Product details
Overview
TLC2272AMJGB from Texas Instruments is a dual rail-to-rail output operational amplifier designed for precision signal conditioning in low-power, high-impedance sensor interfaces. It delivers 2.2-MHz gain-bandwidth, 3.6-V/µs slew rate, 9 nV/√Hz input voltage noise at 1 kHz, and ±5 V supply operation with output swing to both rails - enabling direct interfacing with 12-bit ADCs in battery-powered instrumentation.
For engineers reviewing the TLC2272AMJGB datasheet, TLC2272AMJGB pinout, TLC2272AMJGB application, or TLC2272AMJGB equivalent, key selection criteria include rail-to-rail output swing under ±5 V supplies, sub-1-mV input offset voltage (max 950 µV), ultra-low 1-pA typical input bias current, and guaranteed operation from –55°C to +125°C for military-grade reliability.
Technical Context
The TLC2272AMJGB uses Advanced LinCMOS process technology to achieve rail-to-rail output swing while maintaining low input bias current and low noise - distinct from bipolar or standard CMOS op-amps. Its common-mode input range extends to the negative rail (VDD–/GND), supporting single-supply transducer sensing without level-shifting circuitry.
It features fully specified performance across ±2.2 V to ±8 V supply ranges, with stable unity-gain operation into 100 pF capacitive loads and phase margin ≥50°. The device is characterized for both split-supply (±5 V) and single-supply (5 V) configurations, with identical AC performance metrics including 2.25-MHz gain-bandwidth product and 3.6-V/µs slew rate at TA = 25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2.2 V to ±8 V - supports wide-range industrial/military power rails and enables direct use with ±5 V legacy systems |
| Input Offset Voltage | Max 950 µV at TA = 25°C - ensures <0.1% error in 1-V full-scale precision amplification stages |
| Input Bias Current | 1 pA typical - preserves signal integrity when amplifying from >1 GΩ sources like piezoelectric sensors |
| Gain-Bandwidth Product | 2.25 MHz at ±5 V - allows stable closed-loop gain of 10 up to 225 kHz 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 applications |
| Input Voltage Noise | 9 nV/√Hz at 1 kHz - 2× lower than TLC272, critical for low-level thermocouple or strain gauge amplification |
| Operating Temperature | –55°C to +125°C - qualified per MIL-PRF-38535 for extended-life aerospace and defense deployments |
Pinout & Package
Package: 8-pin SOIC (D package), body size 3.91 mm × 4.90 mm, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - rail-to-rail capable, drives 10-kΩ load to within 15 mV of either supply rail |
| 2 | 1IN– | Inverting input, Channel 1 - high-impedance node (10¹² Ω) for feedback network connection |
| 3 | 1IN+ | Non-inverting input, Channel 1 - accepts common-mode voltages down to VDD– (negative rail) |
| 4 | VDD–/GND | Negative supply or ground reference - required for split-supply operation; ties to system ground in single-supply mode |
| 5 | 2IN+ | Non-inverting input, Channel 2 - independent of Channel 1, enables dual-sensor signal conditioning on one die |
| 6 | 2IN– | Inverting input, Channel 2 - supports differential input configuration with matched layout for CMRR >75 dB |
| 7 | 2OUT | Output of Channel 2 - electrically isolated from Channel 1; shares same rail-to-rail output capability |
| 8 | VDD+ | Positive supply - accepts up to +8 V; internal ESD protection rated to ±2000 V HBM |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives loads to within 15 mV of VDD+ and VDD– at ±5 V, eliminating need for level-shifting before ADC input |
| Low input bias current | 1-pA typical enables direct coupling to high-Z sources (e.g., pH electrodes, photodiodes) without significant DC error |
| Low-noise architecture | 9 nV/√Hz at 1 kHz reduces integrated noise in 10-Hz–10-kHz bandwidths to <1.4 µVPP - critical for sensor front-ends |
| Full military temperature qualification | Specified over –55°C to +125°C with tested long-term drift <0.002 µV/month - suitable for uncooled avionics modules |
| Macromodel included | SPICE model provided by TI enables accurate transient and AC simulation of closed-loop stability and settling behavior |

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 (0°C to +70°C), same pinout and electrical specs except wider VIO max (2.5 mV) and no MIL-spec screening | Not qualified for extended temperature or reliability testing; unsuitable for aerospace or defense deployments | Select TLC2272CDR only for cost-sensitive commercial designs where military temp range and screening are unnecessary |
| TLV2432IDR | Higher drive capability (±50 mA), wider input voltage range (rail-to-rail input), but higher noise (17 nV/√Hz) and lower GBW (2.5 MHz) | Better suited for driving heavy capacitive loads or multiplexed ADC inputs; less optimal for ultra-low-noise sensor front-ends | Choose TLV2432IDR when output current >20 mA or rail-to-rail input is required - not a drop-in replacement due to different input stage architecture |
Compared with TLC2272CDR, the TLC2272AMJGB provides tighter input offset voltage (950 µV vs 2.5 mV) and full military temperature support; versus TLV2432IDR, it trades higher output drive for lower noise and proven reliability in harsh environments - making it optimal for precision, high-reliability analog signal chains.

FAQ
What is the maximum supply voltage rating for the TLC2272AMJGB?
The TLC2272AMJGB has an absolute maximum supply voltage rating of ±8 V (16 V total). Recommended operating range is ±2.2 V to ±8 V. Exceeding ±8 V risks permanent damage. This rating is verified per Absolute Maximum Ratings table in the SLOS984 datasheet, and applies to both VDD+ and VDD– terminals referenced to each other.
Does the TLC2272AMJGB support single-supply operation?
Yes, the TLC2272AMJGB is fully specified for single-supply operation. When used with VDD+ = 5 V and VDD–/GND = 0 V, it maintains rail-to-rail output swing, common-mode input range extending to ground, and all key AC parameters (GBW, slew rate, noise) as characterized in the datasheet. Input common-mode range reaches 0 V, enabling true ground-referenced sensing.
What is the input offset voltage specification for the TLC2272AMJGB at temperature extremes?
The TLC2272AMJGB has a maximum input offset voltage of 1500 µV over the full operating range of –55°C to +125°C. At TA = 25°C, the limit is tighter: 950 µV maximum. This is explicitly stated in Section 6.5 and 6.6 of the SLOS984 datasheet under "VIO Input offset voltage" with test conditions VIC = 0 V and VO = 0 V.
Is the TLC2272AMJGB pin-compatible with the TLC272 series?
No, the TLC2272AMJGB is not pin-compatible with the TLC272. While both are dual op-amps in 8-pin SOIC packages, the TLC2272AMJGB uses a different pinout: Pin 4 is VDD–/GND (not NC), and Pins 1–3, 5–8 match functional roles but differ from TLC272's NC placements. Direct replacement requires PCB redesign. The datasheet explicitly positions TLC2272AM-MIL as a *performance upgrade*, not a drop-in replacement.
What thermal metrics apply to the TLC2272AMJGB in SOIC (D) package?
For the TLC2272AMJGB in 8-pin SOIC (D) package, the junction-to-ambient thermal resistance (RθJA) is 115.6°C/W, and junction-to-board (RθJB) is 55.9°C/W. These values are measured per JEDEC JESD51-7 and appear in Section 6.4 of the SLOS984 datasheet. No RθJC(bot) is specified for the D package - only top-side characterization (ψJT = 14.3°C/W) is provided.
