Key Features
- Dual op-amp configuration with ultra-low 0.2 nA input bias current at 25°C enabling high-impedance sensor interfaces with minimal loading
- Wide ±15V supply voltage operation providing full rail-to-rail headroom for industrial measurement and audio signal conditioning
- High common-mode rejection ratio of 70 dB minimum (87 dB typical) for superior noise rejection in differential measurement circuits
- 8-pin SOIC surface-mount package with internal frequency compensation for compact PCB layouts in industrial and instrumentation designs
Applications
The TL032IDG4 is suited for precision instrumentation amplifiers, active filter stages, and differential signal conditioning in industrial measurement equipment where dual op-amp channels and wide supply rails are required. Its ultra-low bias current of 0.2 nA at 25°C makes it ideal for high-impedance sensor interfaces such as pH probes, piezoelectric transducers, and capacitive pressure sensors. The ±15V supply capability and high CMRR also make it a reliable choice for audio signal processing, medical equipment front-ends, and data acquisition system buffer stages.

Frequently Asked Questions
What is the TL032IDG4 and how many amplifier channels does it contain?
The TL032IDG4 is a dual general-purpose operational amplifier from Texas Instruments, containing two independent voltage-feedback op-amp channels in a single 8-pin SOIC package. Both channels share the same power supply pins, making it a compact and cost-effective solution when two independent amplifier stages are needed on the same PCB.
What is the supply voltage range for the TL032IDG4?
The TL032IDG4 is rated for ±15V dual supply operation, which provides a total supply span of 30V. This wide supply range is standard for industrial and precision analog instrumentation where large signal swings are needed and is compatible with legacy analog system power rails commonly found in test equipment, industrial controllers, and analog computing circuits.
What is the input bias current specification of the TL032IDG4?
The TL032IDG4 has an input bias current (IIB) of 0.2 nA maximum at 25°C and 0.9 nA maximum over the full temperature range. These ultra-low values make it suitable for interfacing with high-impedance signal sources such as photodiodes, electrochemical sensors, and capacitive transducers where even small leakage currents would cause unacceptable voltage errors.
What package does the TL032IDG4 come in?
The TL032IDG4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package, corresponding to JESD-30 code R-PDSO-G8. It is supplied in tube packaging as indicated by the 'D' designator. The G4 suffix confirms RoHS compliance and lead-free construction per Texas Instruments' green packaging standards.
What are common applications for the TL032IDG4?
Common applications include precision differential amplifiers for bridge sensor readout, two-stage active filter designs (e.g., Sallen-Key or multiple feedback topologies), photodiode transimpedance amplifiers, sample-and-hold circuits, and general-purpose analog signal conditioning in industrial automation, medical devices, and scientific instruments where low bias current and stable ±15V operation are required.
