (IN+1–IN+4) | Matched to IN− pins; supports unity-gain follower and precision difference amplification. |
| 6, 14 | Shutdown Control (1/2SHDN, 3/4SHDN) | Active-high logic inputs; asserting either disables its associated amplifier pair and places outputs in high-Z state. |
| 7 | GND | Analog ground reference; requires low-impedance connection to minimize noise coupling between channels. |
| 15 | VDD+ | Positive supply rail; decoupling capacitor (0.1 µF) required within 2 mm for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3 V systems - e.g., 0–3 V ADC input scaling without level-shifters. |
| Ultralow shutdown current | 16 nA/channel allows microcontroller-gated amplification in multi-sensor nodes with <1 µA standby budget. |
| 220 kHz GBW at 23 µA | Outperforms legacy micropower op-amps (e.g., TLC27L4) by >2× bandwidth per µA, easing filter design in anti-aliasing stages. |
| Specified at 3 V and 5 V | Guarantees performance across battery discharge curves - no derating needed from 3.6 V fresh to 2.8 V end-of-life. |
| −40°C to 125°C operation | Validated for under-hood automotive and industrial edge nodes where ambient temperature exceeds 85°C. |
Applications
| Portable ECG Monitor Front-End | Low-Power Data Acquisition System |
|---|---|

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 |
|---|---|---|---|
| TLV2455CDR | Same electrical specs; SOIC-14 package (no shutdown pins), 0°C to 70°C temp range, higher 40 µA/channel IDD. | Lacks independent shutdown control; unsuitable for duty-cycled multi-channel sensing. | Select when board space permits SOIC and temperature range is limited to commercial grade. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2455AIPW's 0.3 µV/°C; 35 µA/channel IDD; no shutdown function. | Superior DC precision but higher power and no power gating - better for static sensor offsets, worse for burst-mode operation. | Select when long-term offset stability dominates over shutdown capability and power budget. |
Compared with TLV2455CDR, TLV2455AIPW adds shutdown control and extended temperature support at identical AC performance; versus OPA2333AIDR, it trades zero-drift precision for 45% lower quiescent current and integrated power gating - making it optimal for battery-constrained, intermittently active systems.

FAQ
What is the maximum operating supply voltage for TLV2455AIPW?
The absolute maximum supply voltage for TLV2455AIPW is 7 V, but the recommended operating range is 2.7 V to 6 V. Operation above 6 V risks exceeding safe junction temperature and may degrade long-term reliability. The device is fully specified at both 3 V and 5 V, making it ideal for single-cell Li-ion (2.8–4.2 V) and regulated 3.3 V/5 V systems.
Does TLV2455AIPW support true rail-to-rail output swing under load?
Yes, TLV2455AIPW achieves rail-to-rail output swing - within 250 mV of each supply rail while sourcing or sinking 2.5 mA - verified across the full −40°C to 125°C temperature range. This enables direct interfacing with 3 V ADCs and low-voltage logic without external level-shifting circuitry.
How does the shutdown feature work on TLV2455AIPW?
TLV2455AIPW has two independent shutdown inputs: pin 6 (1/2SHDN) controls amplifiers 1 and 2, and pin 14 (3/4SHDN) controls amplifiers 3 and 4. Driving either pin high (≥2 V at VDD = 5 V or ≥0.8 V at VDD = 3 V) disables its pair, placing outputs in high-impedance state and reducing supply current to 16 nA per channel.
What is the input offset voltage specification for TLV2455AIPW over temperature?
TLV2455AIPW has a typical input offset voltage of 300 µV at 25°C and a maximum of 1300 µV across the full −40°C to 125°C range. Its temperature coefficient is 0.3 µV/°C, meaning offset drift contributes less than 30 µV over a 100°C span - sufficient for most portable medical and industrial sensor applications without trimming.
Is TLV2455AIPW pin-compatible with other devices in the TLV245x family?
No - TLV2455AIPW uses a 16-pin TSSOP (PW) package with dedicated shutdown pins, while TLV2454 (quad, no shutdown) uses the same footprint but repurposes pins 6 and 14 as NC. TLV2452/TLV2453 use 8-pin and 10-pin MSOP packages respectively. Direct substitution requires PCB layout revision due to differing pin count, function mapping, and package dimensions.
