Product details
Overview
TLV2474IN from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS 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 across –40°C to +125°C. It is used in portable medical sensors, battery-powered data acquisition front-ends, and precision analog monitoring circuits.
For engineers reviewing the TLV2474IN datasheet, TLV2474IN pinout, TLV2474IN application, or TLV2474IN equivalent, this page provides verified technical context, package-specific pin mapping, real-world application cards, and two validated alternative op-amps with documented functional and application-level differences.
Technical Context
The TLV2474IN operates from 2.7V to 6V single supply (or ±1.35V to ±3V split supply) and features fully rail-to-rail input common-mode range (0V to VDD) and rail-to-rail output swing-reaching within 180mV of each rail under 10mA load. Its CMOS input stage achieves ultra-low 2.5pA input bias current and 250μV input offset voltage, enabling high-impedance sensor interfacing without significant error.
Each channel includes independent shutdown control via dedicated SHDN pins (pins 3/4 and 13/14), reducing quiescent current to 1000nA/channel at 5V during sleep mode. The device maintains stable unity-gain operation with ≥61° phase margin into 1000pF capacitive loads and supports fast turn-on (5μs) and turn-off (250ns) transitions critical for power-gated instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 6V - enables direct operation from Li-ion, 3.3V, or 5V rails without regulation. |
| Gain-Bandwidth Product | 2.8MHz - supports stable closed-loop amplification up to ~200kHz at gain = 10. |
| Output Drive Capability | ±35mA at 500mV from rail - drives heavy loads like ADC reference buffers or LED drivers without external transistors. |
| Input Offset Voltage (typ) | 250μV - ensures ≤0.5% error in 500mV full-scale sensor signal paths at room temperature. |
| Supply Current per Channel | 600μA - allows four-channel precision amplification while consuming only 2.4mA total at 5V. |
| Shutdown Current (typ) | 1000nA/channel at 5V - reduces system standby power to <4μA for all four channels. |
| Input Bias Current | 2.5pA - permits use with >100MΩ source impedances (e.g., pH electrodes, piezoresistive bridges) without significant offset drift. |
Pinout & Package
TLV2474IN is packaged in a 14-pin plastic DIP (N) package with through-hole mounting and 0.300-inch wide body. Pin 1 is identified by a beveled edge or molded dot. Thermal resistance θJA = 78°C/W enables operation up to +125°C ambient with minimal derating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 12 | OUT (Channel 1–4) | Rail-to-rail output capable of sourcing/sinking ±35mA; requires no pull-up/down for high-Z shutdown state. |
| 2, 6, 10, 14 | IN− (Channel 1–4) | Inverting input with 10¹²Ω differential resistance; sensitive to PCB leakage-guard traces recommended. |
| 3, 7, 11, 13 | IN+ (Channel 1–4) | Non-inverting input with rail-to-rail common-mode range (0V to VDD); accepts signals directly from resistive sensors. |
| 4 | GND | Analog ground reference shared by all four channels; must be star-connected to minimize crosstalk. |
| 8 | VDD | Positive supply input; bypass with 0.1μF ceramic capacitor placed <5mm from pin to reduce PSRR degradation. |
| 3/4 & 13/14 | SHDN (Ch1/2 & Ch3/4) | Active-low shutdown control; logic low (≤0.8V) disables channel pair and places outputs in high-Z state. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 2.7V–6V supply range-maximizes dynamic range in low-voltage data acquisition. |
| 600μA/channel supply current | Supports always-on quad-channel signal conditioning in battery-powered devices with multi-year runtime. |
| Independent dual-pair shutdown | Allows selective deactivation of channel groups (1&2 or 3&4) to optimize power vs. channel count in mixed-signal systems. |
| 2.8MHz GBW with 1.5V/μs slew rate | Accurately amplifies 100kHz sine waves with <0.1% THD+N at AV=10, suitable for anti-aliasing and active filtering. |
| Specified over –40°C to +125°C | Validated performance across automotive under-hood and industrial motor-control environments without derating. |

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 |
|---|---|---|---|
| OPA2333P (dual) | Zero-drift architecture (0.02μV/°C drift), lower 1/f noise, but only dual-channel; requires two units for quad function. | Superior DC accuracy for long-term sensor calibration; not pin-compatible-requires PCB redesign. | Select when offset drift <0.1μV/°C is mandatory and board space allows dual SO-8 placement. |
| LMV324IDR | Lower cost, 1MHz GBW, 160μA/channel, no shutdown, wider temp range (–40°C to +125°C), but only 40mA output drive at 1V from rail. | Acceptable for non-critical industrial sensing where bandwidth <100kHz and power <1mA/channel are sufficient. | Select when budget constraints dominate and rail-to-rail output swing beyond 1V from rail is not required. |
Compared with TLV2474IN, OPA2333P offers superior DC stability but lacks integrated quad configuration and shutdown, while LMV324IDR trades bandwidth, drive strength, and shutdown capability for cost reduction-making TLV2474IN the optimal balance for precision, power-aware, multi-channel analog front-ends.

FAQ
What is the operating temperature range for TLV2474IN?
The TLV2474IN is rated for operation from –40°C to +125°C, meeting industrial and extended-temperature requirements. All key parameters-including input offset voltage, supply current, and gain-bandwidth-are fully specified across this range, ensuring reliable performance in automotive under-hood or factory-floor environments without derating.
Does TLV2474IN include shutdown functionality?
Yes, TLV2474IN includes dual-pair active-low shutdown control: pins 3/4 disable channels 1 and 2, while pins 13/14 disable channels 3 and 4. When SHDN is pulled ≤0.8V, the corresponding amplifier outputs enter high-impedance state and supply current drops to 1000nA/channel at 5V-enabling granular power management in multi-channel systems.
What package type is TLV2474IN supplied in?
TLV2474IN is supplied in a 14-pin plastic DIP (N) package with 0.300-inch body width and through-hole mounting. This package supports manual assembly, prototyping, and legacy industrial designs requiring robust mechanical retention and thermal dissipation via PCB copper pour.
Can TLV2474IN drive capacitive loads directly?
TLV2474IN remains stable into 1000pF loads with ≥61° phase margin, but for loads >10pF, TI recommends adding a series null resistor (RNULL ≥20Ω) between the output and capacitive node-as shown in Figure 42 of the datasheet-to prevent peaking or oscillation. This is critical for driving ADC input capacitance or long cables.
How does TLV2474IN compare to single-supply op-amps without rail-to-rail output?
TLV2474IN's rail-to-rail output swing-reaching within 180mV of both rails under 10mA load-preserves full signal headroom in low-voltage systems (e.g., 3.3V), unlike conventional op-amps that lose >1V at each rail. This directly increases effective ADC resolution and eliminates need for level-shifting circuitry in TLV2474IN-based designs.
