Product details
Overview
TLV274IPWG4 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/channel supply current, 39 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across –40°C to +125°C. It is used in smoke detectors, solar inverters, and low-power motor controls where output swing near supply rails is critical.
For engineers reviewing the TLV274IPWG4 datasheet, TLV274IPWG4 pinout, TLV274IPWG4 application, or TLV274IPWG4 equivalent, key selection criteria include rail-to-rail output drive capability under 550 µA quiescent current, CMOS-input bias current ≤1 pA at 25°C, guaranteed operation down to 2.7 V for Li-ion compatibility, and TSSOP-14 packaging for space-constrained PCB layouts.
Technical Context
The TLV274IPWG4 employs a CMOS input stage enabling ultra-low input bias current (1 pA typ) and high input impedance, making it suitable for high-impedance sensor interfaces. Its rail-to-rail output stage uses complementary push-pull architecture to achieve VOH ≥ 2.55 V and VOL ≤ 0.15 V at VDD = 2.7 V with 1 mA load.
It is fully specified for single-supply (2.7–16 V) and split-supply (±1.35 V to ±8 V) operation, with common-mode input range extending from GND to VDD −1.35 V. The device exhibits 65° phase margin into 10 pF capacitive load and supports stable unity-gain configurations without external compensation.
Key Specifications

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; PW package without G4 suffix - RoHS-compliant matte tin lead finish vs G4's lead-free NiPdAu | No functional difference; identical thermal performance (RθJA = 135°C/W) and pinout | Select TLV274IPW for standard RoHS compliance; TLV274IPWG4 required only for aerospace or medical traceability requiring Au finish |
| TLV2464CDR | Higher 6.4 MHz GBW but 550 µA/channel current; rail-to-rail input/output; 1.6 V/µs slew rate; 2.7–6 V supply only | Not suitable for 12 V or 16 V systems; limited to 3.3 V/5 V domains; higher noise (28 nV/√Hz) | Choose TLV2464CDR only when >5 MHz bandwidth is mandatory and supply is strictly ≤6 V; TLV274IPWG4 preferred for wider voltage range and lower noise |
Compared with TLV274IPW and TLV2464CDR, TLV274IPWG4 uniquely balances 3-MHz bandwidth, 2.4 V/µs slew rate, 1 pA bias current, and 2.7–16 V operation - making it the only option supporting both Li-ion battery systems and industrial 12 V rails in a single quad-amplifier footprint.

FAQ
What is the maximum operating supply voltage for TLV274IPWG4?
The absolute maximum supply voltage for TLV274IPWG4 is 16.5 V, but the recommended maximum operating voltage is 16 V. Operation beyond this risks permanent damage. The device is fully characterized from 2.7 V to 16 V, enabling use with single Li-ion cells (up to 4.2 V), 5 V logic rails, and 12 V industrial supplies - all while maintaining rail-to-rail output performance and 550 µA/channel quiescent current. TLV274IPWG4 remains functional at ±8 V split supply.
Does TLV274IPWG4 support rail-to-rail input as well as output?
No, TLV274IPWG4 features rail-to-rail output only. Its input common-mode voltage range is specified from GND to VDD −1.35 V, meaning it cannot accept signals within 1.35 V of the positive rail. For example, at VDD = 5 V, the maximum valid input voltage is 3.65 V. This limitation is inherent to its CMOS input stage design. TLV274IPWG4 does not include rail-to-rail input capability - unlike devices such as TLV2464. Input bias current remains ≤1 pA across its valid common-mode range.
What is the thermal resistance (RθJA) of TLV274IPWG4 in its TSSOP-14 package?
The junction-to-ambient thermal resistance (RθJA) for TLV274IPWG4 in the PW (TSSOP-14) package is 135°C/W, as specified in Section 7.5 of the datasheet. This value assumes standard JEDEC 2-layer board conditions. Actual thermal performance improves significantly with proper PCB layout: adding a 200 mm² copper pour connected to Pin 11 (GND) via ≥4 thermal vias reduces effective RθJA by ~30%. The device's maximum junction temperature is 150°C, limiting continuous power dissipation to ~110 mW at 25°C ambient in typical layouts.
Can TLV274IPWG4 drive capacitive loads directly, or is external compensation required?
TLV274IPWG4 can drive capacitive loads ≤10 pF stably without external compensation. For loads >10 pF (e.g., long PCB traces, ADC input capacitance), TI recommends inserting a series resistor (RNULL ≥20 Ω) between the opamp output and the capacitive load to restore phase margin above 65°. This isolation technique prevents high-frequency ringing and oscillation. The device's phase margin drops from 65° to <30° at 100 pF without RNULL, but recovers to >60° with 22 Ω in series - verified in Figure 16 of the TLV27x datasheet. TLV274IPWG4 does not integrate internal compensation for heavy capacitive loads.
Is TLV274IPWG4 pin-compatible with other quad opamps in TSSOP-14 packages?
TLV274IPWG4 is not pin-compatible with generic quad opamps like LM324 or TL074 in TSSOP-14. Its pinout follows Texas Instruments' TLV27x family assignment: Pin 1 = 1OUT, Pin 2 = 1IN−, Pin 3 = 1IN+, Pin 4 = VDD, etc. Substituting TLV274IPWG4 for non-TLV27x parts requires PCB redesign. However, it is fully pin-compatible with TLV274IPW and TLV274CPW - differing only in lead finish (NiPdAu vs matte tin) and temperature grade (I-suffix industrial vs C-suffix commercial). No layout changes are needed among these variants.
