Product details
Overview
8102302HA from Texas Instruments is a single-channel, low-power JFET-input operational amplifier in the TL06x family. It delivers 200 µA typical supply current per amplifier, ±11 V to ±15 V common-mode input range, and 3.5 V/µs slew rate - enabling precision signal conditioning in battery-powered instrumentation and sensor interfaces.
For engineers reviewing the 8102302HA datasheet, 8102302HA pinout, 8102302HA application, or 8102302HA equivalent, this page provides verified technical context, pin-level design meaning, real-world use cases, and validated alternative options for low-power analog signal chains.
Technical Context
The 8102302HA implements a high-impedance JFET differential input stage with internal frequency compensation, supporting stable unity-gain operation. Its input bias current remains below 200 pA at 25°C and features rail-to-rail common-mode input voltage range extending to within 4 V of either supply rail.
It integrates offset null terminals (OFFSET N1 and OFFSET N2) for precision DC-coupled applications and includes output short-circuit protection. The device operates across ±5 V to ±15 V dual supplies and supports full industrial temperature range (–40°C to +85°C) per TL061I specification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA typical per amplifier - enables multi-stage analog front-ends in energy-constrained systems |
| Input Offset Voltage | 3 mV max at 25°C - supports accurate DC amplification without external trimming in most sensor interfaces |
| Slew Rate | 3.5 V/µs typical - sufficient for audio-band and medium-speed control loop signals |
| Common-Mode Range | ±11 V to ±15 V - allows direct interfacing with ±12 V transducers and industrial sensors |
| Input Impedance | 10¹² Ω - minimizes loading on high-Z sources like piezoelectric sensors and pH electrodes |
| CMRR | 86 dB typical - rejects power-supply noise and shared interference in noisy environments |
| Unity-Gain Bandwidth | 1 MHz - sets usable small-signal bandwidth limit for gain ≥1 configurations |
Pinout & Package
8102302HA is packaged in an 8-pin SOIC (D package), measuring 4.9 mm × 3.9 mm, with standard JEDEC MS-012 outline and 1.27 mm pitch.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL061CDR | Same electrical specs; SOIC-8 package with Pb-free finish and tape-and-reel packaging | Identical performance; optimized for automated SMT assembly | Select when requiring RoHS-compliant, volume-ready packaging |
| TL071CP | Higher slew rate (13 V/µs), higher supply current (2.5 mA), no offset null pins | Better for wideband AC-coupled applications; unsuitable for precision DC calibration | Select when bandwidth >1 MHz and offset trimming is unnecessary |
Compared with TL061CDR, 8102302HA offers identical core performance but may differ in packaging format and reel specifications; compared with TL071CP, 8102302HA trades bandwidth and speed for ultra-low power and offset adjustability - making it preferable for DC-accurate, battery-operated systems.

FAQ
What is the operating temperature range for 8102302HA?
The 8102302HA is rated for industrial temperature operation from –40°C to +85°C, matching the TL061I specification. This range ensures reliable performance in factory automation, outdoor instrumentation, and automotive cabin electronics where ambient conditions vary widely. All key parameters-including input offset voltage, supply current, and CMRR-are guaranteed across this full range per the official TI datasheet SLOS078L.
Does 8102302HA include internal frequency compensation?
Yes, 8102302HA includes internal frequency compensation, enabling stable unity-gain operation without external components. This is confirmed in the TI datasheet section 8.1 and functional block diagram. The compensation ensures phase margin >45° under standard load conditions (RL ≥ 2 kΩ, CL ≤ 100 pF), making 8102302HA suitable for general-purpose inverting/non-inverting amplifier designs without stability analysis overhead.
Can 8102302HA be used with single-supply operation?
Yes, 8102302HA supports single-supply operation when biased appropriately-e.g., with VCC+ = +10 V and VCC− = 0 V-and input common-mode voltage referenced to mid-supply. Its common-mode input range extends to within 4 V of either rail, so with a +10 V supply, inputs can swing from +4 V to +6 V. Output swing remains limited to ~±3 V around the bias point; full-rail output requires rail-to-rail op-amps not offered by the TL06x series.
What is the purpose of OFFSET N1 and OFFSET N2 pins on 8102302HA?
The OFFSET N1 and OFFSET N2 pins on 8102302HA provide dedicated access to the internal input stage nulling network, allowing external adjustment of input offset voltage to <1 mV. As shown in Figure 18 of the TI datasheet, a 100 kΩ potentiometer is connected between these pins, with its wiper tied to VCC−. This feature enables precision DC calibration in applications like strain gauge amplifiers and medical sensor front-ends where zero-point drift must be minimized.
How does 8102302HA compare to TL081 in terms of power and performance?
8102302HA is the low-power variant of the TL081: it draws only 200 µA versus TL081's 1.4 mA supply current, trading 4× higher slew rate (13 V/µs) and wider bandwidth for >90% power reduction. Both share identical pinout and JFET input architecture, but 8102302HA's lower bias current (<200 pA vs ~30 pA for TL081) and offset null capability make it better suited for ultra-low-power, high-precision DC applications - whereas TL081 excels in AC-coupled, wideband signal paths.
