Product details
Overview
TLV2774AIN from Texas Instruments is a quad rail-to-rail output CMOS operational amplifier optimized for single-supply operation (2.5 V to 5.5 V), delivering 5.1 MHz gain-bandwidth, 10.5 V/µs slew rate, 360 µV input offset voltage, and 1 mA per-channel supply current - enabling high-fidelity signal conditioning in automotive sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2774AIN datasheet, TLV2774AIN pinout, TLV2774AIN application, or TLV2774AIN equivalent, this page provides verified package mapping (14-pin PDIP), confirmed shutdown functionality (1.3 µA max shutdown current), temperature-rated performance (−40°C to 125°C), and real-world design implications for ADC driver, battery-powered instrumentation, and low-voltage analog front-ends.
Technical Context
The TLV2774AIN uses a CMOS input stage with 2 pA typical input bias current and 17 nV/√Hz input noise voltage, supporting precision DC-coupled measurements. Its rail-to-rail output swing enables full dynamic range utilization when driving SAR or sigma-delta ADC reference inputs at 2.7 V or 5 V supplies.
It features micropower shutdown mode (IDD < 1.5 µA per channel) and is characterized across −40°C to 125°C, meeting automotive-grade reliability requirements without external thermal compensation. The device exhibits 0.005% THD+N into 600 Ω, confirming suitability for telecom line-driver and audio preamp roles where distortion matters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion battery rails or 3.3 V/5 V system supplies without regulation. |
| Gain-Bandwidth Product | 5.1 MHz - enables stable unity-gain buffer or closed-loop gain ≥2 up to ~2.5 MHz for anti-aliasing filter stages. |
| Slew Rate | 10.5 V/µs - ensures ≤0.6 µs 0.01% settling for 2 V step, critical for fast-settling ADC drivers. |
| Input Offset Voltage | 360 µV max - reduces DC error in 12-bit systems with 1.22 mV LSB at 5 V full-scale. |
| Supply Current per Channel | 1 mA - allows four-channel operation at <4 mA total, ideal for always-on sensor signal chains. |
| Shutdown Current | 1.3 µA max - enables power gating between measurement cycles to extend battery life in portable devices. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive applications and industrial control environments. |
Pinout & Package
TLV2774AIN is supplied in a 14-pin plastic DIP (PDIP) package with 0.300-inch body width and through-hole mounting. Pin 1 is identified by a beveled edge or molded dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives 600 Ω load with <0.005% THD+N. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (10¹² Ω), sensitive to PCB leakage. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - matched to Pin 2 for optimal common-mode rejection. |
| 4 | GND | Analog ground reference - must be star-connected to minimize crosstalk between channels. |
| 5 | VDD | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 inputs per layout guidelines. |
| 7 | 2IN− | Inverting input of Channel 2 - symmetrical layout recommended to match Pin 2 parasitics. |
| 8 | 2OUT | Output of Channel 2 - independent output stage; no internal cross-coupling with Channel 1. |
| 9 | 3OUT | Output of Channel 3 - shares same die substrate as other channels; thermal coupling affects offset drift. |
| 10 | 3IN− | Inverting input of Channel 3 - routed away from digital traces to avoid EMI-induced offset shifts. |
| 11 | 3IN+ | Non-inverting input of Channel 3 - matched pair with Pin 10 for differential input configurations. |
| 12 | GND | Second ground pin - connects to same ground plane as Pin 4; improves PSRR at high frequencies. |
| 13 | 4IN− | Inverting input of Channel 4 - referenced to Pin 12 ground for lowest noise floor in multi-channel sensing. |
| 14 | 4OUT | Output of Channel 4 - fully specified for rail-to-rail swing and 2.2 mA drive capability. |
Key Features
| Feature | Design Value |
|---|---|

| 17 nV/√Hz input noise | Supports sub-16-bit resolution in precision weigh-scale and medical ECG front-ends. |
| Micropower shutdown mode | Reduces quiescent current to <1.5 µA per channel - extends shelf life in battery-backed data loggers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2774IDR | Same electrical specs, but in SOIC-14 package (surface-mount); no through-hole option. | Preferred for automated PCB assembly; not suitable for prototyping or legacy through-hole designs. | Select TLV2774IDR only if board layout supports SOIC footprint and reflow soldering is available. |
| OPA2377AIDR | Lower input offset (25 µV typ), higher GBW (5.5 MHz), but higher supply current (1.6 mA/ch) and no shutdown mode. | Better for ultra-precision DC applications; unsuitable where micropower shutdown is required. | Choose OPA2377AIDR when offset drift dominates system error budget and continuous operation is acceptable. |
Compared with TLV2774AIN, TLV2774IDR offers identical performance in a surface-mount package for volume production, while OPA2377AIDR trades shutdown capability and lower power for improved DC precision - making TLV2774AIN the sole choice for battery-gated, automotive-qualified, through-hole quad op-amp needs.

FAQ
What is the maximum operating temperature range for TLV2774AIN?
The TLV2774AIN is rated for operation from −40°C to 125°C, meeting AEC-Q100 Grade 2 automotive qualification requirements. This range is validated across all key parameters including input offset voltage, CMRR, and supply current - ensuring reliable performance in under-hood and industrial control environments without derating.
Does TLV2774AIN support rail-to-rail input as well as output?
No, TLV2774AIN features rail-to-rail output only. Its input common-mode voltage range extends from GND to VDD − 1.3 V at 2.7 V supply, meaning it cannot accept signals within 1.3 V of VDD. For true rail-to-rail input capability, consider TI's TLV2464 or OPA4376 families instead.
Can TLV2774AIN drive a 600-Ω load with low distortion?
Yes, TLV2774AIN delivers 0.005% THD+N into a 600-Ω load at 1 kHz with AV = 1, as confirmed in the datasheet's operating characteristics table. This performance is enabled by its high slew rate (10.5 V/µs) and robust output stage, making it suitable for telecom line drivers and audio preamplifiers.
Is the shutdown function of TLV2774AIN controlled per channel or globally?
TLV2774AIN does not include individual channel shutdown. It has no dedicated shutdown pin - the "shutdown" capability referenced in the datasheet applies only to the TLV2773 and TLV2775 variants (which feature SHDN pins). TLV2774AIN operates continuously; power must be removed externally to achieve low-quiescent states.
What is the input bias current specification for TLV2774AIN at 125°C?
At 125°C, the input bias current for TLV2774AIN is guaranteed ≤350 pA (max), as specified in the TLV277xAI electrical characteristics tables. This value reflects worst-case drift over temperature and remains sufficiently low for high-impedance sensor interfaces such as pH electrodes or photodiode transimpedance stages.
