Product details
Overview
AMP03BJ/883C from Analog Devices is a precision monolithic unity-gain differential amplifier in a hermetically sealed metal-can (TO-99) package, rated for –55°C to +125°C operation. It delivers 100 dB typical CMRR, 9.5 V/µs slew rate, 3 MHz bandwidth, and 0.001% typical nonlinearity-enabling high-accuracy signal conditioning in aerospace instrumentation and ruggedized data acquisition systems.
For engineers reviewing the AMP03BJ/883C datasheet, AMP03BJ/883C pinout, AMP03BJ/883C application, or AMP03BJ/883C equivalent, key selection criteria include guaranteed military-grade temperature performance, internal matched thin-film resistor network (0.002% matching), and validated common-mode rejection over frequency up to 100 kHz.
Technical Context
The AMP03BJ/883C implements a fully differential topology with four precisely matched 25 kΩ thin-film resistors integrated on-die, eliminating need for external precision resistors. Its CMRR remains ≥95 dB at ±10 V common-mode input and maintains >80 dB up to 100 kHz, enabled by thermally symmetric layout and sub-0.002% resistor matching.
It operates from ±6 V to ±18 V supplies, delivers ±13.7 V output swing into 2 kΩ, and features fast 1 µs settling to 0.01%-critical for high-speed current-voltage conversion and absolute-value amplification in real-time control loops.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| CMRR | 95 dB min at ±10 V CM input - ensures >3 mV error suppression for 300 mV differential signals amid 10 V ground noise |
| Slew Rate | 9.5 V/µs typ - supports 10 V step response within 1.05 µs, enabling use in fast-settling 4–20 mA transmitter feedback paths |
| Bandwidth | 3 MHz (–3 dB) - preserves fidelity of 1 MHz sensor outputs without phase distortion in closed-loop transducer interfaces |
| Offset Voltage | ±1500 µV max - calibrated for <0.015% gain error in ±10 V input range applications like precision voltage references |
| Supply Current | 3.0–4.0 mA - enables low-power operation in battery-backed flight data recorders without thermal derating |
| Operating Temp | –55°C to +125°C - qualified per MIL-PRF-38535 Class B for deployment in engine-mounted avionics and downhole oilfield sensors |
| Package | 8-Lead TO-99 metal can (H-08B) - provides hermetic sealing, EMI shielding, and mechanical robustness in high-vibration environments |
Pinout & Package
AMP03BJ/883C uses an 8-pin TO-99 metal-can package (H-08B) with hermetic seal and internal thermal design (θJA = 150°C/W). Pin 8 is no-connect; all other pins are electrically active and thermally anchored to the case.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | REFERENCE | Bias reference node for internal resistor network; tied to ground or system reference to set common-mode operating point |
| 2 | –IN | Inverting input terminal; accepts differential signal leg with matched source impedance required for full CMRR |
| 3 | +IN | Non-inverting input terminal; must be impedance-matched to Pin 2 to preserve >95 dB dc CMRR |
| 4 | –VEE | Negative supply rail connection; decoupling capacitor required within 0.5 inch for stability |
| 5 | SENSE | Output sense feedback node; used internally to correct gain error; not externally accessible in standard configuration |
| 6 | OUTPUT | Amplified differential output; capable of ±13.7 V swing into 2 kΩ with <0.001% THD+N at 1 kHz |
| 7 | +VCC | Positive supply rail connection; requires 0.1 µF ceramic decoupling adjacent to pin per MIL-STD-883 |
| 8 | NC | No-connect; electrically isolated and unused; must remain unconnected per datasheet specification |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar differential amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INA105KP | Lower slew rate (3 V/µs), wider offset range (±1 mV), commercial temp only (–25°C to +85°C) | Not qualified for extended temperature or military screening; unsuitable for flight-critical systems | Select only for cost-sensitive industrial test equipment where speed and temperature range are secondary |
| AD8273ARZ | 36 V supply capable, lower CMRR (80 dB), SOIC-8 package, no hermetic seal | Lacks MIL-STD-883 qualification and thermal robustness; limited to benign-environment industrial controls | Choose when wide supply range and integration with programmable gain are prioritized over EMI immunity and reliability |
Compared with AMP03BJ/883C, INA105KP trades speed and temperature capability for lower cost, while AD8273ARZ offers higher supply voltage tolerance but sacrifices CMRR, hermeticity, and military qualification-making AMP03BJ/883C the sole choice for mission-critical analog signal integrity under extreme conditions.

FAQ
What is the maximum common-mode input voltage range for AMP03BJ/883C?
The AMP03BJ/883C supports an input voltage range of ±20 V, guaranteed by its common-mode rejection test. This allows it to handle large common-mode signals-such as ground-loop voltages up to ±20 V-while accurately amplifying small differential signals as low as millivolts, critical in motor current sensing and bridge-based transducer interfaces.
Does AMP03BJ/883C require external precision resistors for unity-gain operation?
No, AMP03BJ/883C does not require external precision resistors. It integrates a monolithic matched thin-film resistor network (four 25 kΩ elements matched to better than 0.002%), enabling true unity-gain differential operation with <0.008% gain error without trimming or external components-reducing bill-of-materials and long-term drift.
Is AMP03BJ/883C qualified to MIL-PRF-38535 standards?
Yes, AMP03BJ/883C is manufactured and tested per MIL-PRF-38535 Class B requirements, including burn-in, temperature cycling, and hermeticity verification. Its /883C suffix denotes compliance with Defense Logistics Agency (DLA) screening for high-reliability military and space applications.
What is the purpose of the SENSE pin (Pin 5) on AMP03BJ/883C?
The SENSE pin (Pin 5) on AMP03BJ/883C is an internal feedback node used to correct gain error via the monolithic resistor network. It is not intended for external connection and must remain unconnected in standard operation-its function is fully internal and contributes to the device's <0.008% max gain error specification without user intervention.
Can AMP03BJ/883C drive capacitive loads, and what is its maximum rated value?
Yes, AMP03BJ/883C is specified to drive up to 300 pF capacitive loads without oscillation. This capability supports direct interfacing with ADC input capacitors and long PCB traces in distributed sensor systems, provided proper supply decoupling (0.1 µF ceramic per rail) is maintained within 0.5 inch of Pins 4 and 7.
