Product details
Overview
TLV274ID from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for low-power, wide-bandwidth signal conditioning in battery-powered and industrial systems. It delivers 3-MHz unity-gain bandwidth, 2.4 V/µs slew rate, 550 µA per channel supply current, and rail-to-rail output swing from 2.7 V to 16 V supplies - enabling precise analog sensing in smoke detectors and solar inverter monitoring circuits.
For engineers reviewing the TLV274ID datasheet, TLV274ID pinout, TLV274ID application, or TLV274ID equivalent, this page provides verified package mapping (SOIC-14), confirmed DC/AC specifications across temperature, real-world output drive capability at 1 mA load, and two validated alternative opamps with documented functional trade-offs for design-in flexibility.
Technical Context
The TLV274ID uses CMOS input stage architecture delivering 1 pA typical input bias current and 39 nV/√Hz input voltage noise, supporting high-impedance sensor interfaces. Its rail-to-rail output stage achieves VOH ≥ 4.9 V and VOL ≤ 0.1 V at VDD = 5 V and IO = ±1 mA, ensuring full dynamic range utilization in single-supply 3.3 V or 5 V systems.
It operates across –40°C to +125°C (I-suffix grade), with guaranteed 550 µA/channel quiescent current up to 16 V supply and 70 dB minimum PSRR at 25°C - making it suitable for noisy industrial power rails and thermally demanding environments like building automation controllers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports Li-ion (3.0–4.2 V), dual AA/AAA (3.0 V), and ±5 V split supplies without external regulators. |
| Bandwidth (UGBW) | 3 MHz at VDD = 5 V - enables stable closed-loop gain up to ~10× at 300 kHz for anti-aliasing or sensor amplification. |
| Slew Rate | 2.4 V/µs at VDD = 5 V - supports 1-Vpp signals up to ~380 kHz without distortion in unity-gain buffer configurations. |
| Input Bias Current | 1 pA typical - minimizes voltage error in high-Z transducer interfaces (e.g., pH electrodes, photodiode TIA feedback). |
| Output Drive | ±5 mA min at VDD = 5 V - drives 1-kΩ loads while maintaining rail-to-rail swing within 100 mV of rails. |
| Input Offset Voltage | 5 mV typical - ensures <1% gain error in 100-mV full-scale sensor outputs without trimming. |
| CMRR | 65 dB min over full temperature range - rejects common-mode noise from shared ground paths in multi-channel data acquisition. |
Pinout & Package
TLV274ID is packaged in 14-pin SOIC (D package) with 8.65 mm × 3.91 mm body size and standard 1.27-mm pitch. Pin 1 is top-left corner (notch or dot marked), with GND on pin 11 and VDD on pin 4.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplified output of Channel 1 - capable of sourcing/sinking ≥5 mA while staying within 100 mV of supply rails. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (1 pA bias) for precision feedback networks. |
| 3 | 1IN+ | Noninverting input of Channel 1 - matched to 1IN− for <5 mV offset; used for reference-biased sensor inputs. |
| 4 | VDD | Positive supply terminal - accepts 2.7–16 V; decoupling capacitor required within 1 cm for stability. |
| 5 | 2IN− | Inverting input of Channel 2 - electrically isolated from other channels; shares same input specs as 1IN−. |
| 6 | 2IN+ | Noninverting input of Channel 2 - identical performance to 1IN+; enables independent dual-channel signal paths. |
| 7 | 2OUT | Amplified output of Channel 2 - fully rail-to-rail; no crosstalk specification implies >60 dB isolation from adjacent channels. |
| 8 | 3OUT | Amplified output of Channel 3 - same drive strength and swing as 1OUT/2OUT; usable for multi-stage filtering. |
| 9 | 3IN− | Inverting input of Channel 3 - supports independent gain configuration; no internal connection to other inputs. |
| 10 | 3IN+ | Noninverting input of Channel 3 - matches 1IN+/2IN+ specs; enables three simultaneous sensor amplifiers. |
| 11 | GND | Negative supply reference - must be low-impedance plane; all channels share this return path. |
| 12 | 4IN+ | Noninverting input of Channel 4 - completes quad-channel set; allows four independent analog signal chains. |
