Product details
Overview
8102301PA from Texas Instruments is a single-channel, low-power JFET-input operational amplifier designed for precision analog signal conditioning in space-constrained or power-sensitive systems. It delivers 200 µA typical supply current per amplifier, 3.5 V/µs slew rate, ±15 V supply capability, and 1 MHz unity-gain bandwidth - enabling use in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the 8102301PA datasheet, 8102301PA pinout, 8102301PA application, or 8102301PA equivalent, this page provides verified electrical specifications, validated pin assignments for the U-package variant, real-world application contexts including light detection and audio preamplification, and two functionally comparable alternatives with documented parameter differences.
Technical Context
The 8102301PA implements a monolithic JFET-input stage paired with bipolar output transistors, delivering high input impedance (10¹² Ω), low input bias current (30 pA typ), and rail-to-rail common-mode input range extending to VCC+. Its internal frequency compensation ensures stable unity-gain operation without external components.
It features offset null terminals (OFFSET N1/OFFSET N2), output short-circuit protection, and latch-up-free operation across –40°C to 85°C. The device shares identical terminal assignments with TL07x/TL08x families, enabling drop-in replacement in legacy designs where lower power consumption is required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-stage analog front-ends in sub-1 mA total system power budgets |
| Slew Rate | 3.5 V/µs typ - supports clean amplification of audio-band signals up to ~100 kHz at unity gain |
| Input Offset Voltage | 3 mV max (TL061AC grade) - allows DC-coupled sensor interfacing without frequent recalibration |
| Unity-Gain Bandwidth | 1 MHz - sufficient for anti-aliasing filters, active RC networks, and basic instrumentation amplifiers |
| Common-Mode Input Range | –12 V to +15 V (±15 V supplies) - accepts inputs beyond negative rail, simplifying level-shifting in bipolar systems |
| Input Resistance | 10¹² Ω - minimizes loading on high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes |
| CMRR | 86 dB min - rejects noise coupled onto differential sensor lines in industrial environments |
Pinout & Package
8102301PA is supplied in an 8-pin plastic DIP (P) package and also available in SOIC (D) and TSSOP (PW) variants. The U-package variant shown in the datasheet corresponds to the same pinout as standard 8-pin DIP but in flat-pack form.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OFFSET N1 | Null adjustment terminal for input offset voltage trimming via external potentiometer |
| 2 | IN– | Inverting input - high-impedance JFET node for feedback network connection |
| 3 | IN+ | Non-inverting input - accepts high-Z sensor or reference signals without loading |
| 4 | VCC– | Negative supply rail - must be connected to system ground or negative voltage source |
| 5 | NC | No internal connection - left unconnected on PCB; no routing required |
| 6 | VCC+ | Positive supply rail - supports ±15 V operation; decoupling capacitor recommended |
| 7 | OUT | Amplified output - capable of ±10 V swing into 10 kΩ load with <10% overshoot |
| 8 | OFFSET N2 | Second null terminal - completes offset trim circuit with OFFSET N1 and external resistor network |
Key Features
| Feature | Design Value |
|---|---|
| JFET input stage | 30 pA typical input bias current - preserves signal integrity from ultra-high-impedance sources like photodiodes |
| Internal frequency compensation | Stable unity-gain operation without external compensation components - reduces BOM count and layout complexity |
| Offset voltage null capability | Dual null pins (1 & 8) support <1 mV residual offset after trimming - critical for precision DC measurement paths |
| Output short-circuit protection | Unlimited duration safe short to either rail - eliminates need for external current-limiting resistors in test fixtures |
| Latch-up free design | Immune to CMOS-style latch-up under overvoltage or ESD stress - improves field reliability in uncontrolled environments |
Applications
| Photodiode Signal Conditioning | Portable Audio Preamplifier |
|---|---|
Use Scenario: Amplifying weak current from a reverse-biased photodiode in a battery-powered smoke detector. IC Role / Device Role / Timing Role: Transimpedance amplifier converting photocurrent to voltage with minimal dark-current error. Use Value: 30 pA input bias current prevents false triggering due to leakage; 200 µA supply current extends battery life to >2 years. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL061CP | Same die, plastic DIP package; 15 mV max VIO (C-grade) vs 3 mV (A-grade) | Less precise DC performance; suitable for AC-only or non-critical gain stages | Select when cost sensitivity outweighs offset-critical requirements |
| TL071CP | Higher slew rate (13 V/µs), lower noise (18 nV/√Hz), but 1.4 mA supply current | Not suitable for battery operation; preferred where speed/noise dominate power constraints | Choose only if 7× higher supply current is acceptable for improved dynamic performance |
Compared with TL061CP, 8102301PA offers tighter input offset (3 mV vs 15 mV) for DC-critical circuits; compared with TL071CP, it reduces quiescent current by 86% - making it optimal for always-on sensor nodes where µA-level sleep current matters.

FAQ
What is the maximum supply voltage rating for the 8102301PA?
The 8102301PA supports ±18 V absolute maximum supply voltage per rail, with recommended operation at ±15 V. This allows full-swing output of ±10 V into 10 kΩ loads while maintaining linearity and thermal stability across its –40°C to 85°C operating range. Exceeding ±18 V risks permanent damage to the internal JFET input stage.
Does the 8102301PA require external compensation capacitors?
No, the 8102301PA includes internal frequency compensation optimized for stable unity-gain operation. External compensation is unnecessary for standard configurations, reducing bill-of-materials count and PCB area. Only specialized high-speed or high-gain (>100) configurations may benefit from optional external compensation per TI Application Note SLOA069.
How does the 8102301PA compare to the TL071 in terms of power efficiency?
The 8102301PA draws just 200 µA per amplifier versus 1.4 mA for the TL071CP - a 86% reduction. This makes 8102301PA viable for multi-op-amp sensor nodes powered by coin cells or energy harvesters, whereas TL071 is better suited for mains-powered equipment where speed and noise performance justify higher current draw.
Can the 8102301PA drive a 600 Ω audio load directly?
No - the 8102301PA is not specified for driving low-impedance loads. Its output stage delivers ±10 V into 10 kΩ but exhibits increased distortion and reduced swing below 2 kΩ. For 600 Ω audio distribution, use a dedicated line driver (e.g., BUF634) or buffer stage; the 8102301PA should remain in high-impedance signal conditioning roles.
Is pin 5 (NC) on the 8102301PA safe to connect to ground or leave floating?
Pin 5 is explicitly designated "NC" (No internal connection) in the TI SLOS078F datasheet. It must remain unconnected - neither grounded nor tied to any voltage. Routing or soldering to this pin risks mechanical stress on the bond wire or unintended coupling; PCB layout should omit pad connection or use a non-plated through-hole.
