Product details
Overview
TL092CPSR from Texas Instruments is a dual JFET-input operational amplifier in an 8-pin SOIC (PS) package, rated for 0°C to 70°C operation. It features 10¹² Ω typical input impedance, ±36 V absolute max supply range, ±13.5 V peak output swing (at ±15 V), 1 MHz unity-gain bandwidth, and Class AB output stage - used in precision analog signal conditioning, sensor interfacing, and industrial instrumentation.
For engineers reviewing the TL092CPSR datasheet, TL092CPSR pinout, TL092CPSR application, or TL092CPSR equivalent, key selection criteria include input bias current (200 pA typ), common-mode input range extending to VCC−, short-circuit protection, and single-supply compatibility down to 3 V.
Technical Context
The TL092CPSR integrates two independent high-impedance N-channel-JFET input stages with internal frequency compensation and Class AB output stages. Its input common-mode range includes the negative rail (VCC−), enabling true single-supply operation without level-shifting circuitry.
It delivers 1 MHz unity-gain bandwidth and 0.6 V/µs slew rate under ±15 V supplies, with 70–90 dB CMRR and PSRR across its 3 V to 36 V total supply range. Output swing reaches VCC− to (VCC+ − 1.3 V) into 2 kΩ loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3 V to 36 V total (single or dual); enables direct interface with 3.3 V, 5 V, 12 V, and 24 V systems. |
| Input Impedance | 10¹² Ω typical; minimizes loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Input Bias Current | 200 pA typical at 25°C; critical for low-leakage integrators and precision current-to-voltage conversion. |
| Output Swing | VCC− to (VCC+ − 1.3 V) into 2 kΩ; supports rail-to-rail-compatible signal chains without external level shifters. |
| Unity-Gain Bandwidth | 1 MHz; sufficient for audio preamps, active filters up to ~100 kHz, and medium-speed sensor amplification. |
| Slew Rate | 0.6 V/µs; limits large-signal fidelity but ensures stability with capacitive loads up to 200 pF. |
| Operating Temperature | 0°C to 70°C ambient; qualified for commercial-grade industrial control and test equipment environments. |
Pinout & Package
The TL092CPSR is housed in an 8-pin plastic small-outline (SOIC-PS) package, tape-and-reel packaged (2000 units/reel), RoHS-compliant with NiPdAu lead finish and MSL Level-1 rating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (1OUT) | Amplifier 1 output | Class AB buffered output capable of ±40 mA short-circuit current; drives 2 kΩ loads to full specified swing. |
| 2 (1IN−) | Amplifier 1 inverting input | High-impedance FET node; accepts differential signals referenced to VCC− or mid-supply in single-ended configurations. |
| 3 (1IN+) | Amplifier 1 noninverting input | Matches 1IN− in impedance and offset; supports unity-gain buffers and precision summing junctions. |
| 4 (VCC−) | Negative supply / ground reference | Common return for both amplifiers; input common-mode range extends to this pin, enabling true single-supply use. |
| 5 (2IN+) | Amplifier 2 noninverting input | Independent high-Z input; allows dual-channel signal processing without crosstalk (120 dB channel separation at 1–20 kHz). |
| 6 (2IN−) | Amplifier 2 inverting input | Electrically identical to 1IN−; supports differential pair configurations or independent gain stages. |
| 7 (2OUT) | Amplifier 2 output | Matched performance to 1OUT; enables dual-path filtering, instrumentation front-ends, or stereo audio buffering. |
| 8 (VCC+) | Positive supply | Accepts up to +18 V (or total 36 V differential); internal protection prevents latch-up during supply sequencing. |
Key Features
| Feature | Design Value |
|---|---|
| High-impedance JFET input | 10¹² Ω typical input resistance enables direct connection to megohm-level sensor elements without signal degradation. |
| Input common-mode range to VCC− | Eliminates need for negative supply or input biasing networks in single-supply systems (e.g., 5 V microcontroller interfaces). |
| Internal frequency compensation | Ensures stable unity-gain operation without external compensation components - simplifies PCB layout and BOM. |
| Short-circuit protection | Withstands indefinite output shorts to VCC− or VCC+ without damage, improving system robustness in field-deployed equipment. |
| Low input offset current | 50 pA typical offset current minimizes error in high-gain transimpedance amplifiers using photodiodes or electrochemical sensors. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL082CDR | Lower input bias current (30 pA typ), higher slew rate (13 V/µs), same PS package and pinout. | Better for high-speed precision applications (e.g., active filters >100 kHz); requires tighter layout due to higher bandwidth. | Select TL082CDR when higher speed and lower bias current outweigh cost sensitivity. |
| MC3403DR2G | Bipolar input (vs. JFET), higher input bias current (250 nA typ), wider temp range (−40°C to 85°C), same pinout. | More suitable for automotive or extended-temp industrial use; less ideal for ultra-high-Z sensor interfaces. | Choose MC3403DR2G for cost-sensitive designs requiring extended temperature support and moderate input impedance. |
Compared with TL092CPSR, TL082CDR offers superior speed and input bias performance but demands stricter stability controls, while MC3403DR2G trades input impedance for broader temperature capability and bipolar robustness - making TL092CPSR optimal for balanced commercial-grade analog signal conditioning where JFET input advantages are essential.

