Product details
Overview
TLV274CD 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 39 nV/√Hz input voltage noise across a 2.7 V to 16 V supply range - enabling precision sensing and analog front-end design in smoke detectors and solar inverters.
For engineers reviewing the TLV274CD datasheet, TLV274CD pinout, TLV274CD application, or TLV274CD equivalent, this page provides verified package mapping (SOIC-14), confirmed quad-channel rail-to-rail output behavior, validated thermal metrics (RθJA = 97°C/W), real-world noise performance (39 nV/√Hz at 1 kHz), and direct alternative part comparisons with functional trade-offs.
Technical Context
The TLV274CD uses CMOS input stage architecture delivering 1 pA typical input bias current and rail-to-rail output swing down to within 135 mV of each rail under 1 mA load. Its 3-MHz gain-bandwidth product remains stable across 2.7–16 V supply operation, supporting both single-supply (e.g., 3.3 V Li-ion) and split-supply (±5 V) configurations without performance degradation.
It features 58–85 dB common-mode rejection ratio (CMRR) depending on supply voltage and temperature, 70–80 dB power-supply rejection ratio (PSRR), and 0.5–7 mV input offset voltage over temperature - making it suitable for high-impedance sensor interfaces where DC accuracy and low-noise AC response are jointly required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 3 MHz unity-gain bandwidth enables stable closed-loop operation up to ~50 kHz in second-order filter designs. |
| Slew Rate | 2.4 V/µs supports clean 100-kHz sine-wave output at ±2 V amplitude without distortion. |
| Supply Current | 550 µA per channel allows four op-amps to operate within 2.2 mA total - critical for ultra-low-power system budgeting. |
| Input Noise | 39 nV/√Hz at 1 kHz sets floor for sub-10 µV RMS noise in 100-Hz–10-kHz sensor signal chains. |
| Rail-to-Rail Output | Swings to within 135 mV of VDD and GND at 1 mA load - maximizes dynamic range in 3.3 V or 5 V systems. |
| Input Bias Current | 1 pA typical enables use with >100 MΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without significant error. |
| Offset Voltage | 5 mV typical (7 mV max over full temp range) ensures <0.1% gain error in unity-gain buffer applications. |
Pinout & Package
TLV274CD is packaged in 14-pin SOIC (D package), body size 8.65 mm × 3.91 mm, with standard JEDEC MS-012AC footprint and 1.27 mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives external load or feedback network; rail-to-rail capable. |
| 2 | 1IN− | Inverting input of Channel 1 - connects to feedback resistor or signal inversion node. |
| 3 | 1IN+ | Noninverting input of Channel 1 - accepts high-impedance sensor or reference signals. |
| 4 | VDD | Positive supply terminal - accepts 2.7 V to 16 V; decoupling capacitor required at pin. |
| 5 | 2IN− | Inverting input of Channel 2 - electrically isolated from other channels; no internal connection to pin 13. |
| 6 | 2IN+ | Noninverting input of Channel 2 - independent bias path; supports dual-sensor monitoring. |
| 7 | 2OUT | Output of Channel 2 - fully buffered; shares no internal nodes with Channel 1 output. |
| 8 | 3OUT | Output of Channel 3 - identical electrical specs to pins 1 and 7; usable as third independent amplifier. |
| 9 | 3IN− | Inverting input of Channel 3 - matches pin 2 function; no crosstalk with pins 5 or 13. |
| 10 | 3IN+ | Noninverting input of Channel 3 - supports three simultaneous analog signal paths. |
| 11 | GND | Ground reference for all four amplifiers - must be low-impedance return path for all channels. |
| 12 | 4IN+ | Noninverting input of Channel 4 - completes quad configuration; pin 12 and 14 are active inputs. |
| 13 | 4IN− | Inverting input of Channel 4 - independent of all other inverting inputs; no shared substrate coupling. |
| 14 | 4OUT | Output of Channel 4 - delivers fourth independent rail-to-rail output; full 3-MHz bandwidth preserved. |
Key Features

Applications
| Smoke Detector Signal Conditioning | Solar Inverter MPPT Reference Buffer |
|---|---|
