Product details
Overview
TLC2272AMFKB from Texas Instruments is a dual rail-to-rail output operational amplifier in LCCC-20 package, delivering 2.25 MHz gain-bandwidth, 3.6 V/µs slew rate, and 9 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in low-power, high-impedance sensor interfaces such as piezoelectric transducers.
For engineers reviewing the TLC2272AMFKB datasheet, TLC2272AMFKB pinout, TLC2272AMFKB application, or TLC2272AMFKB equivalent, key selection criteria include its ±5 V operation, 950 µV max input offset voltage at 25°C, rail-to-rail output swing (±4.85 V at ±5 V supplies), low 1 pA typical input bias current, and MIL-spec temperature range (–55°C to +125°C).
Technical Context
The TLC2272AMFKB uses Advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise. Its fully differential input stage supports common-mode input voltage down to VDD− (including negative rail) and up to VDD+ − 1.5 V, enabling direct interfacing with single-supply ADCs and transducer front-ends.
It features internal frequency compensation for unity-gain stability with 10 kΩ load and 100 pF capacitive load, delivering 52° phase margin and 10 dB gain margin. The device is characterized across ±2.2 V to ±8 V supply range and operates reliably under MIL-STD-883 conditions.
Key Specifications

|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide industrial and military power rails including ±5 V standard operation |
| Gain-Bandwidth Product | 2.25 MHz at ±5 V - enables stable closed-loop gain up to ~20 at 100 kHz for precision filtering |
| Slew Rate | 3.6 V/µs typical at ±5 V - supports 2.3 V step response settling within 3.2 µs to 0.01% for fast pulse conditioning |
| Input Offset Voltage | 950 µV max at 25°C - ensures ≤0.02% error in 5 V full-scale instrumentation amplifiers |
| Input Bias Current | 1 pA typical at 25°C - preserves signal integrity in >1 GΩ source impedance applications (e.g., pH electrodes) |
| Output Swing (±5 V) | ±4.85 V at ±200 µA load - delivers >97% rail utilization for maximum dynamic range into 10 kΩ loads |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than TLC272, critical for low-level sensor signal amplification |
Pinout & Package

|---|---|---|
| 1, 3, 4, 6, 8, 9, 11, 13, 14, 16, 18, 19 | No Connection (NC) | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling |

| 12 | 2IN+ | Non-inverting input, Channel 2 - independent of Channel 1; supports dual-path signal processing |
| 15 | 2IN– | Inverting input, Channel 2 - enables differential configuration or independent gain setting |
| 17 | 2OUT | Amplifier Channel 2 output - electrically isolated from Channel 1; same rail-to-rail performance |
| 20 | VDD+ | Positive supply terminal - highest potential rail; decoupling capacitor required within 5 mm |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272CDR | Commercial-grade SOIC-8; 950 µV VIO max, but only rated –40°C to +85°C; no MIL qualification | Cost-sensitive industrial designs without extended temperature or reliability requirements | Select when MIL-PRF-38535 compliance and –55°C operation are not required |
| TLV2432IDR | Higher drive capability (±50 mA), wider input voltage range (to VDD±), but higher noise (21 nV/√Hz) and 1.2 mV VIO max | Applications needing stronger output drive into heavy capacitive loads or wider input common-mode range | Select when output current >±5 mA or input CMVR beyond VDD± −1.5 V is needed |
Compared with TLC2272CDR, TLC2272AMFKB provides guaranteed military temperature range and hermetic packaging at higher cost; compared with TLV2432IDR, it trades output drive and input range for lower noise and bias current - making it optimal for high-precision, low-power, high-impedance sensing.

FAQ
What is the maximum operating supply voltage for the TLC2272AMFKB?
The TLC2272AMFKB supports a supply voltage range of ±2.2 V to ±8 V. Absolute maximum ratings specify ±8 V on VDD+ and VDD– terminals. Operation beyond ±8 V risks permanent damage. For reliable long-term use, TI recommends staying within ±2.2 V to ±8 V as defined in Recommended Operating Conditions - with full electrical characterization provided at ±5 V and 5 V single-supply configurations in the datasheet.
Does the TLC2272AMFKB support single-supply operation?
Yes, the TLC2272AMFKB is fully specified for single-supply operation. It functions correctly with VDD+ = 5 V and VDD–/GND = 0 V, and its common-mode input voltage range extends to the negative rail (0 V). The rail-to-rail output swing allows output voltages within 15 mV of either rail under light load, making it ideal for interfacing with 5 V ADCs and microcontrollers without level-shifting circuitry.
What is the input offset voltage specification for TLC2272AMFKB at temperature extremes?
The TLC2272AMFKB has a maximum input offset voltage of 1500 µV over the full operating temperature range of –55°C to +125°C. At 25°C, the limit is tighter: 950 µV maximum. This is verified per MIL-PRF-38535 Class K testing, and the temperature coefficient is specified at 2 µV/°C - enabling accurate error budgeting in precision instrumentation designs across military temperature ranges.
Is the TLC2272AMFKB pin-compatible with the commercial TLC2272CDR?
No, the TLC2272AMFKB (LCCC-20) is not pin-compatible with the TLC2272CDR (SOIC-8). They differ in package type, pin count, and pin assignment: TLC2272AMFKB uses a 20-pin ceramic flatpack with multiple NC pins and dedicated supply terminals, while TLC2272CDR uses an 8-pin SOIC with shared supply pins and no NCs. PCB redesign and layout changes are required for substitution.
What thermal metrics apply to the TLC2272AMFKB in LCCC-20 package?
For the TLC2272AMFKB in FK (LCCC-20) package, the datasheet specifies RθJC(bot) = 8.68°C/W (junction-to-case bottom), RθJC(top) = 121.3°C/W, and ψJB = 55.4°C/W (junction-to-board). These values reflect its ceramic hermetic construction and require conduction cooling via the bottom surface. Unlike plastic packages, LCCC relies on board-level thermal vias and copper area under the package body to manage power dissipation effectively.
