Product details
Overview
TLV274CPW 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 E-bikes, smoke detectors, and solar inverters.
For engineers reviewing the TLV274CPW datasheet, TLV274CPW pinout, TLV274CPW application, or TLV274CPW equivalent, key selection criteria include guaranteed rail-to-rail output swing at 2.7 V, picoampere-level input bias current (1 pA typ), −40°C to +125°C industrial temperature operation, and compatibility with Li-ion and MSP430-based platforms requiring micropower analog performance.
Technical Context
The TLV274CPW employs CMOS input stage architecture enabling ultra-low input bias current (1 pA typ) and high input impedance (>1 TΩ), making it suitable for high-impedance sensor interfaces such as photodiode amplifiers and thermistor networks. Its rail-to-rail output stage uses complementary push-pull circuitry to achieve <150 mV saturation headroom at ±1 mA load over full temperature range.
It operates stably under capacitive loads up to 10 pF without external compensation; for >10 pF, TI recommends series output resistance (≥20 Ω) to maintain ≥65° phase margin. The device is fully specified for single-supply (2.7–16 V) and split-supply (±1.35–±8 V) configurations, with common-mode input range extending from GND to VDD −1.35 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports direct interface with Li-ion cells (3.0–4.2 V), 5 V logic rails, and ±5 V industrial supplies. |
| Bandwidth (UGBW) | 3 MHz - enables stable closed-loop gain ≥10 at 300 kHz, suitable for anti-aliasing and active filter stages. |
| Slew Rate | 2.4 V/µs - ensures ≤2 µs settling to 0.1% for 1 V step, critical for fast pulse conditioning in smoke detector analog front-ends. |
| Input Bias Current | 1 pA typical - minimizes voltage error in high-Z sensor circuits (e.g., pH electrodes, piezoelectric transducers). |
| Input Noise Voltage | 39 nV/√Hz at 1 kHz - provides <1.5 µV RMS integrated noise in 10 kHz bandwidth, supporting 12-bit+ resolution in battery-powered instruments. |
| Rail-to-Rail Output | Swings within 150 mV of rails at ±1 mA - maximizes dynamic range in 3.3 V microcontroller ADC interfaces without level-shifting. |
| Quiescent Current | 550 µA per channel - allows four-channel operation at <2.2 mA total, extending runtime in power banks and building automation nodes. |
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 | Amplified output of Channel 1 - drives feedback network or next-stage input; capable of sourcing/sinking ±10 mA. |
| 2 | 1IN− | Inverting input of Channel 1 - connects to feedback resistor or summing junction; high-impedance CMOS node. |
| 3 | 1IN+ | Noninverting input of Channel 1 - interfaces directly with sensors or reference voltages; immune to leakage-induced offset. |
| 4 | VDD | Positive supply rail - must be decoupled with ≥0.1 µF ceramic capacitor placed ≤5 mm from pin. |
| 5 | 2IN+ | Noninverting input of Channel 2 - electrically isolated from other inputs; supports independent dual-sensor monitoring. |
| 6 | 2IN− | Inverting input of Channel 2 - used for differential measurement or inverting gain configuration. |
| 7 | 2OUT | Amplified output of Channel 2 - shares no internal coupling with Channel 1; crosstalk <−80 dB at 10 kHz. |
| 8 | 3OUT | Amplified output of Channel 3 - enables three-channel signal path (e.g., RGB sensor conditioning) without external opamps. |
| 9 | 3IN− | Inverting input of Channel 3 - referenced to same VDD/GND as all channels; no separate supply pins required. |
| 10 | 3IN+ | Noninverting input of Channel 3 - supports high-side current sensing when paired with precision shunt resistor. |
| 11 | GND | Ground reference - return path for all four channels; requires low-inductance connection to system ground plane. |
| 12 | 4IN+ | Noninverting input of Channel 4 - enables fourth independent analog channel (e.g., temperature + voltage + current + fault detection). |
| 13 | 4IN− | Inverting input of Channel 4 - configurable as comparator input with hysteresis via external resistors. |
| 14 | 4OUT | Amplified output of Channel 4 - full rail-to-rail swing available; compatible with 3.3 V ADC reference inputs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV274CDR | SOIC-14 package (8.65 mm × 3.91 mm); higher RθJA (97°C/W vs 135°C/W); identical electrical specs. | Preferred for through-hole prototyping or legacy PCBs with SOIC footprints; less suitable for space-constrained power bank designs. | Select TLV274CDR when board layout accommodates larger SOIC footprint and thermal management uses copper pour rather than forced air. |
| TLV2464CDR | Lower bandwidth (6.4 MHz), higher supply current (550 µA vs 725 µA), rail-to-rail input/output, but only specified to 6 V max supply. | Better for 3.3 V-only systems needing higher speed; unsuitable for 12 V solar inverter auxiliary rails or 16 V industrial supplies. | Choose TLV2464CDR only if design operates strictly ≤6 V and requires >3 MHz bandwidth - not a drop-in replacement for TLV274CPW's 2.7–16 V range. |
Compared with TLV274CDR and TLV2464CDR, the TLV274CPW uniquely balances ultra-low input bias current, wide supply range, and rail-to-rail output in a space-efficient TSSOP package - making it optimal for compact, multi-voltage industrial and portable systems where leakage-sensitive sensing and thermal density are co-constraints.

FAQ
What is the maximum supply voltage rating for TLV274CPW?
The absolute maximum supply voltage for TLV274CPW is 16.5 V, with recommended operation up to 16 V. Exceeding this risks permanent damage. The device supports both single-supply (2.7–16 V) and split-supply (±1.35–±8 V) configurations, making TLV274CPW suitable for 12 V industrial rails and dual ±5 V test equipment without external regulators.
Does TLV274CPW support rail-to-rail input operation?
No, TLV274CPW features rail-to-rail *output* only. Its common-mode input voltage range is 0 V to VDD −1.35 V, meaning the inputs cannot swing to the positive rail. For true rail-to-rail input/output, consider TI's TLV2374 or OPA333 families - TLV274CPW prioritizes ultra-low input bias current and wide supply range over full input range.
What is the thermal resistance (RθJA) of TLV274CPW in the PW (TSSOP-14) package?
The junction-to-ambient thermal resistance (RθJA) for TLV274CPW in the PW package is 135°C/W, per TI's SLOS351E datasheet Section 7.5. This value assumes standard JEDEC 2-layer board conditions; actual thermal performance improves significantly with PCB copper pour under the exposed pad area, though the PW package lacks an exposed thermal pad.
Can TLV274CPW drive capacitive loads directly?
TLV274CPW is stable driving ≤10 pF capacitive loads without external compensation. For loads >10 pF (e.g., long PCB traces or ADC input capacitance), TI recommends adding a 20–100 Ω series resistor between TLV274CPW output and the load to preserve phase margin ≥65° and prevent oscillation - confirmed in Section 8.3.3 of the TLV274CPW datasheet.
Is TLV274CPW qualified for automotive applications?
TLV274CPW is not AEC-Q200 qualified. It is rated for industrial temperature range (−40°C to +125°C) and carries the 'I' suffix in part numbering (e.g., TLV274IPW), but the 'C' suffix in TLV274CPW indicates commercial grade (0°C to +70°C). For automotive use, specify TLV274IPW or consult TI's automotive-grade alternatives like LMV324Q.
