Overview
The BA10324AFJ-GE2 is a quad ground sense operational amplifier manufactured by ROHM Semiconductor. It operates with a single power supply ranging from +3.0V to +32.0V. The device features input and output voltage ranges that extend to the ground rail (VEE). Key electrical parameters include a typical circuit current of 0.5mA per channel, a large signal voltage gain of 100dB, and a gain-bandwidth product of 1MHz. It supports an operating temperature range from -40°C to +85°C and is housed in a SOP-J14 package.
Feature Summary
- Quad configuration providing four independent ground-sense operational amplifiers within a single package.
- Capable of input and output signal operation near the ground potential (VEE) when powered by a single supply.
- Designed for wide operating supply voltage ranges, supporting applications from low-voltage to higher-voltage systems.
Applications
- General-purpose analog signal conditioning circuits requiring ground-referenced inputs.
- Sensor interface circuits where signals swing close to the negative supply rail.
- Battery-powered devices utilizing single-supply architectures.
Procurement Notes
Verify the specific suffix and revision level against the latest official datasheet before finalizing procurement. Confirm that the SOP-J14 package dimensions match the target PCB footprint requirements. Ensure that the operating temperature range meets the environmental specifications of the end application. Cross-reference the RoHS compliance status with current regulatory standards for the destination market.
Selection Notes
Select this component when a quad amplifier configuration is required with ground-sense capabilities on a single supply. It is suitable for designs prioritizing cost-effectiveness and standard performance over high-speed or precision applications. Consider the 1MHz bandwidth and 100dB gain as sufficient for general audio or low-frequency signal processing tasks.
Part Context
This part belongs to ROHM's BA103xx series of operational amplifiers, which are characterized by their ability to operate with inputs and outputs near the ground rail. The series is designed for general-purpose use in consumer electronics and industrial equipment where single-supply operation is preferred. The 'AFJ' designation typically indicates the specific package type and material composition compliant with industry standards.
Replacement Considerations
Direct replacements should be sought among other quad ground-sense op-amps with similar supply voltage ranges and pinouts. Verify compatibility regarding input offset voltage, bias current, and package dimensions. Consult manufacturer cross-reference guides for validated alternatives that maintain functional equivalence in single-supply ground-referenced applications.
