Product details
Overview
TLV2455AIPWR 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 TLV2455AIPWR datasheet, TLV2455AIPWR pinout, TLV2455AIPWR application, or TLV2455AIPWR equivalent, key selection criteria include shutdown current (16 nA/ch), rail-to-rail swing capability at 3 V, guaranteed performance over −40°C to 125°C, and TSSOP-16 package compatibility with high-density PCB layouts.
Technical Context
The TLV2455AIPWR 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, and it features independent shutdown control per amplifier pair (pins 1/2SHDN and 3/4SHDN).
It operates across single-supply voltages from 2.7 V to 6 V (±1.35 V to ±3 V split), with full specifications validated at both 3 V and 5 V. Input bias current remains below 5 nA over temperature, and PSRR exceeds 106 dB at DC, supporting robust operation in noisy mixed-signal environments.
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 logic rails without level shifting |
| Gain-Bandwidth Product | 220 kHz - supports stable amplification of low-frequency sensor signals (ECG, thermistor, strain gauge) up to ~20 kHz |
| Supply Current per Channel | 23 µA - allows four op-amps to operate continuously on <100 µA total, ideal for multi-channel wearable monitors |
| Input Offset Voltage | 300 µV (max, 25°C), 1300 µV (max, full temp range) - ensures sub-mV DC accuracy in precision instrumentation |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly, eliminating need for external buffers in analog front-ends |
| Shutdown Current | 16 nA per channel - reduces system standby power by >99.9% when amplifiers are inactive |
| Common-Mode Rejection | 76 dB (min, 25°C) - maintains signal integrity in presence of ground bounce or supply ripple |
Pinout & Package
TSSOP-16 package with 0.65 mm pitch, 5.0 mm × 4.4 mm body, and exposed thermal pad (not electrically connected). RoHS-compliant, lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | OUT (1OUT, 2OUT, 3OUT, 4OUT) | Amplifier output terminals - rail-to-rail swing supports full dynamic range utilization in 3 V systems |
| 2, 5, 12, 15 | IN− (1IN−, 2IN−, 3IN−, 4IN−) | Inverting inputs - CMOS input stage enables high-impedance sensing from passive transducers |
| 3, 4, 13, 14 | IN+ (1IN+, 2IN+, 3IN+, 4IN+) | Non-inverting inputs - rail-to-rail common-mode range accepts signals from 0 V to VDD |
| 6, 7 | 1/2SHDN, 3/4SHDN | Independent dual shutdown controls - enables selective power gating of amplifier pairs to optimize system-level power |
| 10 | GND | Analog ground reference - requires low-impedance connection to minimize noise coupling between channels |
| 11 | VDD+ | Positive supply - decoupling capacitor (0.1 µF) required within 1 cm for stability at full bandwidth |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables maximum signal swing in 3 V systems - e.g., 0–3 V ADC input range fully utilized without clipping |
| Ultralow quiescent current | 23 µA/channel allows continuous monitoring in energy-harvested or coin-cell-powered devices |
| Independent dual shutdown | Reduces active channel count dynamically - e.g., two amplifiers process ECG while two remain in 16 nA sleep mode |
| Specified over −40°C to 125°C | Validated for automotive cabin sensors and industrial field transmitters without derating |
| High output drive (±10 mA) | Drives RC anti-aliasing filters or long traces directly - avoids added buffer ICs and layout complexity |

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 |
|---|---|---|---|
| TLV2455IPW | Same electrical specs; PW suffix denotes same TSSOP-16 package but without 'R' tape-and-reel designation | No functional difference - used in manual assembly or small-batch prototyping where reel packaging is unnecessary | Select TLV2455IPW for hand-soldered evaluation or low-volume production; TLV2455AIPWR preferred for automated SMT lines requiring tape-and-reel feed |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower VIO (2 µV typ), higher GBW (350 kHz), but 17 µA higher IDD (40 µA/ch) | Better DC precision for thermocouple or strain gauge bridges; less suitable for ultra-low-power battery life targets | Choose OPA2333PWR when offset drift dominates error budget; retain TLV2455AIPWR when <25 µA/channel and shutdown capability are mandatory |
Compared with TLV2455IPW, TLV2455AIPWR offers identical performance with standardized tape-and-reel packaging for SMT manufacturing; versus OPA2333PWR, it trades zero-drift precision for 60% lower quiescent current and integrated shutdown - making it superior for always-on, multi-day battery operation.

FAQ
What is the operating temperature range for TLV2455AIPWR?
The TLV2455AIPWR is specified for operation from −40°C to +125°C. This extended industrial temperature range is validated across all key parameters including input offset voltage, supply current, and gain-bandwidth product - ensuring reliable performance in automotive cabin modules, industrial field transmitters, and outdoor environmental sensors without thermal derating.
Does TLV2455AIPWR support true rail-to-rail input and output operation?
Yes, TLV2455AIPWR 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 confirmed in the datasheet's Electrical Characteristics tables at both 3 V and 5 V supply, enabling full utilization of ADC input ranges in low-voltage systems without external level-shifting circuitry.
How does the shutdown feature work on TLV2455AIPWR?
The TLV2455AIPWR integrates two independent shutdown controls: pin 6 (1/2SHDN) disables amplifiers 1 and 2, while pin 7 (3/4SHDN) disables amplifiers 3 and 4. Driving either pin low (≤0.5 V at 3 V supply) places the corresponding outputs in high-impedance state and reduces supply current to 16 nA per channel - verified in the Shutdown Current (IDD(SHDN)) specification table.
What is the maximum load capacitance TLV2455AIPWR can drive stably?
TLV2455AIPWR maintains ≥56° phase margin driving up to 1000 pF capacitive load with 10 kΩ resistive load, as shown in Figure 24 of the datasheet. For unity-gain stable operation with heavier capacitive loads (>100 pF), a series resistor (≥100 Ω) between amplifier output and load is recommended to preserve stability and prevent peaking.
Is TLV2455AIPWR pin-compatible with other quad op-amps in TSSOP-16?
No - TLV2455AIPWR uses a proprietary pinout optimized for dual independent shutdown control and channel separation. It is not pin-compatible with standard quad op-amps like LM324 or TLV2774. The pin mapping (e.g., 1/2SHDN on pin 6, 3/4SHDN on pin 7, GND on pin 10) must be verified against the official TI datasheet SLOS218F before PCB layout.