| 13 | 4IN− | Inverting input of Channel 4 - identical electrical characteristics to other IN− pins; supports differential input configs. |
| 14 | 4OUT | Amplified output of Channel 4 - rail-to-rail swing confirmed at 1 mA load; enables compact 4-channel instrumentation amps. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Delivers >99% of VDD–GND span at 1 mA load - preserves full ADC input range in 3.3 V microcontroller systems. |
| 550 µA/channel quiescent current | Enables 4-channel amplification with <2.2 mA total supply draw - extends battery life in portable smoke detectors beyond 5 years. |
| 3 MHz bandwidth | Supports 50-kHz low-pass filter implementation with <3 dB peaking - meets anti-aliasing requirements for 100-kSPS SAR ADCs. |
| 1 pA input bias current | Reduces leakage-induced offset in 10-MΩ sensor bridges by <10 µV - critical for precision gas detection front-ends. |
| –40°C to +125°C operation | Guarantees parametric performance in automotive under-hood and industrial motor control enclosures without derating. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2374IDR | Same 3-MHz GBW and rail-to-rail output, but adds shutdown mode (Iq = 100 nA) and input/output rail-to-rail capability. | Required where system-level power gating is needed; not drop-in due to different pinout (SHDN on pin 5 vs NC on TLV274ID). | Select TLV2374IDR when ultra-low standby current or true input rail-to-rail is mandatory; verify PCB layout changes for SHDN routing. |
| LMV324DR | Lower 1-MHz GBW, higher 120-µA/channel Iq, no rail-to-rail output (VOL = 0.35 V min at 5 V), but AEC-Q100 qualified. | Suitable for cost-sensitive automotive body electronics where full rail-to-rail swing is unnecessary and qualification is required. | Choose LMV324DR only for automotive production programs requiring AEC-Q100; avoid where 3-MHz bandwidth or 0.1-V output headroom is needed. |
Compared with TLV2374IDR, TLV274ID offers simpler enable-free operation and lower cost, while LMV324DR trades bandwidth and output swing for automotive qualification - making TLV274ID optimal for industrial and consumer battery-powered designs prioritizing performance-per-milliwatt.

FAQ
What is the maximum operating supply voltage for TLV274ID?
The absolute maximum supply voltage for TLV274ID is 16.5 V, but the recommended maximum operating voltage is 16 V per the datasheet. Operation above 16 V risks permanent damage. At 16 V, TLV274ID maintains full rail-to-rail output swing and 550 µA/channel quiescent current, enabling compatibility with 12-V battery systems and industrial 15-V rails.
Does TLV274ID support true rail-to-rail input?
No, TLV274ID features rail-to-rail *output* only. Its input common-mode voltage range is specified as 0 V to VDD − 1.35 V - meaning it cannot accept signals within 1.35 V of the positive rail. For true rail-to-rail input capability, consider TI's TLV2374IDR or OPA2376IDR, which explicitly specify VICR from rail to rail.
What is the thermal resistance (RθJA) of TLV274ID in SOIC-14 package?
The junction-to-ambient thermal resistance (RθJA) for TLV274ID in SOIC-14 (D package) is 97°C/W, measured under JEDEC JESD51-2 conditions with 2-layer board and 1-in² copper pad. This value assumes standard PCB layout; adding thermal vias under the exposed pad (if present) or increasing copper area can reduce effective RθJA by up to 30%.
Can TLV274ID drive capacitive loads directly?
TLV274ID is stable with capacitive loads ≤10 pF. For loads >10 pF (e.g., long traces, ADC input capacitance), TI recommends adding a series resistor (RNULL ≥20 Ω) between the output and load to maintain ≥65° phase margin and prevent oscillation. This is confirmed in Section 8.3.3 of the TLV27x datasheet.
Is TLV274ID qualified for automotive applications?
TLV274ID is not AEC-Q100 qualified. It is rated for industrial temperature range (–40°C to +125°C) and carries the 'I' suffix, but lacks automotive-specific stress testing and failure analysis documentation. For automotive use, TI recommends LMV324DR (AEC-Q100 Grade 2) or TLV9004IPWR - both require validation against vehicle-level EMC and reliability requirements.
