Product details
Overview
TLV2455AID 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 −40°C to 125°C, enabling precision signal conditioning in battery-powered medical sensors and data acquisition front-ends.
For engineers reviewing the TLV2455AID datasheet, TLV2455AID pinout, TLV2455AID application, or TLV2455AID equivalent, key selection considerations include its shutdown capability (16 nA/channel), rail-to-rail swing under 2.7–6 V operation, guaranteed performance at 3 V, and TSSOP-16 packaging for high-density analog signal chains.
Technical Context
The TLV2455AID 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), supporting single-supply operation down to 2.7 V. Its internal architecture includes independent shutdown control per amplifier pair (pins 1/2SHDN and 3/4SHDN), enabling selective channel power gating without affecting active sections.
It features 106 dB PSRR and 89 dB CMRR at 25°C with VDD = 5 V, and maintains stable unity-gain operation with ≥56° phase margin into 1000 pF capacitive loads-critical for driving ADC inputs or long traces in compact sensor nodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 6 V - Enables direct interface with Li-ion, coin-cell, and 3.3 V logic supplies without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - Supports DC-coupled sensor amplification and low-frequency filtering up to ~20 kHz with stable closed-loop gain. |
| Supply Current per Channel | 23 µA - Allows four independent amplifiers to operate continuously on <100 µA total, extending battery life in wearable monitors. |
| Input Offset Voltage (typ) | 20 µV - Minimizes DC error in precision bridge sensor interfaces and thermocouple cold-junction compensation. |
| Output Drive Capability | ±10 mA - Drives 10 kΩ loads to rail while maintaining linearity, sufficient for driving SAR ADC reference buffers or LED bias circuits. |
| Shutdown Current per Channel | 16 nA - Reduces quiescent power by >1500× when inactive, critical for duty-cycled sensor wake-up architectures. |
| Operating Temperature Range | −40°C to 125°C - Qualified for automotive cabin modules, industrial process transmitters, and outdoor environmental sensors. |
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 space-constrained PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT, 2OUT, 3OUT, 4OUT | Amplifier output terminals | Deliver rail-to-rail output swing; each capable of sourcing/sinking ±10 mA into resistive loads. |
| 1IN−, 2IN−, 3IN−, 4IN− | Inverting input terminals | High-impedance CMOS inputs (10⁹ Ω) with rail-to-rail common-mode range (0 V to VDD). |
| 1IN+, 2IN+, 3IN+, 4IN+ | Non-inverting input terminals | Matched to inverting inputs; enable precision differential, instrumentation, and buffer configurations. |
| GND | Analog ground reference | Single ground connection shared by all four amplifiers; requires low-impedance local decoupling. |
| VDD+ | Positive supply rail | Accepts 2.7–6 V; powers all four op-amps and internal shutdown logic simultaneously. |
| 1/2SHDN, 3/4SHDN | Channel-pair shutdown controls | Active-high logic inputs; placing either low disables corresponding two amplifiers and reduces IDD to 16 nA/channel. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input/output | Enables full dynamic range utilization in 3 V systems-e.g., 0–3 V output swing preserves 12-bit ADC resolution without clipping. |
| Ultralow 23 µA/channel supply current | Permits continuous operation of four independent signal paths on sub-100 µA total budget-ideal for always-on biosensor front-ends. |
| Independent dual-pair shutdown | Allows selective deactivation of unused channels (e.g., disable A+B during sleep while keeping C+D active for wake-on-event detection). |
| 20 µV typical input offset voltage | Reduces calibration overhead in strain gauge or RTD measurement circuits where offset drift dominates system error budget. |
| Stable with 1000 pF capacitive load | Eliminates need for external isolation resistors when driving sampling capacitors in successive-approximation ADCs. |
Applications
| Portable Patient Monitoring | Industrial Sensor Signal Conditioning |

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 |
|---|---|---|---|
| TLV2474AIPW | Higher 600 µA/channel supply current, 2.8 MHz GBW, no shutdown function | Better suited for higher-speed signal paths (>100 kHz) but incompatible with µA-level power budgets | Select when bandwidth >1 MHz is required and power is secondary to speed |
| LPV821RGTR | Lower 650 nA/channel supply current, 10 kHz GBW, single-channel, no shutdown | Optimized for nano-power sensor preamps but lacks quad integration and shutdown control | Select for ultra-low-power single-ended front-ends where channel count and shutdown are not needed |
Compared with TLV2455AID, TLV2474AIPW trades 26× higher supply current for 13× greater bandwidth and no power management; LPV821RGTR reduces current by 35× but sacrifices 22× bandwidth, quad integration, and shutdown-making TLV2455AID the only option balancing µA quiescent current, 220 kHz bandwidth, quad density, and channel-selectable shutdown in TSSOP-16.

FAQ
What is the maximum operating temperature range for TLV2455AID?
The TLV2455AID is specified for operation from −40°C to +125°C, making it suitable for under-hood automotive, industrial control, and outdoor environmental applications. This extended temperature grade is confirmed in the "Recommended Operating Conditions" table of the SLOS218F datasheet, where the "I-suffix" designation explicitly defines this range.
Does TLV2455AID support true rail-to-rail input and output operation?
Yes, TLV2455AID 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 is explicitly stated in the device description and verified in electrical characteristics tables showing VOH ≥ 2.85 V and VOL ≤ 0.16 V at VDD = 3 V and IOL = 500 µA.
How does the shutdown feature work on TLV2455AID?
TLV2455AID has two independent shutdown pins: 1/2SHDN (pin 5) controls amplifiers 1 and 2, and 3/4SHDN (pin 11) controls amplifiers 3 and 4. Driving either pin low disables its associated pair, reducing supply current per channel to 16 nA. The outputs enter high-impedance state, preserving signal integrity on shared buses during sleep modes.
What package type is used for TLV2455AID?
TLV2455AID is packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package) with 0.65 mm lead pitch and 5.0 mm × 4.4 mm body dimensions. This is confirmed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table, where "TLV2455AID" maps to the "PW" package code, defined as TSSOP in TI's packaging nomenclature.
Can TLV2455AID operate from a single 3.0 V supply?
Yes, TLV2455AID is fully specified at 3.0 V, with all key parameters-including gain-bandwidth (220 kHz), input offset voltage (20 µV typ), and output drive (±10 mA)-guaranteed across the −40°C to 125°C range. The "Recommended Operating Conditions" table explicitly lists VDD min = 2.7 V, confirming robust functionality at 3.0 V nominal.
