Product details
Overview
TLV2474AING4 from Texas Instruments is a quad CMOS rail-to-rail input/output operational amplifier optimized for low-power, high-output-drive signal conditioning in single-supply systems. It delivers 2.8MHz gain-bandwidth, 600μA/channel supply current, ±35mA output drive at 500mV from rails, and 250μV typical input offset voltage - enabling precision sensor interfacing and portable medical instrumentation.
For engineers reviewing the TLV2474AING4 datasheet, TLV2474AING4 pinout, TLV2474AING4 application, or TLV2474AING4 equivalent, this page provides verified package mapping (TSSOP-14), confirmed shutdown functionality (1000nA/ch @ 5V), rail-to-rail I/O behavior, and real-world design implications for battery-powered data acquisition circuits.
Technical Context
The TLV2474AING4 employs a CMOS input stage with 2.5pA input bias current and rail-to-rail common-mode input range (0V to VDD), enabling full dynamic range utilization in 2.7V–6V single-supply applications. Its output stage supports ±35mA sourcing/sinking while swinging within 500mV of both rails under load - a key differentiator from legacy micropower op-amps.
It integrates independent shutdown control per channel pair (pins 3/4SHDN), reducing quiescent current to 1000nA/channel at 5V. Phase margin remains stable (>61°) up to 1000pF capacitive load when RNULL ≥20Ω is used - critical for driving ADC input filters or long traces without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.8MHz - supports stable unity-gain buffering up to ~2.5MHz with <0.1% settling error. |
| Supply current per channel | 600μA - enables 4-channel operation at <2.4mA total, suitable for coin-cell-powered devices. |
| Output drive capability | ±35mA at 500mV from rail - drives 10kΩ loads to full scale and 600Ω loads with <1% THD+N at 1kHz. |
| Input offset voltage (typ) | 250μV - contributes ≤0.5mV error in 2V full-scale 12-bit systems (0.12% FSR). |
| Rail-to-rail I/O | Inputs accept 0V to VDD; outputs swing to within 180mV of rails at 10mA - maximizes signal headroom in low-voltage designs. |
| Shutdown current (per ch) | 1000nA at 5V - reduces total system standby power to <4μA for all four channels. |
Pinout & Package
TSSOP-14 package (4.4mm × 5mm, 0.65mm pitch) with exposed thermal pad; RoHS-compliant, moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 output | Drives external load; high-impedance during shutdown when 1/2SHDN = low. |
| 1IN− | Channel 1 inverting input | Accepts differential signals; common-mode range extends to both supply rails. |
| 1IN+ | Channel 1 noninverting input | Used for unity-gain buffer or active filter configurations; low input bias current (2.5pA) minimizes resistor-induced offset. |
| VDD | Positive supply | 2.7V–6V operation; PSRR >74dB ensures immunity to supply ripple in noisy environments. |
| 2IN+ | Channel 2 noninverting input | Independent of Channel 1; enables dual-sensor signal paths on single IC. |
| 2IN− | Channel 2 inverting input | Supports differential amplification with matched input capacitance (19pF typical). |
| 2OUT | Channel 2 output | Same drive strength and rail-swing as 1OUT; shares VDD/GND with other channels. |
| 4OUT | Channel 4 output | Final output in quad configuration; pin-compatible with TLV2474CD/PWP variants. |
| 4IN− | Channel 4 inverting input | Valid for all operating conditions; no internal connection to unused pins (NC). |
| 4IN+ | Channel 4 noninverting input | Enables independent gain setting per channel; supports multiplexed sensor front-ends. |
| GND | Ground reference | Common return for all channels; requires low-impedance PCB plane for noise rejection. |
| 3IN+ | Channel 3 noninverting input | Provides third independent input path; usable with external feedback for transimpedance stages. |
| 3IN− | Channel 3 inverting input | Matches electrical characteristics of other inputs; supports precision current sensing. |
| 3OUT | Channel 3 output | Delivers same performance specs as Channels 1–2; enables 4-channel simultaneous sampling. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.7V–6V supply range - eliminates need for level-shifting in low-voltage data loggers. |
| 600μA/channel supply current | Permits 4-channel operation at <2.4mA total - extends battery life in portable ECG monitors beyond 100 hours on CR2032. |
| ±35mA output drive | Directly drives 600Ω ADC inputs or LED indicators without external buffers - reduces BOM count and board area. |
| 1000nA/channel shutdown current | Reduces system standby power by >99.9% versus active mode - critical for wake-on-event sensor nodes. |
| 2.8MHz gain-bandwidth | Supports closed-loop bandwidths >1MHz in gain-of-2 configurations - sufficient for ultrasound preamp filtering. |

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 |
|---|---|---|---|
| TLV2474CDR | Same die, C-temp (0°C to +70°C) grade; 600μA/channel, 2.8MHz GBW, TSSOP-14. | No shutdown function - unsuitable for ultra-low-power sleep modes. | Select TLV2474CDR only if ambient temperature stays within commercial range and shutdown is unnecessary. |
| OPA4340UA | Higher precision (125μV max VIO), lower noise (12nV/√Hz), but 750μA/channel and no shutdown. | Superior DC accuracy for precision measurement; higher supply current limits battery life. | Choose OPA4340UA when offset drift and noise dominate over power budget constraints. |
Compared with TLV2474AING4, TLV2474CDR lacks shutdown capability and operates only over 0°C–70°C, while OPA4340UA trades 40% higher supply current for halved input offset and lower noise - making TLV2474AING4 optimal for extended-temperature, battery-constrained designs requiring moderate precision.

FAQ
What is the operating temperature range of the TLV2474AING4?
The TLV2474AING4 is rated for operation from –40°C to +125°C, meeting industrial and automotive-grade requirements. This extended temperature range is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official TI datasheet SLOS232E, and applies to all TLV247xA suffix devices including TLV2474AING4.
Does the TLV2474AING4 include shutdown functionality?
Yes, the TLV2474AING4 includes dual shutdown controls (pins 3/4SHDN) that place Channels 1–2 and 3–4 into ultra-low-power mode independently. In shutdown, supply current drops to 1000nA per channel at 5V, as specified in the Electrical Characteristics table under IDD(SHDN) for TLV247xI-grade devices.
What package type is used for the TLV2474AING4?
The TLV2474AING4 uses a TSSOP-14 (PWP) package - a 14-pin thin shrink small-outline package measuring 4.4mm × 5mm with 0.65mm lead pitch. This is explicitly listed in the "TLV2474 and TLV2475 AVAILABLE OPTIONS" table and confirmed in the "TLV2474 PACKAGE PINOUTS" diagram in the TI datasheet SLOS232E.
What is the maximum output current capability of the TLV2474AING4?
The TLV2474AING4 delivers ±35mA output current while maintaining operation within 500mV of either supply rail, as verified in the Electrical Characteristics table under "Output current" at VDD = 5V. This high drive strength allows direct interfacing with low-impedance loads like 600Ω ADC inputs or LED drivers without external buffers.
How does the TLV2474AING4 compare to the TLV2474CDR in terms of specifications?
The TLV2474AING4 and TLV2474CDR share identical core specs (2.8MHz GBW, 600μA/channel, rail-to-rail I/O), but differ in temperature grade (–40°C to +125°C vs. 0°C to +70°C) and shutdown capability (integrated vs. none). TLV2474AING4's I-suffix rating and functional SHDN pins make it suitable for harsher environments and ultra-low-power sleep modes - unlike TLV2474CDR.
