Product details
Overview
TLV2455IDR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultra-low-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 TLV2455IDR datasheet, TLV2455IDR pinout, TLV2455IDR application, or TLV2455IDR equivalent, key selection criteria include shutdown-enabled power management (16 nA/channel), rail-to-rail swing at 3 V/5 V, guaranteed operation across −40°C to 125°C, and TSSOP-16 packaging for space-constrained analog signal chains.
Technical Context
The TLV2455IDR 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 loads, and features independent shutdown control per amplifier pair (pins 1/2SHDN and 3/4SHDN).
It is fully specified at both 3 V and 5 V single-supply operation, with input bias current ≤5 nA, PSRR of 106 dB, and CMRR of 80 dB (typ) - making it suitable for high-accuracy, low-noise amplification where supply rejection and common-mode immunity are critical in noisy embedded environments.
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/5 V system rails without level-shifting. |
| Gain-Bandwidth Product | 220 kHz - supports stable amplification of DC–200 kHz signals (e.g., ECG, temperature, pressure sensor outputs) with minimal phase lag. |
| Supply Current per Channel | 23 µA - allows continuous operation of all four op-amps for >1 year on a single CR2032 battery in sleep-aware systems. |
| Input Offset Voltage (typ) | 20 µV - ensures <0.2 mV error in 100× gain stages used in precision instrumentation amplifiers. |
| Output Drive Capability | ±10 mA - drives 500 Ω loads directly (e.g., ADC reference buffers, active filters) without external boost stages. |
| Shutdown Current (per ch) | 16 nA - reduces total quiescent draw to <65 nA when all four channels are disabled, ideal for wake-on-event architectures. |
| Rail-to-Rail I/O | Yes - preserves full dynamic range in 3 V systems, maximizing SNR when interfacing with 12-bit+ SAR ADCs. |
Pinout & Package
TSSOP-16 package (4.4 mm × 5.0 mm, 0.65 mm pitch), thermally enhanced for sustained operation at 125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUT (Ch 1–4) | Amplifier output terminals - each capable of sourcing/sinking ±10 mA while maintaining rail-to-rail swing. |
| 2, 6, 10, 14 | IN− (Ch 1–4) | Inverting inputs - CMOS-based, with input bias current ≤5 nA and common-mode range from GND to VDD. |
| 3, 7, 11, 15 | IN+ (Ch 1–4) | Non-inverting inputs - identical specs to IN−; supports true rail-to-rail differential input operation. |
| 4, 12 | GND | Analog ground reference - dual ground pins reduce ground bounce in multi-channel switching applications. |
| 8 | VDD+ | Positive supply - accepts 2.7–6 V; decoupling capacitor required within 1 cm for stability at full bandwidth. |
| 16 | NC | No internal connection - left unconnected; not usable as thermal pad or auxiliary terminal. |
| 1/2SHDN (Pin 11) | Shutdown Enable (Ch 1 & 2) | Active-high control - pulls outputs to high-Z and cuts channel current to 16 nA when driven ≥2 V (at VDD = 5 V). |
| 3/4SHDN (Pin 15) | Shutdown Enable (Ch 3 & 4) | Independent active-high control - enables selective power gating of amplifier pairs without affecting others. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3 V supply headroom - critical for maximizing resolution in low-voltage data acquisition systems. |
| Ultralow 23 µA/channel supply current | Reduces thermal load and extends battery life in always-on wearable health monitors and IoT edge nodes. |
| Independent dual shutdown controls | Allows dynamic power partitioning - e.g., keep Ch 1–2 active for sensor polling while shutting down Ch 3–4 during idle cycles. |
| Guaranteed operation from −40°C to 125°C | Validates use in automotive cabin modules, industrial motor controllers, and outdoor environmental sensors without derating. |
| 220 kHz GBW with 0.11 V/µs slew rate | Supports accurate amplification of slow-moving physiological and industrial process signals without distortion or settling delay. |

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 die, TSSOP-16 package without tape-and-reel suffix; identical electrical specs and pinout. | No functional difference - differs only in packaging format (bulk vs. reel); same thermal and electrical behavior. | Select TLV2455IPW for manual prototyping or low-volume assembly; TLV2455IDR is preferred for automated SMT production. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower noise (5.5 nV/√Hz), but higher supply current (17 µA/ch for dual version; no quad variant). | Lacks quad configuration and shutdown - requires two duals to match channel count, increasing board area and BOM count. | Choose OPA2333PWR only when microvolt-level drift over temperature is mandatory; TLV2455IDR remains optimal for cost-sensitive, space-constrained quad designs with shutdown. |
Compared with TLV2455IPW, TLV2455IDR offers identical performance in a tape-and-reel format for SMT line compatibility; versus OPA2333PWR, TLV2455IDR provides integrated quad + shutdown in one TSSOP-16 package, reducing component count and layout complexity for portable instrumentation.

FAQ
What is the operating temperature range for TLV2455IDR?
The TLV2455IDR is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, supply current, and gain-bandwidth product - ensuring reliability in harsh environments without derating.
Does TLV2455IDR support true rail-to-rail input and output?
Yes, TLV2455IDR supports rail-to-rail input (common-mode range from GND to VDD) and rail-to-rail output (swings within 250 mV of each rail at 2.5 mA load). This is confirmed in the datasheet's "Rail-To-Rail Input/Output (RRIO)" feature list and verified in Figures 1–2 (input offset vs. VIC) and Figures 11–14 (output voltage vs. load).
How does the shutdown function work on TLV2455IDR?
The TLV2455IDR has two independent shutdown pins: Pin 11 (1/2SHDN) disables Channels 1 and 2, and Pin 15 (3/4SHDN) disables Channels 3 and 4. When pulled high (≥2 V at VDD = 5 V), each pair enters shutdown with 16 nA/channel supply current and high-impedance outputs - enabling granular power control in multi-sensor systems.
What package type is used for TLV2455IDR?
TLV2455IDR uses the TSSOP-16 package (PW suffix), measuring 4.4 mm × 5.0 mm with 0.65 mm lead pitch. This is explicitly listed in the "TLV2454 and TLV2455 AVAILABLE OPTIONS" table and confirmed in the "TLV245x PACKAGE PINOUTS" diagram for D/N/PW packages.
Is TLV2455IDR pin-compatible with other TLV245x variants?
No - TLV2455IDR (quad, TSSOP-16) is not pin-compatible with TLV2450/1 (single, SOT-23), TLV2452/3 (dual, MSOP-8/10), or TLV2454 (quad, SOIC-14). Its 16-pin TSSOP layout with dual shutdown controls and dedicated ground pins is unique to the TLV2455 family member, as shown in the official pinout diagram on page 3 of the datasheet.
