Overview
The BD5291GWL-E2 is a single-channel operational amplifier manufactured by ROHM Semiconductor, housed in a WLCSP-5 package. It features rail-to-rail input and output capabilities with a supply voltage range of 1.7V to 5.5V. Key electrical parameters include a gain-bandwidth product of 3.2 MHz, a slew rate of 2.5 V/us, and an input offset voltage of 100 uV. The device operates with a quiescent current of 650 uA per channel and provides an output current of 17 mA. It supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Rail-to-rail input and output operation ensures wide signal swing even at low supply voltages.
- MOSFET input structure results in extremely low input bias current for high-impedance applications.
- Low input offset voltage design maintains accuracy in precision signal conditioning tasks.
Applications
- Sensor signal amplification
- Portable electronic devices requiring low-voltage operation
- Battery-powered instrumentation
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pinout and electrical specifications match your design requirements. Ensure the WLCSP-5 package dimensions align with your PCB footprint constraints. Confirm RoHS compliance status through official documentation before finalizing procurement.
Selection Notes
Select this component when a single op-amp with rail-to-rail performance is needed in a minimal footprint. It is suitable for designs where low power consumption and low voltage operation are critical. Consider the 100 uV offset voltage and 3.2 MHz bandwidth for signal integrity requirements.
Part Context
This part belongs to ROHM's series of low-power, low-offset voltage operational amplifiers. The BD5291GWL-E2 variant specifically utilizes a wafer-level chip-scale package to minimize board space. It is designed for general-purpose analog signal processing in consumer and industrial electronics.
Replacement Considerations
Check for direct substitutes within the BD5291 family or other single-channel rail-to-rail op-amps with similar GBP and Vos specifications. Verify package compatibility if considering alternatives outside the WLCSP-5 form factor.
