Product details
Overview
TLC2274IPWR from Texas Instruments is a quad rail-to-rail output operational amplifier optimized for precision, low-noise signal conditioning in single- or split-supply systems. It delivers 2.2-MHz gain-bandwidth, 3.6-V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, 1-pA typical input bias current, and rail-to-rail output swing - enabling high-fidelity interfacing with ADCs in battery-powered sensor front-ends.
For engineers reviewing the TLC2274IPWR datasheet, TLC2274IPWR pinout, TLC2274IPWR application, or TLC2274IPWR equivalent, key selection criteria include its guaranteed 950-µV max input offset voltage (A-grade), ±5-V operation capability, 4.4–6-mA supply current across temperature, common-mode input range extending to VDD−, and TSSOP-14 package compatibility with space-constrained industrial monitoring designs.
Technical Context
The TLC2274IPWR uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise - distinguishing it from bipolar or standard CMOS op-amps. Its input stage supports common-mode voltages down to the negative rail, and its unity-gain-stable architecture enables direct use in unity-gain buffers without external compensation.
It operates over ±2.2 V to ±8 V supply ranges (or 4.4 V to 16 V single-supply), with full AC/DC specifications validated at both 5 V and ±5 V. The device exhibits 75–80 dB CMRR and 80–95 dB PSRR, supporting precision DC-coupled amplification in noisy industrial environments.
Key Specifications

Pinout & Package
TLC2274IPWR is housed in a 14-pin TSSOP package (4.40 mm × 5.00 mm body size) with exposed pad for thermal enhancement. Pin 1 is marked by a dot; pin numbering follows standard counter-clockwise convention from top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of Channel 1 - drives loads up to ±50 mA, rail-to-rail swing |
| 2 | IN1− | Inverting input of Channel 1 - high-impedance node (1012 Ω) for feedback network connection |
| 3 | IN1+ | Non-inverting input of Channel 1 - accepts common-mode signals down to VDD− |
| 4 | VDD+ | Positive supply rail - must be decoupled locally with 0.1-µF ceramic capacitor |
| 5 | IN2+ | Non-inverting input of Channel 2 - electrically isolated from other channels |
| 6 | IN2− | Inverting input of Channel 2 - matched to IN1− for dual-channel differential sensing |
| 7 | OUT2 | Amplified output of Channel 2 - independent output stage, no crosstalk below –80 dB |
| 8 | NC | No connection - internally unconnected; leave floating or tie to ground per layout best practice |
| 9 | IN3− | Inverting input of Channel 3 - supports third independent gain stage in compact layout |
| 10 | IN3+ | Non-inverting input of Channel 3 - identical electrical characteristics to IN1+ and IN2+ |
| 11 | VDD− | Negative supply rail - required for split-supply operation; ties to GND in single-supply mode |
| 12 | IN4+ | Non-inverting input of Channel 4 - enables simultaneous 4-channel signal conditioning on one IC |
| 13 | IN4− | Inverting input of Channel 4 - fully specified for matching and drift performance across all channels |
| 14 | OUT4 | Amplified output of Channel 4 - rail-to-rail swing, same drive strength as OUT1–OUT3 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2274CPW | Same silicon, commercial-grade (0°C to 70°C) with 2500-µV max VIO; otherwise identical pinout, specs, and package | Not qualified for extended temperature or industrial environments requiring >70°C operation | Select TLC2274IPWR for designs needing guaranteed 950-µV VIO and –40°C to 125°C operation. |
| TLV2434ID | Lower supply current (1.3 mA/ch), but reduced GBW (220 kHz), higher VIO (3000 µV), and no A-grade option | Better suited for micropower applications where bandwidth <250 kHz is acceptable | Choose TLV2434ID only if power budget is <6 mA total and precision <10-mV offset is sufficient. |
Compared with TLC2274CPW, the TLC2274IPWR provides tighter input offset voltage and extended temperature range at identical cost and footprint; versus TLV2434ID, it trades 3× higher supply current for 10× greater bandwidth and 3× lower offset voltage - making it optimal for precision, medium-speed industrial signal chains.

FAQ
What is the maximum operating supply voltage for the TLC2274IPWR?
The TLC2274IPWR supports a maximum supply voltage of ±8 V (or 16 V single-supply). Absolute maximum ratings specify VDD+ ≤ +8 V and VDD− ≥ –8 V. Operation beyond these limits risks permanent damage. Recommended operating range is ±2.2 V to ±8 V, with full specifications guaranteed at ±5 V and 5 V supplies.
Does the TLC2274IPWR support rail-to-rail input as well as rail-to-rail output?
The TLC2274IPWR features rail-to-rail *output* swing but only extends its common-mode input voltage range to the negative rail (VDD−); the positive end is limited to VDD+ −1.5 V. This allows true ground-referenced input in single-supply configurations but does not support full rail-to-rail input. For full rail-to-rail input/output, consider TI's TLV2464 or OPA4340 families.
What is the thermal resistance (θJA) of the TLC2274IPWR in its TSSOP-14 package?
The TLC2274IPWR in the PW (TSSOP-14) package has a junction-to-ambient thermal resistance (θJA) of 111.6°C/W, as specified in the datasheet's Thermal Information table. This value assumes standard JEDEC 2-layer board conditions. Layout with adequate copper pour under the exposed pad can reduce effective θJA by up to 25°C/W.
Can the TLC2274IPWR drive capacitive loads directly, and what is its stability limit?
The TLC2274IPWR is unity-gain stable and characterized with 100-pF capacitive load in all AC specifications. Phase margin remains ≥50° under these conditions. For loads >200 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to maintain stability. The device is not optimized for direct 1-nF+ load driving without compensation.
How does the TLC2274IPWR differ from the standard TLC2274 (non-A, non-I) version?
The TLC2274IPWR is the "I" (industrial) grade and "A" (precision) variant: it guarantees ≤950 µV input offset voltage (vs. ≤2500 µV for standard TLC2274) and operates across –40°C to +125°C (vs. 0°C to +70°C for commercial "C" grade). All other electrical parameters, pinout, and package are identical - making it a drop-in upgrade for higher-accuracy, wider-temperature applications.
