Typical Applications
OPA2375IPWR is suitable for 6 applications: Transducer and Sensor Signal Conditioning, Industrial Analog Front Ends, Active Filter Networks, Medical and Diagnostic Instrumentation, Portable and Battery-Powered Devices, Photodiode Transimpedance Amplification.
Transducer and Sensor Signal Conditioning
The OPA2375's 4.6 nV/√Hz noise and 500 μV maximum offset make it well suited for amplifying low-level sensor signals such as thermocouples, strain gauges, and pressure bridges. Its CMOS inputs draw negligible bias current, preserving accuracy with high-impedance sources. Configured as a non-inverting gain stage between the sensor and an ADC, the 10 MHz bandwidth provides ample loop gain for low distortion, while rail-to-rail output maximizes ADC input dynamic range in 3.3 V and 5 V systems.
Recommended
Industrial Analog Front Ends
In factory automation, PLC analog inputs, and 4-20 mA loop conditioning, the OPA2375's DC precision (500 μV offset max) and rail-to-rail output allow accurate conversion of transducer signals to controller ADC inputs. The 10 MHz bandwidth supports anti-alias filtering stages ahead of precision converters, and the dual channel integrates a filter and gain stage in one TSSOP-8 or SOIC-8 footprint, reducing BOM count. Its 5.5 V maximum supply maps directly onto standard industrial 5 V analog rails.
Recommended
Active Filter Networks
With 10 MHz gain-bandwidth, the OPA2375 easily implements Sallen-Key and multiple-feedback active filters at audio and intermediate frequencies, where op-amp bandwidth must exceed the corner frequency by 50-100x to avoid Q enhancement and phase error. Its low noise keeps the filter's noise contribution below that of the source impedance, and the RRO output maintains maximum headroom. Dual channels in one package let designers realize two filter poles or stages compactly.
Recommended
Medical and Diagnostic Instrumentation
Medical monitoring and diagnostic equipment demand low-noise, DC-accurate signal chains for biosensor and photodiode interfaces. The OPA2375's 4.6 nV/√Hz broadband noise minimizes the analog noise floor, while its low CMOS input bias current suits high-impedance electrodes. Powered from a single 5 V rail, the rail-to-rail output preserves resolution into 12- to 24-bit converters. The dual configuration supports both a preamplifier and a second-stage filter from a single TSSOP-8 device, saving board area in portable instruments.
Recommended
Portable and Battery-Powered Devices
For portable, battery-operated equipment, the OPA2375 operates from a single lithium-ion cell stack or 3.3 V rail up to 5.5 V, and its CMOS design delivers low quiescent power consumption. The rail-to-rail output stage uses the full supply span, important when signal swings approach battery voltage limits. Available in tiny VSSOP-8 and X2QFN packages, the dual amplifier consolidates gain and buffer functions into minimal PCB area for wearables, handheld meters, and IoT sensor nodes.
Recommended
Photodiode Transimpedance Amplification
Optical receivers and light-measurement systems require a low-noise transimpedance amplifier. The OPA2375's low input noise and low CMOS bias current make it a solid choice for mid-bandwidth TIA stages, converting photodiode current to voltage with high fidelity. Its 10 MHz bandwidth supports fast optical signals, and the RRO output allows maximum signal utilization on low supply rails. Careful feedback resistor selection and layout parasitic compensation keep the TIA stable with diode capacitance.

Key Differentiators
- Lower noise at same bandwidth (vs AD8606ARZ)
- Lower noise than OPA2192IDR (vs OPA2192IDR)
- DC precision on CMOS (vs OPA2325ID)
Design Notes
Place a 0.1 μF ceramic capacitor directly at each supply pin (V+ and V-) with a short, low-inductance path to the ground plane. Add a 2.2-10 μF bulk capacitor at the board level. Keep the input traces short and guarded when the source impedance is high, since CMOS inputs are sensitive to leakage from nearby supply rails.
For unity-gain configurations with capacitive loads, isolate the output with a small series resistor (typically 20-50 ohms for loads above a few hundred pF) to guarantee phase margin. The 10 MHz bandwidth means even short unterminated traces can resonate; maintain controlled impedance on long output runs.
The device output is rail-to-rail but the input common-mode range must be verified against the datasheet for your supply configuration; driving inputs beyond the specified range can cause phase inversion or inaccurate output. Do not exceed 5.5 V total supply. Noise figures differ between marketing material (4.6 nV/√Hz) and the family datasheet (3.5 nV/√Hz) - use the datasheet conditions for your design calculations.
