Descripción general

Description

OPA2349UA/2K5 is TI’s dual precision op-amp. It combines rail-to-rail input and output with low offset and low bias current, making it suitable for high-precision signal conditioning on a single supply. Key points:
- Dual op-amp, unity-gain stable
- Wide single-supply range (about 2.7–5.5 V)
- Low input offset, low bias current, and low noise
- Rails-to-rails on input/output
- RoHS-compliant, available in small 8-pin packages
The suffix UA/2K5 denotes a specific package/variant and temperature/lot code used by TI; exact package type (e.g., MSOP/VSSOP-8) and temperature rating can vary. For exact electrical specs, package details, and ordering information, check the TI datasheet and the “Ordering Information” section on TI.com.

Features

Key features of the OPA2349UA/2K5 (Texas Instruments):
- Ultra-low offset and drift (zero-drift/chopper-stabilized) precision op-amp
- Rail-to-rail input and rail-to-rail output (RRIO)
- Very low input bias current and low noise
- Low quiescent current (suitable for battery-powered apps)
- Wide single-supply operation (suitable for low-voltage systems)
- Unity-gain stable and suitable for precision amplification
- Wide temperature range (industrial-grade)
- Available in 8-pin MSOP/VSSOP (UA) package (2K5 variant)
- General-purpose precision device ideal for sensors, DAC outputs, DAC/ADC front-ends, and instrumentation
Note: exact electrical numbers (offset voltage, drift, GBW, bias current, supply range) are in the datasheet and vary by part revision.

Package

8-pin MSOP package (MSOP-8).

Pinout

- Pin count: 8 pins (MSOP-8/TSSOP-8 package, variant UA/2K5).
- Function: Dual precision operational amplifiers in one package (two identical op-amps, low offset/drift; pins typical: 1 OUTA, 2 −IN A, 3 +IN A, 4 V−, 5 +IN B, 6 −IN B, 7 OUTB, 8 V+).

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI)
- What kind of company: An American multinational semiconductor company based in Dallas, Texas, designing and manufacturing analog and mixed-signal integrated circuits (op-amps, ADCs/DACs, sensors, embedded processors, etc.).

Application

OPA2349UA/2K5 is a dual zero-drift, chopper-stabilized op-amp with rail-to-rail I/O, ideal for precision, single-supply circuits. Typical applications:
- Sensor signal conditioning (strain gauges, RTDs, thermocouples, pressure sensors)
- Photodiode/transimpedance and optical detector front ends
- Low-drift ADC/DAC front ends and DC servo/offset calibration
- Medical and portable instrumentation
- Battery-powered systems needing high accuracy and low drift

Equivalent

Equivalent parts (dual, low-offset, RR I/O op-amps with similar supply range):
- Analog Devices ADA4528-2 (dual zero-drift)
- TI OPA2333; TI OPA2376
Note: verify pinout and exact supply range for a true drop-in replacement.
