Product details
Overview
TLV274IDG4 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, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across –40°C to +125°C. It is used in smoke detectors and solar inverters where precision, low quiescent power, and rail-to-rail swing are critical.
For engineers reviewing the TLV274IDG4 datasheet, TLV274IDG4 pinout, TLV274IDG4 application, or TLV274IDG4 equivalent, key selection criteria include guaranteed rail-to-rail output swing at 2.7 V, ultra-low 1 pA input bias current for high-impedance sensor interfaces, thermal performance in SOIC-14 (RθJA = 97°C/W), and compatibility with Li-ion and MSP430-based systems.
Technical Context
The TLV274IDG4 employs a CMOS input stage enabling femtoampere-level input bias current and high input impedance, making it suitable for photodiode amplification and capacitive sensor front-ends. Its rail-to-rail output stage uses complementary push-pull architecture to achieve <100 mV saturation voltage near both rails under 1 mA load.
It is fully specified for single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) operation, with common-mode input range extending from GND to VDD – 1.35 V. DC precision includes 5 mV typical input offset voltage and 70 dB minimum CMRR at 2.7 V, supporting accurate low-voltage signal amplification without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 3 MHz unity-gain bandwidth enables stable amplification of audio and control-loop signals up to ~200 kHz with phase margin >65°. |
| Slew Rate | 2.4 V/µs supports clean 100-kHz, 2-VPP sine wave reproduction without distortion in unity-gain buffer configurations. |
| Supply Current | 550 µA per channel allows four independent amplifiers to operate within 2.2 mA total, ideal for always-on sensor nodes. |
| Input Bias Current | 1 pA typical enables direct connection to >100 MΩ source impedances (e.g., piezoelectric sensors) without significant DC error. |
| Rail-to-Rail Output | Swings within 100 mV of VDD and GND at 1 mA load, maximizing dynamic range in 3.3-V or 5-V microcontroller ADC interfaces. |
| Input Noise | 39 nV/√Hz at 1 kHz sets floor for sub-10 µV RMS noise in 10-kHz bandwidth applications like precision instrumentation. |
| Operating Temp | –40°C to +125°C industrial grade rating ensures reliability in automotive cabin modules and solar inverter control boards. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274CDR | Commercial-grade (0°C to 70°C); otherwise identical electrical specs and pinout. | Not qualified for industrial or automotive ambient conditions; unsuitable for outdoor or engine-compartment use. | Select TLV274IDG4 when operating temperature exceeds 70°C or long-term reliability at temperature extremes is required. |
| TLV2464CDR | Lower bandwidth (6.4 MHz), higher supply current (550 µA), rail-to-rail input/output, but 1300 pA IIB. | Better for higher-speed applications but unsuitable for ultra-high-impedance sources due to 1300× higher input bias current. | Choose TLV274IDG4 when interfacing with photodiodes, pH electrodes, or MEMS sensors requiring sub-pA bias current. |
Compared with TLV274CDR, TLV274IDG4 provides extended temperature qualification essential for industrial deployments; compared with TLV2464CDR, it offers 1300× lower input bias current critical for precision sensor front-ends-making TLV274IDG4 the optimal choice for high-impedance, wide-temperature, low-power analog signal chains.

FAQ
What is the maximum supply voltage for TLV274IDG4?
The absolute maximum supply voltage for TLV274IDG4 is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Operation above 16 V risks permanent damage. At 16 V, the device maintains full rail-to-rail output swing and 3-MHz bandwidth, making it suitable for 12-V battery systems with transient headroom.
Does TLV274IDG4 support rail-to-rail input?
No, TLV274IDG4 features rail-to-rail output only. Its common-mode input voltage range extends from GND 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 TLV2374 or OPA333 families instead.
What is the thermal resistance of TLV274IDG4 in SOIC-14 package?
TLV274IDG4 in SOIC-14 (D package) has a junction-to-ambient thermal resistance (RθJA) of 97°C/W under standard JEDEC test conditions. This value assumes a 2-layer PCB with 1-in² copper pour; actual board layout can reduce thermal resistance significantly with internal ground planes and thermal vias.
Can TLV274IDG4 drive capacitive loads directly?
TLV274IDG4 becomes unstable with capacitive loads >10 pF due to reduced phase margin. TI recommends adding a series resistor (RNULL ≥ 20 Ω) between the output pin and the capacitive load to restore stability. This is critical for driving ADC input capacitors or long cables in sensor applications.
Is TLV274IDG4 pin-compatible with other TLV27x variants?
Yes, TLV274IDG4 shares identical pinout with all TLV274 variants in SOIC-14 (e.g., TLV274CDR, TLV274IPW), including TLV274IDR. Pin compatibility extends across temperature grades and packaging options (SOIC, TSSOP, PDIP), enabling seamless substitution without PCB redesign.
