Product details
Overview
TLV274IDRG4 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 gain-bandwidth, 2.4 V/µs slew rate, 550 µA/channel supply current, and operates from 2.7 V to 16 V across –40°C to +125°C. It serves as a precision analog front-end in sensor interfaces and power monitoring circuits.
For engineers reviewing the TLV274IDRG4 datasheet, TLV274IDRG4 pinout, TLV274IDRG4 application, or TLV274IDRG4 equivalent, key selection criteria include rail-to-rail output swing at low supply voltage, ultra-low input bias current (1 pA), input noise voltage (39 nV/√Hz), and compatibility with Li-ion and MSP430-based systems.
Technical Context
The TLV274IDRG4 uses CMOS input stage architecture enabling high-impedance sensor interfacing and low input bias current (1 pA typ). Its rail-to-rail output stage supports full dynamic range utilization down to 2.7-V single supply or ±1.35-V split supply.
It achieves 3-MHz unity-gain bandwidth with only 550 µA per channel, maintaining phase margin ≥65° into 10-pF capacitive loads. The device is fully specified for operation across –40°C to +125°C with input offset voltage of 5 mV (typ) and 7 mV (max) over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-supply Li-ion (3.0–4.2 V), dual-cell alkaline, and industrial ±5 V rails. |
| Gain-Bandwidth Product | 3 MHz (typ at VDD = 5 V) - enables stable closed-loop operation up to ~200 kHz in unity-gain buffer or gain-of-10 configurations. |
| Slew Rate | 2.4 V/µs (typ at VDD = 5 V) - supports clean 100-kHz sine-wave output at 2-Vpp without distortion. |
| Input Bias Current | 1 pA (typ at 25°C) - minimizes voltage error in high-Z sensor bridges and photodiode transimpedance stages. |
| Input Noise Voltage | 39 nV/√Hz (typ at 1 kHz) - suitable for precision DC-coupled amplification of microvolt-level signals. |
| Rail-to-Rail Output | Swings within 135 mV of each rail (at 1-mA load) - preserves >95% of available output dynamic range at 3-V supply. |
| Quiescent Current | 550 µA per channel (typ at VDD = 5 V) - enables four-channel amplification in sub-3-mA total system analog budget. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274IPW | TSSOP-14 package (5.00 mm × 4.40 mm); higher RθJA (135°C/W) vs SOIC (97°C/W); identical electrical specs. | Better suited for space-constrained PCBs where thermal margin allows; not drop-in compatible due to different footprint and soldering profile. | Select TLV274IPW only when board area is critical and thermal design accommodates higher junction temperature rise. |
| TLV2464CDR | Lower GBW (6.4 MHz), higher supply current (550 µA), rail-to-rail input/output, but higher input bias current (1300 pA) and noise (28 nV/√Hz). | Preferred where faster settling or rail-to-rail input is required, but unsuitable for ultra-high-Z sensor interfaces due to 1300-pA bias. | Choose TLV2464CDR only when input rail-to-rail operation is mandatory and sensor impedance is <1 MΩ. |
Compared with TLV274IPW and TLV2464CDR, TLV274IDRG4 offers superior thermal performance in SOIC packaging and unmatched 1-pA input bias for high-impedance precision applications - making it the optimal choice for battery-powered instrumentation and industrial sensor conditioning where leakage and power are critical.

FAQ
What is the maximum operating supply voltage for TLV274IDRG4?
The absolute maximum supply voltage for TLV274IDRG4 is 16.5 V, but the recommended maximum operating voltage is 16 V. Operation beyond this may cause permanent damage. At 16 V, the device maintains full rail-to-rail output swing and specified AC performance across –40°C to +125°C, supporting legacy 12-V and emerging high-voltage battery systems.
Does TLV274IDRG4 support rail-to-rail input?
No, TLV274IDRG4 features rail-to-rail output only - its input common-mode voltage range is 0 V to VDD − 1.35 V. It does not accept signals at the negative rail (GND) or within 1.35 V of the positive rail. For true rail-to-rail input capability, consider TI's TLV2464 or TLV2374 families, which trade higher input bias current for full input range.
What is the input offset voltage specification for TLV274IDRG4?
The TLV274IDRG4 has a typical input offset voltage of 5 mV at 25°C, with a maximum of 7 mV over the full industrial temperature range (–40°C to +125°C). This value is measured under standard conditions (VDD = 2.7 V/5 V/±5 V, RL = 10 kΩ, VO = VDD/2). It remains stable across supply voltages and is unaffected by rail-to-rail output operation.
Can TLV274IDRG4 drive capacitive loads directly?
TLV274IDRG4 can drive ≤10 pF capacitive loads stably. 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 preserve phase margin ≥65° and prevent ringing. This isolation technique is validated in the datasheet Figure 26 and maintains stability without degrading DC accuracy.
Is TLV274IDRG4 pin-compatible with other TLV27x variants?
TLV274IDRG4 (SOIC-14) is pin-compatible with other TLV274 variants in the same package - including TLV274IDR and TLV274IPWG4 - but not with TLV271 (SOT-23-5), TLV272 (MSOP-8/SOIC-8), or different-package TLV274 versions (e.g., TSSOP-14 TLV274IPW). Pin functions match exactly across SOIC-14 TLV274 devices, enabling direct substitution within the same footprint.
