Product details
Overview
TLV274IPWRG4 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 operates from 2.7 V to 16 V - enabling use in Li-ion powered instrumentation and sensor interfaces requiring full dynamic range near supply rails.
For engineers reviewing the TLV274IPWRG4 datasheet, TLV274IPWRG4 pinout, TLV274IPWRG4 application, or TLV274IPWRG4 equivalent, key selection criteria include its rail-to-rail output swing (enabling >98% of supply voltage utilization), ultra-low 1 pA input bias current (critical for high-impedance sensor front-ends), and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV274IPWRG4 employs CMOS input stage architecture with rail-to-rail complementary output transistors, supporting single-supply operation down to 2.7 V while maintaining 3-MHz bandwidth and 2.4 V/µs slew rate. Its 1 pA typical input bias current and 39 nV/√Hz input voltage noise enable precision amplification of weak signals from photodiodes, thermopiles, or bridge sensors without significant DC error or AC degradation.
It features no internal shutdown function and operates in a single functional mode across its full supply range (2.7 V–16 V) and temperature range (–40°C to +125°C). The device exhibits 65° phase margin into 10 pF capacitive load and requires external series resistance (>20 Ω) when driving >10 pF loads to ensure stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 3 MHz at 5 V supply - supports audio and sensor signal conditioning up to ~200 kHz closed-loop gain-bandwidth product. |
| Slew Rate | 2.4 V/µs - enables clean 100-kHz, 2-Vpp sine wave reproduction without distortion. |
| Supply Current | 550 µA per channel - allows four independent amplifiers to operate on <2.2 mA total, ideal for multi-channel portable instruments. |
| Input Bias Current | 1 pA - minimizes voltage error in high-Z sensor interfaces (e.g., pH electrodes, piezoresistive bridges). |
| Rail-to-Rail Output | Swings within 150 mV of VDD and GND at 1 mA load - preserves >94% of full-scale dynamic range in 3.3-V systems. |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - ensures low-noise amplification for microvolt-level biopotential or strain gauge signals. |
| Operating Temperature | –40°C to +125°C - qualified for under-hood automotive, solar inverter control, and industrial motor drive feedback loops. |
Pinout & Package
TSSOP-14 package (PW), body size 5.00 mm × 4.40 mm, 0.65-mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Amplifier channel 1 output - drives external load or next-stage input; rail-to-rail swing capability critical for ADC driver applications. |
| 2 | 1IN− | Inverting input for channel 1 - connects to feedback network or sensor reference point in differential configurations. |
| 3 | 1IN+ | Noninverting input for channel 1 - accepts high-impedance sensor signal with minimal loading due to 1 pA bias current. |
| 4 | VDD | Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor close to pin to suppress high-frequency noise. |
| 5 | 2IN+ | Noninverting input for channel 2 - enables independent signal conditioning paths without crosstalk (typical crosstalk <–80 dB at 10 kHz). |
| 6 | 2IN− | Inverting input for channel 2 - used in active filter or transimpedance configurations requiring matched input impedance. |
| 7 | 2OUT | Amplifier channel 2 output - shares same rail-to-rail performance and thermal characteristics as channel 1. |
| 8 | 3OUT | Amplifier channel 3 output - provides third independent gain stage for multi-sensor systems or analog signal routing. |
| 9 | 3IN− | Inverting input for channel 3 - supports simultaneous processing of three sensor channels in compact space-constrained designs. |
| 10 | 3IN+ | Noninverting input for channel 3 - maintains identical DC and AC specifications across all four channels per datasheet test conditions. |
| 11 | GND | Ground reference - common return path for all four amplifiers; requires low-impedance PCB plane connection to minimize noise coupling. |
| 12 | 4IN+ | Noninverting input for channel 4 - enables fourth independent signal path without additional IC footprint or BOM line item. |
| 13 | 4IN− | Inverting input for channel 4 - supports fully differential or single-ended configurations with consistent 500 µV max input offset voltage. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274IPW | Same electrical specs and pinout; differs only in tape-and-reel packaging (no G4 suffix) and RoHS compliance marking. | No functional difference; suitable for identical applications including industrial temperature-grade designs. | Select TLV274IPW for standard RoHS-compliant production; TLV274IPWRG4 is functionally identical with G4 suffix indicating green packaging. |
| TLV2374IDR | Includes shutdown control (SHDN pin), 1.8-V min supply, but lower 1.2-MHz bandwidth and 1.2 V/µs slew rate. | Preferred where power gating is required between measurements; unsuitable for >100-kHz signal paths. | Choose TLV2374IDR only if active power-down is mandatory; otherwise TLV274IPWRG4 offers superior speed and output drive. |
Compared with TLV274IPW, TLV274IPWRG4 offers identical performance with enhanced environmental compliance labeling; versus TLV2374IDR, it provides 2.5× higher bandwidth and 2× faster slew rate at the cost of lacking shutdown functionality - making it optimal for always-on, high-fidelity analog signal chains.

FAQ
What is the maximum supply voltage for TLV274IPWRG4?
The absolute maximum supply voltage for TLV274IPWRG4 is 16.5 V, with recommended continuous operation up to 16 V. Exceeding this rating may cause permanent damage. The device operates across the full 2.7-V to 16-V range, supporting both single-supply (e.g., 3.3 V, 5 V, 12 V) and split-supply (±1.35 V to ±8 V) configurations. TLV274IPWRG4 maintains specified performance across this entire range.
Does TLV274IPWRG4 support rail-to-rail input?
No, TLV274IPWRG4 does not support rail-to-rail input - only rail-to-rail output. Its common-mode input voltage range is specified as 0 V to VDD − 1.35 V, meaning the inputs cannot operate within 1.35 V of the positive rail. However, the output swings within approximately 150 mV of both VDD and GND at 1-mA load, enabling full dynamic range utilization in low-voltage systems.
What is the input offset voltage specification for TLV274IPWRG4?
The input offset voltage for TLV274IPWRG4 is specified as a maximum of 5 mV at 25°C and 7 mV over the full industrial temperature range (–40°C to +125°C). This parameter is measured with VDD = 2.7 V, 5 V, or ±5 V, RL = 10 kΩ, VO = VDD/2, and RS = 50 Ω. Typical offset is 0.5 mV, making TLV274IPWRG4 suitable for precision DC-coupled applications where sub-millivolt errors are acceptable.
Can TLV274IPWRG4 drive capacitive loads directly?
TLV274IPWRG4 can drive capacitive loads ≤10 pF directly without external compensation. For loads >10 pF, Texas Instruments recommends adding a series resistor (RNULL ≥20 Ω) between the output and the capacitive load to maintain phase margin above 65° and prevent oscillation. This requirement is documented in the "Driving a Capacitive Load" section of the TLV274IPWRG4 datasheet and verified across temperature and supply voltage conditions.
Is TLV274IPWRG4 pin-compatible with other TLV27x variants?
Yes, TLV274IPWRG4 is pin-compatible with all TLV274 variants in the same TSSOP-14 package (e.g., TLV274IPW, TLV274CDR), sharing identical pinout, electrical specifications, and thermal characteristics. Differences are limited to packaging markings (G4 denotes green/RoHS-compliant tape-and-reel), temperature grade suffixes (I = industrial, C = commercial), and ordering options - not functional or mechanical compatibility.
