Key Features
- Dual voltage-feedback op-amp with 95 dB typical CMRR enabling high-precision differential signal amplification in noisy industrial environments
- Wide ±16 V (32 V total) supply range with -40°C to 125°C operating temperature, suited for automotive and industrial measurement systems
- Compact 8-pin HVSSOP with exposed thermal pad for improved power dissipation in space-constrained high-speed analog signal chains
Applications
The THS4032IDGNRG4 is designed for industrial instrumentation amplifiers, data acquisition front-ends, and medical signal conditioning circuits requiring dual op-amp channels with high CMRR on wide supply rails. Its ±16 V supply capability and industrial temperature range make it appropriate for motor drive current sensing, bridge sensor amplification, and 4-20 mA industrial loop interfaces. The package's exposed pad aids thermal management in compact designs where both op-amp channels are simultaneously driving low-impedance loads.

Frequently Asked Questions
What CMRR does THS4032IDGNRG4 provide and why does this benefit differential signal amplification?
THS4032IDGNRG4 provides a minimum CMRR of 80 dB and a typical CMRR of 95 dB. High CMRR means the amplifier rejects common-mode noise, such as 50 Hz or 60 Hz mains interference coupled onto both inputs equally, by at least 80 dB relative to the differential signal. This is critical for amplifying small differential signals from bridge sensors, thermocouples, or shunt resistors in electrically noisy industrial and motor-drive environments.
What supply voltage range does THS4032IDGNRG4 support and how does this compare to standard 5 V op-amps?
THS4032IDGNRG4 operates from a dual supply of ±16 V, giving a total supply span of 32 V, which is considerably wider than the 5 V single-supply range of low-voltage CMOS op-amps. This wide range allows the amplifier to be used directly on ±12 V industrial analog rails or ±15 V lab instrument supplies without level-shifting, enabling larger signal swings and higher dynamic range in instrumentation and test equipment designs.
How does the bias current specification of THS4032IDGNRG4 affect source impedance selection in a precision circuit?
THS4032IDGNRG4 has a maximum bias current of 6 µA at 25°C. When the source impedance is 10 kΩ, this bias current creates an input voltage error of up to 60 mV (6 µA × 10 kΩ), which may be unacceptable in precision applications. To minimise this error, designers should keep source and feedback impedances below 1 kΩ, or use matched impedances on both inputs to cancel the bias-current-induced offset voltage.
For a current-sensing circuit in an industrial motor drive, is THS4032IDGNRG4 a good fit?
Yes. THS4032IDGNRG4 is well suited for shunt-based current sensing on motor drives. The ±16 V supply accommodates the common-mode voltages present in H-bridge sensing applications, and the 80 dB minimum CMRR rejects the high common-mode noise generated by PWM switching at frequencies typically from 10 kHz to 100 kHz. Its -40°C to 125°C operating range also covers the thermal environment near motor drive inverter stages.
