Product details
Overview
TLC2274AIPWR 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, 950-µV max input offset voltage (TA = 25°C), 9 nV/√Hz input voltage noise at 1 kHz, and ±500-µA output drive capability - enabling high-fidelity analog front-ends in battery-powered transducer interfaces.
For engineers reviewing the TLC2274AIPWR datasheet, TLC2274AIPWR pinout, TLC2274AIPWR application, or TLC2274AIPWR equivalent, key selection criteria include rail-to-rail output swing (±4.6 V at ±5 V supply), ultra-low input bias current (1 pA typical), common-mode input range extending to negative rail, and guaranteed performance across –40°C to 125°C for industrial sensing and ADC driver use cases.
Technical Context
The TLC2274AIPWR uses advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its input stage supports common-mode voltages down to VDD−, making it suitable for ground-referenced sensor signals without level-shifting circuitry.
It operates over ±2.2 V to ±8 V dual-supply or 4.4 V to 16 V single-supply ranges, with full AC/DC specifications validated at both 5 V and ±5 V conditions. The device features internal compensation for unity-gain stability with 100-pF capacitive load and exhibits 50° phase margin under standard test conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 2.25 MHz - enables stable closed-loop operation up to ~200 kHz at AV = 10 for anti-aliasing filter design |
| Slew rate | 3.6 V/µs - supports 1-Vpp signals up to ~570 kHz without distortion in unity-gain buffer configurations |
| Input offset voltage | ≤950 µV at TA = 25°C - ensures ≤0.02% error in 5-V full-scale instrumentation amplifier stages |
| Input voltage noise | 9 nV/√Hz at 1 kHz - critical for preserving SNR in high-impedance piezoelectric or pH sensor amplification |
| Input bias current | 1 pA typical - prevents significant DC error when driving >100-MΩ source impedances |
| Common-mode input range | Extends to VDD− - allows direct interfacing with 0-V referenced thermistors or bridge sensors |
| Supply voltage range | ±2.2 V to ±8 V (dual) or 4.4 V to 16 V (single) - compatible with Li-ion, 5-V, and ±5-V legacy systems |
Pinout & Package
TLC2274AIPWR is packaged in a 14-pin TSSOP (PW package) with nominal body size 4.40 mm × 5.00 mm, optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Output of Channel 1 - rail-to-rail swing supports direct connection to SAR ADC inputs |
| 2 | IN1− | Inverting input of Channel 1 - matched with IN1+ for differential gain configuration |
| 3 | IN1+ | Non-inverting input of Channel 1 - accepts signals down to VDD−, enabling single-supply sensor biasing |
| 4 | VDD+ | Positive supply terminal - must be decoupled locally with ≥0.1 µF ceramic capacitor |
| 5 | IN2+ | Non-inverting input of Channel 2 - electrically isolated from Channel 1 for multi-sensor conditioning |
| 6 | IN2− | Inverting input of Channel 2 - supports precision current-to-voltage conversion with feedback resistor |
| 7 | OUT2 | Output of Channel 2 - independent output stage avoids crosstalk in multi-channel monitoring |
| 8 | NC | No connection - not bonded; must remain unconnected per TI specification |
| 9 | IN3− | Inverting input of Channel 3 - shares same process characteristics as Channels 1–2 for matched performance |
| 10 | IN3+ | Non-inverting input of Channel 3 - usable for third sensor channel or reference buffer |
| 11 | VDD− | Negative supply terminal - required for dual-supply operation; tied to GND in single-supply mode |
| 12 | IN4+ | Non-inverting input of Channel 4 - supports simultaneous 4-channel signal acquisition |
| 13 | IN4− | Inverting input of Channel 4 - enables fourth independent op-amp function without external components |
| 14 | OUT4 | Output of Channel 4 - fully specified for load currents up to ±5 mA at room temperature |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2434IDR | Lower supply current (1.2 mA/ch vs. 1.2 mA total for TLC2274A), but reduced GBW (1.8 MHz) and higher VIO (1.5 mV max) | Better suited for ultra-low-power, lower-precision battery monitoring where bandwidth <1 MHz suffices | Select TLV2434IDR only if supply current reduction outweighs need for 2.25-MHz bandwidth and sub-mV offset |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift), lower VIO (10 µV max), but higher cost and 360-µA/ch supply current | Ideal for precision weigh scales or medical diagnostics requiring long-term DC stability, not general-purpose signal conditioning | Choose OPA2333AIDR when µV-level offset stability over temperature is mandatory; avoid for cost-sensitive industrial controls |
Compared with TLV2434IDR and OPA2333AIDR, the TLC2274AIPWR offers balanced performance: superior bandwidth and rail-to-rail output versus TLV2434IDR, and significantly lower cost and higher output drive versus OPA2333AIDR - making it optimal for mid-tier industrial and consumer sensing.

FAQ
What is the maximum operating temperature range for the TLC2274AIPWR?
The TLC2274AIPWR is rated for operation from –40°C to +125°C across all grade levels (I and Q), with full electrical specifications guaranteed over this range. This makes the TLC2274AIPWR suitable for under-hood automotive modules and industrial control cabinets where ambient temperatures exceed 85°C. The device's thermal design supports continuous operation at maximum junction temperature without derating.
Does the TLC2274AIPWR support single-supply operation?
Yes, the TLC2274AIPWR is fully specified for single-supply operation from 4.4 V to 16 V. In this configuration, VDD− is connected to ground, and the common-mode input range extends to VDD− (0 V), allowing direct interfacing with ground-referenced sensors. Output swing reaches within 15 mV of ground and within 10 mV of VDD+, ensuring compatibility with 3.3-V or 5-V ADC references.
What is the input offset voltage specification for the TLC2274AIPWR?
The TLC2274AIPWR has a maximum input offset voltage of 950 µV at TA = 25°C and 1500 µV over the full temperature range (–40°C to +125°C). This tighter VIO spec differentiates the "A" variant from the base TLC2274, which is rated at 2500 µV max at 25°C. The specification applies to all four channels independently and is verified per TI's production test flow.
Can the TLC2274AIPWR drive a 10-kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC2274AIPWR maintains rail-to-rail output swing into 10-kΩ loads. At ±5 V supply, it delivers ±4.85 V output with ±200 µA load current and ±4.25 V with ±1 mA - confirming robust drive capability. For heavier loads (>5 mA), output swing degrades predictably per the VOH/VOL specs in Section 6.8 of the datasheet, and thermal limits must be observed per RθJA = 111.6°C/W for the PW package.
Is the TLC2274AIPWR pin-compatible with other devices in the TLC227x family?
Yes, the TLC2274AIPWR shares identical pinout and footprint with all TLC2274 variants in the 14-pin TSSOP (PW) package, including TLC2274IPWR, TLC2274MIPWR, and TLC2274AMIPWR. This allows direct substitution within the same package type without PCB modification, provided the application can accommodate differences in input offset voltage, temperature grade, or radiation tolerance.