Use Scenario: Amplifying weak ionization chamber current (pA–nA range) into measurable voltage for microcontroller ADC sampling. IC Role / Device Role / Timing Role: Quad TLV274CD configures one channel as transimpedance amplifier, two as active filters, and one as comparator reference buffer. Use Value: 1 pA input bias prevents signal loss; rail-to-rail output ensures full-scale ADC utilization; 39 nV/√Hz noise preserves detection SNR. | Use Scenario: Buffering precision voltage reference (e.g., REF5025) to multiple MPPT controller channels while rejecting switching noise. IC Role / Device Role / Timing Role: Single TLV274CD channel used as unity-gain buffer; remaining channels condition PV string current/voltage feedback. Use Value: 85 dB PSRR at 100 kHz suppresses inverter gate-drive coupling; 550 µA/channel minimizes thermal drift in sealed enclosures. |
| Low-Power Motor Control Feedback | Building Automation Sensor Hub |
Use Scenario: Closed-loop current sensing in BLDC motor drivers using shunt resistors, with analog filtering before MCU ADC. IC Role / Device Role / Timing Role: Two TLV274CD channels implement 2nd-order anti-aliasing filters; third buffers hall-effect position signal.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274IDR | Same electrical specs; rated for –40°C to +125°C industrial grade (I-suffix) vs C-suffix commercial grade (0°C to 70°C). | Required for automotive or outdoor industrial deployments; not needed for indoor consumer-grade devices. | Select TLV274IDR when operating ambient exceeds 70°C or requires extended temperature qualification. |
| TLV2464CDR | Lower 6.4 MHz GBW but adds shutdown mode; higher 550 µA/channel supply current; rail-to-rail input/output. | Better for battery systems needing power gating; unsuitable where 3-MHz bandwidth is mandatory (e.g., fast filter settling). | Choose TLV2464CDR only if shutdown functionality is essential and bandwidth margin >2× design requirement exists. |
Compared with TLV274IDR, TLV274CD offers lower cost and sufficient temperature range for commercial HVAC controls; versus TLV2464CDR, it provides higher bandwidth and simpler enable logic but lacks power-down capability - making TLV274CD optimal for always-on, speed-critical analog signal chains.

FAQ
What is the maximum supply voltage for TLV274CD?
The absolute maximum supply voltage for TLV274CD is 16.5 V, but the recommended operating maximum is 16 V. Operation above 16 V risks permanent damage. The device functions correctly across 2.7 V to 16 V, supporting single-supply (e.g., 3.3 V, 5 V, 12 V) and split-supply (±1.35 V to ±8 V) configurations. Always observe derating guidelines in TI's SLOS351E datasheet Section 7.1.
Does TLV274CD support rail-to-rail input?
No, TLV274CD does not support rail-to-rail input. It features rail-to-rail *output* only. The input common-mode voltage range is specified as 0 V to VDD − 1.35 V, meaning the inputs cannot swing within 1.35 V of the positive rail. This limitation must be considered when designing sensor interfaces near VDD - for true rail-to-rail input/output, consider TLV2374 or TLV2464 families instead.
What is the thermal resistance (RθJA) of TLV274CD in SOIC-14 package?
The junction-to-ambient thermal resistance (RθJA) for TLV274CD in the SOIC-14 (D) package is 97°C/W, as measured per JEDEC JESD51-2 standards on a 2S2P test board. This value assumes standard copper pour and no additional heatsinking. For continuous 4-channel operation at full 16 V supply, junction temperature rise remains within safe limits below 125°C ambient when PCB layout follows TI's layout guidelines in Section 11 of SLOS351E.
Can TLV274CD drive capacitive loads directly?
TLV274CD can drive ≤10 pF capacitive loads stably without external compensation. For loads >10 pF (e.g., long traces, ADC input capacitance), TI recommends adding a series resistor (RNULL ≥20 Ω) between the output pin and the load to maintain phase margin >65° and prevent oscillation. This is documented in Section 8.3.3 and Figure 26 of the TLV274CD datasheet SLOS351E.
Is TLV274CD pin-compatible with other quad op-amps like LM324?
No, TLV274CD is not pin-compatible with LM324. While both are quad op-amps in 14-pin packages, TLV274CD uses standard SOIC-14 pinout (GND on pin 11, VDD on pin 4), whereas LM324 places VDD on pin 4 and GND on pin 11 - same physical location but reversed function. Additionally, TLV274CD has no internal ESD diodes to rails, unlike LM324, so input voltage limits differ. Direct replacement requires PCB redesign.
