概述

Description

OPA4130UA is TI’s dual operational amplifier (OPA4130 family), offered in an 8-pin package (UA suffix indicates the packaging). It’s designed for precision amplification with very low input offset voltage and bias current, low noise, and good DC accuracy, making it suitable for instrumentation, sensor front-ends, active filters, and buffer stages. The device typically supports a wide supply range and stable operation across common-mode ranges, useful in single- and dual-supply designs. Applications include precision gain stages, DAC/ADC conditioning, and audio front-ends.
Notes:
- Check the exact specifications (offset, bias current, GBW, slew rate, input common-mode range, supply limits, temperature range) in the TI OPA4130 datasheet for the specific -UA variant you’re using.

Features

Here are the typical features of the TI OPA4130UA:
- Precision, low-noise operational amplifier
- Ultra-low input offset voltage and bias current
- Low voltage noise density
- Unity-gain stable
- High gain-bandwidth product and fast slew rate
- Wide supply voltage range (suitable for single-supply operation)
- High open-loop gain with good DC accuracy
- Strong PSRR and CMRR
- Robust output drive for moderate loads
- Available in UA package (e.g., SOIC-8) for easy PCB mounting
Note: for exact electrical numbers (offset, bias current, GBW, slew rate, supply range), consult the official datasheet.

Package

OPA4130UA comes in an 8-pin small-outline IC: SOIC-8 package.

Pinout

- Pin count: 8 pins (dual op-amp in an 8-pin package such as SOIC-8).
- Function: Dual operational amplifiers. Each amplifier has non-inverting and inverting inputs and an output; plus power pins. Typical pinout (for OPA4130UA): Pin1 = Output A, Pin2 = Inverting input A, Pin3 = Non-inverting input A, Pin4 = V−, Pin5 = Non-inverting input B, Pin6 = Inverting input B, Pin7 = Output B, Pin8 = V+.

Manufacturer

- Manufacturer: Texas Instruments (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog and mixed-signal ICs, sensors, and embedded processing products.

Application

OPA4130UA application areas:
- Precision sensor signal conditioning
- Transimpedance amplifiers for photodiodes
- Active filters and high-speed front-end
- Instrumentation/ADC driver stages
- Audio front-end preamplifiers
- Servo and control-loop circuits
- Test and measurement equipment

Equivalent

Do you want a pin-for-pin cross-reference in the same UA package, or any functional equivalent from TI or other vendors? Please provide key specs: supply voltage, bandwidth/GBW, slew rate, input noise, input bias current, rail-to-rail IO, and operating temperature.
