Overview
The BA82902YF-CE2 is a four-channel ground-sense operational amplifier manufactured by ROHM Semiconductor, designed for automotive applications. It operates on a single power supply ranging from 3 V to 36 V or dual supplies of ±1.5 V to ±18 V. Key electrical parameters include a gain-bandwidth product of 500 kHz, a slew rate of 200 mV/µs, and an input offset voltage of 2 mV. The device draws 700 µA of operating current per channel and provides a typical output current of 30 mA. It features a common-mode rejection ratio of 70 dB and is housed in a 14-SOP package.
Feature Summary
- Ground-sense capability allows operation with input signals extending down to the negative supply rail (VEE).
- Automotive-grade qualification compliant with AEC-Q100 standards for reliability.
- Wide operating temperature range suitable for harsh environments (-40°C to +125°C).
Applications
- Automotive sensor signal conditioning circuits
- Current sensing applications requiring ground-referenced inputs
- Battery management systems within vehicles
Procurement Notes
Verify component authenticity through authorized channels due to the NRND status. Confirm that the specific suffix matches the required pinout and packaging configuration. Ensure compatibility with existing design constraints regarding the 14-SOP footprint and thermal dissipation requirements before finalizing procurement plans.
Selection Notes
Select this component when a multi-channel solution is required for ground-referenced signal processing in automotive contexts. Consider the trade-off between the low 700 µA quiescent current and the moderate 500 kHz bandwidth. Verify that the 30 mA output drive capability meets load requirements without external buffering.
Part Context
This part belongs to the BA8290xYxxx series of standard ground-sense operational amplifiers. It shares functional similarities with other members like the BA2902YF-C but offers integrated quadruple channels in a single package. The series is characterized by CMOS technology optimized for low power consumption and wide voltage operation.
Replacement Considerations
The BA2902YF-C is a documented related part within the same family, though it typically denotes a dual-channel variant. Verify channel count and package dimensions carefully when substituting. No direct pin-compatible quad-channel replacements are explicitly confirmed in the provided data.
