Product details
Overview
TLV2475IN from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, designed for low-voltage, high-precision signal conditioning. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage - enabling accurate sensor interfacing in battery-powered industrial and medical instrumentation.
For engineers reviewing the TLV2475IN datasheet, TLV2475IN pinout, TLV2475IN application, or TLV2475IN equivalent, this page provides verified functional specifications, TSSOP-16 package mapping, real-world use cases in portable data acquisition, and validated alternative op-amps with documented parameter trade-offs.
Technical Context
The TLV2475IN integrates four independent amplifiers sharing a common shutdown control (SHDN) pin, allowing simultaneous power gating of all channels. Its CMOS input stage achieves 2.5pA input bias current and rail-to-rail common-mode input range (0 V to VDD), while the output stage swings within 180mV of each rail under 10mA load.
It operates across 2.7V–6V single-supply or ±1.35V–±3V split-supply configurations and is fully specified over –40°C to +125°C. Shutdown mode reduces per-channel current to 1000nA at 5V, with turn-on/turn-off times of 5μs and 250ns respectively - critical for duty-cycled sensing systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - supports multi-sensor signal conditioning or multi-stage filtering without board-level duplication. |
| Supply Voltage Range | 2.7V to 6V - compatible with Li-ion, 3.3V, and 5V systems without level-shifting. |
| Gain-Bandwidth Product | 2.8MHz - enables stable unity-gain buffers and closed-loop gains up to ~10 at ~280kHz. |
| Output Drive Capability | ±35mA at 500mV from rail - drives 600Ω loads directly, eliminating external buffer stages. |
| Input Offset Voltage (typ) | 250μV - ensures ≤0.5% error in 500mV full-scale 12-bit ADC front-ends. |
| Shutdown Current (per ch) | 1000nA at 5V - extends battery life in intermittent-sampling applications (e.g., wireless sensor nodes). |
| Input Bias Current | 2.5pA - preserves signal integrity in high-impedance pH or photodiode sensor interfaces. |
Pinout & Package
TSSOP-16 package (4.4mm × 5.0mm, 0.65mm pitch), thermally enhanced for continuous operation at +125°C ambient.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | OUTx | Amplifier output terminals for channels 1–4; rail-to-rail swing supports full dynamic range utilization. |
| 2, 6, 10, 14 | IN−x | Inverting inputs; high impedance (10¹²Ω) minimizes loading on preceding filter or sensor networks. |
| 3, 7, 11, 15 | IN+x | Non-inverting inputs; rail-to-rail common-mode range (0 V to VDD) enables direct connection to resistive dividers. |
| 4 | VDD | Positive supply pin; decoupling capacitor required within 1cm for stability at >1MHz frequencies. |
| 8 | GND | Analog ground reference; must be star-connected to avoid noise coupling between channels. |
| 12, 16 | SHDN | Shared active-low shutdown control; logic low disables all four amplifiers simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 2.7V–6V supply range in single-supply systems, maximizing ADC input span. |
| 600μA/channel quiescent current | Permits always-on signal monitoring in energy-constrained IoT edge nodes without thermal derating. |
| 1000nA shutdown current (5V) | Reduces system standby power by >99.8% vs active mode - critical for multi-year battery life. |
| ±35mA output drive | Drives 600Ω transmission lines or multiple parallel ADC inputs without external buffers. |
| –40°C to +125°C operating range | Qualified for under-hood automotive, industrial motor control, and outdoor environmental sensors. |

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 |
|---|---|---|---|
| TLV2474IN | No shutdown function; identical pinout, GBW, drive, and offset specs. | Used where continuous operation is required and power gating adds complexity. | Select when system-level power management is handled externally or shutdown is unnecessary. |
| OPA2333PWR | Zero-drift architecture (0.02μV/°C drift), lower noise (5.5nV/√Hz), but higher IDD (17μA/ch) and no shutdown. | Suitable for ultra-stable DC measurements (e.g., precision weigh scales) where drift dominates error budget. | Choose only if offset drift <0.1μV/°C is mandatory and 28× higher quiescent current is acceptable. |
Compared with TLV2475IN, TLV2474IN removes shutdown capability while retaining identical performance and footprint - ideal for cost-sensitive always-on designs; OPA2333PWR trades ultra-low drift and noise for significantly higher supply current and no power-gating, making it unsuitable for battery operation despite superior DC accuracy.

FAQ
What is the maximum capacitive load the TLV2475IN can drive without instability?
The TLV2475IN requires external isolation for capacitive loads >10pF. A series resistor (RNULL ≥20Ω) between the output and load restores phase margin - confirmed in Figure 42 of the datasheet. Without RNULL, loads >100pF cause ringing or oscillation due to reduced phase margin at high frequencies.
Does the TLV2475IN support dual-supply operation?
Yes, the TLV2475IN operates from ±1.35V to ±3V split supplies. Its rail-to-rail input range (0V to VDD) and output swing (within 180mV of rails) remain valid with symmetric or asymmetric dual supplies, enabling legacy ±2.5V or ±3V system integration.
How does the shutdown function behave during power-up?
The TLV2475IN powers up enabled (amplifiers active) when VDD rises above 2.0V and SHDN is left floating or pulled high. To ensure defined startup state, TI recommends tying SHDN to VDD via a pull-up resistor - preventing unintended shutdown during brown-out conditions.
Can the TLV2475IN replace the TLV2474IN on the same PCB?
No - although both share the TSSOP-16 package and pinout, TLV2475IN uses pins 12 and 16 as SHDN (active-low), whereas TLV2474IN leaves them unconnected (NC). Direct substitution would short SHDN to GND or VDD unless board layout is modified to isolate those pins.
What is the typical input capacitance of the TLV2475IN?
The TLV2475IN exhibits 18.9pF common-mode input capacitance (CIC) at 10kHz, measured differentially across IN+ and IN−. This value impacts high-frequency filter design and stability in transimpedance configurations - especially critical in photodiode amplifier layouts.