FAQ
What is the maximum supply voltage rating for the TL092CPSR?
The TL092CPSR has an absolute maximum supply voltage rating of ±18 V per rail, or a total differential supply of 36 V. Operation beyond these limits risks permanent damage. Recommended operating supply is 3 V to 36 V total, supporting single-supply (e.g., 5 V or 12 V) and split-supply (±5 V, ±15 V) configurations. The TL092CPSR must never be subjected to differential voltages exceeding 36 V or individual rail voltages beyond ±18 V.
Does the TL092CPSR support true single-supply operation with input signals referenced to ground?
Yes, the TL092CPSR supports true single-supply operation because its input common-mode voltage range explicitly includes VCC−, allowing inputs to be referenced directly to ground when VCC− = 0 V. This eliminates the need for input biasing networks or virtual grounds in 3.3 V or 5 V systems. The TL092CPSR maintains specified performance (e.g., input offset, CMRR) across this extended range, making it suitable for sensor interfaces and microcontroller-connected analog front-ends.
What is the output voltage swing capability of the TL092CPSR under ±15 V supplies?
Under ±15 V supplies, the TL092CPSR delivers a peak-to-peak output voltage swing of ±13.5 V into a 10 kΩ load and ±13 V into a 2 kΩ load, meaning it swings from approximately −15 V to +13.7 V (VCC− to VCC+ − 1.3 V). This asymmetric swing reflects its Class AB output stage design. The TL092CPSR does not achieve rail-to-rail output but provides usable dynamic range for most industrial and audio applications without requiring additional level-shifting circuitry.
Is the TL092CPSR pin-compatible with other dual op-amps in SOIC-8 packages?
Yes, the TL092CPSR uses the industry-standard SOIC-8 (PS) pinout shared by many dual op-amps including TL082, MC3403, and LM358 variants. Pin 1 is output of amplifier 1, pins 2 and 3 are its inverting and noninverting inputs, pin 4 is VCC−, pins 5 and 6 are amplifier 2's noninverting and inverting inputs, pin 7 is amplifier 2's output, and pin 8 is VCC+. However, electrical differences (e.g., input stage type, bias current, slew rate) mean functional substitution requires validation - the TL092CPSR is not a drop-in replacement for all SOIC-8 dual op-amps.
What thermal and packaging specifications apply to the TL092CPSR?
The TL092CPSR is packaged in an 8-pin plastic small-outline (PS) package with a thermal impedance (θJA) of 95°C/W, RoHS-compliant NiPdAu lead finish, and JEDEC MSL Level-1 rating (unlimited floor life at ≤30°C/60% RH). It ships in tape-and-reel format (2000 units/reel) with reel diameter 330 mm and width 16.4 mm. The TL092CPSR operates from 0°C to 70°C and is characterized for reliability under standard commercial conditions, with storage temperature ranging from −65°C to +150°C.
