Typical Applications
OPA2192IDR is suitable for 6 applications: Industrial Data Acquisition, Sensor Signal Conditioning, Precision Active Filters, Battery-Powered Instrumentation, Transimpedance Amplifier Front End, Automotive and High-Voltage Analog Rails.
Industrial Data Acquisition
The OPA2192IDR fits industrial DAQ front ends because its 4.5V-36V supply range tolerates industrial 24V rails, while e-trim calibration keeps offset errors negligible in gain-of-10 to gain-of-100 sensor amplifiers. Its 10MHz GBW and 20V/us slew rate allow it to drive successive-approximation ADC inputs directly without an additional buffer stage. Placed between a signal conditioner and an ADC such as the ADS1220, it preserves measurement accuracy while adding no switching artifacts, though power dissipation rises at high supply and load.
Recommended
Sensor Signal Conditioning
Bridge, thermistor, and pressure sensor outputs are high-impedance and small-signal; the OPA2192IDR's low input bias current and e-trim low offset preserve microvolt-level signals without external trimming. The rail-to-rail input accommodates sensors that swing near ground on single-supply 5V or 24V systems, and the rail-to-rail output maximizes the signal range into an ADC. Using 1% gain-setting resistors with this amplifier yields measurement channels that stay within spec across the -40C to +125C industrial range.
Recommended
Precision Active Filters
Active low-pass and anti-aliasing filters need amplifiers with stable GBW, low offset at DC gain, and adequate slew rate for signal peaks. The OPA2192IDR's 10MHz GBW supports Sallen-Key and multiple-feedback topologies with corner frequencies into the hundreds of kilohertz while its e-trim offset keeps DC errors in the filter passband negligible. The 36V rating allows filters on +/-15V analog rails common in industrial control systems, delivering higher SNR than 5V-only designs.
Recommended
Battery-Powered Instrumentation
Portable instrumentation benefits from the OPA2192IDR's single-supply operation down to 4.5V and rail-to-rail I/O, which maximizes dynamic range from a single lithium or 4-cell pack. The precision offset and low bias current allow direct connection to high-impedance electrodes and sensors, eliminating calibration steps. Pairing it with a low-Iq buck converter keeps total system quiescent draw low; the trade-off versus nanoamp-class amplifiers is higher quiescent current in exchange for 10MHz precision bandwidth.
Recommended
Transimpedance Amplifier Front End
Photodiode and current-output sensor front ends demand low input bias current so that measured current is not shunted by the amplifier, and low offset voltage to set the zero-signal output accurately. The OPA2192IDR addresses both with e-trim precision while its 10MHz GBW supports feedback resistors in the megaohm range with usable bandwidth. Stable operation with large feedback capacitance and clean layout keep noise low; verify phase margin with the datasheet noise-gain stability guidance for high-gain designs.
Recommended
Automotive and High-Voltage Analog Rails
While the standard OPA2192IDR is not AEC-Q100 qualified, its 36V rating suits 24V industrial and clamped automotive auxiliary rails in prototype and industrial-adjacent systems. Rail-to-rail inputs handle ground-referenced and battery-referenced signals alike, and e-trim offset stability over -40C to +125C keeps signal chains accurate across temperature extremes. Use it ahead of isolated amplifiers such as the AMC1306M25 for measurement chains that eventually bridge isolated domains in traction or grid equipment.

Key Differentiators
- 36V supply tolerance with precision bandwidth (vs LTC2051CMS8#PBF)
- Higher bandwidth than OPA2197IDR at similar DC precision (vs OPA2197IDR)
- Rail-to-rail input advantage over AD824AD (vs AD824AD)
Design Notes
RRIO amplifiers with dual differential input pairs exhibit an input offset transition region near the positive rail. If your signal common-mode sweeps through this region in high-gain precision circuits, a small offset step may appear. Reference signals near mid-supply or consult the OPA2192 datasheet offset-vs-common-mode curves before committing to a design that operates within ~2V of the positive rail.
Place 100nF ceramic decoupling capacitors within 2mm of the V+ (pin 8) and V- (pin 4) pins, with a 2.2uF-10uF bulk capacitor nearby. Keep the high-impedance input traces (pins 2, 3, 5, 6) short and guard them with a driven ground shield when source impedance exceeds 100kohm to limit leakage and noise pickup on the SOIC-8 footprint.
With 10MHz GBW, the OPA2192 can ring or oscillate in low-gain circuits driving capacitive loads above roughly 100pF. Isolate capacitive loads with a small series resistor (10-50 ohm) at the output, or use an in-loop isolation network. Verify unity-gain stability in voltage-follower configurations on your actual PCB layout, not just simulation.
