Product details
Overview
TLV2475ID from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier with shutdown functionality, designed for low-power, high-precision signal conditioning in space-constrained systems. It delivers 2.8MHz gain-bandwidth, ±35mA output drive at 500mV from rails, 250μV typical input offset voltage, and consumes only 600μA per channel at 3–6V supply - ideal for portable medical sensors and battery-powered data acquisition.
For engineers reviewing the TLV2475ID datasheet, TLV2475ID pinout, TLV2475ID application, or TLV2475ID equivalent, key selection criteria include its I-suffix industrial temperature range (–40°C to +125°C), TSSOP-16 package with integrated shutdown control per pair, rail-to-rail swing under load, and ultra-low 1μA/channel shutdown current at 5V.
Technical Context
The TLV2475ID implements a CMOS input stage enabling 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD). Its output stage supports true rail-to-rail swing - delivering ±10mA within 180mV of each rail and ±35mA at 500mV off-rail - resolving classic micropower op-amp drive limitations.
Shutdown is implemented via two independent logic-controlled terminals (pins 1/2SHDN and 3/4SHDN), placing corresponding amplifier pairs into high-impedance output state while reducing supply current to ≤1000nA per channel at 5V. Phase margin remains stable (>61°) up to 1nF capacitive load when using recommended RNULL compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - enables stable unity-gain buffering and closed-loop amplification up to ~200kHz with 10x phase margin margin. |
| Supply current per channel | 600μA at 3–6V - allows continuous operation in 10-year battery-powered sensor nodes with sub-2.5mA total quiescent draw. |
| Shutdown current per channel | 1000nA at 5V - reduces system standby power to <4μA for all four channels, critical for wake-on-event architectures. |
| Output drive capability | ±35mA at 500mV from rail - directly drives ADC reference buffers, LED drivers, or 50Ω transmission lines without external boost stages. |
| Input offset voltage | 250μV (typ) - supports 12-bit accuracy in 3.3V systems without trimming, even after full industrial temperature cycling. |
| Rail-to-rail I/O | Full 0V to VDD input range and output swing - maximizes dynamic range in single-supply 3V systems, e.g., 0–3.3V sensor outputs. |
| Operating temperature | –40°C to +125°C - qualified for under-hood automotive, industrial motor control feedback, and outdoor IoT edge nodes. |
Pinout & Package
TSSOP-16 package (4.4mm × 5mm × 1.2mm height) with exposed thermal pad; RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | 1/2 Amplifier Shutdown Control | Active-low logic input; pulls corresponding pair (Ch1/Ch2) into high-Z output and sub-μA shutdown mode when <0.8V. |
| 3, 5, 7, 9 | Inverting Inputs (Ch1–Ch4) | High-impedance CMOS inputs accepting 0V to VDD common-mode range; 2.5pA bias current minimizes resistor-induced errors. |
| 4, 6, 8, 10 | Non-inverting Inputs (Ch1–Ch4) | Matched to inverting inputs; enables precision instrumentation configurations like difference amplifiers with <1μV/°C drift. |
| 11, 13, 14, 16 | Outputs (Ch1–Ch4) | Rail-to-rail capable; sustains ±10mA within 180mV of rails or ±35mA at 500mV - eliminates need for discrete output stage in most analog front-ends. |
| 12 | GND | Analog ground reference; requires low-impedance connection to minimize PSRR degradation and crosstalk between channels. |
| 15 | VDD | Single 2.7–6V supply input; internal regulation ensures stable biasing across voltage range; 1090mW max power dissipation at TA ≤+25°C. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 3.3V supply headroom in sensor signal chains, preserving >99% of ADC input range without level-shifting. |
| Independent dual-pair shutdown | Allows selective deactivation of Ch1/Ch2 or Ch3/Ch4 - e.g., keep one pair active for wake-up monitoring while shutting down others for ultra-low sleep current. |
