Product details
Overview
8102306CA from Texas Instruments is a dual JFET-input operational amplifier in SOIC-8 package, delivering 13 V/μs slew rate, 3 MHz unity-gain bandwidth, and 18 nV/√Hz input voltage noise at 1 kHz. It features low input bias current (65 pA typ), high input impedance (10¹² Ω), and rail-to-rail common-mode input range including VCC+. It is used in audio pre-amplification, oscilloscope front-ends, and motor control signal conditioning.
For engineers reviewing the 8102306CA datasheet, 8102306CA pinout, 8102306CA application, or 8102306CA equivalent, this page provides verified specifications, validated pin functions, real-world use cases, and confirmed alternative parts for TL072-family design continuity and sourcing flexibility.
Technical Context
The 8102306CA implements a two-stage JFET-input op-amp architecture with internal frequency compensation and latch-up-free bipolar-JFET monolithic process. Its differential pair uses matched high-voltage JFETs for ultra-low input bias current and low offset drift.
It supports ±5 V to ±15 V dual-supply operation, delivers ±12 V output swing into 10 kΩ, and maintains ≥70 dB CMRR and PSRR across 0°C–70°C. Input stage includes ESD protection diodes rated for ±2000 V HBM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 13 V/μs typical - enables clean amplification of fast audio transients and control-loop signals without slew-induced distortion |
| Unity-Gain Bandwidth | 3 MHz - supports stable closed-loop operation up to ~2.5 MHz with gain ≥1, suitable for active filters and instrumentation |
| Input Voltage Noise | 18 nV/√Hz @ 1 kHz - ensures minimal added noise in low-level sensor and microphone preamp stages |
| Input Bias Current | 65 pA typical at 25°C - preserves signal integrity in high-impedance source networks (e.g., piezo sensors, photodiode amps) |
| Common-Mode Range | VCC– – 0.3 V to VCC+ - allows input signals to swing to positive rail, simplifying level-shifting in single-supply derived systems |
| Supply Current per Amp | 1.4–2.5 mA - enables dual-channel operation under 5 mA total, supporting low-power portable and battery-backed designs |
| Output Short-Circuit Protection | Yes - permits safe operation during transient overloads or miswiring without device failure |
Pinout & Package
8102306CA is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 3.90 mm, with standard JEDEC MS-012AC footprint and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives external load or next stage; capable of ±12 V swing into 10 kΩ |
| 2 | 1IN– | Inverting input of first amplifier - accepts feedback network for precise gain configuration |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference, sensor, or signal source with minimal loading |
| 4 | VCC– | Negative supply rail - must be decoupled locally to suppress ground bounce and supply noise |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from first channel; supports independent signal paths |
| 6 | 2IN– | Inverting input of second amplifier - used for differential gain, summing, or active filtering configurations |
| 7 | 2OUT | Output of second amplifier - fully independent output stage; crosstalk attenuation ≥120 dB at AVD = 100 |
| 8 | VCC+ | Positive supply rail - requires local 0.1 μF ceramic decoupling adjacent to pin for stability |

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 |
|---|---|---|---|
| TL072CDR | Identical electrical specs and pinout; same SOIC-8 package; identical 3 MHz GBW and 13 V/μs slew rate | No functional difference - direct drop-in replacement with identical thermal and layout compatibility | Select when requiring TI's standard commercial-grade (C-temp, 0°C–70°C) qualification and full traceability |
| RC4558DR | Bipolar input (not JFET); higher input bias current (500 nA vs. 65 pA); lower slew rate (1.7 V/μs); no rail-inclusive CMVR | Not suitable for high-Z sensor interfaces or rail-to-rail input applications; acceptable only in cost-sensitive, low-performance analog stages | Choose only if budget constraints outweigh performance requirements and input impedance >1 MΩ is not needed |
Compared with TL072CDR, 8102306CA offers identical performance and fit but may differ in packaging date code, lot traceability, or distribution channel compliance. RC4558DR trades JFET advantages for lower cost but sacrifices noise, speed, and input stage fidelity required in precision analog signal chains.

FAQ
What is the operating temperature range for the 8102306CA?
The 8102306CA is specified for operation from 0°C to +70°C (commercial temperature grade). This range aligns with the TL072C variant per TI's SLOS080N datasheet, and all key parameters-including input offset voltage, slew rate, and bandwidth-are guaranteed across this interval under ±15 V supply conditions.
Does the 8102306CA have internal ESD protection?
Yes, the 8102306CA includes integrated ESD protection rated at ±2000 V per Human Body Model (HBM), as confirmed in Section 6.2 of the TI SLOS080N datasheet. This protection applies to all pins and supports safe handling and board assembly in standard ESD-controlled environments.
Can the 8102306CA drive a 600 Ω load?
No-the 8102306CA is not characterized to drive 600 Ω loads. Its output voltage swing degrades to ±10 V (min) into 2 kΩ loads per datasheet Section 6.10, and driving 600 Ω would exceed safe output current limits and risk thermal overload or distortion. Use a dedicated line driver or buffer stage for 600 Ω termination.
Is the 8102306CA pin-compatible with other TL072 variants?
Yes-the 8102306CA uses the standard TL072 8-pin SOIC pinout (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+), matching TL072CDR, TL072CP, and TL072ACDR. No PCB changes are required when substituting within the same package type and temperature grade.
What is the maximum supply voltage for the 8102306CA?
The absolute maximum supply voltage for the 8102306CA is 36 V total (VCC+ – VCC–), per Section 6.1 of the TI SLOS080N datasheet. Recommended operating supply is ±5 V to ±15 V (10 V–30 V total), with derating required above ±15 V to maintain thermal safety and parameter stability.
