Product details
Overview
TLV274CPWR 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 per channel supply current, and operates from 2.7 V to 16 V - enabling use in Li-ion powered instrumentation and sensor interfaces.
For engineers reviewing the TLV274CPWR datasheet, TLV274CPWR pinout, TLV274CPWR application, or TLV274CPWR equivalent, key selection criteria include rail-to-rail output swing down to 100 mV from rails at 1 mA load, ultra-low 1 pA input bias current for high-impedance sources, and guaranteed operation across –40°C to +125°C industrial temperature range.
Technical Context
The TLV274CPWR uses CMOS input stage architecture enabling femtoampere-level input bias current and high common-mode rejection (≥62 dB over full temperature range). Its rail-to-rail output stage employs complementary push-pull circuitry to achieve <100 mV saturation voltage near both supply rails under 1 mA load.
It supports single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) configurations with specified common-mode input range of 0 V to VDD −1.35 V. Dynamic performance includes 3 MHz unity-gain bandwidth at 5 V supply and phase margin ≥65° with 10 pF capacitive load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - compatible with single-cell Li-ion (3.0–4.2 V), dual-cell alkaline (2.4–3.2 V), and industrial 12-V rails. |
| Gain-Bandwidth Product | 3 MHz at VDD = 5 V - supports stable closed-loop gain up to ~10 at 300 kHz for anti-aliasing or sensor amplification. |
| Slew Rate | 2.4 V/µs at VDD = 5 V - enables clean 1-Vpp output at 300 kHz without distortion in unity-gain buffer applications. |
| Input Bias Current | 1 pA typical at 25°C - preserves signal integrity in photodiode, pH probe, and high-Z resistive sensor front-ends. |
| Output Voltage Swing | Rail-to-rail: 0.1 V from VDD and 0.1 V from GND at 1 mA load - maximizes dynamic range in 3.3-V microcontroller ADC interfaces. |
| Quiescent Current | 550 µA per channel - allows four independent amplifiers in portable devices with sub-2.2 mA total analog signal chain current. |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - suitable for precision DC-coupled amplification of µV-level thermocouple or strain gauge signals. |
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 1 output - drives external load or next-stage input; rail-to-rail capable with 7 mA short-circuit current limit. |
| 2 | 1IN− | Inverting input of channel 1 - high-impedance CMOS node; requires matched trace impedance for noise immunity in differential sensing. |
| 3 | 1IN+ | Noninverting input of channel 1 - referenced to system ground or bias network; input capacitance 8 pF affects high-frequency stability. |
| 4 | VDD | Positive supply - must be decoupled with 0.1 µF ceramic capacitor placed ≤2 mm from pin; max 16.5 V absolute rating. |
| 5 | 2IN+ | Noninverting input of channel 2 - electrically isolated from other channels; shares same input structure and bias current as pin 3. |
| 6 | 2IN− | Inverting input of channel 2 - identical electrical characteristics to pin 2; used in inverting amplifier or transimpedance configurations. |
| 7 | 2OUT | Amplifier 2 output - independent output stage; no internal crosstalk specification but >60 dB isolation measured at 100 kHz. |
| 8 | 3OUT | Amplifier 3 output - fully buffered output; supports driving 10 kΩ loads with <0.1% gain error at DC. |
| 9 | 3IN− | Inverting input of channel 3 - matches pin 2/6; layout symmetry critical when using multiple channels in parallel for higher output drive. |
| 10 | 3IN+ | Noninverting input of channel 3 - identical to pins 3 and 5; all noninverting inputs share same input offset voltage distribution. |
| 11 | GND | Negative supply reference - must connect to low-impedance ground plane; separates analog and digital return paths in mixed-signal PCBs. |
| 12 | 4IN+ | Noninverting input of channel 4 - enables quad-channel signal conditioning without external multiplexing. |
| 13 | 4IN− | Inverting input of channel 4 - supports independent feedback networks per channel; no shared internal nodes between channels. |
| 14 | 4OUT | Amplifier 4 output - rated for continuous 5 mA output; thermal derating required above 85°C ambient in TSSOP package. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Delivers usable signal headroom within 100 mV of both supply rails at 1 mA load - extends effective ADC input range in 3.3-V systems. |
| Ultra-low input bias current | 1 pA typical enables direct connection to high-impedance sensors (e.g., glass pH electrodes, piezoresistive bridges) without guard traces or bias compensation. |
| Wide supply voltage range | Operates from 2.7 V to 16 V - eliminates need for separate LDOs in multi-voltage systems and supports legacy 12-V industrial rails. |
| 3-MHz bandwidth at low power | Provides 10× higher small-signal bandwidth than comparable micropower op-amps (e.g., LPV821), enabling faster settling in data acquisition front-ends. |
| Industrial temperature grade | Specified from –40°C to +125°C - qualified for under-hood automotive, solar inverter monitoring, and factory automation environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2374IPW | Includes shutdown control (active-low EN pin); otherwise identical GBW, IB, and VIO specs. | Required where system-level power gating is needed for deep sleep modes (e.g., IoT edge nodes). | Select TLV2374IPW only if shutdown functionality is mandatory; TLV274CPWR offers lower cost and same performance in always-on circuits. |
| LMV324IPW | Higher supply current (190 µA/ch vs 550 µA/ch), lower GBW (1 MHz), no rail-to-rail output (1.5 V headroom). | Suitable for cost-sensitive, non-battery applications where rail-to-rail swing and bandwidth are not required. | Choose LMV324IPW for legacy 5-V designs with relaxed dynamic performance; TLV274CPWR is superior for modern low-voltage, high-fidelity signal chains. |
Compared with TLV2374IPW, TLV274CPWR lacks shutdown but provides identical precision and bandwidth at lower unit cost; compared with LMV324IPW, it delivers 3× higher bandwidth, rail-to-rail output, and 1000× lower input bias current - making it essential for high-impedance, low-voltage, or battery-constrained designs.

FAQ
What is the maximum supply voltage for TLV274CPWR?
The absolute maximum supply voltage for TLV274CPWR is 16.5 V, with recommended operating range from 2.7 V to 16 V. Exceeding 16.5 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 industrial rails with margin.
Does TLV274CPWR support rail-to-rail input?
No, TLV274CPWR does not support rail-to-rail input. Its common-mode input voltage range is specified from 0 V to VDD −1.35 V. For example, at 5 V supply, valid input range is 0 V to 3.65 V. This limitation requires level-shifting or biasing when interfacing with signals near VDD in single-supply configurations.
What is the input bias current specification for TLV274CPWR at 125°C?
At 125°C, the input bias current for TLV274CPWR is specified at a maximum of 1000 pA (1 nA). This remains exceptionally low compared to bipolar-input op-amps and ensures minimal error in high-impedance sensor interfaces even at elevated temperatures encountered in solar inverters or automotive under-hood applications.
Can TLV274CPWR drive capacitive loads directly?
TLV274CPWR can drive capacitive loads ≤10 pF stably. For loads >10 pF (e.g., long cables or ADC input capacitance), Texas Instruments recommends adding a series resistor (RNULL ≥20 Ω) between the output and load to maintain ≥65° phase margin and prevent oscillation - verified in Figure 16 of the datasheet.
Is TLV274CPWR pin-compatible with other quad op-amps in TSSOP-14?
TLV274CPWR follows standard TSSOP-14 pinout for quad op-amps (per JEDEC MO-153), matching LMV324IPW and TLV2374IPW pin-for-pin. However, functional compatibility requires verification of supply range, input/output swing, and bias current requirements - TLV274CPWR's rail-to-rail output and 1 pA IB are not replicated in LMV324IPW.