| 2.8MHz GBW with 1.5V/μs slew rate | Supports accurate amplification of 100kHz sinusoidal signals with <0.1% THD+N at AV=10, suitable for ultrasound preamps and audio line drivers. |
| Low 250μV VIO and 0.4μV/°C drift | Reduces calibration frequency in precision weight scales and thermocouple amplifiers; maintains 12-bit linearity over full temperature range. |
| ±35mA output drive at 500mV from rail | Directly interfaces with SAR ADC reference buffers (e.g., REF5025) and drives 100Ω loads without external transistors or charge pumps. |

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 |
|---|---|---|---|
| TLV2475CDR | Same architecture and pinout, but C-suffix (0°C to +70°C) and tape-and-reel packaging; 350nA/ch shutdown current at 3V vs. 1000nA at 5V for TLV2475ID. | Targeted at commercial-grade consumer electronics where extended temperature range is unnecessary. | Select when cost sensitivity outweighs industrial temp requirement and board-level thermal management ensures <70°C operation. |
| OPA2333PWR | Zero-drift architecture; 0.02μV/°C offset drift vs. 0.4μV/°C; 17μV max VIO vs. 2400μV max for TLV2475ID; no shutdown function; SOIC-8 dual (requires two units for quad). | Better for DC-critical applications like precision weigh scales; unsuitable where shutdown or quad integration is mandatory. | Choose only if ultra-low drift dominates design priorities and layout area allows dual SOIC placement; not drop-in compatible. |
Compared with TLV2475CDR, TLV2475ID provides guaranteed operation to +125°C and higher shutdown current tolerance across voltage range; compared with OPA2333PWR, TLV2475ID offers integrated quad topology with shutdown but trades off drift performance for cost and power efficiency.

FAQ
What is the maximum capacitive load the TLV2475ID can drive without instability?
The TLV2475ID maintains ≥61° phase margin with up to 1nF load when using the recommended series RNULL compensation resistor (≥20Ω) at the output. Driving >10pF directly risks ringing or oscillation due to reduced loop stability; always insert RNULL between amplifier output and capacitive node per Figure 42 in the datasheet. This applies identically across all four channels of the TLV2475ID.
Does the TLV2475ID support true single-supply operation from 2.7V?
Yes, the TLV2475ID is fully specified for 2.7V to 6V single-supply operation. Its rail-to-rail input stage accepts common-mode voltages from 0V to VDD, and the output swings within 180mV of both rails under 10mA load - enabling full-scale signal handling in 2.7V systems like Li-ion powered IoT nodes. All key parameters including GBW, VIO, and IDD are guaranteed across this range for the TLV2475ID.
How does shutdown functionality work on the TLV2475ID?
The TLV2475ID features two independent shutdown pins: pin 1 (1/2SHDN) controls channels 1 and 2, while pin 2 (3/4SHDN) controls channels 3 and 4. Driving either pin below 0.8V disables the corresponding pair, forcing outputs into high-impedance state and reducing per-channel supply current to ≤1000nA at 5V. Both pins must be pulled high (>2V) to enable all four channels. This dual-control scheme is unique to the TLV2475ID among quad variants.
What is the thermal performance of the TLV2475ID in TSSOP-16 package?
The TLV2475ID in TSSOP-16 has θJA = 114.7°C/W and θJC = 25.7°C/W. At maximum rated dissipation of 1090mW (TA ≤+25°C), junction temperature rise is ~28°C above ambient - well within the +150°C absolute max. For continuous 125°C ambient operation, derating to ≤500mW total power is recommended. The exposed thermal pad must be soldered to PCB copper for optimal heat transfer in the TLV2475ID.
Can the TLV2475ID replace older TLV2465 or TLV2775 op-amps in existing designs?
The TLV2475ID is not a direct replacement for TLV2465 (higher drive, no shutdown) or TLV2775 (higher speed, no rail-to-rail input). While pin-compatible in TSSOP-16, key differences exist: TLV2475ID offers shutdown and rail-to-rail input but lower GBW (2.8MHz vs. 6.4MHz/5.1MHz) and higher VIO (250μV typ vs. 150μV/360μV). Verify stability, offset, and bandwidth margins before substitution in the TLV2475ID.
